Smart manufacturing in the steel industry has entered a new model of green, low-carbon, and smart. This article details the development of a large-scale steel mill in China through more than 30 years of research and development and production practices that have developed cutting-edge metallurgical technologies that are green and environmentally friendly and have low emissions.

1. Oxygen-enriched blast furnace smelting

Blast furnace high-oxygen-enriched natural gas or coke oven gas injection technology reduces carbon emissions by more than 50% compared with traditional blast furnaces.


 2. Non-blast furnace ironmaking (HIsmelt)

HIsmelt ironmaking process is one of the smelting reduction ironmaking technologies that have realized industrialized production. The process technology is gradually mature and has obvious environmental advantages. It is currently the world’s most environmentally friendly and low-emission cutting-edge metallurgical technology. It has a very high level in the international metallurgical field. Attention.


HIsmelt reduces environmental impact and eliminates coking, sintering and pelletizing processes through process innovation. Compared with traditional metallurgical processes, this technology can reduce CO2 emissions by more than 15%, SO2 emissions by 90%, and NOx emissions by 50%, and basically curb the second The production of pollutants such as oxin, tar and phenol.


3. Short process

The hydrogen-based direct reduction-electric furnace short process production line can greatly reduce the CO2 emissions per ton of steel in the whole process and achieve the goal of carbon neutrality. Using hydrogen-based direct reduction technology to produce sponge iron, power furnace or converter steelmaking. Through the production of sponge iron, it can cope with the future reduction of blast furnace molten iron output, and adapt to the shortage of scrap steel and the needs of smelting high-quality steel.
