摘　　要：介绍了一种冶金高炉料罐物位计接管口的灰污自动反吹装置。在该技术方案中,通过安装自动反吹装置,可及时清除物位计接管口处的沉积灰污,进而实现了不需高炉休风停机,便可解决在线恢复料罐物位检测的技术难题。This paper introduces an automatic back blowing device for ash contamination at the nozzle of the level meter of blast furnace charge tank. In this technical solution, through the installation of automatic back-blowing device, the utility model can timely remove the deposited ash pollution at the nozzle of the level gauge. Thus, the system can automatically continue to detect the level of the material tank without stopping the blast furnace.
