SAND CASTING EQUIPMENT.

The casting process is a crucial link in the entire production process of steel castings. If this link is not handled properly, it is difficult to cast qualified steel castings. Therefore, in the production of steel castings, the casting process should be carried out in strict accordance with the requirements. Item operation. First of all, enterprises should make sufficient preparations before pouring to ensure that the subsequent casting operations can proceed smoothly.
Preparations before casting include:
1. Clean the pouring site to ensure the safe and smooth completion of the pouring process;
2. Check the repair quality of the ladle, the drying and preheating condition, and the flexibility and reliability of the transportation and tilting mechanism;
3. Understand the types of casting alloys, estimate the number of casting molds to be cast and the weight of molten metal required to prevent insufficient molten metal and insufficient casting molds during pouring. In order to obtain qualified steel castings, it is critical to strictly control the casting temperature and casting speed, and strictly abide by the casting operating procedures.
3.1 As far as the casting temperature is concerned, the casting temperature has a great influence on the quality of castings. A reasonable casting temperature range should be determined according to the alloy type, casting structure and mold characteristics. Choose a reasonable casting temperature according to the model of carbon steel. Generally, the casting temperature is between 1540℃～1580℃ of molten steel in the ladle.
3.2 As far as the casting speed is concerned, under the condition that the gas in the cavity is discharged smoothly, a higher casting speed can be used for castings that require simultaneous solidification, and a lower casting speed should be used for castings that require sequential solidification.
3.3 As far as the casting operation requirements are concerned, the following points should generally be observed: casting large and medium-sized steel castings, the molten steel should be placed in the ladle for 1min to 2min before being sedated for casting; after casting, the casting should be removed in time when the casting is solidified Weight iron and box clamps to reduce the shrinkage resistance of castings and avoid cracks in castings. In terms of the current proportion of castings of various materials, steel castings have accounted for about 12% of the total output of castings of various materials in recent years. They have a great influence on the development of the entire casting industry and are reasonable in the production of steel castings. Arrange all links to improve the quality of steel castings so as to promote the development of the entire casting industry.

Xinyuanzhu Group has a complete casting system and adopts automated casting equipment, which can realize quantitative production and reduce the waste of resources caused by manual casting. It can undertake casting processing of various steel castings. Guests are welcome to visit the factory.
