Product Description

The main mineral composition of chrome corundum brick is prun-Al2o3-cr2o3 solid solution.The secondary mineral composition is a small amount of composite spinel (or non-composite spinel), and the content of chromium oxide is 1% ~ 30% of firebrick.There are two types of fused cast chrome corundum brick and sintered chrome corundum brick.Chrome corundum brick in general refers to sintered chrome corundum brick.

α-Al2O3 was taken as the raw material, and a moderate amount of chromic oxide powder and fine powder of chrome corundum clinker were added.The content of chromic oxide in sintered chrome brick is generally lower than that of fused cast chrome corundum brick.Moreover, the gray-pouring method can be used to prepare the gray-Al2o3 powder and chromium-oxide powder, and the grain-Al2o3 powder can be mixed uniformly, and the grout can be made by adding degumming agent and organic binder, and some chrome-corundum clinker can be added at the same time.It can be used as lining of glass kiln, screwing glass liquid flow hole cover plate brick, as backing lining of iron water pretreatment device, waste incinerator, coal water slurry pressurized gasifier, etc.

At present, the application of chrome corundum brick has more extensive application, a kind of chrome corundum brick is made from metal chrome slag as the main raw material, this product is widely used in zinc smelting electric furnace, volatile kiln, chrome corundum brick has excellent thermal vibration stability and high temperature creep performance, simultaneously conforms to the requirements of national circulation economy.

Performance and application of chrome corundum brick

Chrome corundum brick is made from pure Al2O3 and Cr2O3 as the main raw materials. Compared with ordinary pure corundum brick, it has better properties, such as fire resistance, weight softening deformation temperature, bending strength, high temperature creep, high temperature volume stability and slag corrosion resistance.

1. Properties of sintered chrome corundum brick

The research and development of chrome corundum began in 1989, and has been put into production and widely spread.Chrome corundum bricks are used in high temperature gasifier and carbon black reactor with good effect, especially in the throat of large carbon black reactor, the effect is better than pure corundum bricks.In recent years, we have studied chrome corundum bricks with different contents of Cr2O3, and basically found out the effect of Cr2O3 content on product performance, and determined the role of the binding agent in the product.

2.Application of chrome corundum brick

In recent years, chrome corundum bricks are mainly used in high temperature kilns such as synthetic ammonia gasifier and carbon black reactor.The throat pipe of a carbon black reactor furnace introduced by a carbon black factory was replaced by chrome-corundum brick of our hospital, which was used for more than 4 months. The furnace stopped for inspection and the inner diameter was maintained well. No melting or cracking was found.At present, the service life of furnace lining can reach 10~15 months.
