It is very complex when working inside the CFB boiler , the materials in circulation system flow high with big volume. So it requires using high strength refractory and wear-resisting materials on the liner of boiler. High strength wear-resisting refractory castable is mainly made up of corundum ,carborundum and the stunts burned bauxite, matched with superfine powder and composite additive. Its characters are high strength during medium temperature in early stage , good performance during high temperature , steady volume, strong penetration of slag resistance and corrodibility, easy construction and strong lining structure which is one of the best wear-resisting materials used in CFB Boiler.
