1, melting point

The temperature at which the internal and solid phases of the material are in equilibrium.

2, refractoriness

The temperature at which the material is given a specific softening degree at high temperature. It represents the ability of materials to resist high temperatures without being melted.

3, classification temperature

Also known as the ultimate use temperature, refers to refractory fiber at this temperature can be used for a short time limit temperature. Judgment basis: refractory fiber at classification temperature 24 hours heat preservation, heating line contraction is less than 4%.

4, working temperature

Also known as the long-term use of temperature, refers to refractory fiber at this temperature can be used safely for a long time limit temperature. Judgment basis: refractory fiber at work temperature for 24 hours, heating line contraction is less than 3%.
