High Quality Light Weight Mullite Brick K23 Insulating Firebricks

Description For Refractory Heat Insulating Brick :

The bulk density of lightweight heat-insulating brick is 0.6~1.25g/cm3. Working temperatures range from 1300℃ to 1600℃ . Each grade of products has unique design to meet different thermal, physical and chemical demands.GM series lightweight heat-insulating bricks are made from good quality and super-pure raw materials, with strictly classified fillings according to their grades. These fillings can form a uniform pore structure after burnt during the process of manufacture.Each face of the brick is machined to the required accurate size.this material profitable by lessening fuel costs, construction costs and reducing the amount of time spent in the high temp furnace.

Mullite insulation bricks refractory material can be used in linings or heat-insulating

materials of the industries, such as, ethylene pyrolysis furnaces, tubular furnaces,

reforming furnaces of synthetic ammonia, gas generators and high-temperature shullte kilns, etc.

Features Of Light weight Mullite Brick

* Lower thermal conductivity

* Lower bulk density

* Light weight character

*Lower creep rate in high temp

* Good thermal shock resistance performance

* Higher temperate resistant with good refractoriness

Applications Of Light weight Mullite Brick

The refractory linings of hot surfaces or backing heat-insulating layers of other refractory materials. The refractory linings or heat-insulating materials of the industrial furnaces in the petroleum or chemical industries , such as , ethylene pyrolysis furnaces, tubular furnaces, reforming furnaces of synthetic ammonia, gas generators and high-temperature shuttle kilns, etc.

Specifications Of Light weight Mullite Brick

Alumina contents range from 40% to 80%

Widely used throughout metallurgical industry
