【摘要】 日钢在60t转炉上试验采用AlCaC作为Q235B钢的终脱氧剂,并与目前使用的SiAlTi脱氧合金进行了对比,结果表明,AlCaC复合脱氧剂能有效降低钢中全氧含量,提高钢水质量,钢水浇注良好,铸坯内部组织致密,钢材力学性能优良,并且吨钢降低脱氧成本0.60元。更多还原

【Abstract】 Rizhao Steel experimented in 60 t converter using AlCaC as final deoxidizer of Q235B steel and compared with using SiAlTi deoxidizing alloy. The results showed that AlCaC compound deoxidizer reduced the entire oxygen content in the steel, improved the molten steel quality and decreased oxidizing cost 0.6 Yuan per ton steel, the molten steel casting is good, the casting blank had compact microstructure and the mechanical properties of the steel products were fine.更多还原
