According to the content of Al2O3, high alumina bricks are usually divided into three grades: Grade I──Al2O3 content>75%; Grade II──Al2O3 content is 60～75%; Grade III──Al2O3 content is 48～60%. -
Clay Insulation Brick
Fireclay insulation brick is made of local top grade fireclay materials with a content of 35%~42% Al2O3 according to the lasted national standard. The working temperature of them is from 1000-1200 ℃ and bulk density is 0.5-1.0 g/cm3.

High Alumina Insulation Brick
High alumina insulation brick refers to all lightweight bricks with AL2O3 more than 45%. It is made of bauxite and a small amount of clay. After grinding, it is poured into a slurry form by gas or foam. It burns at a temperature of 1300~1500°C. This kind of brick is not directly exposed to the high temperature in the kiln, but only has a thermal insulation layer near the kiln wall.

Acid Proof Brick
Fire-resistant and acid-resistant bricks are the main refractory materials used in acid regeneration roasting furnaces such as cold-rolled sheets and silicon steel wires in the steel-making system. Their performance directly affect the service life and economic benefits of the acid regeneration furnace.

Anchor Brick
In industrial design, when the thickness or load of the furnace body structure is large, or the ambient temperature is high, the refractory brick structure serves as the anchor in the lining. Anchor bricks, hanging bricks, and anchors are mainly used for anchoring castables . The main material of anchor bricks is alumina. Our factory can customize anchor bricks with various indexes and sizes.
