高炉风口回旋区深度是高炉实现最佳冶炼的重要参数之一。简要介绍了回旋区深度理论建模计算、经验公式计算的研究及不足,同时介绍了炉芯取样、风口探针、激光雷达、微波雷达等几种风口回旋区深度直接测量技术的测量原理及应用现状。通过对各种直接测量技术的分类讨论和优劣对比,得出微波测量是1种较为有效的回旋区深度测量方法。在完善各种回旋区深度直接测量方法的同时,建议结合CCD成像等其它监测系统同步完成风口多项指标的测量。
Blast furnace tuyere area depth is one of the most important parameters for blast furnace to achieve the best smelting. This paper briefly introduces the calculation and calculation of the theoretical formula of the cyclotron region and the empirical calculation of the shortcomings. At the same time, the principle and application of the direct measurement technology of several tuyere raceways, such as core sampling, tuyere probe, laser radar and microwave radar, are introduced status quo. By discussing the advantages and disadvantages of different kinds of direct measurement techniques, it is concluded that microwave measurement is a more effective method for measuring the depth of the raceway. While perfecting the methods of direct measurement of depth in all kinds of convolutions, it is suggested to measure the multiple indexes of tuyere simultaneously with other monitoring systems such as CCD imaging.
