Refractory castable

There are many expressions and testing methods of the thermal shock resistance of refractory castable materials.Briefly introduce the following:
1 .Refractory castable materials rose to a different temperature after quenching (air cooling or water cooling), the maximum temperature difference between the surface of the specimen was measured.
2 .refractory castable material to the predetermined temperature, quenching (air cooling or water cooling), after the completion of the specified number of times, the residual flexural strength of specimens and the ratio of bending strength before the normal temperature thermal shock, the measured strength retention rate.
3. the refractory castable material rises to a predetermined temperature, quenched (air cooling or water cooling), and repeated testing until the number of macroscopic cracks produced in the material.Refractory mortar
The new crack in the heat epicenter, and dehiscence,the exfoliation, the break, and so on, which are caused by the new crack and the original crack growth, are called thermal shock damage.Thermal shock damage is the result of thermal stress, and the deformation of the refractory castable material is restrained by the thermal stress.When the refractory castable material changes in temperature, the deformation is restrained by the stress generated by the thermal stress.When the linear expansion coefficient is different, the temperature changes, the uniform thermal expansion of the object is affected by the temperature gradient, and the phase transition, it will produce thermal stress.The thermal stress is proportional to the elastic modulus and elasticity of the material, and the elastic strain is equal to the product of the linear expansion coefficient and the temperature variation.Refractory mortar
