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

8. Linear change rate: also called re-burning line change or residual line change, which refers to the change of volume expansion and contraction each time in the same temperature change. If each expansion and contraction is the same, we define such linear change rate as 0

Physical and Chemical Properties of Refractory Brick

1. Wear resistance:

2, thermal conductivity: unit temperature gradient conditions, through the material unit area on the heat flow rate, with the pore rate.

3. Impact resistance: No need to explain, good impact resistance and long service life

4. Slag resistance: the ability to resist slag erosion at high temperatures without being destroyed
