From the appearance point of view, firebricks give people a very strong and durable feeling. In fact, the compressive strength of refractory bricks is really high, but what are the physical and chemical properties of refractory bricks?

1.impact resistance: that is, good impact resistance, long service life.

2.thermal conductivity: under the condition of unit temperature gradient, the heat flow rate through the unit area of the material is related to the porosity.

3.resistance: the ability to resist the erosion of slag at high temperature without being destroyed.

4.wear resistance: this refractories quality is one of the best indicators.
