H08A漏钢原因分析及预防措施

Reasons Analysis and Countermeasures of Breakout in H08A Smelting Process

针对2#连铸机H08A钢频繁漏钢的现况,对H08A钢漏钢事故进行分析。认为H08A漏钢的主要原因是结晶器倒锥度小、通钢量大、结晶器水流量过大和足辊水量小。制定相应的改进措施,实施后,漏钢率得到了有效控制。

In view of H08A steel breakout accidents occurred on No. 2 continuous caster, this paper analyzs the main factors ：smaller taper control mould,high throughputs, larger rate of flow and smaller water ratio for foot roller and so on.. After improving measures are worked out and implemented, the breakout accidents has been effectively controlled.
