Refractory brick wear resistance and temperature. Some materials such as high-alumina refractory bricks, generally believed that it is in a certain temperature (such as 700 ~ 900 ℃ in the lower than the elastic range), the higher the higher the wear resistance, you can think that when the temperature increases with the elastic Modulus increases, wear resistance is reduced. When the temperature increases, to reach the maximum modulus of elasticity, with the elastic point of the reduction, wear resistance has improved. Such as high aluminum refractory brick at 1200 ~ 1350 ℃, the wear resistance is even better than the room temperature. When the temperature is further increased, up to 1400 ℃ or more, due to the sharp decline in liquid viscosity in the refractory bricks, wear parts will be reduced. Some refractory bricks such as chromium-containing products, with the temperature rise, wear resistance increased.
