biography
Liu,1was born in Nanchang county, Jiangxi province in June, 1925. 1 1,1graduated from the civil engineering department of Nanchang university in June, 1950 (it was renamed Nanchang university after the founding of the People's Republic of China,1in June, 1952, the national colleges and universities were adjusted and the school was cancelled.
When Liu University graduated, it was People's Republic of China (PRC) that had just been established, and all kinds of architectural talents were badly needed. He was full of infinite love for the new China, and devoted himself to the tide of economic recovery and construction as soon as he graduated.
From 1950 to 1958, Liu worked in the design department of Northeast Ministry of Industry, civil engineering design company, design company of Heavy Industry Department and Shenyang Branch of Nonferrous Metallurgical Design Institute, engaged in civil engineering design of non-ferrous metal projects, and served as the design team leader and site design representative. During the period of 1965, he served as the deputy chief designer of the reconstruction and expansion project of Shenyang Nonferrous Metals Processing Factory (hereinafter referred to as Shenyang Factory), responsible for organizing the construction drawing design and handling the technical problems on site. During the period, after investigation and demonstration, on the basis of the old factory building in the puppet period the day before yesterday, he put forward a construction plan for rational utilization of the original factory building, equipment and auxiliary facilities, which not only saved investment, but also shortened the production stoppage time and construction period, and was well received by the construction unit.
From 65438 to 0958, Liu served as the site design team leader of Luoyang Nonferrous Metals Processing Factory (later Luoyang Copper Processing Factory, now Luoyang Copper Processing Co., Ltd., hereinafter referred to as "Luoyang Copper Processing Co., Ltd."), and was transferred to Beijing Nonferrous Metallurgy Design Institute soon, and his work remained unchanged. Luotong is one of the 156 key projects built during the first five-year plan of China's national economic and social development. The main works are all designed and provided with complete sets of equipment by the former Soviet Union. The task of the design team is to design the ancillary works of the factory, assist Soviet experts in design interpretation and cooperate with the construction and installation, build the factory on this basis and master the engineering design technology. Later, due to the deterioration of Sino-Soviet relations, the Soviet side withdrew its experts and stopped supplying all drawings and materials in August 1960, which brought the project to a standstill. In the face of great difficulties, at the critical moment when the national interests were seriously damaged, Liu Yiran led all the designers, courageously shouldered all the design tasks despite difficulties and hardships. After more than five years' efforts, the factory was finally completed and put into operation at 1965.
In order to meet the needs of large-scale third-line construction, 1964, the Ministry of Metallurgy decided to establish Luoyang Nonferrous Metallurgy Design Institute (now Luoyang Nonferrous Metal Processing Design and Research Institute, referred to as Luoyang Institute for short), which mainly undertakes the design of nonferrous metal processing engineering. Liu was also transferred to the hospital until he retired.
Since its establishment, Luoyang Institute has successively undertaken the design tasks of four large-scale processing projects: Southwest Aluminum Processing Factory (now Southwest Aluminum (Group) Co., Ltd., referred to as Southwest Aluminum), Northwest Aluminum Processing Factory, Northwest Copper Processing Factory and Baoji Nonferrous Metal Processing Factory (referred to as Baoji Factory). In order to speed up the design progress, a site design team was set up to complete the design and construction methods under the unified leadership of the construction headquarters. From 1964 to 1966, Liu served as the deputy director of the general office of the hospital. As the main technical person in charge, he assisted the dean to uniformly deploy the strength in the hospital and participated in the review and discussion of some major design schemes. After 1967, he served as the captain of two field design teams, Southwest Aluminum and Baoji Factory, which coincided with the "Cultural Revolution". He overcame the "Left" interference and led everyone to successfully complete the design tasks of these key projects.
From 1972 to 1977, Liu served as deputy director and planning section chief of the production office. Due to the interference of the "Cultural Revolution", it is difficult to maintain the normal working order. Liu was criticized and hit several times for insisting on production. Regardless of his personal safety, he stuck to his post and worked hard to complete the national third-line construction and design tasks.
Liu Yu 199 1 retired in April. Due to his outstanding contribution to the development of China's non-ferrous metal processing industry, he began to enjoy special government subsidies on 1993.
Major achievements
To lay a solid foundation for the sustainable development of Luoyang Institute under the new situation.
From 1978 to 1985, Liu was in charge of technical management and presided over the work of Luoyang Hospital. This period coincided with the beginning of China's reform and opening up. Together with his colleagues, he seized this favorable opportunity, made bold reform and forge ahead, so that the design level and business scope of Luoyang Hospital were rapidly improved and expanded. In the design of non-ferrous metal deep processing, the advanced technology and equipment in the world at that time were adopted, and the engineering design of three key technical transformation projects, namely Northeast Light Alloy Processing Factory (now Northeast Light Alloy Co., Ltd., referred to as Dong Qing for short), Southwest aluminum strip and Luotong copper strip, was completed. We have undertaken the technical introduction and design work of several projects, such as aluminum strip, aluminum foil, building aluminum profile, aluminum cans and aluminum foil soft packaging, aluminum plate for printing, copper strip and copper wire blank, which has made the production of copper and aluminum processed materials in China reach a new level in variety and quality. In civil architecture and municipal engineering, it has broken through the limitation of serving only non-ferrous metal processing enterprises, and has successively undertaken the design of large department stores, high-rise hotels, office buildings, hospitals, garden buildings and water sources of the Yellow River. During this period, the projects that completed the design and won awards include: aluminum profile project of Tianjin Aluminum Alloy Factory 1984 won the National Excellent Design Gold Award, Dong Qing Hot Rolling Technical Transformation 1987 won the National Excellent Design Gold Award and the National Science and Technology Progress Second Prize, and Zhengzhou Yellow River Water Source Project 1990 and 1 won the National Science and Technology Progress Second Prize respectively.
In the process of organizing and leading these projects, Liu not only participated in making major plans, reviewing design documents and solving technical problems on the spot, but also attached great importance to improving the design level of technicians by introducing project design and training, and organized personnel who went abroad for inspection and participated in foreign technical exchanges to introduce foreign advanced technologies or write technical materials of their major; Pay attention to maintaining the stability of the main designers of each project in the work arrangement; After the design is completed, arrange designers to participate in the whole process of construction, installation and debugging, so that they can accumulate more complete technical experience.
1982 With the support and cooperation of Liu, he undertook the design task of aluminum strip project 1400 mm four-high irreversible aluminum strip mill. This mill is the first modern aluminum strip mill designed and manufactured by China, reaching the technical level of foreign countries in the late 1970s. The first trial production of the mill was successful, and the product accuracy exceeded the technical index of tolerance of 0.005 mm when the minimum thickness of rolled material was 0.2 mm The successful design of the mill not only fills the gap of modern aluminum strip mill in China, but also greatly improves the confidence of designers and leaders. On this basis, he established the Equipment Management Department of Luoyang Institute in early 1985, and began to operate the design, manufacture, installation, commissioning, technical service and technical consulting agency of imported equipment that contracted complete sets of special equipment for non-ferrous metal processing, and directly transformed the professional design technology and development capability of Luoyang Institute into various processing equipment needed for production, which was rare in large domestic design institutes at that time. After more than ten years of development, one-stop equipment contracting has expanded from the initial single aluminum strip rolling mill to a multi-functional service system including various high-precision aluminum strip foil rolling mills, copper strip rolling mills, copper-aluminum hot rolling mills, copper-aluminum semi-continuous casting machines, horizontal continuous casting machines, continuous casting and rolling mills, pipe and bar stretching equipment and other auxiliary machines, tungsten-molybdenum rolling mills and various special equipment such as melting furnaces, heating furnaces and heat treatment furnaces. The equipment management department, which used to have only a few people, has developed into an equipment design and research institute composed of equipment, electricity, hydraulics, assembly plants and other entities. The annual general contracting income exceeds one-third of that of Luoyang Institute and has become a major economic pillar. The achievements of equipment research institute today are inseparable from Liu's successful decision.
Talent is the foundation of the industry. When Liu was in charge of the technical work in the hospital, he attached great importance to improving the professional level of technicians and made unremitting efforts as an important work. In order to solve the problem of designers' foreign language neglect, 15 full-time English and Japanese classes were held from 1978 to 1985, which improved the foreign language level of nearly half of the technicians. In view of the more and more important role of scientific management, technical economy and computer in design, professional study classes on enterprise management, technical economy and budget estimation were held respectively, and much-needed technical economy and budget estimation personnel were trained. A computer center was established and several CAD training courses were held, which promoted the wide application of computers in design. Establish a professional application software development team by sending and inviting. Due to the attention of leaders, Luoyang Institute's computer application technology is at the forefront of various design institutes of nonferrous metal systems.
Make important contributions to the design and construction of four non-ferrous metal processing plants.
Since Liu joined the work, he has forged an indissoluble bond with non-ferrous metal processing projects. He personally participated in and presided over the design of Shenyang Factory, Luotong, Southwest Aluminum (one-step project) and Baoji Factory, and made important contributions to the project construction.
Roton is a large-scale processing plant in the former Soviet Union, providing design and complete sets of equipment. The designed annual production capacity is 53,000 tons of copper and 1200 tons of magnesium. 1958 started construction,1August 960 the Soviet side tore up the agreement. As the leader of the project design team, Liu immediately led the design team members back to the site after the country determined the policy of self-reliance and continued construction. Under the unified command of the factory building leading group, he cooperated with the construction unit, overcame many difficulties without technology and drawings, and finally did not reduce the original level of technology and equipment. During this period, as the leader of the field design team, he played an important role in the following four aspects: ① Organizing designers to digest Soviet drawings and equipment data, and finding and modifying a large number of mistakes in the original design. After the project returns to work, participate in quality inspection, installation and debugging with designers, and deal with various technical problems, especially when dealing with major technical problems related to design. He is the main decision maker. (2) Two production systems, copper electrolysis and magnesium plate rolling, were added during the construction of the workshop, which made the original design of the Soviet Union need to be redone in addition to the three main workshops; He presided over the design of eight large-scale special equipment and other facilities that were not delivered when Soviet experts withdrew. ③ Some large-scale and high-strength steels, special building materials and domestic supporting equipment and parts used in Soviet design were difficult to solve at that time, and the design team modified and replaced them according to China standards, specifications and supply conditions. (4) Due to the long construction period and great changes in the middle, the engineering and technical data are quite confusing. In order to facilitate the management and organization of designers in the future, it took 1.5 years to collect and sort out the design technical data in different disciplines and stages, and established a complete set of engineering files for the factory. During nearly seven years of on-site design work, he participated in the whole process of design, construction and trial production of Luotong project, accumulated experience in organizing and leading large-scale engineering design, and also led and trained a group of design technical backbones.
Southwest aluminum industry is a key third-line construction project designed and manufactured by China itself, and it is also the largest comprehensive aluminum processing plant in China so far. The preliminary design of the first phase of the plant was completed on 1965. 1April, 966, due to the change of the site, all the design needs to be restarted. 1From July, 1966 to August of the following year, Liu served as the branch secretary of the site design group, mainly involved in the formulation of the design scheme of the extrusion production area and the organization of the construction drawing design. Because the area is located in a depression surrounded by mountains on three sides, the factory area is small, and the original preliminary design configuration cannot be realized. He led everyone to take technical measures such as merging production workshops, arranging auxiliary facilities step by step, integrating underground pipe networks of various disciplines, setting anti-skid columns to deal with unstable slopes, and using pile foundations for column foundations and heavy equipment foundations of the factory to avoid uneven settlement of filled soil foundations, which solved a series of technical problems brought by building factories in mountainous areas.
Baoji factory is a comprehensive rare metal processing factory which mainly produces titanium, zirconium, tungsten, molybdenum and other processed materials. The large-scale equipment of the factory is imported from abroad. The factory is located in the deep mountain valley and the back mountain is close to the river. These characteristics determine that design must be closely combined with production and construction, and the general layout and design scheme of each specialty must be adapted to local conditions. On July 1969, Liu went to the site as the deputy head of the design team (led by the industrial propaganda team). Although the project construction has entered the middle stage, due to the changeable scheme, the project design is in a passive situation that lags behind the construction progress. During this period, he organized designers to cooperate with the construction, installation and debugging. Because foreign businessmen can't go to the site, all the problems of installation and debugging of imported equipment are solved by the designer in combination with construction and production. He organized the construction drawing design of main workshops such as 3 150 ton extruder and 20-high rolling mill, in which the production area of extruder workshop is very contradictory to the long and narrow factory area. In order to reduce the engineering quantity of mountain opening and river filling, vertical transportation equipment is added in the design. The configuration scheme of building the workshop on two adjacent steps according to the working procedure solves this problem well. He also reviewed, revised and supplemented all the completed construction drawings, and on this basis, compiled a set of factory-wide design scheme, the depth of which is equivalent to the expansion of the factory's preliminary design.
