In the process of meticulous machining, its mechanical properties are better than cast iron, but the cast iron properties of this material are poor, and the melting point is higher than other materials. There are many problems that need to be paid attention to in the process of processing, mainly because the flow performance of molten steel is relatively poor. In the process of processing, in order to prevent insufficient pouring or cold insulation from meticulous machining, the wall thickness of meticulous machining cannot be less than 8mm. The structural force of the gating system is relatively simple, in the process of using the equipment in the cross-sectional size of cast iron is large, so in the process of processing can also be used in the hot casting mold or dry casting mold.

The temperature determines the good fluidity of the melt in the transfer process. The selection of the detailed machining temperature should be determined according to the distance of the transfer, the cooling situation during the transfer process, the alloy, the specification, the flow rate and other factors. The detailed machining temperature is 50 to 110 ℃ higher than the liquidus temperature of the alloy. The production temperature can determine that the melt will have good fluidity in the process of transfer injection. In the process of selecting the casting temperature, the equipment needs to be determined according to some factors such as the distance of transfer injection and the cooling of transfer injection process.
