含锆硅铁对含铅、砷、锡生铁使用性能的改善作用

The Amelioration Effect of Ferro silico zirconium on the Vsability of Pig Iron Containing Lead, Arsenic and Tin

用含锆硅铁以及它的复合合金对含铅、砷、锡等杂质元素的铸铁进行孕育处理，可以有效地改善铸铁的组织和性能。生产应用表明，用这种方法处理的铸铁，裂纹倾向明显减少。

Inoculating the cast iron containing lead, complex alloy can improve effectively the structure and properties of the cast iron. The application in the production indicates that the crack tendency of the cast iron treated by this way will be reduced apparently.
