Embodiment Construction
[0008] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0009] Such as figure 1 The schematic diagram showing the structure of feeding pressurized gas into the oxygen lance is designed for two sets of oxygen lances. During actual application, corresponding adjustments can be made according to the number of corresponding oxygen lances (one number or more).
[0010] Such as figure 1 As shown, a quick repair method for water leakage of a converter oxygen lance of the present invention is to first close the oxygen lance water inlet valve 6, discharge the accumulated water in the oxygen lance 7, and then weld the leak of the gun body, which is characterized in that: The accumulated water in the oxygen lance 7 is discharged by pressurized gas. The pressurized gas is introduced into the oxygen lance water inlet passage by being connected with the gas source through a branch connected to the pipeline on the outlet side...

The invention discloses a method for repairing converter oxygen lances with water leakage. The method comprises the steps of closing a water inlet valve of an oxygen lance, discharging accumulated water in the oxygen lance and then welding leaks of a lance body. The method is characterized in that the accumulated water in the oxygen lance is discharged through pressurized gas, and the pressurizedgas is led into a water inlet channel of the oxygen lance by connecting a branch which is connected with a pipeline on one side of an outlet of the water inlet valve of the oxygen lance with a gas source. The method of forcibly discharging the accumulated water in the oxygen lance shortens drainage time and the time for repairing the oxygen lance, solves the problem of long time for repairing theoxygen lance, and has a remarkable effect. The method has the advantages of prolonging the life span of the oxygen lance, saving production time, guaranteeing smooth steelmaking, meeting requirement on fast production pace and increasing yield and economic benefit.
Description
technical field [0001] The invention relates to a method for repairing a converter oxygen lance, in particular to a quick repair method for leaking water in a converter oxygen lance. Background technique [0002] Oxygen lance is the key equipment of converter steelmaking, its performance and service life directly affect the quality and efficiency of steelmaking. The converter oxygen lance includes a gun body and a Laval nozzle. The gun body is made of three layers of seamless steel tubes concentrically set. The gap between the center tube and the middle tube is the cooling water inlet channel, and the gap between the middle tube and the outer tube It is the cooling water outlet channel, the lower end of the gun body is connected to the Laval nozzle, and the central tube, middle tube, and outer tube of the gun body are respectively connected to the oxygen hose, cooling water inlet hose, and cooling water outlet hose through flanges . Cooling water circulates in the oxygen l...
