CastingWhether the quality of the casting is inseparable is inseparable from the casting of the castings. In order to better obtain the castings that meet the standards, the casting operation procedures of the castings should be strictly implemented. If the castings are not poured in accordance with the rigorous casting operation procedures, there will be no way to obtain qualified castings. Therefore, it is very important to strictly follow the casting standards and specifications of the castings.

When pouring castings, the pouring temperature and pouring speed of the castings must be strictly controlled. So what exactly are the casting operation procedures for castings? What kind of matters should you pay attention to? Let Kaihua Xinrui Machinery Equipment Co., Ltd. take you to know:

1. Pouring temperature. Different pouring temperatures have a great impact on the quality of castings. Therefore, we must determine the appropriate pouring temperature in accordance with the alloy type, casting structure and mold characteristics of the casting we need to pouring. Under normal circumstances, the pouring temperature established when pouring the casting should be between 1540-1580 ℃;

2. Pouring speed. The speed of pouring is related to the speed of casting molding. Therefore, it is necessary to adopt different pouring speeds for castings of different standards under the condition that the gas in the cavity is discharged relatively smoothly. Under normal circumstances, we should adopt a faster pouring speed for standard simultaneous solidification castings, and for stainless steel castings that achieve sequential solidification, we should adopt a slower pouring speed;

3. Pay attention when pouring large and medium-sized stainless steel castings. The molten steel needs to stand for 2 minutes to start pouring;

4. After the casting is successfully poured, the weight and box clamps must be removed immediately after the casting is solidified, otherwise cracks will be formed in the stainless steel casting.

When pouring castings, everyone must strictly follow the casting standards and specifications to obtain non-casting parts that meet the standards.
