The casting fluidity, ratio of line contraction, castingstress 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 castingstress are affected.
On the other hand, the improper heat treatment operation can not completely relieve the castingstress and remnant stress, and further enhances generation and expansion of cracks.
