Recent Progress in MaterialsDuring the steelmaking process, various slags are produced as byproducts of the steelmaking process [1]. The first stage of the production of steel is blast furnace (BF) steelmaking, in which raw iron ore is converted into pig iron. The pig iron must be refined by either basic oxygen steelmaking (BOS) or electric arc furnace (EAF) steelmaking. Both of these processes produce slags as a by ...
Steel Slag | TarmacSteel slag is produced during the steel making process where, after air cooling, a dense rock material is processed and sized into specific products suitable for diverse appliions. These include construction aggregates, rail ballast, agricultural soil amendment, in the manufacture of Ordinary Portland Cement and as an environmental remediation material. The durability and surface properties ...
CNAThe invention relates to a method for pelletizing refined iron powder extracted from steel slag for converter steel making. The method is characterized by comprising the following steps of: performing magnetic separation, ball milling and sorting on converter steel slag with full iron grade of over 20 percent to obtain a powdery ironcontaining material, refined iron powder, with iron grade of ...

Iron And Steel ProductionThe production of steel in an EAF is a batch process. Cycles, or "heats", range from about 11/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrap steel is charged to begin a cycle, and alloying agents and slag materials are added for refining. Stages
