：：Chrome Brick for Petrochemical, Ceramic 
and Building Material Industries：：
　
　　Chrome containing series products developed and produced by LIRR is with good properties in terms of high refractoriness, good corrosion resistance and thermal shock resistance, etc. At present, it is known as the best lining material for coal slurry gasifier in chemical fertilizer and electrical power industrial kilns worldwide. And it is the best choice for critical places in linings of alkalifree glass fiber tank or color TV shell glass tank. Two varieties in this series have the honor to win the name of national grade new products. Excellent application results have been achieved in many domestic major enterprises.

Application

Used in some parts of coal slurry gasifier lining where slag corrosion is slight, or used in lining of glass tank

Mainly used as lining material for coal slurry gasifier and other melting devices where slag corrosion is heavy or used in lining of glass tank

Mainly used in glass fiber tank lining, where the corrosion is heavy, especially used in side wall of forming paving part and corner, etc.

Mainly used in glass fiber tank lining, where the corrosion and thermal shock are heavy; also used in some parts of other glass tank where corrosion is heavy such as liquid flow hole, mounting block, etc.

Used as lining materials for high temperature industry kilns such as gasifier and carbon black reactor furnace for petrochemical industry, etc.
