Description
Technical field
The present invention relates to electric furnace arrangement for producing steel technical field, more particularly to a kind of molten steel with plug-in insulation construction
Bag.
Background technology
Steel ladle is used for steel mill, molten steel is accepted before open hearth, electric furnace or converter by Foundry Works, carries out pouring practice.At present
The insulation of steel ladle is made steel mainly by a global design of steel ladle internally structure, using internal insulation knot
Structure, after certain time, the insulation material such as refractory brick or fire clay changes, and heat-insulating property reduces, but due to being overall
Structure, inconvenience is safeguarded, can not also adapt to the change of frequent transitions and northern extreme weather of steel making working procedure to the temperature drop of steel ladle
Control requires, it is thus proposed that a kind of plug-in steel ladle of insulation construction, its structure are about being all provided with the ectonexine of former steel ladle
Put flame retardant coating or heat-insulation layer, but this structure due to the connection of flame retardant coating, heat-insulation layer and steel ladle it is insecure, and steel ladle works
When carrying molten steel reach tens of tons, therefore flame retardant coating and heat-insulation layer are easy to come off, it is impossible to long-term use.
The content of the invention
The present invention is above-mentioned in order to overcome the shortcomings of, there is provided a kind of steel ladle with plug-in insulation construction, including molten steel
Bag body, steel ladle body bottom surface top are provided with bearing plate, and the edge of the bearing plate is connected with the inwall of steel ladle body, held
First thermal insulation layer and the first heat-insulation layer are sequentially provided between weight plate and steel ladle bottom surface, bearing plate is provided with inner barrel, inner barrel
Outer cladding second thermal insulation layer, is provided with the second heat-insulation layer between second thermal insulation layer and steel ladle body, steel ladle bodies top is removable
Unload and be connected with annular cover plate, the top edge of the annular cover plate covering steel ladle body, removable lower ring cover when safeguarding, change
Second thermal insulation layer and the second heat-insulation layer.
Preferably, some stiffening rings are arranged with outside the steel ladle body.
Preferably, the stiffening ring is axially uniformly distributed along steel ladle body.
Preferably, the first thermal insulation layer and second thermal insulation layer are made by high temperature resistant mica.
Preferably, first heat-insulation layer and the second heat-insulation layer are spliced by refractory brick.
The beneficial effects of the invention are as follows：The present invention is reasonable in design, simple in construction, and thermal insulation layer and heat-insulation layer are tightly embedded in by steel
The enclosure interior that water bag body, inner barrel, bearing plate and annular cover plate are formed, molten steel pressure during work are held by overall structure
Load, heat-insulation layer and thermal insulation layer are not damaged, and easy to maintenance, and insulation is reliable.
Brief description of the drawings
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein：
Fig. 1 is the structural representation of the present invention；Fig. 2 is the overlooking the structure diagram of the present invention；
Fig. 3 is the cutting plane schematic diagram of A-A in Fig. 1.
Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
As Figure 1-3, the present invention is a kind of steel ladle with plug-in insulation construction, including steel ladle body 1, molten steel
Bearing plate 2 is provided with above the bottom surface of bag body 1, the edge of the bearing plate 2 connects with the inwall of steel ladle body 1, the He of bearing plate 2
It is sequentially provided with the heat-insulation layer 4 of first thermal insulation layer 3 and first between steel ladle bottom surface, bearing plate 2 is provided with inner barrel 5, outside inner barrel 5
Second thermal insulation layer 6 is coated, the second heat-insulation layer 7 is provided between second thermal insulation layer 6 and steel ladle body 1, the top of steel ladle body 1 can
Dismantling connection has annular cover plate 8, and the annular cover plate 8 covers the top edge of steel ladle body 1.
Some stiffening rings 9 are arranged with outside the steel ladle body 1.
The stiffening ring 9 is axially uniformly distributed along steel ladle body 1.
The first thermal insulation layer 3 and second thermal insulation layer 6 are made by high temperature resistant mica.
The heat-insulation layer 7 of first heat-insulation layer 4 and second is spliced by refractory brick.
The present invention is reasonable in design, simple in construction, and thermal insulation layer and heat-insulation layer are tightly embedded in by steel ladle body, inner barrel, held
The enclosure interior that weight plate and annular cover plate are formed, molten steel pressure during work are undertaken by overall structure, and heat-insulation layer and thermal insulation layer are not
It is damaged, and it is easy to maintenance, insulation is reliable.
Above-mentioned according to the present invention is enlightenment, by above-mentioned description, relevant staff completely can without departing from
In the range of this invention technological thought, various changes and amendments are carried out.The technical scope of this invention is not limited to
In the content on specification, it is necessary to determine its technical scope according to right.
