General Description of Tunnel Kiln Refractory Clay Bricks Material Alkali Resistant Insulating Fire Brick:
Clay refractory bricks are refractory products with alumina content of 30~48% made of clay clinker as aggregate and refractory clay as binder.
The raw materials for making clay refractory bricks are clay minerals, and refractory clays can generally be divided into hard clay and light clay. In the refractory manufacturing process, most of the former are used as clinker after calcination; the latter, after adding water, has good plasticity and is easy to sinter, and is mostly used as a binder.
Clay minerals mainly include kaolinite (Al2O3, 2SiO2, 2H2O), dickite (same composition as kaolinite, but different lattice constants), montmorillonite (Al2O3, 4SiO2, 6H2O) and mica minerals.
Clay refractory materials are rich in raw materials, easy to process and cheap, so they are more widely used than any other refractory materials. For high temperature furnaces, hot blast furnaces, iron furnaces, ladle and casting systems and soaking furnaces, heating furnaces, non-ferrous metal melting furnaces, kilns for the silicate industry and chemical industry and chimneys and chimneys of all thermal equipment flue etc.
