The difference between refractory bricks and insulation bricks

As their names imply, refractory brick is used to withstand high temperature and flame, while insulation brick is used to insulate and reduce heat loss. The insulation bricks seldom directly contact flame, while refractory bricks can directly contact flame. Both have their advantages and are used in different parts of furnaces.

Insulation bricks always have thermal...

Rebonded fused cast AZS block

Rebonded fused cast AZS block is made of AZS frit or waste fused cast AZS block by adding a small amount of kaolin or alumina as binder. Rebonded fused cast AZS block is composed of A12O3 (50-60%), ZrO2 (20-30%) and SiO2 (14-20%).

When heated to a certain temperature, glass phase exuded by fused cast AZS forms mullite with binding agents. Bricks should be fired at...
