High Chrome Brick Details

High chrome bricks are made of chromium oxide and alumina as the main raw materials, or introduce a small amount of zirconia, and the chromium oxide content is not less than 75% after high temperature firing, and the content of chromium oxide, alumina and zirconia is not less than 98% Shaped refractory products. Chromium oxide products generally produced with industrial pure chromium green as the main raw material

Features

It has excellent corrosion resistance, high compressive strength at room temperature, high high temperature strength, excellent wear resistance, high refractoriness, excellent thermal shock resistance, and good high temperature volume stability.

Application

Widely used in coal gasifier lining materials and coal water slurry pressurized gasifier working face lining.

In the past, high chromium refractory products were mainly used in reinforced glass furnaces, and a small amount of them were used in insulating glass tank furnaces. Now high chrome bricks are increasingly being used in some soda lime glass tank furnaces. Their main uses are not limited to all Part of the liquid hole, but also used for the end wall and to a limited extent used for the corner bricks of the feed opening. For their composition, they have the potential for coloring, so that high chromium products are usually very "white" The glass is not compatible. Earlier, this product was mainly used for colored glass, but now high chromium products have also been successfully used in transparent container glass furnaces. The number of high chromium products used in glass melting furnaces Much depends on the design of the flow hole, the cooling of the flow hole, the daily output of the tank furnace, and the operation of the furnace. A glass manufacturer may use high chrome bricks for all cover plates and add melting The end wall of the pool. Its masonry flow hole provides the potential to increase the life of the furnace, because the corrosion resistance of this material to most glass is at least twice as strong as that of molten AZS brick.
