Types Of Corundum Brick

Sintered corundum bricks manufacturer

Ordinary Corundum Brick

Corundum bricks are refractory products with alumina content greater than 90% and corundum as the main crystal phase. Normal temperature compressive strength (up to 340MPa) is high, load softening start temperature (more than 1700 ℃), good chemical stability, acidic or alkaline slag, metal and glass liquids have strong resistance.
This corundum brick is widely used in petrochemical and fertilizer industry cracking, konverta forno, the metallurgical industry, and other high-temperature kiln lining, and kiln furniture. Ironmaking blast furnaces and blast furnaces hot blast furnaces, steelmaking furnaces outside the refining furnace, sliding water apparatus, glass melting kilns and petrochemical industry furnaces, and so on.

Lightweight Corundum Brick

Lightweight Corundum Brick

Lightweight corundum brick is also known as alumina insulation brick, foam corundum brick, or foam alumina brick. It contains more than 90% alumino, mainly composed of corundum lightweight refractory materials. The refractoriness is high, and the volume shrinkage of refiring is small. Compressive strength 4~25MPa, bulk density 0.8~1.35g/cm3. malalta varmokondukteco. Good thermal shock resistance.
Lightweight corundum bricks can be used for the thermal insulation layer of thermal equipment, or thermal equipment lining with the direct action of the flame, but should not be used for the slag direct erosion. The maximum operating temperature is generally up to 1650℃, and products with high purity can reach 1800℃.

Chrome corundum brick for sale

Chrome Corundum Brick

Chrome corundum bricks are corundum refractory products containing Cr2O3. At high temperatures, Cr2O3 and Al2O3 form a continuous solid solution, so the high-temperature performance of chrome corundum products is better than pure corundum products. It has a tough texture, dense structure, and high strength. Chromium corundum bricks have the advantages of high refractoriness, alta forto, good thermal shock stability performance, and strong erosion resistance. It is resistant to scouring, touch damage, erosion, and spalling in use.
It has good use in metallurgy, vitro, petrolkemiaj, and environmental protection hazardous waste disposal industry.

Electrofused Corundum Bricks

Electrofused Corundum Bricks

Al2O3 content in α-βAl2O3 electrofused bricks is ≥94%, and its crystalline phase structure is composed of 45~55% α-Al2O3 phase and 45~60% β-Al2O3 phase. Its load-softening temperature is ≥1750℃. Its density is 3.38 al 3.39 g/cm3, of which electrofused α-βAl2O3 bricks are very good bricks for floating glass melting kilns used in the working part of the wall part of the cross-passage pool. For large kilns, it is mainly used in the working section, cross-pass, and branch-pass.

Corundum mullite bricks manufacturer

Korundaj Mullite Brikoj

Corundum-mullite bricks are high-alumina refractory products composed of corundum and mullite main crystal phases. The physical and chemical properties of corundum-mullite brick are as follows: Al2O3>85%, Fe2O3 0.45%, ŝajna poreco 19%, room temperature compressive strength greater than 55MPa loaded softening temperature greater than 1700℃, heating line change (1600℃, 3h)-0.1%, thermal shock resistance (1100℃ water-cooled) greater than 30 fojojn. It has good high-temperature strength, high-temperature creep resistance, thermal shock resistance, kaj eroziorezisto.
Corundum mullite bricks are mainly used in harsh industrial environments such as high temperature, high pressure, high speed, and corrosion. This includes the lining of sintering furnaces, heating furnaces, and other equipment and the manufacture of sintered bricks in metallurgical, chemical, and electric power industries.

Performance Index of Corundum Brick

firebricks shipment

The raw material used in corundum bricks is a solid solution synthesized by melting alumina and chromium oxide at a certain ratio. The use of a special refractory production process to make refractory bricks, can improve and enhance the intrinsic quality of the products, and improve the high-temperature performance of the products.
The physical and chemical performance indexes of some high-performance corundum bricks developed and produced by PER Refractories Factory have reached the performance indexes of some similar products and corundum bricks in foreign countries. Our corundum bricks have been widely used as lining materials in petrochemical thermal installations which are characterized by high temperature, high pressure, kemia erozio, and severe mechanical abrasion.
With the progress of production technology in the petrochemical industry, many new techniques and technologies have been adopted in production, to make the equipment achieve the purpose of large load, long cycle, malalta energikonsumo, and low cost.
The corundum bricks produced and supplied by PER Firebricks company are mainly used in ironmaking blast furnaces and blast furnaces hot blast furnaces, refining furnaces outside the steelmaking furnace, sliding water apparatus, glass melting kilns, and petrochemical industry furnace.

Application Scenarios of Corundum Brick

In the steel industry, the service life of chrome corundum bricks is more than double that of corundum bricks, such as ladle air-permeable bricks.
In the non-ferrous smelting industry, corundum bricks are significantly better than other bricks in terms of wear resistance and erosion resistance.
In the carbon black industry, the life span of corundum bricks is twice as long as that of corundum bricks used under the same conditions.
The AK-type chrome corundum bricks are used in the carbon black reactor of the carbon black factory, and their service life has exceeded that of corundum bricks.

In the petrochemical industry, large and medium-sized fertilizer plant gasifiers due to long-term high temperature (1350 ~ 1450 ℃), high pressure (3.1 ~ 8.53 MPa), a strong reducing atmosphere (CO + H2 + CH4), and the gas velocity (about 10 ms-1).
The erosion and damage to the furnace lining refractories are more 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 gas scouring and abrasion than corundum bricks.
The introduction of Cr2O3 in corundum bricks changes the intrinsic quality of the product, making the brick’s resistance to slag erosion and permeability significantly improved. The use of corundum bricks in gasifiers can improve the service life of gasifiers.
