Iron Slag Recycling Method,Steel Slag Processing Plan

Slag recycling - recovery

In an LD oxygen converter the molten pig iron is then processed together with steel scrap into crude steel. In the purely scrap-based production variant, the raw steel is produced by recycling steel scrap in an electric arc furnace. Depending on which of these production processes is used, one speaks of blast furnace slag or steelworks slag.
