Product Details

Linquan Refractory 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.
