Either steelmaking method, you need to remove oxygen in the bath C, Si, Mn, P and other impurities, the end of the oxidation refining, steel liquid reaches a certain composition and temperature. If the steel is not oxygen, the embryo will not get the correct casting solidification structure. High oxygen content in steel Deoxidants price, but also produce skin bubbles, porosity and other defects, and exacerbate the harmful effects of sulfur. But also generate excessive oxide impurities, reduce the mechanical properties of steel ductility, impact toughness. Therefore, we must in the casting process of steel or aluminum calcium Deoxidants, plus Deoxidizer appropriate to reduce the liquid steel oxygen steelmaking deoxidizer, remove excess oxygen steel. The role of oxidative slag in the steelmaking process: the impact speed of slag and slag viscosity. FeO slag lime dissolve promote and accelerate slag, steel reaction kinetic conditions improve and accelerate the mass transfer process; slag Fe2O3 and alkaline oxide reacts ferrite, lower the slag melting point and viscosity, avoid steelmaking slag "back to dry." Effect of slag bath transfer to oxygen, the oxygen content of the molten steel dephosphorization. Carbon steel slag oxygen oxidation was significantly affected when the same steel carbon content, slag oxidation resistance, the high oxygen content of molten steel, and is conducive to dephosphorization. Effect of alloy and metal yield and lining life. Slag oxidation, the stronger, the lower the alloy and metal yield; slag oxidation resistance, lower lining life.
