What factors affect the quality of cast iron parts?This site believes that the first iron geometry, size, size effect and solidification, shrinkage, stress.Second, structure, weight and size.The third is the quality of the raw materials used for casting.The quality of metal furnace material, refractory materials, fuel, flux, metamorphic agent and cast sand, type sand binder, coating and other materials is not in standard, which will make the cast iron parts produce pores, pinhole, slag, sticky sand and other defects, affecting the appearance quality and internal quality of the cast iron parts, and the cast iron will be scrapped.The fourth is the process operation, to develop a reasonable process operation procedures, improve the technical level of workers, so that the process procedures are correctly implemented.
