Product Information
High alumina arc bricks are refractory bricks used to line furnace doors and arches. Made of bauxite clays with an alumina content of 70% to 90%, these arc bricks exhibit high refractoriness, excellent spall resistance, and superior corrosion resistance.
The densely compacted bricks have a low porosity and withstand high temperatures, pressure, and heavy loads. Our high alumina arc bricks prolong furnace campaign life, reduce energy consumption, and increase productivity. They are essential refractory components for industrial furnaces such as blast furnaces, arc furnaces, petroleum refining furnaces, and gasification furnaces.
