摘要
本文介绍了大方坯弹簧钢经转炉冶炼、LF+RH精炼、连铸、二火修磨的技术方案及试验结果。生产实践表明,铸坯表面质量良好,成分偏析可控制在0.97-1.04,中心疏松和中心偏析均≤1.0级,武钢采用大方坯连铸工艺生产55SiCr弹簧钢取得明显效果。
This paper introduces technical scheme and test results on bloom continuous casting of spring steel from converter smelting,LF+RH refining,continuous casting and two fire grinding.The production practice shows than the surface quality is good,the segregation of composition fate cab be controlled at 0.96-1.03,The spring steel 55 SiCr produced by the bloom continuous casting process has obvious effect.
