What are the characteristics of refractory brick?
2. The bulk density: weight per unit volume, density, indicating good density, strength may be high, but the thermal conductivity may be large.
3. Apparent porosity : did not do specific requirements, but as a manufacturer must strictly control apparent porosity.
4. Load softening temperature: also known as high temperature load began to deformation temperature, this parameter is very important, marking the material resistance to high temperature resistance
5. Thermal shock resistance: the rapid changes in temperature without the ability to damage
6. Compressive strength: to withstand (room temperature) the maximum pressure capacity
7. Bending strength: the ability to withstand shear pressure
8. The linear rate of change: also called the re-burning line changes or called the residual line changes, that each time in the same temperature changes in the volume of expansion and contraction changes, if each expansion contraction, we define such a linear rate of change of 0.
