Dovetail Alumina Ceramics Sheet


Product description

Dovetail alumina ceramic sheet are generally used in working conditions with large material particles, high temperatures, fast wind speeds, and serious wear. Our commonly used dovetail porcelain types are 20mm, 25mm, 30mm, etc., and we weld the steel bars to a 6mm thick steel plate according to a certain layout , And then pass the dovetail alumina ceramic sheet into the steel bars one by one. The ceramic and steel plates are filled with high temperature resistant inorganic viscose. The steel plates are designed with edging to effectively protect the ceramics.

The scope of application

Dovetail alumina ceramic sheet is mainly used in power plant coal mill body, separator, pulverized coal pipe and flue, etc., also used in steel plant dust removal equipment and waste heat power generation equipment, and also used in cement plant cyclone separator and The coal mill system, raw meal system and other equipment can withstand temperature up to 750 degrees. Due to the welded guide rail clamping groove structure, the ceramics are clamped to the clamping groove and never fall off. And its life is more than 10 times that of welding ceramics. A large number of supplies for power plant flue and steel mill dust removal equipment.


Product features

Super wear resistance: wear resistance is more than 20 times that of ordinary carbon steel;

Firm installation: dovetail steel bar structure and inorganic glue are double fixed to ensure that the ceramics will not fall off when running at high temperature;

High temperature resistance: the highest temperature resistance is 750 degrees, meeting the needs of high temperature working conditions;

Light weight: the density is less than half that of steel;

Easy to replace: The liner is designed with bolts, and customers can install and replace them by themselves;

Impact resistance: It adopts wear-resistant materials with better toughness, which can be used on high-temperature and high-impact equipment.


Adaptation medium

Solid powdery particles, such as coal powder, limestone powder, clinker, cement, etc., block special materials such as coal, coke, slag, cement clinker, limestone, etc.
