Cheap Brown Fused Alumina Manufacturer Chile

The brown corundum belongs to the ore material. The hardness of the ore material is usually indicated by the Mohs hardness. The Mohs hardness of the first grade brown corundum is between 9.0-9.3, and the micro hardness of the brown corundum is 2000-2200 kg / m ㎡. Other grades of brown alumina grit have different hardness according to the high and low alumina content.

Brown corundum, also known as carborundum, is a brown artificial corundum made of bauxite, coke (or anthracite) and iron filings after melting and recovering in an electric furnace with a temperature of more than 2000 degrees. It can be used for making ceramics, resin high consolidation abrasive tools, grinding, polishing, sandblasting, fine casting, etc., and silicon carbide price also for making high-grade refractory materials.(cheap brown fused alumina manufacturer chile)

The main component of the grade of brown fused alumina is alumina, and the aluminum content is used to differentiate the grades. Primary use of brown corundum: brown corundum is mainly used for abrasive Abrasives, high standard wear-resistant floor, water filtration, etc. Brown corundum is not new to all of us. It is the main raw material for producing high-temperature green carborundum refractory materials, abrasives and sandblasting.

(cheap brown fused alumina manufacturer chile)I estimate that after the smelting of brown corundum, many brown aluminum oxide factories have not carried out detailed analysis and comparison, as well as statistics and summary of data, that is to say, the chemical composition indexes of various parts of fixed furnace and dump furnace silicon carbide companies have not been analyzed and summarized with respect to structural characteristics and characteristics.

The lower the aluminum content, the lower the hardness. When the white corundum temperature is 2600 ℃, the resistance is close to the resistance at room temperature, and then it tends to increase with the temperature. However, when grinding materials with high thermal sensitivity, the width of the wheel should be appropriately reduced to avoid the burn and crack on the surface of the workpiece. When the temperature is low, the aluminum oxide abrasive resistance decreases. 

(cheap brown fused alumina manufacturer chile)There are two main production methods of white alumina: fixed furnace brown corundum and dumping furnace brown corundum. As a well-known Abrasives enterprise in China, I would like to share with you today the performance physical and chemical indexes and data report analysis of various parts of the aluminum oxide grit of the dumping furnace and the fixed furnace for your reference.

Color of brown corundum: brown corundum is brown, and the third grade black corundum is commonly known as black corundum. In addition, under the condition that the rigidity and power of the machine tool are allowed, such as selecting a wide wheel, the productivity can also be improved and the roughness can be reduced. The aluminum oxide abrasive blasting grit we usually use is obtained by electric melting.(cheap brown fused alumina manufacturer chile)

The conductivity of emery is different at different temperature, pink corundum which is opposite to the resistance temperature of metal in a certain temperature range. The change of resistivity of high purity silicon carbide with temperature. The relationship between resistivity and temperature of industrial synthetic corundum price is more complicated. When the temperature is about 1500 ℃, the resistance begins to increase gradually.
