Fire Clay Bricks

Fire clay bricks are also called chamotte bricks, which are manufactured from unfired refractory bond clay and fire clays (chamotte), fired refractory clay, or similar grog materials. Fire clay bricks have two main components namely 18% to 45% of alumina (Al2O3) and  50% to 70% of silica (SiO2) and about 7% of others.

Introduction of Fire Clay Bricks

Fire clay refractory bricks are also called Chamotte bricks, which are manufactured from unfired refractory bond clay and fire clays (chamotte), fired refractory clay, or similar grog materials. Fire clay refractory bricks have two main components namely 18% to 45% of alumina (Al2O3) and  50% to 70% of silica (SiO2) and about 7% of others.

High density, low-porosity fire clay brick is our featured product in this category. Due to its low apparent porosity rate, it has great features of strong resistance to erosion, high refractoriness under load, great cold crushing strength, high mechanical strength, etc.

Grades of Fire Clay Bricks

High Grade: 1482~1660℃

Medium Grade: 1315~1482℃

Low Grade: up to 950℃

Application of Fire Clay Bricks

Fire clay bricks are used to build heating furnaces and heat treatment furnaces, lining pipes Lining flues, dust collectors of iron-making furnaces, safety lining of rotary kilns, lime kilns, ceramic kilns, glass kilns, and boilers construction.
