1.wear Resistance: we all know I don't say much, it is one of the best indicators of refractory quality

2.Thermal conductivity: Under the condition of unit temperature gradient, the heat flux rate on the unit area of the material is related to porosity.

3.Impact Resistance: Do not have to explain it, good impact resistance, long service life .

4.slag resistance: In high temperature small resistance to slag erosion without damage to the ability.
