7号方坯连铸机高效生产实践

Efficient Production Practice of No.7 Billet Caster

分析了7号方坯连铸机高效生产中存在的问题,介绍实施的提高拉速、事故控制与预防、提高作业率、辊道热送等措施,在确保安全可靠、生产顺行、质量稳定的前提下,连铸机总拉速从16-17 m/min提高到19-20 m/min,作业率从从87%提高到93%,辊道热送率从40%提高到70%。

The problems existing in the efficient production of No.7 Billet Caster were analyzed, the countermeasures such as to improve the casting speed,control and prevent the accidents,improve the work rate and implement the roller table hot charging were introduced,and hence,the total casting speed of the caster was enhanced from 16-17 m/min to 19-20 m/min, the work rate was increased from 87% to 93%,and the roller table hot charging rate was also increased from 40% to 70% in the premise of ensuring safety,smooth production and stable quality.
