Main features of refractory brick
Nov 19, 2018

1.chemical composition: The main components determine the quality and characteristics of the refractory

2.Volume Density: unit volume weight, high density, indicating good compactness, strength may be high, but the thermal conductivity may be large

3.porosity: did not do specific requirements, but as a manufacturer must strictly control the stomata.

4.Load softening temperature: Also known as high temperature load start deformation temperature, this parameter is very important, marking the material resistance to high temperature resistance

5.thermal shock resistance: the ability to resist rapid changes in temperature without being destroyed

6.compressive strength: the maximum pressure capacity to withstand (normal temperature)

7.Flexural strength: the ability to withstand shear pressure 8, linear rate of change: Also known as heavy burning line changes or called residual line changes, refers to each time in the same temperature changes in the volume of expansion shrinkage changes, if each expansion shrinkage, we define such a linear rate of change of 0
