南京汽車制造厂鑄工車間技术人員和澆注组、喷砂组的工人们合作,先后試驗成功了土法压力加镁和新球化剂。这种球墨鑄铁的土法压力加鎂試驗,設备非常简单,只要将普通铁水包稍加改裝即成。在处理球墨鑄铁时,没有耀眼的火花,不会有飞溅的铁水,沒有弥漫滿空的烟尘,十分安全可靠。新球化是利用白云石加少量的硅或铝为原料,在常压和不太高的温度下 Nanjing Automobile Works foundry workshop technicians and casting group, blasting group of workers in cooperation, has successfully tested the indigenous pressure plus magnesium and the new nodulizer. This nodular cast iron soil pressure plus magnesium test, the equipment is very simple, as long as the ordinary hot metal package a little Serve. Nodular cast iron in the treatment, there is no bright sparks, there will be no splash of molten iron, there is no full of empty smoke, very safe and reliable. The new ball is the use of dolomite plus a small amount of silicon or aluminum as raw material, at atmospheric pressure and not too high temperature
