降低小方坯漏钢工艺研究

Study on how to decrease the billet caster's break - out rate

小方坯连铸机在包钢是新工艺、新设备,由于热试运行时间短又无相关工艺参数可借鉴等原因,初始阶段该铸机在生产中的漏钢率较高,一度曾达到1.5％。有关人员认真分析小方坯漏钢的原因及影响因素,在此基础上提出了降低漏钢率的措施,并在实际运行中取得了良好的效果。

The billet caster is a machine with a new technology. Owing to short time of hot commissioning and no related technology parameters as a reference, the breakout rate of the caster was high during the initial stage getting up to 1.5 % . Engineers in the Workshop analyzed its seasons and effecting factors, putting forward measures of decreasing break out rate and having got excellent results in operation.
