There are a lot of industries that have prospects for investment ventures, such as the free sample cutting disc industry. Because the construction industry now uses a lot of steel, the steel needs to be cut before it can be used, which uses the free sample cutting disc. Need a large number of products. Cutting plate texture should be hard, wear-resistant, long service life, etc. Today, we will analyze the service life and what is relevant.
Henan Aurora Abrasives manufacturer Aurora believes that its service life is related to its materials. The commonly used abrasives for cutting wheels are brown jade (A), white corundum (wA), black corundum (BA), black silicon carbide (c), etc. It is brown fused alumina, because brown fused alumina has high hardness, high toughness, sharp particles, strong applicability and low price compared with other abrasives. Brown fused alumina is divided into primary sand and secondary sand according to its reduction during smelting. Mainly in chemical composition: Al2O3 content of primary sand is ≥94.5; Al2O3 content of secondary sand is <94.5%; generally about 85%, and Fe2O3 content is 4~5%; therefore, secondary sand hardness is higher than first grade The sand is low, but the price is low.
