    焊管軋輥的孔型與磨損

    GROOVE AND GROOVE WEARING OF WELDEDPPE MILL ROLL

    • 摘要: 分析了焊管生產(chǎn)時(shí)軋制區(qū)帶鋼在初始開(kāi)口孔型中的變形行為及孔型磨損情況,指出采用W孔型作初始變形平輥,可有效地改善帶鋼受力狀態(tài),減輕磨損。

       

      Abstract: An investigation is made on the deformation of the strip under the initial opening groove and groove wearing during the rolling course of welded pipe production.It is concluded that the loading conditions of the material could be improved to reduce the wear degree of the groove by means of plain roll with W shaped groove for initial deformation purpose.
