Black Aluminum Oxide Blast Media Manufacturers Czech

The production method of black aluminum oxide media is the same as that of black silicon carbide, but the raw material used has a high purity requirement, and it is also formed at a high temperature of about 2200 ° C in a resistance furnace. It is green, translucent and hexagonal. Its silicon carbide content is higher than that of black. 100 grit aluminum oxide media deoxidizer can also be used as deoxidizer for steel-making and modifier for cast iron structure.

Its physical properties are similar to that of black silicon carbide, but its properties are slightly more brittle than that of black silicon carbide, and it also has better thermal conductivity and semiconductor properties. Its hardness is between brown corundum and diamond, and its mechanical strength is higher than that of pink corundum. black silicon carbide contains about 95% SiC, and its toughness is higher than green silicon carbide.

It is mostly used to process materials with low tensile strength, such as glass, ceramics, stone, brown fused alumina refractory, cast iron and non-ferrous metals. Green silicon carbide contains more than 97% SiC and has good self sharpening property. It is mostly used to process cemented carbide, titanium alloy and optical glass, as well as honing cylinder sleeve and high-speed steel tools. In addition, there is cubic silicon carbide abrasive, which is a yellow green crystal made by a special process.

The brown aluminum oxide surface roughness can be processed from ra32-0.16 μ m once to ra0.04-0.02 μ m once. It can be used as abrasives to make all kinds of abrasives, such as grinding wheel, grindstone, etc. it has strong wear resistance, can complete the grinding of hard materials, and increase the service life of abrasives. Due to its high temperature resistance, aluminum oxide abrasive is also one of the ideal materials for solar water heaters in expressways and airstrips.

The abrasives are suitable for super finishing of bearings. As a deoxidizer and high temperature resistant material in smelting, brown aluminium oxide has good corrosion resistance, high temperature resistance, good thermal conductivity and strong impact resistance. We use aluminum oxide grit to make various smelting furnace linings, high temperature furnace components, supports, crucibles, etc., which can be used to smelt all kinds of ultra-high temperature materials.

In addition, it is used as high temperature indirect heating materials in non-ferrous metal smelting industry Materials, brown fused alumina price such as vertical retort, aluminum electrolytic cell, copper melting furnace lining, etc. Black silicon carbide is made of quartz sand, petroleum coke and high quality silica by high temperature smelting in resistance furnace. Its hardness is between synthetic corundum and diamond, and its mechanical strength is higher than that of brown corundum.

Application and characteristics of silicon carbide: white alumina deoxidizer is a new strong Compound Deoxidizer, which replaces the traditional silicon powder and carbon powder for deoxidization. Compared with the original process, it has more stable physical and chemical properties, good deoxidation effect, shortened deoxidization time, saved energy, emery abrasive improved steel-making efficiency, improved steel quality, and improved environment Protection.
