For Kiln, Furnace, Oven Building and Maintaince

Insulating Fire Bricks, also known as High Alumina Bricks ( IFB ), are high temperature, lightweight refractories which are used as insulation in kilns, forges and furnaces. Furnaces and kilns always require a combination of Light Fire Brick and Dense Fire Brick.

The high alumina products is in the high Al2O3, less impurities, the formation of fusible glass less, so the load softening temperature than the clay brick, but the mullite crystallization doesn’t  form a network organizations, therefore refractoriness under load is lower than silica bricks. 

 Light Weight Mullite Insulation Brick, mainly based on aluminum silicate-based refractory materials, with some excellent performance, especially high temperature creep performance, living in natural raw materials production Of the high aluminum products first.
