ＫＴＢ法在世界各公司的应用效果和发展［日］江原猛等１绪言随着用户对冷轧钢板机械特性要求的提高，稳定地大量冶炼极低碳钢的必要性增大了，原来在真空脱气设备中，仅以未脱氧钢中的含氧量来真空脱碳的极低碳钢冶炼方法，带来表１中所列的１３问题，存在①⑧所示的对炼... Effect and Development of KTB Laws in Companies around the World 1, Japan, Japan, Japan, Japan, Japan Introduction INTRODUCTION With the increasing demands on the mechanical properties of cold-rolled steel sheets, the need for stable and large-scale smelting of very low carbon steel has increased. Degassing equipment, only the oxygen content of non-deoxidized steel to decarburization of the vacuum decarburization of ultra-low carbon steel smelting method, bringing the problems listed in Table 1 13, there ①⑧ shown on the refining ...
