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. This process is carried out, although the pig iron into steel, but steel liquid O content increased. O in molten steel generally [FeO] form. Without removing the residual excess oxygen in the steel, you can not cast into billets qualified, not good mechanical properties of steel. To do this, we need to add some more oxygen than iron binding capacity Wanted silicon barium calcium inoculant, and its easy to exclude from the oxide into the molten steel slag elemental silicon barium calcium inoculant to molten steel O removed, this a process called deoxy. Ferroalloy production technology development trend: Over the past twenty years, with the progress and development of the steel industry and science and technology, industrial production variety world ferroalloy smelting process, technology and equipment, energy saving, environmental protection, energy and resource recovery We have a rapid development and comprehensive utilization of breakthrough technologies.
