The main characteristics of the grinding steel ball in the process of its use are: impact resistance, toughness, moderate hardness, and can be repeatedly used several times in a row. The grinding ball has long life, good resilience and strong adhesion. The cleaning speed is fast, low sand consumption, no crushing, clean workpieces with large brightness and good technical effects.
The cleanliness of the surface of the polished steel ball after its treatment can reach an international standard to a certain extent. The roughness of the surface of the product can reach 25-100um, thereby increasing the contact surface of the metal surface and improving the application. The surface adhesion, on the refinement of the metal surface to strengthen the metal structure, has very significant economic benefits.
Grinding steel ball is usually produced by forging process in the process of production, and the product contains more than 12% of chromium, and the steel can resist chemical attack. Stainless steel does not rust, but does not easily rust. The principle is to form a dense layer of chromium oxide on the surface of steel by the addition of chromium, which can effectively block the re-contact between steel and air, so that the oxygen in the air can not enter the steel, so as to prevent the steel from being born. Rust effect.
Grinding steel ball quality standards
The material used for grinding the steel ball in the process of operation is mainly bearing steel. On this basis, GCr15SiMn and martensitic stainless steel balls with better wear resistance are produced, which is the only enterprise that currently forms series products in China. Products are widely used in the ink manufacturing industry.
