摘　　要：天钢大圆坯连铸机在首次热试时采用原设计的引锭头连接件和工艺参数后发生开浇漏钢。为了防止开浇漏钢的发生影响生产,天钢炼钢厂经过对引锭头连接件、冷料结构和工艺参数的改进后,有效地解决了开浇漏钢的问题,未再发生开浇漏钢事故。Breakout took place when the originally designed dummy bar head connection and process parameters were adopted at the first hot commissioning of TISG Round Bloom Caster.In order to prevent the breakout from affecting the production,Steel-making Subsidiary improved dummy bar head connection,cold material structure and process parameters.As a result,the breakout at casting start was effectively solved and eliminated thoroughly.
