摘　　要：在25t转炉上试验采用AlMnTiFe合金做为Q235B钢的终脱氧剂,与SiAlCa合金进行对比。结果表明,AlMnTiFe复合脱氧合金能有效降低钢水全氧含量,提高钢水质量;采用AlMnTiFe脱氧后,钢水浇注良好,铸坯内部组织致密,钢材力学性能优良;AlMnTiFe合金代替SiAlCa合金进行终脱氧,可降低吨钢脱氧成本0.84元。AlMnTiFe alloy was experimented on the 25t BOF as the final deoxidation of Q235 steel.By contrast to SiAlCa alloy, the result has shown that the AlMnTiFe alloy can reduce the fully oxygen content of liquid steel effectively and improve the quality of liquid steel; the quality of slab, the castability of liquid steel. The inner structure and the strength property of final products are also bettered efficiently Above all, the cost of final deoxidation per ton of steel can be reduced by 084 Yuan
