China's iron and steel metallurgy equipment technology export new progress
The construction of "One Belt, One Road" will provide an important development opportunity for China's steel enterprises to "go out". With the rapid development of China's national economy and iron and steel, machinery industry, China's iron and steel plant design, equipment manufacturing, construction, production technology and other aspects have made great progress. China's iron and steel metallurgical equipment technology exports have a strong foundation, but also made a lot of new progress, of course, there is also a lack of innovation (few of China's self-developed equipment, technology), there are shortcomings (in the blast furnace, coking, sintering, pellet, better, large-scale steelmaking, rolling equipment, worse), management is not smooth (in the foreign projects of the domestic companies concerned in the disordered competition, the internal friction is very large) and other issues, to be constantly improved! In recent years, China's iron and steel metallurgical equipment technology.
In recent years, China's iron and steel metallurgical equipment technology progress mainly includes the following six aspects.

Starting to export iron and steel metallurgical equipment and technology to developed countries
There are the following two cases of exporting iron and steel metallurgy equipment and technology to developed countries: firstly, China designs and manufactures them independently; in addition to the well-known products mentioned above, there is also the 185m2 sintering machine independently researched and developed by CMT Changtian and exported to Nippon Steel & Sumitomo Metal and Wakayama Plant in Japan, which has successfully gone into operation, and the project is a general contracting for designing and purchasing. The technology of 6m high coke oven with carbonisation chamber was exported by CMT Coking & Resistance to Sumitomo Metal Corporation in Japan. The No.6 Blast Furnace (6000m3) Gas System Modification Project of POSCO Gwangyang Plant in South Korea commissioned CMT Jingcheng to design, supply and provide technical services, and the adoption of Dry Dust Removal and Blast Furnace Gas Alkali Spraying and De-chlorination System has been successfully put into production. The 1.5 million tonnes/year FINEX engineered mill non-dehydration self-circulation system developed and supplied to POSCO by CMT Jingcheng has been put into operation and is running normally, with the capacity of 2×50 tonnes/year and the oxygen content is controlled at 8%-9%.
Secondly, it cooperates with famous manufacturers in developed countries to export to third countries. For example, China First Heavy for the Italian company Alverdi to undertake the world's first headless casting and rolling thin steel strip production line machinery and equipment (including eight mills) project by Siemens voestalpine general contracting. The project of providing F4, F5 and F6 finishing mill stand machinery and equipment for ArcelorMittal's 2250mm hot strip mill in Poland by China Second Heavy was general contracted by Siemens.
Engineering Consultancy and Technology Export
Main Cases: The project of master plan contract for KPO 10 million tonnes new steel base of Tata Steel in India was signed between CMT SEDI and Tata Steel India.
The consulting contract for the feasibility study of 3 million tonnes steel plant for the first phase of China-Pakistan New Energy Steel Project was signed between CMT Jingcheng and China-Pakistan New Energy International Investment Company.
Chinese companies build steel plants overseas to drive the export of iron and steel metallurgical equipment and technology.
Main cases: Shougang Group and a local Malaysian company built a new 3 million tonnes/year steel joint venture in a special economic zone in eastern Malaysia. Castle Peak Group builds ferronickel and stainless steel plant in Indonesia, which will build eight ferronickel production lines and ancillary projects, two 150,000 kW thermal power generation projects, with an annual output of 600,000 tonnes of ferronickel. The scale of stainless steel plant is 3 million tonnes/year, and will build 1780mm hot strip rolling production line, and signed design contract with CMT Orient.
In recent years, China's iron and steel metallurgical equipment and technology exports, although there is greater progress, but in general, the scale is not large and large-scale equipment, small and medium-sized equipment; less advanced equipment, more common equipment; less independent innovation equipment, less well-known product companies, more general products. Fundamentally, to dare to be good at innovation, improve the independent design and manufacturing capacity, and strive to create more well-known brands and enterprises. In short, to improve the independent design and manufacturing capacity, is to improve China's iron and steel metallurgical equipment technology exports the fundamental way.
Make full use of the "One Belt, One Road" strategic opportunity and China's enterprises to invest in overseas plant opportunities to expand the export of iron and steel metallurgical equipment technology. At present, we have not done enough in this regard, and we need to learn from our experiences and lessons, and make positive progress, especially in the current situation of China's iron and steel overcapacity, we should create conditions for relocating the whole iron and steel plant overseas.
Strengthen the promotion of China's iron and steel products and enterprises, improve the mechanism of exporting iron and steel metallurgical equipment and technology, so that the general contracting unit, design unit, manufacturing unit and construction unit are well combined, strengthen the coordination and management, and try to minimise the situation of disorderly competition among Chinese enterprises in overseas projects.
Further development of foreign engineering design and consulting (including production and construction consulting) in order to drive the export of iron and steel metallurgical equipment technology.
