Mainly there are water cooled cover, arc heating system and feeding device.Wherein, bell is sealed for ladle mouth, keeps restoring by force in furnace
Property atmosphere and prevent molten steel from radiating, water cooled cover is equipped with fume disposal dust collection facilities.During liquid steel refining, due to arcing and
Charging, Argon feed silk in smelting process, generate a large amount of flue gases and dust, enter induced duct by water cooled cover side dedusting air hose
Road extraction is taken away by dedusting fan.But existing dust pelletizing system is difficult to sufficiently trap it, and volume of smoke is emerged from electrode hole, is emitted
Flue dust out generates interference to the sight of top driving operative employee, brings security risk to driving lifting operation, causes to environment
Serious pollution, directly endangers the physical and mental health of employee.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of LF furnace height rail movable dust removal covers, specifically
Technical solution are as follows:
A kind of LF furnace height rail movable dust removal cover, including ladle refining furnace, the ladle refining furnace include dedusting pipe network, electrode,
Bell, ladle and feeder pipe, it is characterised in that: further include dust excluding hood, envelope wall, A wheel group, B wheel group and rail set, institute
Stating dust excluding hood includes left side, right side, trailing flank, leading flank and air outlet, and the left side, right side, trailing flank are
Closed side, leading flank are 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 in ladle refining furnace two sides, and the A wheel group and B wheel group are connect with rail set,
And can walk on the rail set, envelope wall is arranged in the vertical plane along rail set, and the leading flank can be pasted with envelope wall
It closes.
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 present invention has the following technical effect that mobile LF furnace height rail movable dust removal cover compared with prior art, before making it
Side is bonded with envelope wall, can effectively collect a large amount of flue gases emerged from the electrode hole between LF furnace electrode and water cooled cover
And dust, the requirement for height of rise fall of electrodes when avoiding environmental pollution caused by flue gas and dust leakage, while meeting smelting,
Maintenance cantilever crane is solved the problems, such as to the replacement lifting altitude of electrode.
