First, cast iron geometry, size, size effect and solidification, shrinkage, stress. Second, cast iron structure, weight and size. Third, the quality of raw materials for casting iron castings. The substandard quality of metal charge, refractory material, fuel, flux, modifier, casting sand, molding sand binder, paint and other materials will cause defects such as porosity, pinhole, slag inclusion, sand sticking, etc., which will affect the appearance quality and internal quality of cast iron parts, and will cause cast iron parts to be scrapped in serious cases.
