本文在有关研究成果基础上,进一步研究了可锻铸铁碲基孕育剂。通过大量实验,证实了碲铝孕育剂的孕育效果稳定,在正常生产化学成分情况下,能保证获得铸态白口组织,对固态石墨化和机械性能无不利影响,特别是当用粗碲铝孕育剂代替铋铝孕育剂时,还可以使铸件成本降低。 Based on the relevant research results, this paper further studies the malleable cast iron iron-based inoculant. Through a large number of experiments, the inoculation effect of aluminum telluride inoculant has been confirmed to be stable. In the case of normal production of chemical composition, the white castings can be obtained with no adverse effect on the solid state graphitization and the mechanical properties. In particular, Inoculation agent instead of bismuth aluminum inoculant, you can also make the casting cost reduction.
