Basics of slag production Article on the slag industry

Oct 27, 2011Slag from the production of ferrochrome is also included here; this material is produced in substantial tonnages and the main use of ferrochrome is in the steel industry. Slags also arise from other processes, particularly the smelting of non-ferrous metals, but these materials can be very different and each needs to be studied individually.

Steel Slag an overview ScienceDirect Topics

BBOF slag (BOFS) is produced in the steelmaking process by using the molten iron coming from the BF. In the second method, slags are generated in the scrap-based steel industry. The first stage of the scrap-based steel industry production generates EAF slag (EAFS) and a second stage is performed to refine the molten steel.

Iron and Steel Slag Statistics and Information

Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina.

Modified steel slag for effect prolongation of calcium

Aug 01, 2020The annual steel slag production reached more than 100 million tons in China, and its utilization rate is only 29.5%. In contrast, the utilization rate of steel slag in industrial countries is more than 85% (Guo et al., 2018). In fact, steel slag is very versatile for environmental protection or for resource recovery purpose.
