Introduction:
Refractory products with alumina content greater than 75% and corundum as the main crystal phase. Very high normal temperature compressive strength (up to 340MPa). High load softening start temperature (more than 1700°C). Very good chemical stability, strong resistance to acidic or alkaline slag, metal and glass liquid. Thermal shock stability is related to its structure.

The corrosion resistance of compact products is good, but thermal shock stability is poor. There are two types of sintered corundum bricks and fused corundum bricks.

Sintered alumina and fused corundum can be used as raw materials, or bauxite clinker with high Al2O3/SiO2 ratio can be combined with sintered alumina and made by sintering method. Phosphoric acid or other binders can also be used to make non-fired corundum bricks.

Load softening temperature
Since the high aluminum has a high Al2O3 content, a low impurity content, and a low formation of the molten glass body, the fire-resistant softening temperature is higher than that of the refractory clay brick. However, since the mullite crystal has not yet formed a network structure, the load softening temperature is lower than the load softening temperature of the silica brick.

 

Advantage:

 

1.High load softening start temperature

2.Very good chemical stability

3. strong resistance to acidic or alkaline slag

 

Applocation:

    Mainly used in iron-making blast furnaces and blast furnace hot-blast furnaces, refining furnaces outside steel-making furnaces, sliding water heaters, glass melting furnaces, and petrochemical industrial furnaces

    Used in the iron and steel industry, the service life of chromium corundum material is more than double that of corundum material, such as ladle breathable bricks, etc.; used in the non-ferrous smelting industry, the wear resistance and erosion resistance of corundum bricks are significantly better than other brick types; In the black industry, using corundum bricks doubles the life span of corundum bricks used under the same conditions. The AK-type chromium corundum brick produced is used in the carbon black reactor of the carbon black factory, and the service life has exceeded the corundum brick.
    In the petrochemical industry, due to long-term high temperature (1350 ~ 1450 ℃), high pressure (3.1 ~8.53 MPa), strong reducing atmosphere (CO + H2 + CH4) and gas flow velocity in the gasifier of large and medium fertilizer plants Large (about 10 m·s-1), the corrosion and damage to the furnace lining refractories are serious, so the requirements for the furnace lining refractories are higher. High-performance corundum bricks have high density and strength, and are more resistant to air flow and wear resistance than corundum bricks. The introduction of Cr2O3 into the corundum bricks changes the internal quality of the products, and significantly improves the resistance to slag erosion and permeability of the bricks. The use of corundum bricks in the gasifier can increase the service life of the gasifier
