复包球化处理工艺是我们最近试验的一种简单易行而又效果较好的球化处理工艺。所谓复包,是指在普通铁水包内,安设形状似小包的球化反应室,像大包与小包复合在一起的一种铁水包。这种铁水包既可以作球化处理包,也可以作球化处理后的浇包。复包的结构和尺寸如图9所示。形状象小铁水包的球化反应室构筑于大包的一侧,小包的活动包壁由石英砂和耐火泥打结而成,其壁厚为50～70毫米,中间嵌有由φ10钢筋焊成的骨架,外表敷有一层厚度约10～20毫米的石墨粉和耐火泥的混合料。打结好的小
Compound ball treatment process is our recent test of a simple and effective balling process better. The so-called complex bag, refers to the ordinary iron ladle, the shape of the shape of the packet to install the ball reaction chamber, like a bag and parcel together with a ladle. This ladle can be used for both pelletizing and pelletizing ladles. Complex structure and size shown in Figure 9. Shaped like a small iron ladle ball reaction chamber built on the side of the big package, packet activity package wall made of quartz sand and refractory mud knot formed, the wall thickness of 50 to 70 mm, the middle embedded by the φ10 steel welding Into the skeleton, the appearance of a layer of coated with a thickness of about 10 to 20 millimeters of graphite powder and refractory mixture of mud. Knot good small
