Introduction
High alumina anchoring bricks are refractory bricks used as anchors for refractory castables. Made of high alumina content minerals, these anchoring bricks have high strength, density, and thermal stability.
They can withstand high temperatures and resist corrosion. Our high alumina anchoring bricks provide strong adhesion between refractory castables and furnace bottoms, helping improve furnace integrity and prolong service life.
