High Alumina insulating brick:
High refractoriness, good heat-resistant ability and the chemical
stability is good under the reducing atmosphere. The application
temperature is ***0~***0℃, and the high pure product's application
temperature may reach ***0~***0℃.
High quality of high alumina insulating brick can be used as the
linings that directly contact the fire however it cannot be used in
the place where eroded by slag directly. Because the high alumina
insulating brick is of good stability under reduction condition it
is widely used as the inner insulation layer in the furnace that
protected by hydrogen or carbon monoxide atmosphere.
1. Main Characters: High refractoriness, low density, high cold
crushing strength and low thermal conductivity, make it save the
industrial furnace’s energy very much.
2. Applications:
High alumina insulation brick is widely used to build the thermal
insulating layers of many kilns and
the linings of industrial kilns, which working temperature is less
than ***0℃.
