In the case of semi-killed or balanced steel, more deoxidation is carried out than with rimming steel, but not enough to completely "kill" the steel. 半镇静钢比沸腾钢脱的氧多,但又不至于使钢完全“镇静”。
I suppose semi-killed steel must be just between these two in every aspects. 木材两端厚度各切一半我想半镇静钢可能在各方面都介于这两者之间吧?
What do the terms "rimming steel"," fully killed steel "and" semi-killed steel "refer to? 这3个术语“沸腾钢”、“镇静钢”、“半镇静钢”指的是什么?
Oxygen activity determination and control in free cutting semi-killed steel 半镇静易切削钢中氧活度的测定与控制
This paper describes the method of production of semi-killed steel in Wuhan Iron and Steel Company, the grades made, and the results of using them. 本文概述了武汉钢铁公司半镇静钢生产的品种、工艺、质量及使用效果。
Comparison tests were carried out to determine the surface and interior quality of semi-killed steel, and it was found that the "porosity" that the appeared on the cross section of the bloom could be left uncut, so that the metal yield could be increased. 对半镇静钢的表面和内部质量,进行了生产对比试验,认为因疏松引起的钢坯断面空洞,可以少切或不切,以便合理提高钢坯收得率。
