Characteristics of Zirconia 20 Brick
Zirconia 20 brick have these characteristics:
- Dense structure
- Good erosion resistance
- Good thermal shock resistance
- High high temperature strength
Application of Zirconia 20 Brick
- Glass industry: Zirconia 20 brick is commonly used in the pool wall, flow hole, charging port, bubbling area and other parts of the glass melting furnace that are directly in contact with high-temperature and highly corrosive glass liquid.
- Metallurgical industry: Zirconia 20 brick can be used for slag lines in the ladle refining area, RH/OBS vacuum refining furnace immersion tubes, heating furnace slide rails and other parts that are subject to erosion and thermal circulation of molten steel and slag.
- Chemical industry: Zirconia 20 refractory brick is also used in the core lining of ethylene cracking furnaces, coal gasification furnaces, carbon black reactors and other high-temperature and complex chemical corrosion environments.
