Here are some explanations of a few common terms for you to better understand: 1. Refractory
Inorganic non-metallic materials with refractoriness over 1580
℃.
2.
Refractory fiber Generic terms of fibrous insulation material with refractoriness over 1580
℃ 3. Melting point
The temperature when the pure substance of solid and liquid is in equilibrium.
4. Refractoriness
It refers to the temperature in which the material can be melt and represents an ability to resist high temperature without being melt.
5. Classification temperature
Also known as the limit temperature, it refers to the limit temperature in which refractory fiber can be used in a short time.
Judging basis: 24 hours heat preservation under the classification temperature and calefaction line is less than 4%.
6. Working temperature
Also known as the long-term use of temperature, it refers to the limit temperature that refractory fiber can be used safely for a long time under this temperature.
Judging basis: 24 hours heat preservation under the working temperature and calefaction line is less than 3%.
