Refractory Bricks Lqh Lqhab Lqfc - China

Refractory bricks LQH LQHAB & LQFC 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.
