Precision cast iron pieces
Precision cast iron pieces
Xi'an castings in the precision cast iron and sand in the performance of a significant difference, such as sandy permeability, and metal cast iron pieces are not; sand type of poor thermal conductivity, metal-type cast iron pieces of the thermal conductivity is very good, Sex, and metal-type cast iron pieces did not wait.The metal cast iron pieces of these characteristics determine its formation in the casting process has its own laws. Xi'an castings of metal cast iron pieces of the impact of contraction on the cast iron parts: metal cast iron or metal cast iron core, hinder casting shrinkage. Casting parts in the solidification process, the hot metal liquid will heat transfer to the metal cast iron wall. Liquid metal through the amount of heat, solidification process shrinkage, and the wall in the heat, increase the temperature at the same time produce expansion, the result in the casting and the wall formed between the "gap." Before the "cast-gap-metal cast iron" system does not reach the same temperature, the casting can be considered to be cooled in the "gap" and the metal cast iron wall is heated by "gap". Xi'an castings of metal castings hinder the impact of shrinkage on the cast iron parts: metal cast iron or metal cast iron core, in the casting solidification of the non-commemorative cooperation, hinder casting shrinkage, which is another feature of it.

The shape of the gas changes in the cavity of the castings of metal castings hindered the impact of shrinking on the cast iron parts: metal cast iron or metal cast iron core, in the casting solidification of the non-concession, the casting shrinkage, which is its Another feature: the impact of molding: metal in the filling, the cavity of the gas must be quickly discharged, but the metal and no breathability, as long as the process a little negligence, it will give the quality of cast iron adversely affected.
