【Abstract】 Based on the national standard GB/T10297-98 for determining the thermal conductivity of non-metallic material by hot-wire method,the thermal conductivity of SiC-bearing refractory mixture was determined by coating the hot-wire and thermal couple with insulate coating.The reliability and accuracy of the determining results could be raised by using the gauge with high precision accuracy and processing the test data by linear regression method.更多还原
