【Abstract】 The principle, device and technique of hot-wire thermal conductivity testing are discussed. The thermal conductivities of some metallurgical powder are tested by using this method, and the relation between thermal conductivity and temperature are obtained. It’s proved that this method can be used for measuring the thermal conductivity of metallurgical powder, and the repeatability of the results are very well, the fluctuation ratio are ±3%.更多还原
