A test device and method for pressure loss of oxygen lance pipe in converter belongs to the field of converter steelmaking technology. It includes equivalent throat nozzle, pressure guide pipe, fixing device, pressure lead-in pipe and gas pressure gauge.The pressure guide pipe is “L” type, and the vertical part is located at the center of the equivalent throat nozzle 9, the horizontal part end is embedded in the side wall of the cylindrical part of the equivalent throat nozzle and extends to the outer wall, which is connected with the fixing device.The fixing device is fixed on the outside of the equivalent throat nozzle and is connected with the pressure guide pipe and pressure lead-in pipe. One end of the pressure lead-in pipe is connected with the fixing device and is connected with the inner cavity of the pressure guide pipe, the other end is connected with the gas pressure gauge.The advantage is that it overcomes the problem that the pressure loss of oxygen lance pipe cannot be determined in converter production, and tests the stagnation pressure at the oxygen lance nozzle under different oxygen flow conditions with the test method in the cold state, which provides reference for the correct design of oxygen lance nozzle parameters and the accurate formulation of converter oxygen lance operation process.
