    DOMESTIC TUBE MAKERS NEED TO SELECT STRETCH REDUCING MILL PROCESS AND EQUIPMENT APPROPRIATELY

    • 摘要: 針對國內(nèi)一些地方企業(yè)應(yīng)用張力減徑工藝和設(shè)備存在的偏差，指出應(yīng)正確選用張力減徑工藝，不能把經(jīng)過張力減徑的焊管稱為無縫鋼管。張力減徑設(shè)備從設(shè)計到制造都有嚴(yán)格的要求，若選用不當(dāng)，則達不到減徑功能，難以生產(chǎn)出合格的產(chǎn)品。

       

      Abstract: Based on the fact that some local tube makers are using stretch-reducing process and equipment inappropriately,the author points out that correct selection of stretch-reducing process technology has to be made and that none of the welded tubes stretch-reduced can be considered as seamless steel tube. Stringent criteria has been set up for all the aspects of the stretchreducing mill equipment from design to manufacture. Inappropriate equipment selection would hardly meet tube reducing purpose to turn out qualified products.
