Refractory Calcined Bauxite for high alumina bricks
Model Number: hongtai
Minimum Order Quantity:
High-alumina raw Calcined bauxite: a neutral refractory with a alumina content of 48% or more.It is made from bauxite or other raw materials with high content of alumina by molding and calcining.Thermal stability, high refractoriness in more than 1770 ℃.Good slag resistance, lining for building steel furnace, glass furnace, cement rotary furnace, etc.
The high aluminum aggregate is divided into four grades according to the content of aluminum, the level 3 high aluminum content is not less than 55 percent, the level 2 high aluminum content is not less than 65, the level 1 high aluminum content is not less than 75, the level of the high aluminum content is more than 85.
Refractory aggregate can be divided into clay, high aluminum, rigid jade, silicon, magnesium, magnesia and alumina spinel refractory aggregate.
Refractory aggregate is a kind of refractory particle which plays a role of skeleton in the granularity composition of refractory.They are made by calcining, crushing, or artificial synthesis of various refractory materials with a particle size greater than O.Granular material of 088mm.Aggregate is the main material of amorphous refractories, generally accounting for 60% ~ 75% of the total composition.Therefore, the amorphous refractory material is generally named after the aggregate material used, such as high bauxite clinker as aggregate refractory castable or refractory ramming materials, known as high aluminum castable or high aluminum ramming materials.
