The deformation of the casting method of prevention and cure: 

A. large planar casting set stiffeners, mold design against deformation; 

B. casting wall thickness design transition not too large, the cross section shape is symmetrical; 

C. measures should be taken in the casting process, the solidification at the same time; 

D. for long and thin, easy to deformation of the casting in the manufacture the model, the modelis made with the shape of the deformation direction opposite to offset its deformation, the method for the deformation laws.

The casting crack prevention and cure:

A.molten steel purity is higher. Using high quality raw materials; 

B. avoid casting shrinkage is blocked; 

C. type pouring temperature shoulds not be too low. 

D. control mold cooling type time e. castings by slow cooling with 

F. improvement design of die structure and avoid sharp corners, wall thickness to uniform and smooth transition.
