Abstract To achieve the detection of the hot metal and slag flow，three parameters must be detected which includes the metal flow velocity， the tap hole diameter and the mass increase rate of the hot metal ladle. According to physicochemical property of the high temperature liquid metal and slag， it is difficult to achieve accurate direct measurement. A non-contact measuring method for hot metal and slag flow is proposed after research and field trip. Based on the Doppler effect， the metal and slag drainage rate of Shougang Jingtang 5 500 m3 blast furnace was measured on-line，and at the same time video camera monitors the section of tapping hole， and the change of tap hole diameter was recorded and observed in real time. Combining the mass increase rate of hot metal in the weighing system of iron ladle， analyzing and calculating the metal and slag drainage rate and slag ratio of blast furnace， verifying the reliability of detection system in contrast with the actual theoretical value.
