Embodiment Construction
[0016] The invention mainly aims at the problem of oxygen lance sticking to steel and / or slag splashing during the converter blowing process, and provides a method for optimizing the converter oxygen lance and a method for optimizing converter smelting.
[0017] According to metallurgical principles, increase the degree of dispersion of the oxygen supply of the oxygen lance and / or increase the angle of the oxygen lance (the angle between the center line of the oxygen lance and the axis of the nozzle hole on the oxygen lance nozzle ) can optimize the smelting of the converter, so the number of holes in the oxygen lance nozzle and the included angle of the oxygen lance can be increased The degree of dispersion of oxygen supply can be improved. However, in smelting practice, it is necessary to consider the penetration depth of the oxygen jet of the oxygen lance on the molten pool and the influence on the stirring of the molten pool, as well as the difficulty of manufacturing th...

The invention discloses a design method for optimizing a converter oxygen lance and a method for optimizing converter smelting. The design method comprises the steps of selecting the number of nozzle holes of an oxygen lance nozzle according to the tonnage of the converter, and calculating the included angle of the oxygen lancer according to a formula shown in the specification, wherein theta represents one half of an included angle between the axes of two adjacent nozzle holes of the oxygen lancer nozzle, phi represents the included angle of the oxygen lance, namely an included angle between the axis of any nozzle hole of the oxygen lancer nozzle and the center line of the oxygen lance, and N represents the number of the nozzle holes of the oxygen lance nozzle. According to the design method for optimizing the converter oxygen lance and the method for optimizing converter smelting, the steel attached to the oxygen lancer in the converter smelting process can be reduced.
Description
technical field [0001] The disclosure relates to a design method for optimizing a converter oxygen lance and a method for optimizing converter smelting. Background technique [0002] The converter is the most widely used equipment for steelmaking in the metallurgical industry. The oxygen lance technology is the core of the converter steelmaking technology. The design level and usage method of the oxygen lance nozzle are directly related to the efficient and stable progress of the converter steelmaking. , and will have a direct impact on the operating rate, the yield of molten iron, the quality of the converter steel and the service life of the oxygen lance nozzle. [0003] In the process of converter smelting in the prior art, due to the unreasonable design and use of the oxygen lance, molten iron and slag are bonded to the body of the oxygen lance and the nozzle during the blowing process of the converter, or the slag and molten iron are sprayed out of the furnace mouth of ...
