Description

Technical Field

[0001] The utility model belongs to the technical field of steelmaking equipment and relates to an oxygen lance convex ball seat supporting 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 it can enter the flue oxygen lance port smoothly. Oxygen lances with different support structures have different centering operation steps and different working times. Oxygen lance centering is 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 oxygen lance support structure used in engineering applications is mainly a cross-plane support structure.

[0005] The cross-plane supported oxygen lance can be translated on the installation plane, and the oxygen lance posture can be adjusted by adding gaskets under the support feet. In theory, the oxygen lance can be adjusted to the ideal state where the lance body is vertical and coincides with the center of the oxygen lance mouth. However, in actual use, it is found that the thickness of the gaskets required to be added under the support feet of different oxygen lances is not the same, and the thickness of the gaskets needs to be increased or decreased multiple times to make the oxygen lance reach a vertical state. At the same time, each time the lance is raised and the gasket thickness is adjusted, the center of the oxygen lance will change, and the center position of the oxygen lance needs to be readjusted. All these make the centering operation of the cross-plane supported oxygen lance time-consuming and labor-intensive, and it is difficult to achieve the ideal centering effect. Utility Model Content

[0006] In view of this, the purpose of the utility model is to overcome the problem of difficult operation of centering the oxygen lance with a cross-plane support, and to provide an oxygen lance convex ball seat support structure to achieve convenient and rapid operation of centering the oxygen lance, and the oxygen lance support structure can adapt to different types of lifting vehicles.
