Technical Field

[0001] The utility model relates to the technical field of steel ball processing, in particular to a thermal power generation steel ball heat treatment combined device. Background Art

[0002] In thermal power plants, coal is a major fuel. After being processed by a coal mill, coal can be pulverized into coal suitable for combustion to generate electricity. A coal mill usually places a certain amount of steel balls in a rotating cylinder, and then puts ore or other raw materials into the cylinder. As the cylinder rotates, the steel balls rotate with the raw materials and collide and rub against each other, thereby grinding the raw materials.

[0003] This type of steel ball requires a higher hardness, so during the production process of the steel ball, a series of heating and cooling heat treatment processes are required to change the organizational structure and properties of the steel. Such treatment can increase the hardness of the steel ball.

[0004] When quenching steel balls, they are often placed in oil. Although water cooling is fast, it is easy to form cracks or become brittle, while oil cooling is relatively slow and gentler than water cooling, which can reduce the risk of crack formation and enable the steel balls to reach a suitable hardness. However, after oil quenching, oil will remain on the surface of the steel, and these residues may have a negative impact on subsequent processes or the use environment. Therefore, it is necessary to design a thermal power steel ball heat treatment combination device to solve the above problems. Utility Model Content
