Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical converter equipment, in particular to a convenient installation device for a converter oxygen lance nozzle. Background Art

[0002] Oxygen lance is a key equipment for converter steelmaking. The life of oxygen lance can reflect the stability of converter production operation, steelmaking output, quality and production safety. During the blowing process, the oxygen lance must not only withstand the heat radiation of the high temperature zone with a fire point of about 2500℃, but also withstand the fierce scouring of steel and slag. The working conditions are very harsh. Therefore, the oxygen lance must have a solid metal structure and a strong water cooling system to ensure that it can withstand high temperatures, resist scouring and erosion, and resist vibration. The oxygen lance was first used for blowing oxygen at the top of the open-hearth steelmaking furnace. In 1952, the oxygen top-blown converter steelmaking method came out, and the oxygen lance became its key equipment. Since then, the application scope of oxygen lances has been expanded to electric arc furnaces and ladle refining furnaces; the function has also developed from a single oxygen injection to a composite oxygen lance that can also inject slag powder and combustion powder, as well as a split-flow or double-flow multi-layer oxygen lance with secondary combustion function.
