我们曾利用化学硬化法先后生产了几百吨铸铁件,其中有形状简单的平板、复杂的架体,泥芯有多到10个以上的,外形尺寸从300到3000公厘,重量从200到21000公斤,壁厚从20到500公厘.下面介绍用化学硬化法铸造重型铸铁砧垫的情况: We have used chemical hardening method to produce hundreds of tons of cast iron pieces, including a simple shape of the plate, complex frame body, as many as 10 more mud cores, dimensions from 300 to 3000 mm, weight from 200 to 21000 kg, wall thickness from 20 to 500 mm. Here is the use of chemical hardening casting heavy cast iron anvil pad situation:
