In ironmaking production, maintaining the stability of blast furnace operations is crucial. Key parameters influencing this stability include furnace temperature, ore batch weight, slag alkalinity, charge ratio, wind pressure and temperature, and top pressure. Furnace temperature Maintaining stable furnace temperature helps keep the drop zone height proper, stabilize the differential…

Under the condition of using solid carbon fuel (coke + pulverised coal) in conventional blast furnace, reducing carbon fuel consumption is the most direct and effective measure to reduce CO2 emission. In the iron and steel industry, by around 2030, the fuel ratio of blast furnace should be generally reduced…

Blast furnace is a black box, how to understand the various changes within the blast furnace well, one way is to reference the anatomy of the blast furnace, supplemented by a variety of theoretical calculations and practical experience to deduce the changes within the furnace;  another way is to apply some visualisation technology to…

Blast furnace charging operation refers to the control of the position and thickness of the furnace charge in the blast furnace production process, so as to adjust the key technical and economic indicators such as the permeability of the charge column and the utilisation of gas. The charging system is…
