What are the characteristics of refractory bricks?
Self-properties of refractory bricks
1, chemical composition: the main component determines the quality and characteristics of the refractory material
2, volume density: unit volume weight, density, indicating good compactness, strength may be high, but the thermal conductivity may be large
3, apparent porosity: no specific requirements, but as a manufacturer must strictly control the apparent porosity.
4, load softening temperature: also known as high temperature load began to deform temperature, this parameter is very important, marking the material's 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, bending strength: the ability to withstand shear pressure
