What should I pay attention to in the production process of stainless steel casting?

Stainless steel casting is a casting process with little or no cutting, which is an excellent technology in the foundry industry, and it is widely used. So you know what stainless steel casting process should pay attention to in the production process?

The matters needing attention in the stainless steel casting process are as follows:

The main results are as follows: 1. Because the shrinkage of cast steel is much higher than that of cast iron, in order to prevent the defects of shrinkage and porosity of castings, riser, cold iron and subsidy are mostly adopted in the casting process to realize sequential solidification. In addition, in order to prevent steel castings from producing shrinkage, porosity, pores and cracks, the wall thickness should be uniform, sharp-angle and right-angle structures should be avoided, sawdust should be added to the mold sand and hollow core and oil sand core should be used to improve the concession and air permeability of the mold or core.

2. Due to the poor fluidity of molten steel, in order to prevent cold insulation and insufficient pouring of steel castings, the wall thickness of steel castings should not be less than 8mm; the structure of the gating system should be simple and the section size is larger than that of cast iron; dry or hot casting moulds are adopted; the pouring temperature is generally 1520 ℃ ~ 1600 ℃, because the pouring temperature is high, the superheat of molten steel is large, and the liquid state is kept for a long time, and the fluidity can be obtained.
