20% Apparent Porosity Sintered High Alumina Corundum/Mullite Refractory Bricks

sintered high alumina corundum/mullite refractory bricks

Corundum Bricks are high alumina refractory bricks are made for extreme demands. The alumina content in Corundum Bricks can be traced to the use of synthetic corundum of high purity, such as white fused alumina or tabular alumina. Additional ingredients are special refractory clays, reactive alumina and very pure modifications of silica.
Corundum Bricks are fired at high temperatures to form a matrix with mullite, mullite-corundum or corundum that has excellent volume stability.

The service temperature for Corundum Bricks goes up to 1800°C. Corundum Bricks can be used nearly all fields of industrial application where extreme high temperature and increased resistance against aggressive slags and atmospheres. Such properties or features of Corundum Bricks are necessary especially in the chemical industry and for the production of carbon black. The addition of chromium oxide, zirconium oxide and phosphates lends the bricks excellent structural flexibility, which is required for ash melting furnaces and gas reactors in incinerators.

2)Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packaging and Shipment.
2.Quality Assurance
1)Going out the furnace→checkout→packing→qualified product→putting in storage→sale,
2)The process from raw to product are strictly tested by equipment.
1.Inspection and Control of incoming raw materials: according to the chemical content,raw materials are classified into different levels to ensure quality of brick first.
2.Inspection and control of the process: during the production,every brick will be weighed twice strictly to reduce the error of weight .
3.Quality audit by quality management: inspection of product standardization of quality of each product by process control and experimentation, taking corrective measures timely whenever deviations are noted.
4.Before delivery, the inspectors will inspect the size,appearance, physical and chemical properties of brick again in factory.
