Black Aluminum Oxide Media Wholesale Supplier

Today, we will learn that black corundum is made of high-quality bauxite as the main raw material, adding less reductant and smelting at high temperature in the electric arc furnace, with black color, The hardness is moderate, the toughness is large, the wear-resistant edges and corners are sharp, the self sharpening is strong, the grinding heat is small, the polishing workpiece cleanliness is high, the basic material of black corundum abrasives is concentrated, the cutting force is strong, the toughness is large, the hardness and softness are integrated, the wear resistance is good, and the work efficiency is high.

The technological process of black corundum is as follows: corundum block - coarse crushing - medium crushing - crushing - segmented screening - magnetic separation - fine screening - Inspection - packaging Black corundum is mainly used for free grinding, such as bottom polishing before electroplating of metal parts, brown fused alumina products, polishing of bicycles, motorcycles, sewing machines, clock parts, lighting, plastics and hardware tools, sandblasting (rust removal, glass spray), processing materials, manufacturing resin cutting pieces, angle grinding pieces and coated abrasives.


Smelting method of black corundum: Bauxite trihydrate is used as raw material, a small amount of reducing agent is added, and the power consumption is about two-thirds of that of brown corundum. The main chemical composition is: Al2O3 is not less than 77%, SiO2 content is 10-12%, Fe2O3 content is 7-10%, TiO2 is about 3% white aluminum oxide, and the proportion of production process of corundum is not less than 3.61. Black corundum is a common abrasive in our production and life. It is mainly used for stainless steel kitchenware, lamps and lanterns, motorcycle parts and so on.


Why is black corundum so popular? Mainly because of its unique use advantages: high hardness, toughness, good adhesion and hydrophilicity, less heat, strong self sharpening, high efficiency, high finish. The basic particles are concentrated, the white corundum cutting force is strong, the toughness is large, the hardness and flexibility are combined, the wear resistance is good, and the work efficiency is high. It is the most ideal product for grinding, polishing and sandblasting stainless steel products.


That is to say, each mass of sodium oxide consumes 18.10 parts of brown fused aluminum oxide and generates 19.10 parts of sodium aluminate. If a certain amount of silicon oxide is added to the melt to make the sodium oxide crystallize and precipitate as triclinite (Na2O · Al2O3 · 2SiO2), the sodium oxide of each molecule only consumes one molecule of alumina, that is, each mass of sodium oxide only consumes 1.645 parts of alumina, and 4.584 parts of triclinite are generated.


Rough polishing 2:1-3:1 medium fine polishing 3:1-5:1 medium polishing abrasive dssm120-240 m is used to remove small burr, flash, fine grain mark, etc. of metal and non-metal workpiece, which can process the work requiring medium polishing after rough polishing. There is no limit to the shape of the pink corundum abrasive tools with strong rigidity, and the size of the abrasive should be larger than the workpiece, which can improve the grinding efficiency and facilitate the separation DSSM ¢ 2.o1000m - ¢ 14 is mainly used for rough polishing, workpieces requiring fine polishing after medium polishing and surface finishing of one-time fine polishing.


In the introduction of the production process of black corundum, we have learned some unknown problems or knowledge, but we are still unfamiliar with the industry where the second Dagang grinding wheel factory of Yancheng city is located. The white aluminium oxide hardness is moderate, the toughness is large, the wear-resistant edges and corners are sharp, the self sharpening is strong, the heat generated in grinding is small, and the cleanliness of polishing workpiece is high.
