连铸开浇塞棒未打开钢水自来的原因分析及控制措施

Analysis and Countermeasure of Molten Steel Uninvited Pouring When Stopper Was Unopened before Casting

通过对塞棒中间包开浇塞棒未打开钢水自来的原因进行分析并查找原因，制定塞棒中间包未开浇钢水自来的防范措施并在生产中进行实践，有效地控制了塞棒中间包未开浇钢水自来，保障品种钢的生产塞棒中间包开浇操作稳定、顺行。

By analyzing and searching causes of molten steel uninvited pouring when stopper was un- opened before continuous casting, we made countermeasures and put them into practice, effectively prevented the molten steel uninvited pouring, and ensured casting-start operation steady and smooth when we produced high quality steels.
