BAIJIAN - Third party testing organization
A type of inorganic non-metallic material with a fire resistance of not less than 1580 ℃. Fire resistance refers to the Celsius temperature at which a conical sample of refractory material can resist high temperature without softening and melting under no load. But defining refractory materials solely based on their fire resistance is no longer sufficient、 and 1580 ℃ is not absolute. The current definition is that materials with physical and chemical properties that allow them to be used in high-temperature environments are called refractory materials. Refractory materials are widely used in industries such as metallurgy、 chemical engineering、 petroleum、 mechanical manufacturing、 silicates、 and power、 with the largest usage in the metallurgical industry、 accounting for 50% to 60% of the total production
