What Is a Steel Mini Mill? Career Trend

Sep 03, 2019 A steel mini mill is a facility which produces steel products from recycled scrap metal. Unlike integrated steel mills, which make new steel from iron ore in a blast furnace, mini mills melt and refine scrap steel using electric arc furnace (EAF) technology. According to a U.S.

U.S. and Global Iron and Steel Industries Center for

Aug 20, 2019 Iron and steel mills comprise integrated producers and mini-mills. Integrated steel producers generally begin the process by reducing iron ore to molten pig iron in a blast furnace, although some buy slabs and coke on the open market to reduce costs. The pig iron is then combined with scrap in a basic oxygen furnace to make molten steel.
