Description
Fire clay brick is made of local top grade fireclay materials under the high temperature according to the lasted national standard, which possesses even bulk density, high strength, low thermal conductivity and low impurity. Fire clay refractory brick has wide usage and the largest production.
Features
1. Low coefficient of linear expansion.
2. Low thermal conductivity.
3. Strong resistance to the acid slag erosion.
4. Excellent thermal shock resistance.
5. High Refractoriness under load.
6. Low high-temperature creep rate.
