摘要: 针对唐山国丰钢铁有限公司板坯连铸机频繁出现漏钢报警的问题,通过现场调研分析,分别从结晶器铜板、连铸保护渣优化、结晶器液面波动、拉速控制和结晶器水口更换等方面进行了系统地优化,优化之后使得两台铸机4个流次由原来每月平均报警26次降低到8次之内,明显的提高了板坯连铸机的生产效率。

Abstract: In order to resolve the breakout warning in slab continuous casting of Guofeng Steel, Mould copper plate, mold flux, liquid level fluctuation of mold flux, stabilizing casting speed and replacing of the submerged entry nozzle were analyzed and optimized by the field survey analysis. By these measures, the average warning number of the two continuous casting machines was reduced to 8 times from 26 times per mouth, which greatly improved the production efficiency of casting machine.

Key words: slab continuous casting, sticking breakout, breakout warning
