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.
Temperature to determine the melt in the process of reinjection of good mobility, the choice of detailed mechanical processing temperature should be based on the distance of reinjection, reinjection of the process of cooling conditions, alloy, specifications, flow and other factors to determine the detailed mechanical processing temperature than the alloy liquid-phase line temperature is higher than the temperature of the liquid-phase line of 50 to 110 ℃. Production temperature can determine its melt in the process of reinjection will have good fluidity, equipment in the process of selecting its casting temperature needs to be based on its reinjection distance and reinjection process cooling conditions and other factors to determine.
