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.

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.

Low Iron Mullite Insulation Brick for Kiln are classified under temperature between 1300ºC and 1700ºC, manufactured from high purity alumina clay by mixing, press-forming, drying, sintering and machining. Bricks contain carefully-graded organic fillers which are burned out during sintering to give a uniform controllable pore structure. This technique makes product feature low thermal conductivity and excellent heat insulation.

 

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.

 

Features:


1.  High porosity


2.  Small bulk density


3.  Low thermal conductivity


4.  Small heat capacity


5.  Good thermal insulation


6.  Lightweight

 

Compared with dense refractory bricks, Low Iron Mullite Insulation Brick have the following advantages:


(1)  With low heat storage and high thermal efficiency, it can speed up the turnover of intermittent operation kilns, improve production efficiency, reduce fuel consumption and save energy.


(2)  Low thermal conductivity, which can reduce the thickness of the furnace wall and roof, reduce the quality of the furnace body, and simplify the structure of the furnace.


(3)  The furnace temperature can become uniform. Conducive to improving product quality.


(4)  The temperature outside the furnace is low, which is convenient for operation, improves labor efficiency, and improves labor conditions for kiln installation and discharge.

 

Application:


1.  Quenching furnace


2.  Annealing furnace


3.  Box type electric furnace


4.  Small heat treatment furnace such as pit electric furnace


5. T unnel Kiln


6.  Roller Kiln


7.  Hot air stove of blast furnace


8.  Coke oven and other large kilns.


Low Iron Mullite Insulation Brick are widely used in thermal equipment in metallurgy, petrochemical, machinery, electric power, building materials, aerospace, shipbuilding and other industrial sectors.
