10. Applications : Another alternative
for fireclay, high alumina bricks for the same application such as back-up/sidewall-lining
of kiln and furnaces, kiln-car floors, are furnace roof , glass furnace
reheating and blast furnace. Some application for cyclone preheaters
in cement rotary kiln, burner pipe and block are also used. |
