Barium calcium silicon alloy is a new offer from one or two or more metals or non-metallic elements consisting of iron and alloy steel and as a deoxidizer, desulfurizer and alloy additives such as foundry industry. For example Ferrosilicon is an alloy of silicon and iron; ferromanganese alloy of manganese and iron; calcium alloy is an alloy consisting of silicon and calcium. On production methods and purposes in terms of the price of new silicon barium, calcium, iron alloy also includes low alloy metal manganese, chromium, vanadium and industrial silicon. 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. Conduct quality new silicon barium calcium in this process, although pig iron into steel, but steel liquid O content increased. O in molten steel generally [FeO] form. If you do not remain in the steel to remove excess oxygen new silicon barium calcium can not be cast into billets qualified, not 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.
