摘　　要：结合邯钢CSP生产实践,对CSP连铸机漏钢原因进行了分析并提出了预防措施。生产实践表明,通过加强中间包及结晶器的准备工作,提高开浇操作水平,可有效减少开浇漏钢。通过优化钢水成分,提高钢水纯净度,优化保护渣性能,加强结晶器铜板表面质量的检查,提高格栅表面质量,提高水口材质,保持结晶器合适的锥度,控制结晶器热流比及拉速,可有效减少浇注过程中的漏钢事故。Through the causes analysis put forward prevent measures for breakout of Handan CSP caster. The practice indicated that according to strengthening preparation work and improving operating altitude of initiation of casting, the initiation of casting breakout can be reduced effectively. According to optimizing steel composition, improving steel cleanliness, optimzing mould powder performance, strengthening the check of mould copper surface quality, improving quality of grid and nozzle, keeping mould taper, controlling suitable heat flux rate and casting speed, the breakout in casting can be reduced effectively.
