As a model of supply side structural reform, MCC group has made every effort to build the world's first metallurgical construction national team, comprehensively promoted the supplement of short plate and forging long plate, formed the integrated advantages of the whole metallurgical industry chain of scientific research, survey, design, construction, operation and maintenance as well as equipment manufacturing in the whole process of steel manufacturing, and stably occupied 90% of the domestic and 60% of the global metallurgical market. In 2020, MCC has successively signed more than 20 major steel engineering contracts worth more than 1 billion yuan, including Zhongtian steel, Zhongxin steel, Guangxi Fangchenggang steel, Shandong Rizhao steel and Shandong Linyi steel special steel. In terms of greening, it won the bid for the world's first demonstration project of hydrogen energy development and utilization, plant design engineering, and explored the best way for the world's steel industry to develop a low-carbon or even "zero carbon" economy; in terms of intelligence, the former integrated intelligent management and control center project of Maanshan Iron and steel, which has the largest scale, the largest production lines and the highest degree of integration in the industry, has realized the transformation of ironmaking production from experience to experience The intelligent control center has been completed and put into operation on December 15, 2020. In terms of internationalization, it signed the contract of high-end electrical steel continuous annealing unit for new energy vehicles with Russian steel giant nlmk, and signed the general contract of Hefa Rongju steel converter with Vietnam Hefa group, continuously promoting the independent core technology and installation Dexin steel, Indonesia's first long flow plain carbon steel production base designed and constructed by the general contractor, has been put into operation successfully, driving the market development of key customers in Southeast Asia.
