高炉炉墙厚度在线监测的研究该项目是国家科委下达的科技攻关项目。它利用超声测厚原理，智能转换器发射一个超声波脉冲。该声波沿测杆轴向传播到测杆前端面后反射，反射波传播到压电晶体，由压电晶体产生一个电信号，计算机检测出从发射波到反射波之间的时间差，由计算得... The blast furnace wall thickness online monitoring of the project is the State Science and Technology Commission issued scientific and technological projects. It uses the principle of ultrasonic thickness measurement, intelligent converter transmits an ultrasonic pulse. The sound wave along the spindle axial rod spread to the front of the rod reflection, reflected wave propagation to the piezoelectric crystal, the piezoelectric crystal to generate an electrical signal, the computer detected from the transmitted wave to reflected wave between the time difference calculated ...
