fireclay bricks

High Alumina Bricks for general uses are 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, machinery and militaries etc.
