Chromium and chromium are often present in the ore in the state of FeO.Cr2O3), and the reduction rate of chromium in the blast furnace can reach 80% to 95%. Chromium is a beneficial element in steel and can increase the corrosion resistance of steel. Addition of chromium nickel steel can be made of stainless steel, nickel-chromium, chromium in addition can increase the strength of metals. Little effect on the chrome ore in blast furnace, steelmaking operation but has an impact, because the raw iron and chromium in the steel-making process is oxidized into the slag, the slag becomes very sticky bad operation . Therefore, it is hoped that the iron content in the pig iron is ≤0.4%-0.6%, which requires that the chromium content in the iron ore is not higher than
