Now the ball mill in the market according to the manufacturing process can be divided into two types: casting and forging, but their wear degree is not the same. Because of the broken material, the steel ball needs good abrasion resistance and need enough toughness, usually used in alloy steel, high manganese steel, cast iron and other materials such as chromium iron with a forging or casting method, with the corresponding heat treatment process is more economical, ball mill steel ball according to process and material can be divided into: 1, forged steel ball: low-carbon alloy steel ball, Medium carbon alloy steel ball, high manganese steel ball, rare earth chromium molybdenum alloy steel ball; 2, cast steel ball: Low chromium cast ball, medium chromium cast ball, high chromium cast ball. What kind of steel ball is best in the market now? Now let's analyze: 1. Forged STEEL Ball: good surface quality, good impact resistance, toughness, good wear resistance, not easy to break and lost round. is the metal heating temperature up to 1050 ℃ (positive or negative 50 degrees), the use of forging machinery to the metal billet pressure, so that it produces plastic deformation to obtain a certain mechanical properties, a certain shape and size forgings processing methods. Forging (forging and stamping) is one of the two major components. The forging can eliminate the defects such as the loose cast in the smelting process, optimize the microstructure, and the mechanical properties of the forgings are generally superior to those of the same material because the complete metal streamline is preserved. The important parts with high load and severe working conditions in the related machinery, besides the simple shape can be used for rolling plate, profile or welding parts, the forging is more adopted.
