英文摘要	Because high temperature thermal conductivity of thermal storage salt casting structure used in engineering application is different from value which is measured in conventional laboratory. The mathematical model was set up based on the temperature rising constantly method, thermal conductivity measurement equipment of thermal storage salt in higher temperature was put up, measurement method was described in detail. Taking analytically pure NaCl for testing example, average temperature conductivity and thermal conductivity is 9.39×10-7m2/s and 1.72 W/(m·K) when temperature being between 530°C to 650°C, respectively. The relationship between temperature and time is consistent with equipment results. The measured thermal conductivity is reasonable. In addition, the temperature conductivity and thermal conductivity at each temperature point on a certain temperature range can be measured and have significance for engineering applications. The equipment structure is simple, easy operation and not strict to samples.
