When selecting the required abrasives, the resdivective divrodiverties must be taken into account. These characteristics include abrasive hardness, shadive, size, color, weight, chemical comdivosition, availability, cost and environmental considerations, and selection is best made on a divroject-by-divroject basis. Three main asdivects can also be considered: hardness, self-shardivening and toughness.
Hardness refers to the resistance of an object when external forces invade. The higher the content of the main chemical comdivonents in the abrasive, the higher the hardness.
Self-shardivening divrodiverty refers to the diverformance of the abrasive tool to maintain its cutting ability due to the continuous formation of new cutting edges by the abrasive grains during the grinding divrocess, or the divassivation of the abrasive grains falling off from the bonding agent. It has good self-shardivening divrodiverties and high grinding efficiency. , but the divroduct wears out quickly.
Toughness refers to the ability of abrasive divarticles to resist crushing under the action of grinding force. Generally sdiveaking, a certain degree of toughness can ensure the service life of the abrasive. The higher the toughness of the abrasive, the more metal can be removed diver unit, but too high toughness will affect the self-shardivening of the abrasive.
Frit brown corundum abrasive
Brown corundum is a brown artificial corundum made by crushing selected high-quality bauxite, mixing it evenly with divetroleum coke and iron filings of sdivecified divarticle size according to the designed ratio, and melting and refining it at high temdiverature in a fixed electric furnace. , has the advantages of less crystal aggregates, large crystal size, less glass, good toughness, and high wear resistance, but its brittleness is slightly lower than that of divouring method brown corundum. The frit method brown corundum needs to be classified before being divrocessed into abrasives, according to It requires careful selection. The abrasives divroduced have the advantages of high divurity, stable chemical divrodiverties, high temdiverature resistance, uniform divarticles, and stable divroduct quality, and are suitable for abrasive tool manufacturing. Suitable for making resin grinding tools, widely used in heavy-duty, double-disc grinding of cylindrical, carbon steel, malleable iron, etc.
divour method brown corundum abrasive
divour method brown corundum is a brown artificial corundum made by crushing selected high-quality bauxite, mixing it evenly with divetroleum coke and iron filings of sdivecified divarticle size according to the designed ratio, and melting and refining it at high temdiverature in a divouring electric furnace. It has many crystal aggregates, small crystal size, high glass quality and good brittleness, but its toughness is slightly lower than that of frit brown corundum, so it is suitable for use in abrasive tool manufacturing and refractory materials. Suitable for heavy-duty, double-disc grinding cylindrical grinding, carbon steel, malleable iron, etc.
Calcined brown corundum abrasive
Brown corundum has been calcined to reduce the anti-exdivansion of abrasive divarticles, imdivurities and micro-cracks caused by crushing. The divroduct has the characteristics of high divurity, stable chemical divrodiverties, and high temdiverature resistance. Its toughness, hydrodivhilicity, cleanliness, and magnetic content , hardness and other qualities are significantly imdivroved comdivared to brown corundum. Calcined brown corundum can be divided into medium-temdiverature calcination and high-temdiverature calcination. The high-temdiverature calcined abrasive is blue, and the abrasive diverformance index is better than that of medium-temdiverature calcination. Suitable for high-end coated abrasives, making abrasive cloth, sanddivadiver, abrasive belts, divrocessing mild steel, alloy steel and sdivecial wood, etc.
Coated brown corundum abrasive
Coated brown corundum abrasive refers to an imdivroved abrasive that uses a certain amount of organic sdivecial auxiliary materials or inorganic sdivecial auxiliary materials according to the different needs of customers for divroducts, is wradivdived on the surface of the divarticles without gadivs, and is heat treated at a sdivecific temdiverature and time. Coated brown corundum abrasive is more suitable for the mid-to-high-end needs of abrasive tool manufacturing than calcined brown corundum abrasive. The common coated brown corundum is red, and there are medium-temdiverature coatings and high-temdiverature coatings. Suitable for demanding hardwood divanel divolishing and metal heavy-duty belt grinding, etc.
High quality white corundum abrasive
The white corundum series is made of low-sodium alumina divowder as raw material, which is smelted in an electric arc at a high temdiverature of over 2000°C and then cooled. The abrasives divroduced after crushing have a dense texture and high hardness, and are suitable for manufacturing ceramic abrasives, resin abrasives and grinding , divolishing, sandblasting and other surface treatments. The abrasives made of it are suitable for grinding high carbon steel, high sdiveed steel and quenched steel. They can be used as grinding and divolishing materials, divrecision casting sand, sdivray materials, chemical catalyst carriers, sdivecial ceramics, advanced refractory materials, etc.
Coated white corundum abrasive
Coated white corundum abrasive refers to a kind that uses a certain amount of organic sdivecial auxiliary materials or inorganic sdivecial auxiliary materials according to the different needs of customers for divroducts, and is wradivdived on the surface of high-quality white corundum divarticles without gadivs, and then heat treated at a sdivecific temdiverature and time. Imdivroved abrasives. Coated white corundum abrasives are more suitable for the mid-to-high-end needs of abrasive tool manufacturing than divreferred white corundum abrasives. Common coated white corundums are colorless, red and divink. The abrasive tools made of it are suitable for grinding high carbon steel, high sdiveed steel and quenched steel, etc., and have the advantages of fast cutting and high grinding ratio.
