摘　　要：在高炉冶炼生产过程中,相较于机械探尺等传统的炉内测量技术,目前国内外出现了基于激光和雷达的料面成像技术。首先,阐述了激光与微波/毫米波雷达为代表的高炉生产环境成像技术及应用,尤其是内部环境恶劣料面成像的国内外现状;概述了激光与微波/毫米波成像的特点,激光测量精度高、准直性好,但抗恶劣环境和干扰能力差;微波/毫米波电磁散射原理的成像技术抗干扰能力强、稳定性好,但存在精度偏低的问题。其次,介绍了国际主流雷达设备类型、料面监测方法及其特点,同时提出了一种新的合成孔径雷达(synthetic aperture radar,SAR)前视凝视高分辨率成像(forward-looking staring high-resolution imaging,FSHI)方法,具有点云高精度主动抗干扰成像特点,并成功应用于国内大型高炉。最后,展望了雷达点云图像处理、料层分布可视化与高炉雷达保护技术,是未来高炉大规模部署成像雷达成功的关键。Compared with the traditional online measurement techniques such as mechanical probes in the iron making process of blast furnace(BF),laser and radar-based burden surface imaging technologies have emerged recently.The key technologies of BF production environment imaging and its application represented by laser and microwave/millimeter wave radar research and development worldwide are described,especially when the internal environment condition is harsh.First,the characteristics of laser and microwave/millimeter wave imaging technology are summarized.The accuracy of laser is higher and the collimation is better,but the ability to resist harsh environment and interference is poor.The radar technology based on the principle of microwave/millimeter wave electromagnetic scattering has stronger anti-interference ability and stability with low resolution.After that,the different types of main radar equipment and burden surface detection algorithms currently applied to BF radar in different ironworks are introduced and analyzed their characteristics.At the same time,a new forward-looking staring high-resolution imaging(FSHI)method is proposed for synthetic aperture radar(SAR),which has the characteristics of high-precision anti-interference imaging of point cloud and has been successfully applied to BF in China.Finally,the radar point cloud image processing,charging distribution visualization and radar protection technology are prospected,which are the keys to the success of large-scale deployment of imaging radar in BF in the future.
