在钢水浇铸过程中,需要严格控制钢包到中间包的钢渣量.通过对国外多种下渣检测技术的调研分析及国内多个钢厂的现场试验,提出了一种高灵敏性的钢包下渣检测装置,从硬件上改变了传统采集的单一检测方式,同时在软件上简化了下渣特征提取的算法.通过在现场使用,取得了较好的检测效果,有效控制了进入中间包内的钢渣量,提高了钢厂的经济效益. In the process of molten steel casting, we need to strictly control the amount of steel slag from the ladle to the tundish.Through the investigation and analysis of many foreign slag detection technologies and the field tests of many domestic steel mills, a highly sensitive ladle slag The detection device changed a single detection method of traditional acquisition from the hardware and simplified the algorithm of extracting the lower slag feature in the software.It has obtained good detection effect by using in the field and effectively controlled the steel slag entering the tundish The amount of steel to improve the economic benefits.
