Problems solved by technology
[0002] In the production process of vanadium extraction in the converter, the effect of the oxygen lance directly affects the smelting effect of the converter, the blowing time and the oxidation rate of vanadium. The weight of the oxygen lance is usually relatively large, and the existing lifting method usually relies on the work Personnel manipulate the ordinary manual electric hoist to lift. The disadvantages of this method are: the lifting and lowering speed is slow, the work efficiency is low, and the oxygen supply effect of the oxygen lance is also affected; when the oxygen lance enters the oxygen lance hole on the furnace cover When it is necessary to straighten the staff, it is time-consuming and labor-intensive and poses certain hidden dangers to the personal safety of the staff.

Description
technical field [0001] The invention relates to the technical field of vanadium extraction in a converter, in particular to a rapid lifting device for an oxygen lance of a vanadium extraction converter. Background technique [0002] In the production process of vanadium extraction by converter, the use effect of oxygen lance directly affects the smelting effect of converter, blowing time and vanadium oxidation rate. The weight of oxygen lance is usually relatively large, and the existing lifting method usually relies on work Personnel operate the ordinary manual electric hoist to lift. The disadvantages of this method are: the lifting and lowering speed is slow, the work efficiency is low, and the oxygen supply effect of the oxygen lance is also affected; the oxygen lance enters the oxygen lance hole on the furnace cover. When it happens, it requires staff to straighten, which is time-consuming and labor-intensive and poses a certain hidden danger to the personal safety of t...
