本发明涉及双渣法冶炼工艺，属于转炉炼钢技术领域，解决了现有冶炼工艺脱磷效果差、渣料消耗高、炉渣不易倒出、冶炼周期长、钢水过氧化的问题。双渣法冶炼工艺具体包括铁水脱磷、脱磷渣排出、少渣高强度供氧脱碳炼钢；铁水脱磷包括顶底复合吹氧快速脱硅脱锰，顶吹氧气、底吹惰性气体脱磷；脱磷渣排出包括泡沫化脱磷渣控渣、泡沫化脱磷渣压渣和泡沫化脱磷渣吹扫；少渣高强度供氧脱碳炼钢包括高强度顶底复合吹氧脱碳炼钢、低强度顶底复合吹氧拉碳出钢和底吹惰性气体出钢。本发明实现了顶吹氧气与底吹氧气、惰性气体的供气技术的优化组合，实现了顶部添加块状渣料与底吹粉剂的渣料技术的合理搭配，可以实现高效脱磷、低渣料消耗、少渣高效冶炼。

The invention relates to double slag smelting process, which belongs to the field of converter steelmaking, solving the existing problems:defective effect of smelting process, high consumption of the slag, the slag is not easy to fall out, the smelting cycle is long, and the steel water is oxidized. Double slag smelting process specifically includes ferrous dephosphorus, deprofunction, eliminate high strength oxygen release steel. Iron water dephosphorization includes the top composite blow oxygen rapid debron de-manganese, top blow oxygen, bottom inert gas dephosphoru. Definched residue exclusion includes foaminated dephosol residue, foamized defective depoft segments and foamine defective hair sweep. Less slag high strength oxygen removal steel includes high strength top composite brake oxygen removal steel, low strength top composite blower pull-up steel and bottom-blowing gas out steel. The invention achieves an optimized combination of top blowout and air supply technology of the bottom blowing oxygen, an inert gas, and realizes the reasonable matching of the residue technique of the top addition of a slag slag and the bottom flushing powder, which can achieve high-efficiency dephosphorus, low slag consumption, and less residue high-efficiency smelting.
