Analysis of the advantages of forging steel ball
The ball ball mill on the market can be divided into two types according to the manufacturing process: casting and forging, but their degree of wear is not the same. Similarly, they are used by the environment is also different, the following simple analysis of forging steel ball What are the main features:
Forging steel ball:
Good surface quality, impact resistance, toughness, good wear resistance, not broken and missing round. Is the metal heating temperature of 700-1300 ℃, the use of forging machinery for the metal blank to exert pressure, so that it has a plastic deformation to obtain a certain mechanical properties, a certain shape and size forging processing methods. Forging (forging and stamping) one of the two major components. By forging can eliminate the metal in the smelting process resulting loose castings and other defects, optimize the microstructure, at the same time due to save the integrity of the metal streamline, the mechanical properties of forgings generally better than the same material castings. Related machinery, high load, the working conditions of critical parts, in addition to the shape of the more available rolled sheet, profile or welded parts, the use of more forgings. In addition, the forged steel ball to wear must be the most wear-resistant materials, such as the national standard of 60Mn, 65Mn, or some companies independently developed high wear-resistant alloy steel materials, and recommended the use of large national steel mills, the same is a The quality of materials produced in different mills varies. The quality of forgings is up to 80% depending on the quality of materials, such as high manganese steel, good impact resistance, good toughness and good abrasion resistance , Not easy to break. Forged steel ball because of cheap, economical and durable features favored by the majority of users, such as the international mining giant Rio Tinto, BHP Billiton, Angul Gold, etc. are forged steel ball.
Forging production features:
(1) forging the heated metallic material into various shapes of tools, mechanical parts or blank, which means forging. Forging can change the internal structure of metal materials, refined crystal, improve its mechanical properties.
(2) forging production must use heating equipment, forging equipment and many auxiliary tools.
(3) forging equipment are steam hammer, air hammer, die forging hammer, mechanical hammer, plywood hammer, spring hammer, belt hammer, crank press, friction press, press, reaming machine, roll forging machine.
