Product Description
Insulating Firebrick:
Insulating Firebrick is an aluminium silicate type of insulating firebrick with light weight has high mini-porosity arranged in average, keep furnace wall low radiation and depress the charges of fuels. Light weight means the lowest thermal storage, it's quicker to heat and cool, and permit rapid cycle work. They are used for 1260C-1550C, you can choose the most economical products according to service temperature. Light Weight Insulating Firebrick is in accordance with ASTM Standard.

| Characteristic: | Application: |
| Low thermal conductivity: Gives good thermal insulation, enabling the use of thin-walled constructions. | Hot face lining and Back up insulation |
| Low heat storage: Due their light weight, coupled with low thermal conductivity, the TJM bricks absorb minimal heat, giving significant energy savings in cyclicly operated kilns. | Roller kiln, tunnel kiln, shuttle kiln, top hat kiln of ceramics industry, various resistor furnaces |
| Purity: The low iron and alkali flux content confers good refractoriness and the high alumina content contributes to their stability in reducing atmospheres. | Reducing atmosphere furnace |
| High cold crushing strength and low thermal conductivity properties | gas producer of chemical industry |
| Accurate dimensions: Enable the bricks to be laid more efficiently, with thin, uniform joints, allowing the construction of strong and stable structures. | Lining of high-temperature kilns of industrial ceramics, industrial furnaces under 1650C of petrochemical, machinery industries |
| Special dimension and shapes can be produced | Hot-air furnace, heating furnace, soaking furnace, heat treatment furnace of metallurgy industry |
