摘要
在电磁场作用下 ,由于液态金属流动的多维性和不稳定性及其电磁场效应 ,传统的速度测量方法与设备遇到了困难。为了给利用数学物理模型研究和分析冶金过程的电磁现象提供可靠的信息 ,根据速度传感理论 ,开展了电磁场作用下液态金属速度测量技术的研究 ,研制了灵活方便的测量装置 。
Because of multi-dimension and turbulence of liquid metal flow and electromagnetic field effect, the velocity measured by the conventional method and instrumentation becomes difficult and in vain. To provide the useful and reliable information for electromagnetic phenomena analyzed by mathematical and physical model in metallurgical processes, the measurement of flow velocity of liquid metal influenced by electromagnetic field is important and necessary. Based on the theory of velocity transducer, some new measuring technologies and corresponding apparatuses of flow velocity are developed and applied in laboratory and in plant under condition of electromagnetic field.
