为将周期轧管机组生产套管的轧制工艺修订更符合ГОСТ632-80(A)的要求,苏联管材科研所与几家钢管厂共同就周期轧管机和定径机的变形参数对钢管几何尺寸精度和1m钢管重量的影响进行了研究。在下列几家钢管厂的轧管机上轧制了不同尺寸的Д和Е强度级薄壁管:在塔干罗格
In order to meet the requirements of ГОСТ632-80 (A), the revision of the rolling process of casing production of periodic pipe mill meets the requirements of ГОСТ632-80 (A). The Soviet Union Pipe Research Institute and several pipe mills jointly discussed the deformation parameters of the periodic rolling mill and sizing mill. Dimensional accuracy and 1m pipe weight were studied. Д and Е-strength thin-walled tubes of different sizes were rolled on the tube rolling mill at the following steelworks:
