K·李卜克内西厂第四轧管车间的热处理工段(如图1) 是供生产Φ141～351亳米,壁厚7～25亳米的钢管用的。该工段的设计根据全苏管材研究所提出的要求,由乌克兰冶金设计院完成。考虑到要求处理的管子规格范围很宽,加之其中还包括过去在工业流水线上从未热处理过的大口径钢管,因此,要求扩大热处理机组工艺上的适应性。该热处理工段的 K · Liebknecht plant fourth rolling workshop heat treatment section (Figure 1) for the production of Φ141 ~ 351 millimeters, the wall thickness of 7-25 millimeters of steel used. The design of this section is based on the request of All-Si Tubing Research Institute and completed by Ukraine Metallurgical Design Institute. Considering the wide range of pipe sizes required and the large caliber pipes that have historically not been heat treated on industrial lines, there is a need to expand the process adaptability of heat treatment units. The heat treatment section
