摘要
介绍了用76mm穿孔机组生产63mm毛管的设备概况及其改进。改进后,76mm穿孔机组增加了产品范围,为后面的冷拔工序减少了拉拔道次,从而降低了51mm以下冷拔管的生产成本。
In this paper the general situation and the improvement of the main equipments of76piercing mills using for63shell are introduced.By improvement,the products scope is exp anded,the drawing pass decreased in latter cold-drawn process,thus the produc tion cost of the cold-drawn shell which diameter is below51is reduced.
