55% - 82% Al2o3 High Alumina Refractory Bricks For Pellet Shaft Furnace

 

Description

 

The high alumina brick is an alumina-silicate refractory material in which the Al2O3 content is more than 55%, and is calcined from a high-content alumina raw material such as a silicone raw material or a bauxite. High heat resistance and high temperature resistance at 1770 ° C and above. Has good slag resistance, mainly used in the masonry of steelmaking electric furnace, glass furnace, cement rotary furnace and so on.

 

Characteristics of high alumina bricks:

 

1. Refractoriness
More refractory than refractory clay bricks and semi-silica bricks, up to 1750-1790C, belonging to high-grade refractory materials.

 

2. 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.

 

Features:

 

Mechanical strength

Excellent load-bearing properties

High temperature

Excellent resistance to spalling

Resistant to corrosion

 

Application:

1. Iron & steel making industry: Blast furnace, hot blast furnace(stove), pellet shaft furnace, hot metal ladle, steel ladle, tundish, heating furnace, soaking pit furnace, heat treatment furnace, refining furnace, reheating furnace, metal mixter furnace, annealing furnace, cupola furnace, electric arc furnace, induction furnace, AOD furnace, VOD furnace,etc thermal technology equipment.
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, general boiler, power generation, boiler, circulating fluidized bed boiler, electric furnace, carbon rosating furnace, waste incinerators.
5. Others: Petrochemical industry furnace.
