(Summary description)Stainless steel precision castings are a useful production process in steel enterprises, widely used, and can be cast in various types and aluminum. So, what is your suggestion for cracks in stainless steel precision castings? The suggestions for cracking in stainless steel precision castings are shown below: 1. Heating, when dealing with defects in stainless steel plate castings, should adhere to heating standards. During the entire process of blowing welding, the product workpiece should be heated to above 108 ℃. 2. In the smelting process, minimize the composition of harmful elements such as P.S, and reduce the composition of gases such as N.H.O and dirt as much as possible. Low phosphorus steel intermediate aluminum alloy profiles can produce good results. 3. Thermal insulation: According to the appropriate increase in the thermal insulation time of sand castings, it is important to control the unpacking working temperature to be less than 70 ℃, ensure that the sand castings are fully packed with liquid and solid materials, and avoid internal stress caused by external forces. 4. When sand falls, it is strictly prohibited to irrigate the sand mold and castings during the sand removal step of the casting. It is strictly prohibited to use strong external forces such as box collision to cause destructive sand falls, and to avoid the mutual influence of external forces and internal stress of the casting, causing cracks. 5. Fiber laser cutting of the glue inlet, select the appropriate process for making the sincere pouring glue inlet according to the casting specifications, and ensure that the sincere working temperature is not less than 300 ℃. 6. For the structure of stainless steel plate castings, comprehensive consideration should be given to factors that can damage the liquid and solid collapse of the castings during the entire forging process, such as pattern, large thickness, and docking. Choose appropriate technical basic parameters to prevent defects, such as folding and folding. Stainless steel forging. When cracks occur in high-precision stainless steel castings, we can follow the above operation process and apply our castings.
