What are the characteristics of fire bricks

Fire brick is refractory materials made from refractory clay or other refractory materials.

1, volume density: unit volume, weight, density, indicating good compactness.

2, the apparent porosity: did not do specific requirements, but as manufacturers, we must strictly control the air hole.

3, load softening temperature: also called high temperature load began to deformation temperature, this parameter is very important, marking material resistance to high temperature resistance.

4, thermal shock resistance: resistance to rapid changes in temperature without damage to the capacity.
