Description
If the casting temperature of stainless steel castings is too high, it will cause sand mold expansion, especially for auto parts with complex sand cores. When the casting temperature of stainless steel castings is ≥1420 ° C, the waste will increase, and the waste products will reach 50% when the casting temperature is 1460 ° C. In production, the use of induction furnace melting can better control the temperature of molten iron.
Defects that may be formed when the casting temperature of stainless steel castings is too low.
(1) Manganese sulphide pores This type of pores are located below and mostly on the skin of auto parts, and are often exposed after processing. The diameter of the pores is about 2 ~ 6mm. Sometimes the pores contain a small amount of slag. Metallographic studies show that this defect is caused by the mixture of MnS segregation and slag, because the casting temperature of stainless steel castings is low, and the amount of Mn and S in the molten iron is high.
This S content and the appropriate Mn content (0.5% ~ 0.65%) can significantly improve the purity of the molten iron, thereby effectively preventing such defects.
(2) Stomata caused by sand core gas Stomata and air holes are often caused by poor venting of the sand core. Because the sand core is hardened in the core box when making the core, this often makes the number of sand core exhaust holes insufficient. To form vent holes, drill holes can be added after the core has hardened.
(3) Liquid slag inclusion After processing, there will be individual small holes under the skin of the auto parts. The diameter of the holes is generally 1 ~ 3mm. In some cases, there are only 1 or 2 small holes. Metallographic studies show that these small pores appear with a small amount of liquid slag inclusion, but no segregation of S is found there. Research shows that this defect is related to the casting temperature of stainless steel castings. When the casting temperature of stainless steel castings is higher than 1380 ° C, no such defects are found in the castings, so the casting temperature of stainless steel castings should be controlled at 1380-1420 ° C. It is worth mentioning that the design of the gating system has been changed and this defect has not been eliminated. Therefore, such defects can be considered to be due to the low casting temperature of stainless steel castings and the formation of molten iron in a trace reducing atmosphere.
The casting temperature of stainless steel castings is too low to avoid.
