Details of machining, forging and casting

In the process of using detailed mechanical processing, its mechanical properties are better than cast iron, but the cast iron properties of this material is poor, the melting point is higher than other materials. Its in the process of processing need to pay attention to the problem is quite a lot, mainly because of the liquidity of the steel is relatively poor, in the process of processing, we are in order to prevent the meticulous mechanical processing to produce insufficient pouring or cold segregation, meticulous mechanical processing of the wall thickness is not less than 8mm. The structure of the casting system is relatively simple, in the process of using its equipment in the cross-section size if the cast iron is large, so that in the process of processing can also be used in its hot casting or dry casting.
