摘要: 近40年連軋管機(jī)組得到大力發(fā)展,設(shè)備年生產(chǎn)能力已達(dá)2 000萬(wàn)t。介紹了連軋管機(jī)組的應(yīng)用范圍及特點(diǎn)、發(fā)展歷程及生產(chǎn)技術(shù)的發(fā)展情況;主要介紹了錐形輥穿孔機(jī)、三輥連軋管機(jī)、張力減徑機(jī)在質(zhì)量控制技術(shù)等方面的新工藝,探討了連軋管機(jī)組進(jìn)一步發(fā)展的方向。Abstract: Over the past four decades,the mandrel pipe mill has been developed so fast that the total annual capacity of such mills is up to 20 million tons. Elaborated in the paper are the application scope and characteristics of the mandrel pipe mill,focusing on the newly-developed technologies for quality control of the cone-type piercing mill,the 3-roll continous rolling proper and the stretch reducing mill. Also discussed is the future development trend of this type of pipe-rolling mill.
