一、连轧管机组发展简史及其主要优缺点连续式轧管机组(以下简称连轧管机组)是目前世界上生产小直径无缝钢管效率高,质量好,产品范围大,自动化程度高的生产设备。远在一个世纪以前,世界上有些国家的钢厂就致力于研究在二辊式多机架轧机上生产无缝钢管。1843年世界上发明了第一台两个机架组成的连轧管机,用以轧制铸造管坯。继之在1882年,法国洛林—艾斯库公司诺尔厂建了一台试验用的连轧管机,1904年法塞尔采用浮动芯棒在多机架轧机上制造无 First, a brief history of the development of continuous rolling mill unit and its main advantages and disadvantages Continuous rolling mill unit (hereinafter referred to as the continuous rolling mill unit) is the world production of small diameter seamless steel pipe with high efficiency, good quality, large product range, high degree of automation Production equipment. A century ago, mills in some countries of the world were devoted to studying the production of seamless steel tubes on two-roller multi-stand mills. In 1843, the world first invented the first two-stand stand-alone tube mill for the casting of cast tubes. Followed in 1882, the French Lorraine - Aaseku Nuoer plant to build a test of the rolling mill, 1904 Fassel float core mandrel in the manufacture of multi-stand mill
