Mingzhu has three 5000KVA corundum dumping furnaces and one 5000KVA shelling furnace with an annual production of 50000 tons. Its products are exported to Europe, Japan, Russia, and other countries, and they enjoy a good reputation.
Sanmenxia is located in the west of Henan province, Luoyang in the east, Nanyang in the south, and bordering Shanxi province in the west with convenient transportation. Mingzhu abrasives sell well both domestically and overseas because they comply with ISO quality system standards and maintain high-quality products all the time.
Brown fused alumina is made by fusing and purifying in a pouring electric arc furnace at a temperature of over 2200° C with high-quality bauxite, carbon material, and iron filings as the main materials. Finally, a variety of particle sizes of products are made by purifying, crystallization, sorting, crushing, magnetic separation and screening, washing and acid washing, etc. Brown fused alumina have the characteristics of high purity, good crystallization, strong liquidity, low linear expansion coefficient, corrosion resistant, good self-sharpening, strong grinding force, and the characteristics of high refractoriness.
In the brown fused alumina industry, Mingzhu abrasives' production and quality are stable all the time. It now has three 5000KVA corundum dumping furnaces and one 5000KVA shelling furnace with an annual production of 50000 tons.
The available size of brown fused alumina used for bonded abrasives is F20–F200. The available size of section sand is 0-1mm, 1-3mm, 3-5mm, 5-8mm, 10-20mm, which can also be customized, such as 0-0.5mm, 0.15-0.5mm, 0.5-1mm, 8-15mm, etc.
The abrasives that are made of it are suitable for metals with high tensile strength, such as all kinds of general steels, malleable cast iron, hard bronze, etc.
(1)Due to high temperature, corrosion resistance, high strength, and other properties, it can smelt rare metals, special alloys, and ceramics; blast furnace lining (walls and tubes), physical and chemical containers; spark; and heat anti-oxidation coating.
(2)Due to the hardness, wear resistance, and high strength characteristics in chemical systems, it can be used as a variety of reaction vessel and piping as well as chemical pump parts; it can also be used as mechanical parts, all kinds of abrasives, such as extrusion die nozzle pencil, etc. What's more, it can be used as tools, dies abrasive, bulletproof material, human joints, and sealing ring mold.
(3)Corundum insulation materials, such as lightweight corundum bricks, corundum hollow spheres, and fiber products, are widely used in various walls and the roof of high-temperature kiln furnaces.
"Continuous innovation, striving for excellence" is Mingzhu's goal. Its products are exported to Europe, Japan, Russia, and other countries, and they enjoy a good reputation. Mingzhu is a good corundum manufacturer. Mingzhu brown fused alumina is your best choice.
