| 摘 要： | 针对攀钢IF钢RH处理过程终点碳含量偏高及不稳定的问题,对IF钢生产工艺过程进行了跟踪调查.结果表明:RH处理前钢水C]及aO]、真空度、脱碳时间、钢包耐火材料及合金增碳等是影响IF钢碳含量偏高及不稳定的主要因素.RH进站C]含量高于0.045%,终点碳含量与进站碳含量成正比关系;最小真空度越低,脱碳时间越长,终点碳含量就越低.为保证攀钢IF钢碳含量合格,应将RH进站钢水碳含量控制在0.030%～0.045%、aO]控制在(500～700)×10-6,加强设备监控与维护以维持足够的深真空时间和进一步降低真空度.为减少RH处理后期钢液增碳,在保证真空室不结冷钢的前提下应使用渣线部位不含碳的钢包及低碳合金. |
