JACT News. -1991,10. -28～33 日本三菱公司三原制作所最近开发了一种新的球化处理方法。它是在冲入法的基础上加上一个具有连续通气孔的耐热三维过滤网作为包盖,并在浇包内部加一道隔墙,把浇包分为接受侧和球化侧两部分。这样在球化处理时发生的大量氧化镁白烟都被过滤网捕捉而不排到空气中,同时强烈的镁光及铁液飞溅现象也大为减少,包盖重量大大减轻,使作业环境条件及安全性得到了大幅度改善。
JACT News. -1991,10. -28 ~ 33 Japan’s Mitsubishi Sanyo has recently developed a new ball treatment method. It is based on the law into the law with a continuous ventilation holes heat-resistant three-dimensional filter cover, and add a wall inside the ladle, the ladle is divided into the receiving side and the ball-side two parts. So that a large number of magnesia-white smoke generated during the spheroidization process are captured by the filter but not discharged into the air. At the same time, the phenomenon of strong magnesium light and molten iron spatter is also greatly reduced, the cover weight is greatly reduced, and the operating environmental conditions and Safety has been greatly improved.
