Abstract With large-scale mining of ores all over the world, superior iron ore resources with high quality are facing the problems of exhaustion. As a consequence, the price of iron ore is soaring, which forces a large number of domestic steel enterprises to increase the ratio of cheap infe-rior iron ore charged in the blast furnace. Among the inferior iron ore, a great amount of chromium-containing ore such as low-grade domestic ore, laterite ore and nickel ore, is charged in the blast furnace, leading to the generation of a large amount of hot metal containing a moderate concentration of chromium (w(Cr)=0.2%—1.0%). Besides, the production of stainless steel in China continually expands, accompanied by the accumulation of a large number of stainless steel scrap and returning material. The utilization of these secondary resources containing high chromium further generates a mass of hot metal containing high chromium (w(Cr)>10%). The chromium introduced into hot metal significantly lowers the activity coefficient of phosphorus in hot metal and competes for oxygen atoms with phosphorus, thus worsening the thermodynamic conditions of dephosphorization. Moreover, the chromium in hot metal is oxidized and migrated into slag, increasing the viscosity of slag and deteriorating the kinetics conditions for dephosphorization. For these reasons, the removal of harmful element phosphorus from hot metal containing chromium turns to be particularly difficult. This restricts the production of hot metal containing chromium and limits the utilization of low-grade chromium-containing ore and the returning material during the production of stainless steel. To provide more in-depth understanding and novel ideas concerning the dephosphorization of hot metal containing chromium to metallurgical workers, the studies on the dephosphorization of hot metal containing chromium were summarized, and the new research progress (such as the dephosphorization of hot metal containing moderate chro-mium, the detoxification and slag forming of dephosphorization slag) was focused on in this paper. Finally, the deficiencies in the research were pointed out and the research directions in the future were set.
