The mechanical properties of refractories include compressive strength, flexural strength, wear resistance and high temperature creep.
Compressive strength refers to the ultimate load that the refractory can bear per unit area without being damaged at a certain temperature. The compressive strength of refractories is divided into normal temperature compressive strength and high temperature compressive strength.
Flexural strength refers to the maximum bending stress that a strip specimen of refractory with a certain size can bear on a three-point bending device, also known as flexural strength. The flexural strength of refractory is divided into normal temperature flexural strength and high temperature flexural strength.
Wear resistance refers to the ability of refractory materials to resist the friction, wear and erosion of hard objects or air flow. The wear resistance of refractory depends on its mineral composition, microstructure, firmness of particle bonding, density and strength of the material itself
High temperature creep refers to the plastic deformation that occurs when the refractory bears a certain load less than its ultimate strength at high temperature. The deformation will gradually increase with the extension of time, and even destroy the refractory. This phenomenon is called creep. Creep at high temperature is an important index of refractory beams at high temperature
