Abstract
The utility model discloses a crystallizer protecting device, which belongs to a protecting device and comprises a crystallizer, wherein a protecting cover is arranged above the crystallizer, a gas spray ring is arranged in the protecting cover, spray nozzles are uniformly distributed on the gas spray ring, and the gas spray ring is connected with a gas source interface. The crystallizer protecting device has the advantages that the structure is simple, and simultaneously, good sealing performance is realized.
Description
Technical field
The utility model belongs to a kind of protector, is specifically related to a kind of mold protector.
Background technology
Along with the steel fast development of China, the continuous progress of smelting technology, most of steel mills begin widely-used electric slag refusion and smelting technology and begin to produce rectangular slab such as high-end military project, nuclear appearance.The esr slab is to make slag produce heat with fusing rectangle consumable electrode through short net; Make it form molten drop; Molten drop passes slag bath and gets into metal pool, and in that cooling forms steel ingot through water mold, the removal of its detrimental impurity is to utilize that molten drop forms, the series of physical chemical reaction will take place between the metal in the drippage process in the metal pool and the slag; Its main sfgd. has only one deck liquid slag to completely cut off metal pool and ambient atmosphere; The hydrogen of a part of molten steel, the increasing amount of nitrogen and the secondary oxidation of steel can be reduced, but, its requirement can't be reached for the higher steel grade of quality requirements.For further having reduced the possibility of the secondary oxidation that increases hydrogen, nitrogen pick-up and steel, need outside mold, increase a kind of gas device and come further to play the effect that is hedged off from the outer world.
But the esr slab does not also use special-purpose protective guard at present; All are some dust excluding hoods; Often do not reach the specification of quality of high-end product owing to the internal soundness of gas content (oxygen, nitrogen, hydrogen etc.) in the steel and initiation thus; And because the mold character and the structure walking manner of electroslag slab and electroslag circle base have bigger difference, the inapplicable electroslag rectangular slab of mold protective guard of therefore round base.
Summary of the invention
The purpose of the utility model is to address the above problem and a kind of mold protector is provided, and this apparatus structure is simple, has excellent sealing performance simultaneously.
The technical scheme that the utility model adopted is:
A kind of mold protector comprises mold, and said mold top is equipped with protective guard, is provided with jet ring in the said protective guard, uniform distribution nozzle on the said jet ring, and said jet ring links to each other with gas source interface.
Further, said jet ring is along the setting of protective guard inwall.
Further, said protective guard is installed in the mold top through joint bolt.
Preferably, the quantity of said joint bolt is four.
Preferably, said protective guard is shaped as the rectangle cylindrical shell.
Further, said protective guard is the upper and lower opening structure.
Preferably, said jet ring is an open tube, and its material is a copper.
Further, the quantity of said jet ring is two-layer.
Further, said nozzle becomes 15～25 ℃ of angles with the protective guard inwall.
Further, said gas source interface is installed in the protective guard outer wall.
The utlity model has following advantage:
(1) structure with make very simply, and manufacturing cost and maintenance cost are far below other protective guards;
(2) protective guard and mold link together, and can move up and down along with mold, and be more remarkable than the sealing property of other devices;
(3) two all ventpipes are installed on the protective guard inwall, it is relative that its air supply source distributes, and can prevent away from source of the gas place orifice gas pressure problem on the low side, and two all ventpipes interact and can guarantee to spray gas pressure balancing;
(4) contain two all ventpipes on the protective guard inwall, can be according to smelting the different kinds that change shielding gas of steel grade;
(5) method for arranging of its nozzle can make and spray into gas along a sealing of same direction formation compression ring, can be issued to sealing effect preferably by very low again gaseous tension.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
The front view of a kind of mold protector that Fig. 1 provides for the utility model embodiment;
The vertical view of a kind of mold protector that Fig. 2 provides for the utility model embodiment.
Embodiment
See figures.1.and.2, this device mainly comprises mold 5, and mold 5 tops are fixing with protective guard 1 through four joint bolts 6.Protective guard 1 be shaped as the rectangle cylindrical shell, be the upper and lower opening structure, be the cover body of a water-cooled.Protective guard 1 links together with mold 5, plays motion with one of which, because the light mold 5 of can not giving of material brings any influence, belongs to dynamic protective guard.Along protective guard 1 inwall two-layer jet ring 2 is installed; Jet ring 2 is an open tube; The material of open tube is a copper, and this jet ring 2 first can prevent the problem away from the decay of source of the gas place nozzle 3 gaseous tensions, and two-layer jet ring 2 interacts and can guarantee to spray gas pressure balancing; Second can be according to smelting the steel grade difference switch protecting gaseous species.Uniform distribution nozzle 3 on the jet ring 2; Nozzle 3 becomes 15～25 ℃ of angles with protective guard 1 inwall; Nozzle 3 becomes 25 ℃ of angles with protective guard 1 inwall in the present embodiment; The gas that the layout type of nozzle 3 is convenient to spray produces coflow, so that between protective guard inwall and consumable electrode, form air curtain, so just can make the molten steel in mold and the external world reach isolated fully.Jet ring 2 links to each other with gas source interface 4, and gas source interface 4 is installed in protective guard 1 outer wall.
When the work of this device; This device is installed on the mold 5; Play motion or static with one of which, select the shielding gas kind to be connected on the gas source interface 4 and open air supply valve according to smelting the steel grade demand, gas is through nozzle 3 ejections; Between protective guard 1 and consumable electrode 7, form the air curtain that has certain pressure, make the mold 5 interior molten steel and the external world reach isolated.
It should be noted last that; Above embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to preferred embodiment the present invention is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention; And not breaking away from the spirit and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
