Detailed explanation of the structure and temperature of precision casting

The mechanical properties of stainless steel precision casting in the production process are higher than that of precision cast iron, but the cast iron performance of this material will be worse than that of stainless steel precision casting, and the melting point during the production process is higher than that of other materials of precision cast iron.
Due to the poor flow properties of stainless steel for precision casting, in order to prevent insufficient pouring or cold separation during processing, the wall thickness of steel castings should not be less than 8mm. Therefore, for stainless steel precision casting, there are many problems that need to be paid attention to. .
The structural force of the stainless steel precision casting pouring system is very simple. If the equipment has a large cross-sectional size during the production process, the hot or dry casting can also be used in the production process.
The stainless steel precision casting temperature in the transfer process guarantees good melt fluidity. When selecting the stainless steel precision casting temperature, it should be based on the transfer distance, the cooling conditions of the transfer process, alloy, specifications, flow and other factors, and comprehensively consider multiple factors to 50 ~110℃ is suitable.
The precision casting processing temperature can effectively ensure that the melt in the precision casting process has good fluidity to a certain extent. When selecting the precision casting processing temperature, the equipment selection should be determined according to the processing distance, cooling conditions and other factors.
Stainless steel precision casting has a low cracking tendency. During use, it is necessary to effectively ensure that its alloy has a good discharge and feeding ability, so as to create conditions for continuous crystallization to a certain extent, thereby increasing its density. Generally, the casting temperature is relatively high. .
