Fireclay chamotte lining high alumina resistant fireproof heat refractory fire clay brick
Product Description
Laurel Alumina Bubble Brick is a new type of high-temperature heat insulation material. It adopts alumina bubble ball as the main raw materials, high-performance ultrafine powder as the annexing agent and organic substance as the binding agent through molding and drying, and then are fired in the high-temperature shuttle kiln. It is widely used in the high-temperature kilns of the metallurgy, chemical engineering, glass, ceramics and refractory materials industries.
