High Alumina Castable

High Alumina Castable
(1) The bulk density is small, and the anticorrosion and penetration of the lining anti-slag should be strong.
(2) Excellent thermal shock resistance, good resistance to rapid cooling or large temperature changes.
(3) High compressive strength and high stability of the high temperature lining.
(4) The use of high temperature can reach 1400-1550 °C
(5) Acid-resistant slag or solution chemical attack.

Brief Description Of High Alumina Castable

The high-alumina castables are made of high-alumina bauxite aggregate as the main raw material, and according to the proportions of different granules, calcium aluminate cement binders and admixtures are added to mix the bulk cast refractory castables. It can be used directly after adding water and stirred, and are molded by vibration casting. High-aluminum castable is also called high-aluminum low-cement castable. It is easy to construct. It can be cast directly on the industrial furnace to form an integral lining, or it can be premade into refractory prefabricated blocks and used in masonry in the industrial furnace.

Application Of High Alumina Castable

High-aluminum castables are suitable for heating furnaces, soaking furnaces, heat treatment furnaces, rotary kiln; various high-temperature burner linings, heating furnace pipe packing linings, steel furnace scouring device components and petrochemical catalytic cracking reactor High-temperature wear-resistant lining; blast furnace iron channel, iron furnace iron trough, hot metal pretreatment with the overall dust gun and other lining. It can also be used to make large prefabricated blocks and linings.
