The stainless steel precision casting temperature can effectively guarantee the fluidity of the melt in the process of transfer.In the process of temperature selection of stainless steel precision casting, some factors such as the distance of the transfer and the cooling conditions and the flow rate are determined.
H3. Stainless steel precision casting round ingot has low crack tendency.In this way, it can effectively guarantee that the alloy has good exhaust and shrinkage ability.Effective creation of its order approximation conditions,ncrease its density,General casting temperature will be on the high side, so that the diameter will be more than 350 mm in the ingot casting temperature is 730 ~ 750 ℃ in general.
H4. Stainless steel precision casting because its transition belt is small,its mechanical properties are good when used.44/5000
In general, it can satisfy its fluidity to a certain extent, and the normal temperature is 715~740.The stainless steel precision casting slab has a high thermal crack tendency, and the precision casting temperature of stainless steel is lower, usually 680~735.
H5. Stainless steel precision casting can effectively make moulds according to its different shape.The casting mould of the product can be effectively divided into up and down mold,Through milling, erosion, electric spark and other comprehensive process. The shape and size of the pit are the same as the product.
H6. Stainless steel precision foundry manufacturer at the set room temperature, let spray the first layer of fine sand mold natural air drying.But it cannot affect the change of internal wax pattern.The time of natural air drying depends on the complexity of the product itself. The first dry time of the casting is about 5-8 hours.
H7. Stainless steel precision casting will effectively fix the baking process in the mould head,Then, the wax model of the sand blast drying process is effectively completed in the special oven of metal sealing, which is heated in a special oven. The melting point of industrial wax is not high, and the temperature is about 150.
