汽车工业部门迅速认识到球墨铸铁给设计工程师们提供了一种降低配件成本的方法。自从用镁处理铸铁方法发表后,不到一年,就进行了球墨铸铁曲轴试验,至52年福特汽车公司的铸造曲轴几乎全用球墨铸铁。通用汽车公司决定在1970型卡迪克拉斯克汽车上按装一批球墨铸铁转向节,就更说明了球墨铸铁在质量控制和冶金工艺方面都取得了显著进步。在某些重要应用场合,球铁代替了以前使用的锻件和冲压件,也表明某些著
The automotive industry quickly realized that ductile iron gave design engineers a way to reduce parts costs. Nodular cast iron crankshaft tests have been conducted in less than a year since the method of treating cast iron with magnesium has been introduced. To 52 years Ford Motor Company’s cast crankshaft is almost entirely made of ductile iron. General Motors decided to install a number of ductile iron knuckles on the 1970 Cadillacs, demonstrating even more significant improvements in quality control and metallurgical processes. In some important applications, ductile iron used to replace the previously used forgings and stampings, also shows that some
