1. The thermal conductivity is tested according to the flat plate method. 2. The performance index is the measured value without adding steel fiber. 3. 815℃ reburning linear rate of change and 815℃ linear rate of change data should be the same.4. Thermal shock stability (815℃, air-cooled) Class A, Class C: ≥10 times. 5. The thermal conductivity of Class A high wear-resistant lining is not used as an evaluation index for material testing, and is only for reference when calculating wall temperature.
