Anti Corrosion Hot Blast Stove 55 Al2O3 Clay Refractory Brick
Definition:
Annec's clay refractory bricks is made from clinker clay by mixing, forming, drying, sintering and matching characterized by good resistance to corrosion and abrasion, good thermal shock resistance, good spelling resistance, high mechanical strength, good volume stability under high temperature.The working temperature is less than 1350℃. The content of the Al2O3 is more than 42%,SiO2 is more than 50%. and the quality is on the prime level of the market.
Advantage:
1. High refractoriness,
2. High-temperature endurable.
3. Good corrosion resistance.
4. Good spalling resistance and wear resistance.
5. Good thermal shock resistance.
6. High mechanical strength.
7. High-temperature creep rate is low.
8. Good volume stability at high temperature.
Application:
1. Iron & steel making:Blast furnace,hot blast stove,hot metal ladle,tundish,soaking pit,heat treatment furnace,refining furnace,reheating furnace,metal mixter furnace,cupola furnace.
2. Non-ferrous Metal:Smelting furnace,reverberatory furnace.
