[0002] Steel castings refer to parts made of cast steel, which have similar properties to cast iron, but better strength than cast iron. One of the advantages of steel castings is the flexibility of design. Designers have the greatest freedom to choose the shape and size of the castings, especially parts with complex shapes and hollow sections. Steel castings can be manufactured using the unique process of core assembly. They are widely used in ships and vehicles, construction machinery, engineering machinery, power station equipment, mining machinery and metallurgical equipment, aviation and aerospace equipment, oil wells and chemical equipment.

[0003] The melting point of cast steel is relatively high, and high temperature auxiliary forging is required during casting. After casting, the cast steel parts need to be placed on a cooling rack for cooling. Currently, commonly used cooling racks are generally of fixed size when used. However, when casting different steel parts, there are cast steel parts of different sizes. During cooling, multiple different cooling racks need to be set up, which is inconvenient to use. As a result, the cooling rack has a low applicability when used, and is not convenient to adjust and use according to different situations. The use effect is poor. Therefore, technical personnel in this field provide a cooling rack for cast steel parts to solve the problems raised in the above background technology. Utility Model Content
