It sets, the dust excluding hood includes left side, right side, trailing flank, leading flank and air outlet, the left side, right side, trailing flank
It is closed side, leading flank is semi-open-type side, and the bottom of the left side, the top of right side are separately installed with A
Wheel group and B wheel group are equipped with rail set, the A wheel group and B wheel group in ladle refining furnace two sides and rail set connect
It connects, and can walk on the rail set, envelope wall is arranged in the vertical plane along rail set, and the leading flank can be with envelope wall
Fitting.
Preferred: the rail set is that one or more snippets rail or I-steel form.
Preferred: the bottom of the left side, the top of right side pass through bolt respectively and are equipped with A wheel group and B wheel
Group.
The utility model has the following technical effect that mobile LF furnace height rail movable dust removal cover compared with prior art, makes
Its leading flank is bonded with envelope wall, can effectively collect emerge from the electrode hole between LF furnace electrode and water cooled cover it is a large amount of
Flue gas and dust avoid environmental pollution caused by flue gas and dust leakage, at the same when meeting smelting rise fall of electrodes height
It is required that solving the problems, such as maintenance cantilever crane to the replacement lifting altitude of electrode.
