Abstract

The invention discloses an ultrasonic-based material melting point measuring device. The device comprises a microprocessor, an ultrasonic transceiver module, a probe module, a temperature measuring wave guide rod, an acquisition module and an alarm module. The ultrasonic transceiver module is used to emit an ultrasonic signal and receive an ultrasonic echo signal and a temperature value. The probe module is connected to the ultrasonic transceiver module and is used for transmitting an ultrasonic signal to the temperature measuring wave guide rod and a sample piece, and is used for transmitting the ultrasonic echo signal of the sample piece and a temperature measured by the temperature measuring wave guide rod to the ultrasonic transceiver module. The temperature measuring wave guide rod is used for measuring the temperature of a high temperature furnace. The acquisition module is connected to the ultrasonic transceiver module and is used for storing the ultrasonic echo signal and the temperature value. The microprocessor calculates a melting point of the sample piece according to the ultrasonic echo signal and the temperature value, and when the melting point reaches a threshold, the alarm module is controlled to give an alarm. By using the device of the invention, the melting point of the sample piece can be automatically measured, compositions are simple, cost is low, operation is convenient, and a melting point measuring range is large.

Description

technical field [0001] The invention relates to the field of material melting point measurement, in particular to an ultrasonic-based material melting point measurement device. Background technique [0002] Melting point is one of the important parameters of materials. Melting point measurement is the basic means to identify the nature of substances and one of the important methods to determine the purity of substances. Melting point measurement plays an important role in aviation, aerospace, metal, material, chemical and pharmaceutical industries. [0003] The melting point affects the range of use of the material, especially in areas where heating or temperature is involved. For example, in the design of nuclear reactors, in order to increase thermal power and reduce costs, it is necessary to increase the operating temperature of fuel elements as much as possible. However, if the operating temperature of the element is too high, the uranium dioxide fuel pellets will be m...
