摘　　要：由于传统高炉炉喉测温存在传感器易损坏、更换不便、会导致悬料等问题,提出一种采用非接触式超声波测温工艺对高炉炉喉内部实施测量的方法,该方法可很好地解决测温传感器易损坏同时因悬料造成被测环境改变从而影响测量结果的问题,在工业中有广泛的应用前景,基于有限元COMSOL建立超声波测温物理模型,使用最小二乘重建算法对温度场进行还原,通过COMSOL仿真,表明该方法可模拟超声波发射接收计算声波飞渡时间,安装6个超声波换能器于仿真环境可有效完成在不同温度场下的检测,可为高炉炉喉温度测量提供技术上的参考与借鉴。Because the traditional temperature measurement of the blast furnace throat has problems such as the sensor is easy to damage, 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 application prospect in industry. The physical model of ultrasonic temperature measurement is established based on the finite element software 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 installation 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.
