摘要 为了研究SWRH82B硬线钢通过控制精炼渣的组成实现夹杂物塑性化的可行性,通过对炼钢过程中各工序的精炼渣和钢液进行取样,并对精炼渣成分、钢液总氧含量以及夹杂物的形貌、尺寸、成分等进行检测分析。结果表明,采用无铝化脱氧,并将精炼渣的碱度控制在0.8-1.2,Al2O3质量分数控制在10%以下时,能使CaO-Al2O3-SiO2系夹杂物成为塑性夹杂物;钢水经过RH真空精炼后夹杂物尺寸变大,并且夹杂物的Al2O3质量分数降低,SiO2质量分数升高,通过相关检测分析了造成此现象的原因,并提出了改进措施。 In order to study the feasibility of the implementation of the plasticization of inclusions in SWRH82 Bhard wire steel through the control of the composition of refining slag,the refining slag and molten steel were sampled during the steelmaking process,and the composition of the refining slag,the total oxygen content of the liquid steel and the shape,size and composition of the inclusion were examined and analyzed.The result showed when the refining slag basicity was controlled at 0.8-1.2 and the mass fraction of Al2O3 was controlled less than 10%,the CaO-Al2O3-SiO2 system inclusions were transformed into plastic inclusions.However,after RH treatment,the inclusion size became large,the Al2O3 mass fraction of inclusions decreased and the SiO2 mass fraction increased.The reasons for this phenomenon were discussed and the corresponding improvement measures were proposed.
