Description
Phosphate bonded alumina wear-resistant brick is a kind of refractory brick made primarily from high alumina bauxite clinker, corundum, and mullite, using a phosphate chemical bonding process. These bricks feature high compressive strength, low porosity, excellent thermal shock resistance, good wear resistance, and strong anti-spalling performance.
Advantages: high strength, wear resistance, corrosion resistance, high R.U.L, low creep, anti-stripping, thermal shock stability, and long service life.
