Embodiment Construction
[0018] A method for reducing molten steel nitrogen in the steelmaking link provided by the invention comprises the following steps:
[0019] Step S1: Controlling the reblowing parameters of the converter and adjusting them in stages;
[0020] Sampling and testing by comparison test, analyzing the data (TSO assay nitrogen), summing up that it is beneficial to control nitrogen to appropriately reduce the reblowing flow rate in the middle and later stages of blowing and tapping process For control, from the initial when the oxygen supply is 0%-50%, the re-blowing argon flow is controlled at 300m 3 / h, when the oxygen supply is 50%-80%, the reblowing argon flow rate is controlled at 480m 3 / h, when the oxygen supply is 80%-100%, the reblowing argon flow rate is controlled at 600m 3 / h, the re-blowing argon flow rate in the tapping process is controlled at 300m 3 / h. Adjusted so that when the oxygen supply is 0%-50%, the reblowing argon flow is controlled at 300m 3 / h, when th...
