Advantages of Forged Grinding Balls
Forged steel ball: good surface quality, good impact resistance, strong toughness, good wear resistance, not easy to break and out of round.
It is a processing method that the metal heating temperature is 700-1300 ℃, and the forging machine is used to exert pressure on the metal blank to produce plastic deformation, so as to obtain the forging with certain mechanical properties, certain shape and size. One of the two major components of forging (forging and stamping).
Forging can eliminate the defects such as loose as cast state and optimize the microstructure. Meanwhile, due to the preservation of complete metal streamline, the mechanical properties of forgings are generally better than those of castings of the same material. For the important parts with high load and severe working conditions, forgings are often used except for the simple shape of plates, profiles or weldments that can be rolled
In addition, the most wear-resistant materials must be selected for forging steel balls, such as the national standard of 60Mn, 65Mn, or the high-efficiency wear-resistant alloy steel materials independently developed by some companies. Moreover, it is suggested that the steel produced by the national super large steel plant is the same material, and the quality produced in different steel plants is also different. The quality of forging 80% depends on the quality of the material If high manganese steel is used, it has good impact resistance, strong toughness, good wear resistance and is not easy to be broken.
Forged steel balls are favored by the majority of users because of their low price, economy and durability. For example, the international mining giants Rio Tinto, BHP Billiton and Angelu gold all use forged steel balls.
