Description
Technical field
The utility model belongs to steelmaking technical field, 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-conserving and environment-protective are one of maximum driving forces of promoting technological progress, such as patent
CN105202907A, by using high-temperature flue gas preheating scrap, reaches the purpose of energy-conservation.In the above-mentioned technical solutions, to open
Scrap preheater need to be moved a segment distance to the direction away from electric arc furnaces during bell, concede the space of bell rotary oscillation.
This design device structure is complicated, cumbersome, and bell arm length, adds the load of hoisting mechanism, therefore the skill
Art is not suitable for outwarding winding bell charging.But the steel scrap of some in actual production, such as heavy-duty waste steel, it is impossible to filled by scrap steel preheating
Put in addition stove and be directly added into, it is necessary to open bell in stove.
Utility model content
In view of this, the purpose of this utility model is the cover-opening structure for providing scrap steel preheating type electric arc furnaces, and the structure is beaten
Open and close closed furnace lid is simple and convenient, without mobile scrap preheater when bell is opened, whole body of heater seal when bell is closed
It is good.
To reach above-mentioned purpose, the utility model is achieved through the following technical solutions：
A kind of cover-opening structure for scrap steel preheating type electric arc furnaces that the utility model is provided, including body of heater, bell, scrap steel preheating
Device and ring body, the ring body are arranged on above body of heater, and ring body is fixedly connected with body of heater, constitute steel scrap filler interface, with giving up
Steel preheating device is connected；The steel scrap filler interface has the perpendicular for the axis that fascinated perpendicular to body of heater, for adapting to body of heater
Any operation of fascinating；The ring body is provided with the sealing surface matched with bell away from the side of scrap preheater, is used for
Operation is arranged in the rotation for adapting to bell, and is tightly engaged into when bell is closed by the sealing surface with ring body formation.
Further, the sealing surface is inclined-plane, is intersected with the upper plane of body of heater, and its incline direction is towards scrap preheater
Side is tilted upward.
Further, the sealing surface is cambered surface, and it is axially parallel with the perpendicular of steel scrap filler interface.
Further, the cambered surface is cancave cambered surface.
Compared with prior art, Advantageous Effects of the present utility model are：
1) body of heater can arbitrarily fascinate during normal smelting, not limited by scrap preheater；
2) open when bell feeds without mobile scrap preheater；
3) bell is opened, closes simple and convenient, whole electric arc furnaces good leak tightness close with body of heater cooperation.
Other advantages of the present utility model, target and feature will be explained in the following description to a certain extent
State, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or
Person can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be said by following
Bright book is realized and obtained.
Brief description of the drawings
In order that the purpose of this utility model, technical scheme and advantage are clearer, below in conjunction with accompanying drawing to this practicality
It is new to be described in further detail, wherein：
Fig. 1 is by side wall charging schematic diagram；
Fig. 2 is opening bell charging schematic diagram；
Fig. 3 is another schematic diagram fed by side wall；
Fig. 4 is Fig. 3 partial top view.
Reference：1- bodies of heater, 2- bells, 3- scrap preheaters, 4- ring bodies, 5- steel scrap filler interfaces, 6- sealing surfaces,
7- expects basket.
Embodiment
Below with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail；It should be appreciated that it is preferred that real
Example is applied only for explanation the utility model, rather than in order to limit protection domain of the present utility model.
As shown in Figure 1, 2, this preferred embodiment includes body of heater 1, bell 2, scrap preheater 3, ring body 4, and the ring body 4 is pacified
Mounted in the top of body of heater 1, it is fixedly connected with body of heater 1, ring body 3 and the composition steel scrap of body of heater 1 filler interface 5, the steel scrap filler interface 5
It is connected with scrap preheater 3, it has the perpendicular for the axis that fascinated perpendicular to body of heater 1；The ring body 4 is filled away from scrap steel preheating
The side for putting 3 is provided with the sealing surface 6 matched with bell 2, and the sealing surface 6 is inclined-plane, is intersected with the upper plane of body of heater 1, its
Incline direction is to be tilted upward towards the side of scrap preheater 3.So, bell 2 is engaged (Fig. 1) with ring body 4 by inclined-plane, in advance
Steel scrap after heat is added in stove by steel scrap filler interface 5, and body of heater, which need to fascinate, during smelting the technological operation such as is slagged tap, tapped,
The perpendicular of the steel scrap filler interface 5 can well adapt to any operation of fascinating of body of heater 1 so that scrap preheater 3 is not
Body of heater can be influenceed to fascinate；When open bell 2 feed when (Fig. 2), bell 2 lifted a segment distance be it is rotatable arrange, 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 in situ and pass of landing
When closing, it constitutes close cooperation by inclined-plane and ring body 4, it can be seen that the nothing of scrap preheater 3 during whole 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, made up
The deficiency of original technology.
In another embodiment, as shown in Figure 3,4, the sealing surface 6 is cambered surface, its axial direction and steel scrap filler interface 5
Perpendicular is parallel.So, bell 2 is coordinated by cambered surface with ring body 4, have the advantage that can not be lifted or only lifting it is one small
Segment distance, bell 2 just can rotate and arrange, without being interfered with body of heater 1, ring body 4 etc..It is preferred that, the cambered surface is concave arc
Face.So, operation is arranged beneficial to rotation of the bell 2 when opening.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent, and without departing from the objective and scope of the technical program, it all should
Cover among right of the present utility model.
