【摘要】 设计了铸件变形强化测试装置,测定了几种不同材质的铸件抗变形能力。在实验室研究数据的基础上,选定材质,在生产现场做了几种铸件取消热时效试验,结果表明,选择高Si/C比铸铁,可使一定类型铸件取消热时效。更多还原

【Abstract】 In this paper,an apparatus for distortion intensive measurement of casting is designed to test the distortion resistance of several kind of casting materials. According to the data taken in laboratory with this apparatus, certain kind of casting materials were chosen for the experiment of abolishing stress relieving process of some casting in factory. The results-show that using the high Si/C ratio casting as a substitute for common Si/C one, the stress relieving process can be abolished for certain kind of casting.更多还原
