Ductile Iron casting sand and sand holes within the sand mold is the cause of sand cleaning not clean,there are residual gravel. In is in the process of casting,because the iron liquid scour sprue wall caused by the sand. Some manufacturers use besmear brushs paint to prevent,take a good result,but still there will be a ductile castings in sand inclusion,sand holes. Because gate besmear brushs paint more suffering. In is high pouring temperature in casting process,washing,soaking coating in the erosion and high temperature is easy to fall off. Caused the sand inclusion sand holes. Between this kind of problem,we can from the following ways to solve:
Ductile Iron casting yield,enhance ductile casting quality,and reduce the total cost of the casting gate earthenware pipe,ductile castings this product easy to use,has a smooth flow,resistance to molten iron,molten steel wash,do not absorb liquid steel,can be saw is good wait for a characteristic,can simplify the modeling process,eliminating the difficulty of the gate on the inside of the paint work,and to improve the pouring system layout,avoid ductile casting sand washing,sand holes,sand defects. To improve the quality of ductile cast and ductile casting yield play a large role,especially in all kinds of the rigid casting shape,the characteristic is more outstanding.
