The first step: Simulation and modeling

 

Before casting, numerically simulate the casting process by CAE software to analyze the molding process, predict and optimize the product quality. Metallurgical auxiliary devices are complete to control the overall size well. Water glass sand molding process can prevent the hot cracks on castings, and the pit moulding is efficient and not subject to the effects of season.

 

The second step: pouring and heat treatment

 

The qualified raw and auxiliary materials shall be put into the arc furnace according to the proportion, and the sampling of hot metal shall be carried out to perform the spectral analysis. After qualification, the pouring shall be carried out according to the principle of "low temperature and quick casting", and the pouring time and temperature shall be recorded.

 

The third step: polishing and flaw detection

 

Finally, cut the pouring riser and burr etc. CHAENG has professional mechanical polishing teams and large-scale blasting apparatus, which can effectively improve the appearance quality of support roller, to meet customer’s requirements on surface finish. Moreover CHAENG take use of advanced detection equipment for non-destructive testing to ensure the internal quality of supporting roller, strictly stop any defective goods from leaving the factory.
