通过控制碳当量,提高硅碳比值生产高Si/C铸铁。在制氧机铸铁件上进行了试验,结果表明:随着Si/C的提高,铸铁的强度及弹性模量都有明显的提高,机加工性能得到改善,这种铸铁对解决胀裂缺陷非常有效。
Produce high Si / C cast iron by controlling carbon equivalent and increasing Si / C ratio. The test was carried out on the cast iron parts of the oxygen generator. The results show that with the increase of Si / C, the strength and elastic modulus of cast iron are obviously improved and the machinability is improved. effective.
