Ferroalloy production methods: oxygen converter method. The main production of carbon ferrochrome and carbon ferromanganese. The liquid carbon ferrochrome (or carbon ferromanganese) blended with the converter, oxygen lance to bath decarburization. The most widely used at home and abroad is a top blowing and bottom blowing two ways. Silicon alloy silicon alloy mainly ferrosilicon, industrial silicon and silicon-deoxy agent. Ferroalloys purposes: as a deoxidizer. Steelmaking is a method of removing iron oxide liquid carbon, phosphorus and other impurities. Upon completion of these tasks Hou Jilin oxidation steelmaking slag agent, while also absorbing liquid steel oxygen steelmaking slag Hubei agent, if the presence of oxygen will greatly reduce the performance of the steel in the steel. So we need to add some bound with oxygen relatively strong, and its oxidation products can be successfully excluded from liquid steel, so that the oxygen content in molten steel to reduce elements.
