Steel casting process

The steel casting process mainly includes the following steps:

Process design: According to the part drawings and technical requirements, the casting process design is carried out, including determining the process parameters such as the pouring system, riser, and chill.

Model making: According to the process design, the model of the casting is made. Commonly used model materials include wood, metal, plastic, etc.

Modeling: Use modeling materials such as models and molding sand to make a casting corresponding to the shape of the casting.

Melting: Add scrap steel, pig iron, alloy and other raw materials into the steelmaking furnace in a certain proportion for melting to obtain molten steel that meets the composition requirements.

Pouring: Pour the molten steel into the mold.

Cooling and solidification: The molten steel cools and solidifies in the mold to form a casting.

Sand removal and cleaning: After the casting is cooled to a certain temperature, the casting is taken out of the mold and cleaned to remove the pouring head, burrs, etc.

Heat treatment: According to the material and use requirements of the casting, the corresponding heat treatment is carried out to improve the organization and performance of the casting.

Inspection: The casting is inspected in terms of appearance, size, mechanical properties, etc. to ensure that the quality of the casting meets the requirements.
