Simulation Study on Ultrasonic Measurement of Blast Furnace Throat Temperature
Because the traditional temperature measurement of the blast furnace throat has problems such as the sensor is easy to dam-age,inconvenient to replace,and will lead to suspended materials,a non-contact ultrasonic temperature measurement method is proposed to measure the inside of the blast furnace throat.This method can solve the problem that the temperature measurement sensor is easy to damage and the measured environment changes due to suspended materials,thus affecting the measurement results.It has a broad appli-cation prospect in industry.The physical model of ultrasonic temperature measurement is established based on the finite element soft-ware of COMSOL,and the temperature field is restored by using the least square reconstruction algorithm.The COMSOL simulation shows that the method can simulate the ultrasonic transmission and reception to calculate the acoustic wave transit time,and the installa-tion of six ultrasonic transducers in the simulation environment can effectively complete the detection under different temperature fields,which can provide technical reference for the temperature measurement of the blast furnace throat.
