Refractory material is generally divided into two types, namely, unshaped refractory material and shaped refractory material. Unshaped refractory material, also known as castable, is made from a variety of aggregates or aggregates and one or more binders, which must be mixed with one or more liquids and has strong liquidity. Shaped refractory material generally refers to refractory brick, the shape has the standard rules, can also be built according to the need for temporary processing.

Properties

1. Chemical composition: the main ingredients determine the quality and characteristics of fused cast AZS block.

2. The bulk density: per unit volume weight, large density, explaining density is good, the strength may be high, but the thermal conductivity may be large.

3. The porosity: has no specific requirements, but as a manufacturer must strictly control the porosity.

4. Load softening temperature: also known as high temperature load starting deformation temperature, this parameter is very important, marking the material resistance to high temperature.

5. Thermal shock resistance: ability to resist rapid temperature change and is not damaged.

6. Compressive strength: to withstand (room temperature) the maximum pressure capacity.

7. Bending strength: the ability to withstand shear pressure.

8. The linear rate of change: also called the re-burning line change or called the residual line change, refers to every time the volume expansion shrinkage change under the same temperature change, if each expansion shrink is same, we define such a linear rate change is 0.
