一、前言我国从苏联进口的若干台冷轧管机中,有ХПТ—75、ХПТ—55、ХПТ—32型三种,其中多数是后两种,它们分别安装在全国几个主要钢管厂和有色金属管厂。我厂的两台ХПТ—55—1和一台ХПТ—32—1型冷轧管机是首批安装的。但是,在安装初期试运转时,这三台冷轧管机经过多方调试,连空车都开不起来,还损坏了设备。这三台冷轧管机是生产高、精、尖产品的关键设备,它们不能运转,生产就无法进行。面对这种情况,我们经过反复试验和细心观察,终于找到了不能运转的原
I. Introduction Several cold-rolled pipe mills imported from the Soviet Union in our country have three types of ХПТ-75, ХПТ-55 and ХПТ-32, most of which are the latter two, which are respectively installed in several major steel pipe mills in the country and Non-ferrous metal pipe plant. Our two ХПТ-55-1 and a ХПТ-32-1 cold rolling mill are the first to be installed. However, during the initial installation and commissioning, the three cold-rolling mills were debugged in multiple ways, and even the empty ones could not open and damaged the equipment. These three cold rolling mills are the key equipment for producing high, refined and sharp products that can not be run and can not be produced. Faced with this situation, after repeated trial and careful observation, we finally found the original
