Wear resistance is an important indicator of erosion wear of refractory bricks. Generally speaking, the greater the hardness of refractory bricks, the better the internal quality, and the better the wear resistance
The wear resistance of refractory bricks of different materials is different. According to the statistics of wear amount in actual application, the wear resistance of silicon carbide refractory bricks is the strongest, the wear resistance of high alumina bricks and corundum bricks is in the middle, and the wear resistance of alkaline, siliceous and clay refractory bricks is poor
According to the use, the refractory bricks containing graphite have poor wear resistance, because the graphite is a layered structure composed of intermolecular forces, and its Mohs hardness is low
