本成果研制的测定装置由高频感应加热设备、熔点炉、光学高温计、真空机组等组成。可以用于测量3000℃以下高温材料的熔点。感应加热设备的功率为15kW,工作频率为300kHz～500kHz;熔点炉内装有涡流集中器,它改变感应圈内磁力线的分布,使发热体和感应线圈很好的耦合,所测样品便可快速升温,炉内的真空度不低于5.332×10-3Pa。发热体架于涡流集中器内孔中间,与涡流集中器感应而发热,加热内部坩
The results of the development of the measurement device consists of high frequency induction heating equipment, melting point furnace, optical pyrometer, vacuum unit and other components. Can be used to measure the melting point of high temperature materials below 3000 ℃. Induction heating equipment for the power of 15kW, the operating frequency of 300kHz ~ 500kHz; melting point furnace equipped with eddy current concentrator, which changes the induction coil magnetic field distribution, the heating element and the induction coil coupling, the measured samples can be rapidly warming , The degree of vacuum inside the furnace is not less than 5.332 × 10-3Pa. The heating element is arranged in the middle of the vortex concentrator inner hole, induces and generates heat with the vortex concentrator, and heats the internal crucible
