Steel slag is the by-product during the separation of molten steel from impurities in the steel-making furnace. The basic oxygen furnace (BOF) slag, electric arc furnace (EAF) slag, and ladle furnace (LF) slag are three major types of SS produced in the steelmaking processes.As drawn in Fig. 2, BOF slag and EAF slag are both produced …

BOS Slag. Process. When molten iron (referred to as "hot metal") from the blast furnace is to be converted into steel, the main tasks are the removal of carbon, silicon and phosphorus. The LD (Linz-Donawitz) process is by far the most widely used, and takes its name from the towns where it was developed.
