脱磷是炼钢过程中重要环节之一,传统的办法是用石灰造渣,通过氧化使磷进入渣中,以后将其扒除。但有些情况这种方法不宜采用,如合金钢的返回法冶炼,不能进行氧化和扒渣操作,即使部分扒渣也会损失贵重的合金元素,特别是像不锈钢,高锰钢等高合金钢经过多次返回重熔后,钢中的磷富集提高,使耐蚀或使用性能下降,严重时还会超过标准规定而报废,还有在还原期合金化时,遇到高磷铁合金或扒渣不干净的情况,回磷严重,使成份出格,不得不返工或报废。楚雄州吕合煤矿和昆明工学院共同发展了一种用钡系渣脱磷的新方法,不用扒除氧化渣,还 Dephosphorization is an important part of the steelmaking process. The traditional method is to make slag by using lime to make phosphorus enter the slag through oxidation and then remove it. However, in some cases this method is not suitable for use, such as the return of the alloy steel smelting, can not be oxidized and slag removal operation, even some of the slag will also lose valuable alloying elements, especially high alloy steel such as stainless steel, high manganese steel Repeated return to the remelting, the phosphorus enrichment in the steel to improve, so corrosion or use performance degradation, in serious cases will exceed the standard provisions of the scrap, as well as alloying in the reduction period, met the high phosphorus iron alloy or slag Not clean, serious back to phosphorus, make the ingredients out of style, had to rework or scrapped. Chuxiong Luhe Coal Mine and Kunming Institute of Technology jointly developed a new method of dephosphorization with barium-based slag, without removing the oxide residue, but also
