Description
Technical field
The utility model belongs to the refining device of steel, relates in particular to the ladle refining furnace electrode lifting device.
Background technology
Ladle refining is the effective measures of improving the quality of steel and enlarging the kind of steel, by more and more enterprises is adopted.But in the ladle refining process, electrode is accurately located and stable elevation is again an insoluble difficult problem.The electrode lifting mechanism of current use comprises that oil cylinder is connected with column, and column is connected by bolt with conductive cross arm, and conductive cross arm is held terminal clamp and the electrode band-type brake of establishing holding electrode in addition.Its shortcoming is that conductive cross arm only depends on bolt to be connected with column, owing to three-phase current unbalance usually occurs in the heating process, electrode, conductive cross arm suffer intense impact, cause the bolt looseness between column and the conductive cross arm, conductive cross arm produces horizontal-shift, contact with water cooled cover, cause that bell is breakdown, the accident of lead rupture takes place; In order to keep ordinary production, the frequent stopping production of having to adjusted bolt, and operating rate reduces, and production efficiency descends.
Summary of the invention
In order to overcome the shortcomings and deficiencies that prior art exists, the purpose of this utility model is to provide a kind of refining furnace electrode locating device, avoids or reduces the electrode horizontal-shift, reduces number of times and the time of adjusting fastening bolt, improves the operating rate of refining furnace.
The refining furnace electrode locating device comprises that oil cylinder is connected with column, bearing is established in the column upper end, conductive cross arm is by being bolted on the bearing, conductive cross arm is held terminal clamp, the electrode band-type brake of establishing holding electrode in addition, be characterized in that bearing is provided with location-plate in pairs along the conductive cross arm both sides, it is corresponding with it that insulation board is established in the conductive cross arm both sides, and conductive cross arm is closely tied in the location-plate of paired setting.Insulation board makes between charged transverse arm and the column and insulate.Conductive cross arm this by being bolted on the bearing, the location-plate that adds the setting of fixing bearing both sides more tightly roof pressure conductive cross arm, conductive cross arm and column just link together securely like this.In smelting process, when imbalance appearred in three-phase current, conductive cross arm and column were connected firmly, and stoped electrode to produce horizontal-shift.
The utility model further improves, and location-plate is connected and composed by dihedral plate and pressing plate, and pressing plate is established through hole; Dihedral plate inboard is the right angle, and following right-angle side is fixed on the side of bearing, and last right-angle side is connected with pressing plate, and roof pressure is on insulation board, conductive cross arm.
Fastening, firm for conductive cross arm is connected with bearing, the location-plate more than two pairs is set on the bearing at least.
Insulation board is fixed on the pressing plate inboard by stainless steel bolt.
Compared with prior art, advantage is novel, and is simple and reasonable for structure; Conductive cross arm and column are connected firmly, and bolt is difficult for loosening, have thoroughly solved the difficult problem of conductive cross arm horizontal-shift, significantly reduce number of times and the time of adjusting bolt, reduce the unplanned off-time, have improved the operating rate of refining furnace; Also avoid because of puncturing bell, the loss that lead rupture causes.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a refining furnace electrode locating device structural representation.
Fig. 2 is the location-plate front view.
Fig. 3 is the location-plate side view.
The specific embodiment
As seen from Figure 1, the refining furnace electrode locating device is made up of oil cylinder 1, column 2, conductive cross arm 7, terminal clamp 8, electrode band-type brake 9, oil cylinder 1 is connected with column 2, bearing 3 is established in column 2 upper ends, establish through hole on the bearing 3, conductive cross arm 7 is established screw, by bolt 4 conductive cross arm 7 is fixed on the column 2; Conductive cross arm 7 other ends are established the terminal clamp 8 and the electrode band-type brake 9 of holding electrode 10.Two pairs of location-plates 5 of both sides welding of bearing 3, insulation board 6 is established in the both sides of conductive cross arm 7, and is corresponding with the location-plate 5 that bearing 3 is established, and conductive cross arm 7 fits closely in the location-plate 5 of paired setting, conductive cross arm 7 is carried out the side fix, conductive cross arm 7 is connected more firm with column 2.In the refining production process,, start oil cylinder 1,10 liftings of column 2 drive electrodes according to smelting requirements, when imbalance appears in three-phase current, column 2 and conductive cross arm 7 have sufficient intensity, stop electrode 10 horizontal-shifts, have avoided electrode 10 directly to contact with water cooled cover.
By Fig. 2-3 as can be seen, dihedral plate 11 inboards present the right angle, and 14 side welds of following right angle are connected on the both sides of bearing 3, and last right-angle side 13 is corresponding with insulation board 6, make between conductive cross arm 7 and the column 2 and insulate.
