无缝钢管机组正在向大型化、连续化和高速化方向发展。近十年来,国外已很少建自动轧管机组,而长芯棒的顶管机组和传统的连轧管机发展较快,限动芯棒连轧管机发展更为迅速。为了改造我国的现有设备,必须引进一些新技术和新设备。应扩大无缝管坯的连铸比,以提高经济效益。 Seamless steel tube unit is large-scale, continuous and high-speed direction. In recent ten years, foreign countries have seldom built automatic pipe rolling units, while the long mandrel pipe jacking units and the traditional continuous rolling pipe machine developed rapidly, limited mandrel rolling mill machine developed more rapidly. In order to transform the existing equipment in our country, we must introduce some new technologies and new equipment. Should be expanded seamless tube continuous casting ratio, in order to improve economic efficiency.
