Ferroalloys purposes: as a deoxidizer. Blowing oxygen steelmaking process is a method or adding an oxidizing agent to make molten iron and phosphorus removal process decarbonization, sulfur and other harmful impurities. Silicon barium calcium inoculant conduct this process, although pig iron into steel silicon barium calcium inoculant price, but liquid steel O content increased. O in molten steel generally [FeO] form. If you do not remain in the steel oxygen to remove excess silicon barium calcium inoculant plant, it can not cast into billets qualified silicon barium calcium inoculant offer, not a good mechanical properties of steel. To do this, we need to add some combines with oxygen stronger than iron, and its easy to rule out the oxide into the slag from molten steel elements, the liquid steel O removed, this process is called deoxygenation. Ferroalloys purposes: as an alloying agent. Alloy steels it contains different alloying elements have different properties. The content of alloying elements in steel alloy by adding methods to adjust. Ferroalloy is used to adjust the content of alloying elements in steel alloying agent called. The alloying agents are commonly used silicon, manganese, chromium, molybdenum, vanadium, tungsten, titanium, cobalt, nickel, boron, niobium, zirconium alloy.
