Forged steel ball production process and mechanical properties Jun 11, 2018

Forged steel balls are used in the process of iron ore mines to grind the material medium of the ball mill equipment. During the process of use, the wear is mainly caused by the friction between the steel ball and the material between the balls of the ball mill. The role of important basic components, especially precision industrial steel balls, has played a significant role in the development of the national economy. Widely used in cement plants, power plants and so on.

Forged steel balls are used for high and low multi-element alloy steel balls in iron ore mines and high- and low-chromium multi-element alloy cast forgings. In the process of operation, their forged steel balls can be developed to a certain extent. Ф20mm-Ф150mm and high, medium and low Chrome Ф 17mm-Ф120mm. The ball has the dimensions, round geometry, very high hardness and good mechanical properties and has excellent qualities of wear resistance, no deformation, no cracking.

Forged steel balls are used in iron ore mines for operation in large and medium-sized mines, cement plants, thermal power plants, and other industries. They are highly praised by their customers to some extent, and the forging of their products can be changed to some extent. The internal structure of its metal material, grain refinement, improve its mechanical properties.

When forging steel balls are used in iron ore mines, they must use heating equipment, forging equipment and super multi-assist tools in the process of production. In general, the forging equipment will have a certain degree of concrete hammers and spring hammers. , air hammers, die forging hammers, mechanical hammers, machines, reaming machines, roll forging machines, etc.

The production process of forged steel balls used in iron ore mines is to a certain extent mainly the use of metal whose melting point is higher than that of raw materials to make molds, which are subdivided into permanent mold casting methods, die-casting methods, etc., subject to the melting point of the molds, can be Foundry metals are also limited, dewaxing,

This method can be used for the outer film casting method and the solid casting method to first copy the desired casting object with wax, then immersed in the ceramic containing pool and left to dry, so that the wax-made replica is covered with a ceramic outer membrane and the steps are repeated. Until the outer film is sufficient to support the casting process (approximately 1/4 inch to 1/8 inch), the wax in the mold is then melted and pulled away from the mold, after which the mold needs to be heated at high temperatures multiple times before it can be used for casting.
