Fireclay Bricks High Alumina Refractory Brick

High alumina refractory brick is dense shaped refractory material. With high refractoriness and mechanical behavior under high temperature, refractory brick is the necessary material of high-temperature services, mainly used for industrial furnaces and kilns and thermal equipment.

High alumina refractory brick has wide applications, mainly used in metallurgy, construction(cement and glass), petroleum, chemical industry, electric power and machine building.

Linquan series alumina bricks are high quality dry pressed alumina bricks, ranging from 35% to 95% in alumina content. $Fireclay Bricks High Alumina Refractory Brick$

High alumina refractory brick is made from bauxite of super quality, bonding chamotte and additives. The advantages of these products are high refractoriness, anti alkaline/acid erosions, good strength under high temperature and good thermal shock resistance.They were widely accepted in thermal equipment of metallurgy, petroleum, chemical industry, construction materials and machinery, etc.
