一、133张减机组概况张力减径是钢_管生产中的新技术,它不仅可以扩大原机组的产品范围,而且还可以提高产量,改善质量,成倍增加经济收益。目前,全世界共有200多台各种型式的张力减径机在各种无缝与直缝焊管机组中工作。我国早在六十年代就对张减的研究与应用给予很大的关注。1968年,长城钢厂从西德引进一套当时是先进水平的133张减机组。这个机组1975年完成安装并进行试轧,随后又试生产多次。
First, the overview of 133 reduction units Tension reduction is a new technology in steel production, which can not only expand the product range of the original unit, but also increase output, improve quality and multiply economic benefits. At present, there are more than 200 various types of tension reducing machines in the world that work in various seamless and straight seam welded pipe units. As early as the 1960s, our country paid much attention to the research and application of Zhangzhang. In 1968, the Great Wall Steel Mill imported a set of 133 reduction units from the West Germany at the advanced level at that time. The unit was installed and commissioned in 1975 and then piloted several times.
