Audited Supplier Product Description Of High Alumina Brick:
High alumina brick is one kind of neutral refractory material, where safe working temperature is more than 1300 degree centigrade. not only has certain corrosion resistance to acidic and alkaline slag, but also has the characteristics of high cold crushing strength, erosion resistance, strong penetration resistance, and high refractoriness under load.
it is usually divided into three grades: Grade I--Al2O3 content>75%; Grade II--Al2O3 content is 60~75%; Grade III--Al2O3 content is 48~60%.
We offer High Alumina Bricks in different specifications as per customer requirements.
Application of High Alumina Brick:
1.Iron & steel making industry: Blast furnace,hot blast stove,electric furnace,ladle,tundish,heating furnace,refining furnace,reheating furnace,annealing furnace,cupola furnace.
2.Non-ferrous Metal industry:Smelting furnace,refining furnace,reverberatory furnace,converter furnace.
3.Building materials industry:Cement kiln,glass kiln,ceramic kiln,lime kilns,kiln car,tunnel kiln.
4.Energy & Incineration:Coke oven,circulating fluidized bed boiler,carbon roasting furnace, incinerators.
5.Others:Petrochemical industry furnace.
Feature of High Alumina Brick:
1.Excellent strength at ambient and elevated temperatures.
2.High compressive strength.
3.Very low levels of iron and other impurities.
4.Lightweight and energy-efficient.
5.Lower heat storage than denser refractory.
6.Heats quickly and economically to operating temperature.
Dimensions of High Alumina Brick:
The standard size of it is 230*114*65mm; and 230*114*76mm, 230*114*32mm, etc are also common used. Except for the common sizes, some special shapes could be customized according to the customers' requirements
