一、引言行星斜轧钢管是七十代末期新发展起来的一种大形变的无缝管生产方法。目前除了西德Eschweiler Bergwerk—vevein公司安装三辊行星轧管机生产70～220mm钢管外,美国已在建设一套114～244.5mm机组,用连铸坯生产石油套管。事实表明,行星斜轧钢管工艺已经成为一种成熟的无缝管生产方法。行星斜轧管方法与现有的各种轧管方法相比其优点是:壁厚公差达到5％;钢管长度可达百米以上,延伸率可达15,一道次可以轧成成品,有利于实现控制轧制;能耗低,噪音小、投资少,因此
First, the introduction Planetary rolling steel pipe is the late seventies developed a new form of large deformation of seamless pipe production methods. In addition to the West Germany Eschweiler Bergwerk-vevein company installed three-roll planetary tube mill production 70 ~ 220mm pipe, the United States has been building a 114 ~ 244.5mm unit, the production of billet with an oil casing. The fact shows that the process of planets rolling steel pipe has become a mature method of seamless pipe production. Compared with the existing method of rolling tube, the method of planet inclined tube rolling has the following advantages: the wall thickness tolerance reaches 5%; the length of the steel tube can reach more than one hundred meters and the elongation rate can reach 15, which can be rolled into finished product in one pass, Achieve controlled rolling; low energy consumption, low noise, less investment, therefore
