Problems solved by technology
[0009] The disadvantage of the above replacement method is that the workload is large and time-consuming. The workload is mainly reflected in the dismantling and installation of the cross arm 3, and the overall adjustment of the cross arm 3 after installation. The entire replacement process generally requires 20 people. Cooperating with each other takes 20 hours to complete
Long replacement and maintenance time will undoubtedly have an impact on the production schedule. Therefore, how to provide an efficient method for replacing the column to reduce the time spent in the replacement process has become a technical problem to be solved urgently by those skilled in the art

Embodiment Construction
[0028] For ease of understanding, the present invention will be further described below in conjunction with the accompanying drawings.
[0029] see figure 1 , is a schematic diagram of the layout of the refining furnace electrode system. A method for replacing the refining furnace electrode column provided by the embodiment of the present invention includes the following steps:
[0030] S1, remove the dust cover 5 above the cross arm 3, so that the covered area of the dust cover 5 is in an open state when it is working.
[0031] In the working state, the dust removal cover 5 covers the top of the cross arm 3, and the space for hoisting under the dust removal cover 5 is very limited. Therefore, first removing the dust removal cover 5 can make the hoisting space larger, and there is no dust removal Covering of cover 5, cross arm 3 can be hoisted upwards together with column 7 and lift cylinder 9 together.
[0032] S2, remove the connection between the cross arm 3 and the wat...

The invention provides a method for replacing an electrode stand column of a refining furnace. The method is characterized in that firstly, a dust hood (5) above a cross arm (3) is removed, and the operation space is increased; then, the cross arm (3), the stand column (7) and a lifting cylinder (9) are jointly hoisted as a whole, and after the cross arm (3), the stand column (7) and the lifting cylinder (9) are hoisted to a spare part repairing area, a new stand column (7) replaces the old stand column (7); and finally, the cross arm (3), the new stand column (7) and the lifting cylinder (9) are installed to the original positions as a whole, and the dust hood (5) is moved back. Compared with a traditional stand column replacing method, the defect that the operation space surrounding the cross arm is narrow is overcome, the time in disassembling, assembling and adjusting the cross arm is less, and thus the stand column replacing efficiency is effectively improved.
Description
technical field [0001] The invention relates to the technical field of ladle refining furnaces, in particular to a method for replacing an electrode column of a refining furnace. Background technique [0002] The electrode system of the refining furnace includes transformers, short nets, water-cooled cables, cross arms, electrode columns and other equipment. The electrode columns are used to lift the electrodes up and down, and are divided into two types in structure: fixed column type and movable column type. In the movable column structure, the cross arm and the electrode column are connected to form an inverted L-shaped structure, and the electrode column can be raised and lowered between several pairs of guide wheels, and the lifting of the electrode column usually adopts a hydraulic transmission method. [0003] Such as figure 1 As shown, the steel ladle 1 is located under the dust removal cover 5, the dust removal cover 5 spans the dust removal rails 4 on both sides, ...
