Light Weight Insulating Castable DYSLW

Nov 15, 2023

Lightweight insulation castables are composed of high-quality, high-strength materials, aggregates and ultra-fine powders, and composite additives. It has the advantages of high refractoriness, high strength and low thermal conductivity. The thermal insulation castable of the present invention has the characteristics of low thermal conductivity and small volume density, which can reduce the heat and thermal energy consumption of industrial kilns and reduce the weight of the furnace lining. Among high-temperature lightweight castables, the raw materials for high-temperature lightweight castables that can be used above 1200°C are porous materials, porous clinkers such as mullite, corundum, high alumina, siliceous and magnesium oxide, or lightweight bricks. This castable can be directly used in the lining of atmosphere furnaces at 1350°C.

Product features:

1: High temperature resistance and high strength.

2: Low thermal conductivity.

3: Small volume density, reducing kiln heat consumption.

4: Convenient construction and reduced labor intensity.

5: Lightweight, reducing the weight of the kiln lining.

 

Lightweight insulation castables are divided into three types according to temperature:

1: Low temperature insulation castable, generally below 800°C.

2: Medium temperature insulation castable, generally below 900-1100°C.

3: High temperature insulation castable, generally below 1200-1350°C.

 

Mullite polyhydrogen bricks can be directly used on kiln working surfaces above 1300°C.
