Abstract:

Aiming to solve the problems of short service life of lining bricks and over heating of furnace shell due to poor insulation of lining bricks，we studied the refractory lining of the rotary kiln.Based on damage investigation and compounding tests，we developed a kind of composite percast brick with refractory working surface and monolith insulation，by which service life can be extended by over two years and surface temperature of the furnace shell can be reduced by more than 50℃.
