钾钠对球铁点状石墨及性能的影响

The Efgfect of K-Na Influenced on Needle Graphite and Mechanical Propertics

研究了在特定的砂型条件下 (K－ Na＋ Si－ Fe)对铁液的作用，结果表明：钾纳孕育剂在消除点状石墨、提高力学性能特别是伸长率方面有良好的效果。

The effect of the (K－ Na＋ Si－ Fe)on the molten iron is studied using special sand mold in this paper.The experiment results indicate that K－ Na has an obviously good effect on eliminating the needle graphite and increasing the mechanical properties,especially the ductility.
