摘要
针对宝钢钢管事业部Φ140mm连轧管机组改造后,初期设计的Meer材质顶头出现使用寿命低的情况,试制了一种新材质顶头,并从顶头形状、铸造工艺、氧化工艺等方面进行改进。通过试验,分析了这些改进措施对顶头使用寿命的影响。结果表明,新材质穿孔顶头的使用寿命较Meer材质顶头的提高7倍以上,解决了Φ140mm连轧管机组顶头消耗量过大的难题。
Addressing the post-modification problem of the Baosteel Φ140 mm MPM plant,i.e.,rather low service life of the piercing plug that was in a material as originally designed by Meer GmbH,Germany,the plug material is changed with a new one,and improvements on the plug proper are carried out,involving the profile of and casting and oxidation processes for the plug.Thanks to relevant tests,effects by these corrective actions on the plug service span are analyzed.The operation result of the modified plug made of the new material shows that its service life is 7 times over that of the plug in Meer material,which leads to solution of the mill＇ s big problem of unreasonably high plug consumption.
