摘要
简要介绍了涂组顶头的机理及试用情况。试用结果表明,涂组顶头使用寿命远高于常规顶头,对于合金钢管的生产更具优越性,少量顶头已达到每只穿管600～800支的水平,
The mechanism and probation of alloy-coated assembly plugs are briefed. The results show that the plugs have many advantages in alloy steel tube production with their service life longer than that of traditional plugs and some of them are capable of piercing 600-800 pipes.
