第十一个五年计划国民经济最主要的任务之一乃是用提高其质量的方法来扩大轧件的合格率。在某些冶金企业中按表面缺陷,10TP 和20TP 钢的废管坯的损耗还是很大的。在西西伯利亚钢铁公司里,坯料最突出的表面缺陷就是结疤、纵向裂纹和龟裂,它们在很大程度上与钢的脱氧和浇铸的工艺有关。为了测定按这些缺陷降低金属损耗的可能性,在西西伯利亚钢铁公司(3CMK)№1转炉车间里
Eleventh five-year plan one of the most important tasks of the national economy is to improve the quality of the method to increase the pass rate of rolling. In some metallurgical enterprises by surface defects, 10TP and 20TP steel waste tube billet loss is still great. In West Siberian Steel, the most prominent surface defects of blanks are scarring, longitudinal cracks and cracks, which are largely due to the deoxidation and casting of steel. In order to determine the possibility of reducing metal losses according to these defects, in the West Siberian Iron and Steel Company (3CMK) № 1 converter workshop
