Refractory brick is made of stone powder and slime, firebrick is fired in a 1300 degree Celsius kiln. The upper limit is 1500 degrees Celsius above normal pressure. However, refractory bricks have refractory materials of a certain shape and size, according to the preparation process, fireproof brick is divided into non-burned bricks, fired bricks, fused bricks, refractory fire bricks. Divided into standard fire bricks, ordinary bricks, special bricks, etc. according to shape and size of fire bricks.
Refractory fire bricks can be used as high temperature building refractory materials and structural materials for building furnaces and various thermal equipment, and can withstand various physical and chemical changes and mechanical effects at high temperatures. Such as, refractory clay brick, high alumina brick, silica brick, magnesia brick.
Refractory soil, usually refers to the folk point furnace, a kind of soil used for the furnace, the upper limit---clay refractory soil around 1500 degrees Celsius under normal pressure. Characteristics and uses of fireproof refractory soil: clay refractory bricks are weakly acidic refractories with good thermal stability, suitable for hot blast stoves, various boiler linings and flue, smoke chambers. Refractory fire bricks specification form: standard shape of fire brick, general shape of fire bricks, special shape and special shape brick of refractory brick.
