一、顶管机组概述顶管机组是热轧无缝钢管生产中比较简便的一种设备。顶管机组和其它轧管机组一样,都是将加热的实心坯穿孔成空心坯,然后将热的空心坯轧制成无缝钢管。各轧管机组在轧制时,采用不同的轧管机,一般采用什么轧管机,则整套生产设备就叫什么机组。用顶管机组制无缝钢管的整套生产设备,就叫顶管机组。用顶管机组生产无缝钢管的方法是比较古老的一种轧管方法。这种方法具有许多优点,它吸引了世界各国投资建设者的兴趣。因此,它经过漫长的历史考验,不 First, the top pipe unit overview Top pipe unit is a relatively simple production of hot-rolled seamless steel pipe equipment. Pipe jacking units, like other pipe rolling units, are perforated with heated solid billet into a hollow billet, which is then rolled into a seamless steel tube. The rolling mill units in the rolling, the use of different pipe rolling machine, generally what pipe rolling machine, the whole production equipment is called what unit. With pipe jacking unit of seamless steel pipe production equipment, called jacking unit. Pipe jacking unit with the production of seamless steel pipe method is a more ancient method of rolling pipe. This approach has many advantages, which attract the interest of investment builders all over the world. So it goes through a lengthy historical test, no
