Heating Furnace 1530C 2.4g/Cm3 Refractory Fire Bricks High Refractoriness
Refractory Fire Bricks Description
The Refractory Fire Bricks is an alumina-silicate refractory material in which the Al2O3 content is more than 55%, and is calcined from a high-content alumina raw material such as a silicone raw material or a bauxite. High heat resistance and high temperature resistance at 1770°C and above. Has good slag resistance, mainly used in the masonry of steelmaking electric furnace, glass furnace, cement rotary furnace and so on.
1. Refractoriness
More refractory than refractory clay bricks and semi-silica bricks, up to 1750-1790C, belonging to high-grade refractory materials.
Refractory Fire Bricks Features:
1. High temperature of use
2. Optimize the structure and reduce the weight of the furnace
3. Saving materials
4. Save energy
