复包球化处理工艺是一种简单易行,效果良好的球化处理工艺。所谓“复包”,是指在普通铁水包内,安设形状象小包的潘动包壁,犹如大包与小包复合而成,见图1。它既可作球化处理包,也可以作球化处理后的浇包。这种工艺有较强的适应性,无论是国内现有的冲天炉或其他熔炉,都能适用,它不需要增添新的设备,操作简便,便于推广。一、复包的结构和操作工艺图2为1.6～1.8吨复包的结构简图。构筑在大包一侧的小包是球化反应室,其活动包壁可用成型耐火砖或用石英砂与耐火泥打结而成。其固定方式如图 Compound ball treatment process is a simple, good effect of the ball treatment process. The so-called “complex” refers to the ordinary iron ladle, the shape of a small package like the installation of Pan moving wall, like a bag and packet composite, shown in Figure 1. It can be used for balling treatment package, can also be used for pelletized ladle. This process has strong adaptability, whether it is the existing cupola or other furnace, can apply, it does not need to add new equipment, easy to operate, easy to promote. First, the complex structure and operation process Figure 2 is 1.6 ~ 1.8 tons complex structure diagram. Built on one side of the parcel is the ball of the ball reaction chamber, the active cladding can be used to form refractory brick or quartz sand and refractory mud knot formed. The fixed way as shown
