Abstract
The utility model relates to a steelmaking electric arc furnace. Current electric stove electric stove cover elevating system exists all that equipment repair and maintenance is inconvenient, the accident rate is high, the defect of blowing out repair time overlength, and the influence is smelted, causes steelmaking production decline and running cost increase. The utility model discloses a bell level sets up, and connecting bolt and vertical bell elevating system rigid connection are passed through to one end, bell elevating system is fixed in the electric pole fluctuation frame, and electric pole fluctuation frame internal fixation has the bell lift cylinder who is used for driving the bell lift. The utility model discloses bell lift operating mode requirement when the electric stove satisfies the electric stove smelting has reduced manufacturing and maintenance cost, the structure is succinct, and the bell goes up and down steadily, and lift cylinder keeps away from the high -temperature region, the life -time dilatation, and the accident rate is low, and the reliability is high, has improved productivity ratio. Simultaneously, the bell top does not have other equipment, and relatively more succinct, the operating space increases, and it is convenient that the bell use is changed.
Description
Technical field
This utility model is related to a kind of metallurgical equipment and in particular to a kind of electric furnace arrangement for producing steel.
Background technology
Mainly there is in the following manner in the furnace cover lifting mechanism of steel-smelting electric furnace both at home and abroad at present：Electric arc furnace → furnace cover lifting mechanism →
The 4 points of hangings of bell top chain；Furnace cover lifting mechanism adopts the hanging of 4 points of bell top chain, elevating mechanism by 2 hydraulic cylinders,
Drag link mechanism, synchronizing shaft, chain etc. are constituted.The above-mentioned component of composition furnace cover lifting mechanism is installed on Г ellbeam after being coupled to each other
On, furnace cover lifting motion is realized by oil cylinder.
This kind of mode has the disadvantage that：1. junction point is many, and accident point is also many；2. furnace cover lifting oil cylinder from furnace shell too close to, ring
Border temperature is higher, easily causes lift cylinder because of the too high service life reduction of temperature；3. pass through 4 chains and hang bell, need to increase
Plus synchronizing shaft, in the case that bell is laid particular stress on, it is larger that synchronizing shaft bears moment of torsion, is in high-temperature region, synchronizing shaft is yielding, causes again
Motion fault；4. chain is connected with bell and Г ellbeam and belongs to " flexible " connection, and bell is also easy to produce in lifting process and rocks, with
Electrode friction is even collided, thus lesion electrode；5. there are Г ellbeam and drive mechanism above bell, bell changes loaded down with trivial details, operation
Space is less.
At present in the electric furnace furnace lid elevating mechanism using, all there is equipment repair and maintenance inconvenience, or accident rate be high,
Shutdown maintenance overlong time, impact is smelted, and causes to make steel yield decline and operating cost increases.
Content of the invention
The purpose of this utility model is to provide a kind of electric furnace arrangement for producing steel, effectively reduces electric furnace and makes and maintenance cost, increases
Furnace cover lifting mechanism service life.
The technical scheme that this utility model is adopted is：
A kind of electric furnace arrangement for producing steel, including bell it is characterised in that：
Bell is horizontally disposed with, and one end is rigidly connected with vertical furnace cover lifting mechanism by connecting bolt；
Rise fall of electrodes frame is fixed in furnace cover lifting mechanism, is fixed with for driving furnace cover lifting in rise fall of electrodes frame
Furnace cover lifting oil cylinder.
Furnace cover lifting mechanism is the 4th column offset structure.
Furnace cover lifting oil cylinder is located at below furnace cover lifting mechanism, and furnace cover lifting mechanism is single hydraulic cylinder jacking type.
Bell one end is provided with rigid frame, and rigid frame edge is welded with adpting flange, and rise fall of electrodes frame top sets
It is equipped with corresponding adpting flange, the two adpting flange relatively, is fixed by connecting bolt phase.
This utility model has advantages below：
This utility model electric furnace meets furnace cover lifting working condition requirement during electric furnace smelting, can meet use requirement, drops again
Low manufacture and maintenance cost；Simple for structure, steadily, hoist cylinder is away from high-temperature region, life, accident rate for furnace cover lifting
Low, reliability is high, improves productivity ratio.Meanwhile, there is no miscellaneous equipment above bell, relatively more succinct, working place increases, stove
Lid is convenient using changing.

Specific embodiment
With reference to specific embodiment, this utility model is described in detail.
A kind of electric furnace arrangement for producing steel that this utility model is related to, including bell 1, bell 1 is horizontally disposed with, and one end is passed through to connect spiral shell
Bolt 3 is rigidly connected with vertical furnace cover lifting mechanism 2.Rise fall of electrodes frame 4, electrode positioning mechanism are fixed in furnace cover lifting mechanism 2
It is fixed with the furnace cover lifting oil cylinder 5 for driving bell 1 lifting in frame 4.Furnace cover lifting mechanism 2 is the 4th column offset knot
Structure.Furnace cover lifting oil cylinder 5 is located at below furnace cover lifting mechanism 2, and furnace cover lifting mechanism 2 is single hydraulic cylinder jacking type.
Referring to Fig. 1 and Fig. 2, bell 1 is provided with connection rigid frame, and frame ends are welded with adpting flange, furnace cover lifting
Mechanism 2 is again provided with adpting flange, and by connecting bolt 3, the two links together；Referring to Fig. 3 and Fig. 4 furnace cover lifting mechanism 2
It is welded as entirety with rise fall of electrodes frame 4, as the bearing structure of furnace cover lifting mechanism 2, furnace cover lifting oil cylinder 5 is installed on bell
The steady elevating movement of bell inside elevating mechanism 2, is realized by oil cylinder.
Content of the present utility model is not limited to cited by embodiment, and those of ordinary skill in the art pass through to read this practicality newly
Type description and any equivalent conversion that technical solutions of the utility model are taken, are claim institute of the present utility model
