用气体渗硅法制造６．５％Ｓｉ钢板气体渗硅法制造６．５％Ｓｉ钢板，是在高温下使可轧制的低硅钢板与气态ＳｉＣｌ４起反应，而使Ｓｉ渗入钢板内来生产高硅钢的方法。但此法有使硅钢板在表面层附近形成气孔缺陷的问题，这是因为Ｓｉ从钢板表面往内部渗透时Ｆｅ与Ｓｉ的扩... Gas-infiltrated 6.5% Si Steel Gas Infiltrating Process 6.5% Si steel sheet is produced by gas-infiltrating a silicon-based gas that is capable of reacting with a low-silicon steel sheet that can be rolled at high temperature with gaseous SiCl4 to infiltrate Si into the steel sheet High silicon steel method. However, this method has the problem that the silicon steel plate forms a pore defect in the vicinity of the surface layer because of the expansion of Fe and Si when Si permeates from the surface of the steel plate to the inside ...
