Production technology of bearing steel grit

　　Bearing steel grit is also called high-manganese alloy steel grit, alloy steel grit, etc. It is made of bearing steel that has been crushed, tempered, and sieved into metal particles of large and small sizes. High, suitable for stone cutting, engraving, and high-hardness steel surface rapid descaling pretreatment.

　　Bearing steel grit is made of high chromium bearing steel. Due to the high chromium content, it has good hardness, high-quality bearing scraps, and unique patented technology. Through innovation in production technology, without smelting procedures, the product has high density and few defects. , Good metallographic structure, good toughness and fatigue resistance, long service life, forged bearing steel grit with sharp edges, has higher mechanical properties than traditional cast steel grits with spherical surfaces.

　　1. This product uses high-quality bearing scraps, uses unique patented technology, innovates in production technology, does not go through smelting procedures, the product has high density, few defects, good metallographic structure, superior mechanical properties, good toughness and fatigue resistance. Long service life, low consumption and so on.

　　The raw material of bearing steel grit is bearing steel. Bearing steel is high-purity iron-carbon alloy steel. Bearing steel is the steel used to make balls, rollers and bearing rings. Bearing steel has high and uniform hardness and wear resistance, as well as a high elastic limit. The uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict, and it is one of the most demanding steel types in all steel production. So its price is naturally much higher than that of ordinary scrap steel. Bearing steel grit is directly quenched with forged bearing steel and broken into steel grit. There is no melting process in the manufacturing process, and there is no casting defect. It is an energy-saving and pollution-free product. Compared with cast steel grit, bearing steel grit can be used as In addition to cleaning products, it can also be used as an abrasive for making abrasive tools to polish and grind bearings and other workpieces. Bearing steel sand contains precious metal-chromium element, which enhances the fatigue life and wear resistance of the product itself. Through the unique production process, the metallographic structure is excellent, the product particles are full, the hardness is uniform, the fatigue life is long, and the impact resistance, High wear resistance can effectively improve the recycling rate (abrasives are gradually reduced during the sandblasting process), thereby reducing the consumption rate of abrasives by more than 30%. Bearing steel grit is a high-quality steel grit that can meet high standards, high requirements, and high quality in the world.
