High alumina insulation brick

Quick Detail

Package & Delivery Lead Time

Detailed Description

High refractoriness, good heat-resistant ability and the chemical stability is good under the reducing atmosphere. The application temperature is 1350~1500℃, and the high pure product's application temperature may reach 1650~1800℃. High quality of high alumina insulation brick can be used as the linings that directly contact the fire however it can not be used in the place where eroded by slag directly. Because the high alumina insulation 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 1350℃.
