Abstract
The utility model discloses a kind of metallurgical furnaces, including furnace body and the protective layer being arranged on inboard wall of furnace body, it is provided with sealing cover above the furnace body, the protective layer outside-in is disposed with metal fixed jacket, heat insulation layer, heating device layer and crucible, it is vertically installed with plunger type switch valve in the middle part of the crucible, plunger type switch valve bottom end is provided with runner system, the crucible, plunger type switch valve, runner system is the ceramics of thermostable, and it is filled with inert gas when working, the resistance to each layer of the metallurgical furnace is all made of thermostable ceramics, it is heat-resist, service life is long.And metal fixed jacket, heat insulation layer can obstruct the heat transfer of metallurgical furnace chamber to the outer wall of metallurgical furnace well, prevent the inner wall temperature of metallurgical furnace from losing.
Description
Technical field
The utility model is related to metallurgical technology field, more particularly to a kind of metallurgical furnace.
Background technology
Metallurgical furnace is smelter, and especially the main steelmaking equipment of steel production enterprise, furnace body in use may be used
Energy meeting furnace body temperature is excessively high, damages furnace body.Since metallurgical furnace internal structure is complicated, once furnace body damages, maintenance difficulty is big, repairs
It is of high cost, seriously affect the progress normally produced.In addition temperature is easy loss when metallurgical, and metallurgical in-furnace temperature is inaccurate, influences
The quality of metallurgical finished product.
Utility model content
To overcome the problems, such as that metallurgical furnace heat resistance existing in the prior art is not high, the utility model provides a kind of metallurgy
Stove.
Specific technical solution is as follows：
A kind of metallurgical furnace, including furnace body and the protective layer being arranged on inboard wall of furnace body, the furnace body top is provided with sealing
Lid, the protective layer outside-in is disposed with metal fixed jacket, heat insulation layer, heating device layer and crucible, described
It is vertically installed with plunger type switch valve in the middle part of crucible, plunger type switch valve bottom end is provided with runner system, the crucible, column
Plug switch valve, runner system are the ceramics of thermostable.
Preferably, the sealing cap upper surface is provided with air inlet, and inert gas is filled in the air inlet.
Preferably, the area being open on the crucible is more than crucible base area.
The utility model has the advantages that compared with prior art：
(1) crucible in the utility model, plunger type switch valve, runner system are formed by the ceramic making of thermostable
And crucible using when protected filled with inert gas, effectively increase the heat resistance of metallurgical furnace, substantially increase metallurgical furnace
Service life.
(2) the metal fixed jacket in the utility model, heat insulation layer can obstruct the heat biography of metallurgical furnace chamber well
It is delivered to the outer wall of metallurgical furnace, prevents the inner wall temperature of metallurgical furnace from losing.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of metallurgical furnace of the utility model；
In figure, 1- sealing covers, 2- metal fixing sleeves, 3- heat insulation layers, 4- heating device layers, 5- crucibles, 6- plunger types switch
Valve, 7- runner systems.
Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
The utility model discloses a kind of metallurgical furnace, including furnace body and the protective layer that is arranged on inboard wall of furnace body, such as Fig. 1 institutes
Show, sealing cover 1 is provided with above furnace body, and protective layer outside-in is disposed with metal fixed jacket 2, heat insulation layer 3, adds
Thermal layer 4 and crucible 5,5 middle part of crucible are vertically installed with plunger type switch valve 6, and 6 bottom end of plunger type switch valve is provided with running channel
System 7,1 top of sealing cover are provided with air inlet, inert gas are filled in air inlet.Preferably, it is open on the crucible
Area is more than crucible base area.The selection of inert gas can be selected according to the material in metallurgical furnace.Further preferably
, crucible 5, plunger type switch valve 6 and runner system 7 are all made of the ceramics of thermostable.Crucible 5 in the utility model,
It is carried out filled with inert gas when plunger type switch valve 6, runner system 7 are formed by the ceramic making of thermostable and crucible uses
Protection, effectively increases the heat resistance of metallurgical furnace, substantially increases the service life of metallurgical furnace, and metal fixed jacket 2, thermal insulation
Layer 3 can obstruct the heat transfer of metallurgical furnace chamber to the outer wall of metallurgical furnace well, prevent the inner wall temperature of metallurgical furnace from losing.
The embodiment of the utility model is explained in detail above in association with attached drawing, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the scope of protection of the utility model.
