球化处理工艺,目前国内有铁水冲入法、合金坨压入法,压力加镁法等。从1980年开始,国外有些工厂先后采用盖包处理法,因有其独特优点,国外采用此方法进行球化处理的工厂愈来愈多,被处理铁水重量最少80公斤,最多已达9吨,其结构也有所发展。盖包处理法,盖和包之间没有固定连接结构。球化处理过程中,靠盖本身的自重压住包。被处理铁水从盖上的漏槽注入,经过注孔与包中 Spheroidization process, the current domestic molten iron into the law, alloy lump pressure method, the pressure plus magnesium method. Since 1980, some foreign factories have adopted the lid treatment method, because of its unique advantages, foreign countries using this method of ball processing plant more and more, the weight of at least 80 kg of hot metal being processed, up to 9 tons, Its structure has also evolved. Lid treatment method, there is no fixed connection between the lid and the package structure. Spheroidization process, by the weight of the cover itself pressed the bag. The molten iron to be treated is injected from the drain groove in the cap through the injection hole and the bag
