Description

Technical Field

[0001] The utility model belongs to the field of metallurgy and relates to an oxygen lance posture adjustment structure. Background Art

[0002] Oxygen lance is an important equipment for steelmaking. In top-blown oxygen steelmaking systems such as converter steelmaking, the oxygen lance is installed in a lifting vehicle and can be raised and lowered vertically with the lifting vehicle. When working, the oxygen lance descends through the oxygen lance mouth of the flue and enters the converter for oxygen blowing smelting production.

[0003] The oxygen lance is installed on a lifting vehicle and needs to be centered so that the oxygen lance can smoothly enter the flue oxygen lance port. The quality of the oxygen lance posture adjustment structure determines the safety, convenience and speed of the adjustment. The oxygen lance posture adjustment is safe, convenient and fast, which not only reduces the labor intensity and operation time of workers, but also facilitates the converter steelmaking production to proceed according to the predetermined rhythm, which is an important guarantee for the normal production of converter steelmaking.

[0004] At present, the push rods used for adjusting the posture of oxygen lances in engineering applications are mostly installed on lifting vehicles. To achieve spatial adjustment of the oxygen lance posture, at least three or more push rods need to be arranged circumferentially on the push rod installation plane to achieve the purpose of arbitrarily adjusting the oxygen lance posture. However, if the arrangement position is unreasonable, the push rod operation will be difficult and unsafe. For example, the push rod arranged on the lifting vehicle and on the medium interface side of the oxygen lance needs to bypass the metal hose installed on the medium interface side of the oxygen lance during operation, which makes the operation difficult and increases the labor intensity of the operator and the risk of safety accidents.
