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