Industrial Furnace Alumina Refractory Bricks G-4 Light Yellow Appearance
The first-grade high-alumina brick (the aluminum content is not less than 75% refractory brick) is formed by pressing and calcining a high-quality raw material such as high-quality bauxite and alumina. The high-aluminum brick has a refractoriness of over 1790 °C. The load softening temperature is above 1510 °C, the thermal shock stability is good, and the slag resistance is good.
Our alumina bricks have excellent mechanical strength, good resistance to thermal spalling, and are highly resistant to chemical attack by vilatile alkaies and some slag. We manufacture and design alumina bricks to meet the requirements of a great variety of service conditions thorough quality control.
High-aluminum bricks are mainly used for masonry blast furnaces, hot blast stoves, electric furnace tops, blast furnaces, reverberatory furnaces, and rotary kiln linings. In addition, high-aluminum bricks are also widely used as open-hearth regenerative lattice bricks, plugs for gating systems, and shingles.
1. High refractoriness.
2. Good spalling resistance and wear resistance.
3. Good thermal shock resistance.
4. High mechanical strength.

Anti-stripping alumina brick was produced with special bauxite chamotte, adding aragonite or ZrO2 and pressing under high pressure based on a certain ratio. It has strong Anti-stirping as well as strong resistance to K, NA, S ,CL, low thermal conductivity, which is the ideal material for the transition zone and decomposing zone for cement kiln.
