The casting fluidity, ratio of line contraction, casting stress and heat crack tendency were tested.

分析测定了中铬抗磨铸钢的流动性、缩孔率和铸造应力。

Mechanical stress can obviously affect intensity, distribution of stress through the experiments and tests. The produce and form of casting stress are affected.

通过在实验室与生产条件下所进行的判断性试验确证，机械阻碍应力对铸造残余应力的大小、分布有着极为显著的影响。

On the other hand, the improper heat treatment operation can not completely relieve the casting stress and remnant stress, and further enhances generation and expansion of cracks.

另一方面，热处理工艺不当使得铸造应力及机加工的残余应力无法彻底消除，这样加剧了裂纹的产生和扩展。
