一、前言人们早已发现了在可锻铸铁中提高含硅量可以缩短石墨化时间。40年代国外曾做过低硅范围内含硅量对石墨化过程影响的试验,但中硅及高硅范围内是否有着和低硅范围相同的规律呢?我国目前大多数厂生产中硅或高硅可锻铸铁,为了能适应这种现状,我们对中硅和

I. Preface It has long been discovered that increasing the silicon content in malleable cast iron can shorten the graphitization time. In the 1940s, overseas experiments on the effect of silicon content in low-silicon range on graphitization have been done in foreign countries. However, are there any laws in the range of medium- and high-silicon with the same range as low-silicon? Most silicon in our country currently produces silicon or high Silicon malleable iron, in order to adapt to this situation, we are on the silicon and
