Applications of High Alumina Ceramic Tube

1. In blast furnace ironmaking, high alumina ceramic tubes are used to transport furnace gas and slag above 1500 ℃ to avoid oxidation loss of metal pipelines; In non-ferrous metal refining furnaces, their anti-corrosion properties effectively resist the erosion of molten metal and ensure continuous production.

2. High alumina ceramic tubes, as lining materials for boiling furnaces in sulfuric acid production, can withstand strong corrosive gases such as SO ₂ and SO 3 .

3. The coal powder conveying pipeline of coal-fired power plants adopts high alumina ceramic tubes lining to reduce the erosion loss of high-speed particles.

4. As a heating element support tube for vacuum annealing furnaces, High alumina ceramic tubes maintains insulation and structural stability above 1300 ℃; In continuous heating furnaces, replacing metal guide rails can reduce workpiece deformation caused by high-temperature creep.
