摘　　要：简述了Q195拉丝钢具有低碳、低硅、低锰的特性,钢水过氧化偏差大直接对合金收得率、钢水可浇性、钢水收得率、炉衬侵蚀、钢水中氧化夹杂物质量分数和生产事故等各方面的影响。炼钢厂对造成Q195钢过氧化现象的原因进行了探讨与分析,最终通过确保原材料质量、提高转炉一倒三命中率、优化脱氧工艺、落实钢包冶金、减少各类温降、优化生产组织、提高操作水平等方案,使Q195钢过氧化钢水得到有效控制,技术经济指标达到理想水平。Q195brushed steel has the properties of low C,low Si and low Mn.The big steel peroxidation deviation had directly influences on the alloy yield rate,molten steel pouring of molten steel yield rate and lining erosion,molten steel inclusion content and production accidents and other various aspects.The reasons for the peroxidation of Q195 steel were discussed and analyzed.Finally the peroxidation of Q195 steel was effectively controlled and technical and economic indicators were reached the desired level through ensuring raw material quality,improving the converter three hit rate and operation level,optimizing the deoxidization process and production organization and implementing the ladle metallurgy,reducing all kinds of temperature drop.
