Description

Alumina Bubble Brick Introduce

Alumina bubble bricks are made of alumina hollow balls and alumina powder as the main raw materials, combined with other binding agents, and fired at a high temperature of 1750 degrees.It is a kind of ultra-high temperature energy-saving insulation material.Alumina hollow ball bricks have a maximum service temperature of 1800°C and have the advantages of high mechanical strength and low volume density.

Product name Alumina bubble brick
Operating temperature 1750 degrees
Main raw materials Alumina hollow ball material
Properties ultra-high temperature, energy saving, thermal insulation
Features Save materials, save energy

Application

Application of Alumina Bubble Brick

Alumina bubble brick can be used in high-temperature energy-saving (>30%) inverted flame kilns, shuttle kilns, molybdenum wire furnaces, tungsten rod furnaces, induction furnaces, nitriding furnaces, etc. It will achieve obvious results in reducing the weight of the furnace body, transforming the structure, saving materials and saving energy.
