Stainless steel precision casting machinery and technical requirements in use process, the temperature of the stainless steel precision casting can ensure the melt in the injection process has a good liquidity. In the process of selecting the temperature, stainless steel precision casting need according to the transmission distance, transfer in the process of cooling and factors such as flow rate to effectively. Stainless steel precision casting, casting cracks tend to be low. In use, the need to make sure that alloy has a good ability of exhaust and contraction. In use process, created the orderly crystal condition, effectively improve the density of the products. Pouring temperature is generally high. Stainless steel precision casting for the small diameter steel ingot, due to the transition zone size is small, its mechanical performance is good, generally meet liquidity, not form a bright crystallization, temperature of 715 ~ 740 ℃, slab cracking tendency. Is very high. In the process of using stainless steel precision casting, its mechanical performance is generally higher than that of cast iron, but the poorer performance of the material. In the process of production, the product of the melting point of melting point higher than other materials. In the process of machining, liquid steel production easily. Oxidation conditions of stainless steel precision casting process, there are many problems in performance is largely due to molten steel flow is poor. In machining process, in order to effectively prevent the casting steel is set, the cast steel wall thickness not less than 8 mm. , the structure of stainless steel precision casting system is very simple. In use process, if cast iron, the section size of large equipment. Heat can be used in the process of machining, casting or casting.
