Whether the quality of stainless steel castings is up to standard is closely related to the pouring of stainless steel castings. In order to obtain qualified stainless steel castings, we should strictly implement the pouring operation procedure of stainless steel castings. If the stainless steel castings are not poured according to the strict pouring operation procedures of stainless steel castings, we will not be able to obtain the standard stainless steel castings. Therefore, it is very important to strictly follow the pouring standards of stainless steel castings.

When pouring stainless steel castings, we should strictly control the pouring temperature and pouring speed of stainless steel castings. Therefore, what are the casting operation procedures for stainless steel castings? What should we pay attention to? Let's introduce them to you

1. Pouring temperature. Different pouring temperature has a great influence on the quality of stainless steel castings. Therefore, we should determine the appropriate pouring temperature according to the alloy type, casting structure and mold characteristics of the stainless steel castings we need to pour. In general, the pouring temperature should be between 1 540-1580 ℃ when pouring stainless steel castings;

2. Pouring speed. The pouring speed is related to the forming speed of stainless steel casting. Therefore, we should adopt different pouring speed for different standard stainless steel castings under the condition of ensuring smooth gas discharge in the mold cavity. Generally, we should adopt faster pouring speed for standard simultaneous solidification of stainless steel castings, and slow pouring speed should be adopted for stainless steel castings with sequential solidification;

3. When pouring large and medium-sized stainless steel castings, we should pay attention to that the molten steel needs to stand for 2 minutes before pouring;

4. After the stainless steel casting is poured successfully, the pressure iron and box clamp should be removed immediately after the casting is solidified, otherwise the stainless steel casting will form cracks.

When pouring stainless steel castings, we must strictly follow the pouring standards to obtain the standard stainless steel castings.
