制造高级铸铁时,我们知道可以下加矽铁或其他孕育剂,只要加入适量的铁水(含矽稍多)也可得到同样效果。如果能够引用到球墨铸铁的制造上,不但可以降低成本,而且可提高浇铸温度,使球墨铸铁得到较好的补缩,减少缩孔和缩松的现象。我厂会从事于这样的试验,希望铸造工作者,根据我们的试验,提供意见。 When manufacturing high-grade cast iron, we know that we can add ferrosilicon or other inoculants as long as we add the same amount of hot metal (with slightly more silicon) to achieve the same result. If we can refer to the manufacture of ductile iron, not only can reduce costs, but also improve the casting temperature, so ductile iron get better shrinkage, reducing shrinkage and shrinkage phenomenon. I plant will be engaged in such a trial, I hope foundry workers, based on our trial, provide advice.
