Character experience
1989, 19 years old Zheng Jiuqiang went to work. At that time, visual inspection of molten steel temperature was the most critical technology in steelmaking. The steelmaking temperature is between 1600 ~ 1700℃, and the judgment error of tapping temperature cannot exceed 5℃. In order to cultivate a pair of "golden eyes", he stared at one furnace after another until his eyes were red and swollen. He won the championship in the technical competition of the whole factory that year. At the age of 23, he was promoted to be the furnace chief, becoming the youngest furnace chief in the company's history, and won the national steelmaking technical competition at the age of 32. 1in may, 993, Zheng jiuqiang joined the China * * * production party.
In 2007, he was elected as the representative of the 17th National Congress of China Producers' Party.
Main story
job performance
Zheng Jiuqiang initiated the smelting operation method of low-alloy steel, which created huge economic benefits and made outstanding contributions to the technical progress of the industry, and was known as "the first steelmaker in China".
1989, 19-year-old Zheng Jiuqiang graduated from a technical school and was assigned to the converter workshop of the first rolling mill of Tangshan Iron and Steel Company as a former furnace worker. After working for less than four years, he became the youngest "steelworker" in the history of Tangshan Iron and Steel Company. After that, Zheng Jiuqiang overcame the technical difficulties in iron and steel smelting through theoretical study and practice, and made outstanding contributions to the technical progress of the company and even the industry.
1999, Tangshan iron and steel co., ltd introduced the 150-ton oxygen converter with the largest production capacity and the most advanced technology in Hebei province at that time, and the party Committee of the factory put the burden of smelting the first heat steel of the new converter on Zheng Jiuqiang. During that time, he went to bed at 2 am and got up at 6 am every day. After 2 1 day production preparation, on June 29th, the first batch of qualified molten steel was discharged, and Tangshan Iron and Steel Company entered the era of large converter.
He pioneered the smelting operation method of low alloy steel, and after being popularized in the whole plant, he created more than 8 million yuan of economic benefits that year. By adjusting the process, he promoted the continuous reduction of rolling cost and the improvement level reached the leading level in the industry. Since 20 14, the benefit has reached 230 million yuan. He also summed up the advanced operation methods, which increased the service life of the converter from 6,000 heats to more than 6,543.8+0.7 million heats, and the whole furnace was not replenished, creating benefits of more than 20 million yuan every year. He actively promoted clean production, realized the recycling of waste heat, waste gas, waste water and waste residue, and the utilization rate of secondary energy reached 70%, making Tangshan Iron and Steel Company known as "the cleanest steel plant in the world".
school achievement
Zheng Jiuqiang not only always pays attention to summing up smelting operation methods, but also pays attention to the sublimation of practice. His papers such as "Application of Magnetic Separation Steel Slag in 150 Ton Converter Smelting" and "Desulfurization in Converter Steelmaking" were published in different magazines, which caused great repercussions in the same industry. Many units have improved their work efficiency to varying degrees after practicing according to the theory put forward by Zheng Jiuqiang.
famous
He has successively won the first place in the national vocational skills competition for converter steelmaking workers, the national youth post expert, the national technical expert, the Chinese Youth May 4th Medal, and the National May 1st Labor Medal.
On July 28th, 2006, General Secretary Hu Jintao, who works in Tangshan, received him cordially.
In 2007, he was elected as the representative of the 17th National Congress of the Communist Party of China, the candidate of national moral model, and the honorary title of moral model in Hebei Province.
