High Heat Alumina Silica Firebrick Insulation For Coke Oven

 

Definition:

High Heat Alumina Silica Firebrick Insulation For Coke Oven have the characteristics of low thermal conductivity, high load softening temperature, small residual expansion, and excellent reburning line change performance. They are suitable for industrial furnaces such as coke ovens, hot blast furnaces, glass furnaces and carbon furnaces. It is mainly used for the heat insulation layer and working layer of thermal equipment, and can be used for the heat insulation layer of various high temperature kiln equipment under high temperature conditions (≤1500℃) without contact with molten slag. This product is suitable for the heat insulation material of the silica brick lining of the high temperature hot blast stove of the large blast furnace and the heat insulation of the silica brick masonry of the glass furnace.

 

General Insulating High Heat Alumina Silica Firebrick Insulation For Coke Oven can be divided into two levels: the first grade can be used in the top of the steel rolling heating furnace and the roof of the silicate industrial kiln, and can be directly in contact with the flame; the second grade is used in the general industrial kiln Insulation. Applicable to: industrial furnaces such as coke ovens, hot blast furnaces, glass melting furnaces and carbon calciners. Generally, the bulk density of silicon heat insulation refractory bricks is 0.9-1.1g/cm3, the compressive strength is 2.0-5.9MPa, and the thermal conductivity is 0.35-0.42W/(m·K). It has excellent fire resistance, its softening temperature under load is close to 1620℃ for dense silica bricks, with only a small residual expansion, and its thermal stability is better than dense silica bricks. Therefore, siliceous heat-insulating refractory bricks can be used for a long time under high temperature conditions (1500-1550°C) without contact with molten slag, but they are especially suitable for high-temperature hot-blast furnaces of large blast furnaces. Thermal insulation of silica brick gas.

 

Advantage:

 

1. Light weight

2. Low density

3. High strength,good thermal shock resistance

4. Low heat storage, low thermal conductivity

5. Saving energy

6. Precise size

7. Good thermal insulation effect

8. Good quality and low price

 

Application:

 

It is widely used as a primary hot face refractory lining or as back-up insulation behind other refractory in furnace(such as carbon furnace, cracking furnace, heating furnace for oil refining, roller kiln, tunnel kiln.), flues, refining vessels, heaters, regenerators and similar high temperature industrial equipment.
