ABOUT STEEL | worldsteel

Steel made in an EAF uses electricity to melt recycled steel. Additives, such as alloys, are used to adjust to the desired chemical composition. Electrical energy can be supplemented with oxygen injected into the EAF. Downstream process stages, such as casting, reheating and rolling, are similar to those found in the BF-BOF route. About 28.9% of steel is produced via the EAF route.Scientific Research and Essays - modelling and forecasting,,Keywords: Load forecasting, regression analysis, top-down, bottom-up, steel mills.
