连铸机拉矫辊使用期短,更换量大是生产线亟待解决的课题之一。本文针对武钢引进的“西马克”弧型连铸机的拉矫辊,进行了研究。阐述了辊子使用寿命短的主要原因,并提出了用自动堆焊制造复合拉矫辊来取代原整体锻造辊的全套工艺。经实际应用证明:新研制的堆焊复合拉矫辊较原整体锻造辊的使用寿命提高6倍以上
Caster straightening roller short service life, the replacement of large production line is one of the topics to be solved. In this paper, WISCO introduced the “West Mark” arc continuous casting machine straightening roller, were studied. The main reasons for the short service life of the roller are expounded and the whole process of replacing the original whole forging roller with automatic straightening and welding is proposed. The practical application of proof: the newly developed surfacing composite straightening roller than the original overall forging roller life of more than 6 times
