Product Description Alumina bubble brick is made from alumina bubbles and alumina powders, together with other adhesives, burnt by 1750oC. It belongs to the super high temperature thermal insulation material which is widely used as the industrial furnace lining under 1800 oC . Since its high porosity, it cannot be applied to the part that contact slag, or it will be damaged by the slag permeation. Also if used as the furnace lining, the temperature rising rate cannot be too sharp, or it will crack and reduce its service life.APPLICATIONMetallurgy induction furnace liningPetrochemical industrial gas furnaceThermal insulation liningReaction Furnace liningFEATURES Thermal stabilityLow thermal conductivityHigh porosityHigh refractoriness under loadLow thermal linear change Company ProfileGreenergy Refractory &Insulation Material Co., LtdYour reliable partner for refractory materials.As one of the leading company of refractory products in China, Greenergy Refractory& Insulation Material Co., Ltd enjoys close proximity to her customers, during long time in the market, we accumulate a lot of experiences in refractory materials for Steel plant, Boiler, Cement, Ceramics, Aluminum, Petrochemical and Metallurgy industries as well as other thermal treatment industries.
