密封处理球墨铸铁,已在各厂试验和采用,但如设计时不考虑结构和强度关系,则在生产中容易造成爆炸事故。据1958年“铸工”第4期报导,许多单位反映因压力过大而使整个包子爆炸。现将结构和强度问题概述如下。一、密封罐结构的设计原则 (1)必须考虑操作方便。一般密封处理罐可先将盖子密封好后,铁水用漏斗漏入(或出铁槽伸进大口处流入),处理前将包子用压缩空气(或鼓风机)吹烧着的焦炭烘烤。我厂小型处理采用这种方法,认为较方便。
Sealed ductile iron, has been tested and adopted in various plants, but if the design does not consider the relationship between the structure and strength, it is easy to cause an explosion in the production. According to the 1958 Castor No.4 report, many units reported that the whole buns exploded due to excessive pressure. The structure and strength issues are summarized below. First, the design principle of sealed tank structure (1) must consider the ease of operation. General sealed tank can be sealed first cover, the molten iron leak into the funnel (or iron trough into the large mouth inflow), before the buns with compressed air (or blower) blowing the coke baking. I plant small processing using this method, that more convenient.
