high strength fire clay insulation refractory bricks
Model Number:
Certification:
Minimum Order Quantity:
Light weight insulation fireclay brick is a kind of insulation material adopting organic matter as ignition loss substance in order to increase the porosity of refractory, which has such advantages as high porosity, small volume density, good insulation effect, high mechanical intensity, small thermal conductivity and long service life. For various industrial kilns & furnaces, it is a kind of essential refractory for energy saving and temperature preservation.
It is a kind of the light weight refractory products which contains the alumina content range from 20% to 48% .
Feature of Light weight insulation fireclay brick:
High refractoriness,High-temperature endurable .
Good corrosion resistance.
Good spalling resistance and wear resistance.
Good thermal shock resistance.
High mechanical strength.
High-temperature creep rate is low.
Good volume stability at high temperature.
Production Process of Light weight insulation fireclay brickbrick:Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packaging and Shipment
