R＆D of brazing carrier of heat storage materials

Based on the background of traditional energy reserves,the strategic significance of solar energy was briefly described,the type and function of heat storage materials and their structure and forming method were introduced. Being taken the tungsten,molybdenum and TZM alloys as an example,the physical and chemical properties of the matrix of the carrier were introduced,and the brazing filler metals that can be used to braze the heat storage material carrier were drawn out and their feasibility was systematically evaluated. The solution to the current technical bottleneck was proposed by regulating elements to get the ideal melting point of filler metals and the microstructures of joints. After that,the brazing equipment-vacuum brazing furnace needed for the heat storage material carrier was introduced,and the type of brazing furnace was discussed in detail. The results show that the induction brazing has the characteristics of fast heating speed and high energy utilization rate. Aiming at the shortcomings that the induction brazing temperature can not be precisely controlled,fuzzy control can be introduced to achieve temperature control,and which has a good development prospects.
