据日本“材料”,1990,3:1180报道为适应厚板优质化和超低碳钢产量的不断增加,要求高精度的RH处理,但是,传统的RH设备一直存在着由于真空室内壁粘附残钢,而导致脱气处理能力降低和钢液增碳等问题。本次开发的是将富氧烧咀应用于在线操作,对清除真空室内壁的残钢取得了显著的效果。就其效果叙述如下。 According to the Japanese “Materials”, 1990,3: 1180 reported to meet the high quality and ultra-low-carbon steel plate production continued to increase, requiring high-precision RH treatment, but the traditional RH equipment has been the existence of vacuum chamber adhesion Residual steel, which led to lower degassing capacity and carbon steel and other issues. The development is the application of oxygen-rich burned Tsui online operation, to remove the inner wall of the vacuum chamber of residual steel has achieved remarkable results. The effect is described below.
