转炉是炼钢主要设备,按吹炼工艺有顶吹转炉、底吹转炉和顶底复合吹炼转炉等。转炉炼钢主要是将铁水中的硅、锰、磷、硫、碳等杂质氧化,使其进入废气、炉渣并排除,从而得到成分及温度合格的钢水。炼钢时先将废钢装入炉内,兑入铁水(两者均为主原料),再加入第二批造渣料(主要是石灰,为副原料),然后下降水冷氧枪(吹氧用),氧气经氧枪头部的超音速喷嘴向下吹入熔池,氧化硅、锰、碳等元素并放出热量供冶炼之用。造渣的目的是将硅、锰、磷、
Converter is the main equipment of steelmaking, according to the blowing process top-blown converter, bottom blown converter and top and bottom composite blowing converter. Converter steel is mainly the molten iron in silicon, manganese, phosphorus, sulfur, carbon and other impurities oxidation, so that it enters the exhaust gas, slag and exclusion, resulting in the composition and temperature of qualified molten steel. When making steel, first load the scrap into the furnace and mix it into the hot metal (both of which are the main raw materials), then add the second batch of slag making materials (mainly lime as an auxiliary material), then lower the water cooled oxygen lance ), The oxygen is blown down into the molten pool through the supersonic nozzle of the oxygen gun head, silicon oxide, manganese, carbon and other elements and emit heat for smelting purposes. The purpose of slagging is silicon, manganese, phosphorus,
