What is the degree of refractory?

High temperature resistant properties of refractories. Usually refractory degree is more than 1580 DEG C inorganic non-metallic materials become refractory material. Impurities refractoriness depends on the material, chemical and mineral compositions and various strong of flux content. In practical application, and never to refractoriness as a temperature maximum limit, but only as an important reference to the use of the maximum temperature value, the actual use of the temperature of refractory material is much lower than the degree of fire resistance.

Load softening temperature is an important index of deformation temperature on the action of high temperature and load to measure the refractory material, the structure strength it is to some extent represents the refractory materials under the conditions of use, that is to say the ability of refractory material to resist the constant weight load and heat load interaction and maintain stable, is a relatively close to the actual work performance index of refractory material.
