Description
Technical field
The invention belongs to steelmaking technical fields, and in particular to a kind of cover-opening structure of scrap steel preheating type electric arc furnaces.
Background technology
In electric-arc furnace steelmaking field, energy conservation and environmental protection is one of maximum driving force of promoting technological progress, such as patent
CN105202907A reaches energy-efficient purpose by using high-temperature flue gas preheating scrap.In the above-mentioned technical solutions, it to open
Scrap preheater need to be moved a distance to the direction far from electric arc furnaces when bell, concede the space of bell rotary oscillation.
This design method device structure is complicated, cumbersome, and bell arm length, increases the load of hoisting mechanism, therefore the skill
Art is not suitable for unscrewing bell charging.But some steel scrap, such as heavy-duty waste steel in actual production, can not be filled by scrap steel preheating
It sets and is added in stove, opening bell is needed to be directly added into stove.
Invention content
In view of this, the purpose of the present invention is to provide the cover-opening structure of scrap steel preheating type electric arc furnaces, which plays open and close
Closed furnace lid is simple and convenient, without mobile scrap preheater, bell entire furnace body good leak tightness when closing when bell is opened.
In order to achieve the above objectives, the present invention is achieved through the following technical solutions：
A kind of cover-opening structure of scrap steel preheating type electric arc furnaces provided by the invention, including furnace body, bell, scrap preheater
And ring body, the ring body is arranged above furnace body, and ring body is fixedly connected with furnace body, forms steel scrap filler interface, pre- with steel scrap
Thermal is connected；The steel scrap filler interface has the perpendicular for the axis that fascinates perpendicular to furnace body, for adapting to appointing for furnace body
Meaning is fascinated operation；The ring body is provided with the sealing surface to match with bell away from the side of scrap preheater, for adapting to
Operation is arranged in the rotation of bell, and is tightly engaged by the sealing surface and ring body formation when bell is closed.
Further, the sealing surface is inclined-plane, is intersected with the upper plane of furnace body, and inclined direction is towards scrap preheater
Side tilts upward.
Further, the sealing surface is cambered surface, axial parallel with the perpendicular of steel scrap filler interface.
Further, the cambered surface is cancave cambered surface.
Compared with prior art, the method have the benefit that：
1) furnace body can arbitrarily fascinate when normal smelting, not limited by scrap preheater；
2) without mobile scrap preheater when opening bell charging；
3) bell is opened, closes simple and convenient, entire electric arc furnaces good leak tightness close with furnace body cooperation.
Other advantages, target and the feature of the present invention will be illustrated in the following description to a certain extent, and
And to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, Huo Zheke
To be instructed from the practice of the present invention.The target and other advantages of the present invention can by following specification realizing and
It obtains.
Description of the drawings
To make the objectives, technical solutions, and advantages of the present invention clearer, below in conjunction with attached drawing to the present invention make into
The detailed description of one step, wherein：
Fig. 1 is to be fed schematic diagram by side wall；
Fig. 2 is to open bell charging schematic diagram；
Fig. 3 is another schematic diagram to be fed by side wall；
Fig. 4 is the partial top view of Fig. 3.
Reference numeral：1- furnace bodies, 2- bells, 3- scrap preheaters, 4- ring bodies, 5- steel scrap filler interfaces, 6- sealing surfaces,
7- expects basket.
Specific implementation mode
Below with reference to attached drawing, the preferred embodiment of the present invention is described in detail；It should be appreciated that preferred embodiment
Only for illustrating the present invention, the protection domain being not intended to be limiting of the invention.
As shown in Figure 1, 2, this preferred embodiment includes furnace body 1, bell 2, scrap preheater 3, ring body 4, the ring body 4 peace
It mounted in the top of furnace body 1, is fixedly connected with furnace body 1, ring body 3 forms steel scrap filler interface 5, the steel scrap filler interface 5 with furnace body 1
It is connected with scrap preheater 3, there is the perpendicular for the axis that fascinates perpendicular to furnace body 1；The ring body 4 is filled away from scrap steel preheating
The side for setting 3 is provided with the sealing surface 6 to match with bell 2, which is inclined-plane, is intersected with the upper plane of furnace body 1,
Inclined direction is to be tilted upward towards 3 side of scrap preheater.In this way, bell 2 matches (Fig. 1) with ring body 4 by inclined-plane, in advance
Steel scrap after heat is added by steel scrap filler interface 5 in stove, and furnace body, which need to fascinate, when smelting the technological operations such as is slagged tap, is tapped,
The perpendicular of the steel scrap filler interface 5 can well adapt to the arbitrary operation of fascinating of furnace body 1 so that scrap preheater 3 is not
Furnace body can be influenced to fascinate；When opening bell 2 and feeding (Fig. 2), bell 2 promotes a distance, that is, rotatable and arranges, will not be with stove
Body 1, ring body 4 collide interference, steel scrap are directly added into stove using material basket 7, then bell 2 swings back original position and pass of landing
When closing, close cooperation is constituted by inclined-plane and ring body 4, it can be seen that 3 nothing of scrap preheater during entire charging
Need any action.Pass through this mode of operation, you can the steel scrap of the unsuitable preheating such as heavy-duty waste steel is directly added into stove, is made up
The deficiency of original technology.
In another embodiment, as shown in Figure 3,4, the sealing surface 6 is cambered surface, axial and steel scrap filler interface 5
Perpendicular is parallel.In this way, bell 2 is coordinated by cambered surface and ring body 4, having the advantage that can not be promoted or only to promote one small
Segment distance, bell 2, which can rotate, to be arranged, without being interfered with furnace body 1, ring body 4 etc..Preferably, the cambered surface is concave arc
Face.In this way, arranging operation conducive to rotation of the bell 2 when opening.
Finally illustrate, the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although with reference to compared with
Good embodiment describes the invention in detail, it will be understood by those of ordinary skill in the art that, it can be to the skill of the present invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of the technical program, should all be covered in the present invention
Right in.
