Chinese name chemical machinery English name chemical engineering &；; The bimonthly introduction to machinery, Chemical Machinery, is a technical periodical jointly sponsored by the Institute of Chemical Machinery of the former Ministry of Chemical Industry and the Chemical Machinery Professional Committee of China Chemical Industry Society. Founded in 1974, bimonthly, with the font size 16, and publicly issued at home and abroad. Since its publication, this journal has won the second prize of National Excellent Sci-tech Journals, the third prize of Scientific and Technological Progress of the Ministry of Chemical Industry, the first prize of Excellent Information Achievements in Chemical Industry System and the title of Excellent Sci-tech Journals in Gansu Province. It is one of the national Chinese core journals and three key contact journals designated by the former Ministry of Chemical Industry, and is listed as the source journals of China's scientific papers statistics, China's academic journal evaluation database, China's scientific citation database and China's academic journal CD-ROM. Based on China, chemical machinery has also gone to the world. Chemical machinery is included in Chemical Abstracts (CA), Engineering Index (EI), Chemical Engineering and Biology Abstracts (CEBA) and Metal Abstracts (MA) jointly published by Britain and America. The editorial department of chemical machinery also has business contacts and exchanges publications with 27 magazines in 14 countries and regions. This shows that "Chemical Machinery" has entered the world of chemical journals at the same time of establishing the core journals of chemical industry in China.
