good job and nice quality! Hope our next business

—— Carsten Schmickler

very nice company.waiting for my next visit

—— Neetu Arora

good quality, but price is higher than other supplier.

—— Bipin Vagal

thank you for your products and service. During the project, the staff from your company cooperated with our side perfectly. The goods are all follow our order. The after-sale service also good.

Cement Kiln Mullite Insulation Brick

 

Low Iron Mullite Insulation Brick refers to a heat-insulating refractory product made of bauxite with an Al2O3 content of not less than 48%.

Low Iron Mullite Insulation Brick are mainly made of bauxite clinker, combined with clay as raw materials, mixed with binders and sawdust.

 

In order to improve product performance, industrial alumina, corundum, sillimanite, kyanite, and silica are added The powder can be produced with bulk density above 0.4g/cm3. Al2O3 content and bulk density are different, the highest operating temperature is also different, usually 1250-1350 ℃, some up to 1550 ℃

 

Production process:


Low Iron Mullite Insulation Brick includes five parts: preparation of foaming agent, preparation of foam slurry, molding, drying and firing.


(1) Preparation of foaming agent.


(2) Modulation of foam mud.


(3) Forming.


(4) Dry.


(5) Firing.

 

The bulk density of GM series 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.

 

Features Of Insulating 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 Insulating 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 Insulating Brick

  • Alumina contents range from 40% to 80%
  • Widely used throughout metallurgical industry
