The temperature of stainless steel precision casting processing ensures good activity of the melt during the injection process. The selection of stainless steel precision forging temperature should be based on the interval of injection and the cooling process. The temperature of stainless steel precision forging processing is 50 to 110 ℃ higher than the alloy liquidus temperature. So what are the process measures for stainless steel precision casting that everyone knows?
The process measures for stainless steel precision casting are as follows:
1. Due to the poor activity of molten steel, in order to prevent cold shuts and insufficient pouring of stainless steel castings, the wall thickness of stainless steel castings cannot be less than 8mm.
2. Because the shrinkage of stainless steel castings during forging is much greater than that of cast iron, in order to prevent shrinkage in castings, the forging process mostly adopts errors such as risers, cold iron, and subsidies to achieve sequential solidification.
Stainless steel precision forged castings are widely used in mechanical components such as injection molding machines, gas turbines, steam turbines, compressors, sewing machines, weapons, and office machinery.
The crack tendency of stainless steel precision casting processing round ingots is low, which is due to the good exhaust and contraction ability of the cladding alloy, the creation of sequential crystallization conditions, the improvement of density, and the higher temperature of ordinary forging.
The main process measures for stainless steel precision casting are introduced above. When operating and using our stainless steel precision casting, we all need to follow the above process measures to operate and use our stainless steel precision casting.
