浇杯孕育工艺在我厂试用成功以后,1973年 3月曾在我厂的生产条件下,以 295曲轴为对象,研究了不同硅铁孕育量对曲轴金相组织和常规机械性能的影响,总结成《浇杯孕育工艺对295球墨铸铁曲轴组织和机械性能的影响》一文[1]。当时我们发现在浇杯孕育工艺中,存在一个合理的孕育量问题,对于295曲 Pouring cup inoculation process in my factory after the successful trial, in 1973 March in my factory production conditions, to 295 crankshaft for the study of different ferrosilicon on the crankshaft of the microstructure and conventional mechanical properties of the impact summary Into a "pouring cup birth process on 295 ductile iron crankshaft organization and mechanical properties of a paper [1]. At that time, we found that in the pouring cup inoculation process, there is a reasonable gestation problem, for the 295 song
