Description
Technical field
The utility model relates to a kind of teapot-type ladle for LF refining furnace, belong to metallurgical steelmaking equipment technical field.
Background technology
Existing LF ladle refining furnace splashes to prevent heat radiation and molten steel, and must cover a steel ladle cover above ladle, so LF stove ladle generally arranges a slide gate nozzle in bottom, open sliding nozzle device during cast by artificial or hydro-cylinder, molten steel flows out.This ladle is suitable only for directly upper curved type continuous caster or casting massive casting (the disposable casting of molten steel is complete).
In order to light casting of casting, molten steel must be poured again into the ladle of band stopper rod device, following several respects consequence can be produced like this: molten steel 1) can be caused to lower the temperature; 2) molten steel also can be caused to contact with air simultaneously, cause secondary pollution, the refined molten steel quality of refining furnace is greatly affected; 3) ladle and refractory materials quantity can be increased, thus cause production cost to improve; 4) the ladle-to-ladle process of molten steel can produce that sparks fly off molten steel, there is potential safety hazard.
Summary of the invention
The utility model proposes a kind of teapot-type ladle for LF refining furnace, its object is intended to overcome the defect that traditional LF refining furnace is not suitable for watering light casting.
Technical solution of the present utility model: for the teapot-type ladle of LF refining furnace, is characterized in that, in teapot shape, one sidewall being established the tap hole of a spout of a teapot shape, being plugged with stopper rod in this tap hole, 8-12 ° centroclinal with ladle; Correspondingly with stopper rod be provided with the quick extraction mechanism of stopper rod.
Advantage of the present utility model: while 1) meeting liquid steel refining, possesses again the feature of rod type ladle, is convenient to water light casting, can realize repeatedly connecting water when pouring into a mould light casting; 2) be designed with and special tear lever apparatus of drawing the cork open, operation is easy; 3) ladle-to-ladle without the need to other secondary, refining ladle unites two into one with cast ladle, saves production cost, simplifies steel-smelting production process; 4) molten steel can not reducing temperature twice, by secondary oxidation, can not can not increase other fringe costs.

Embodiment
As shown in Figure 1, for the teapot-type ladle of LF refining furnace, its structure is teapot shape, one sidewall is established the tap hole of a spout of a teapot shape, is plugged with stopper rod 4 in this tap hole, 8-12 ° centroclinal with ladle 3; Correspondingly with stopper rod 4 be provided with the quick extraction mechanism of stopper rod.
The LF refining furnace that teapot-type ladle of the present invention is housed, except possessing the structure unit (comprising conductive cross arm, column, bell, furnace cover lifting device, buggy ladle, short net etc.) of common LF refining furnace, also needs to arrange the quick extraction mechanism 6 of a set of stopper rod for extracting stopper rod 4.
As shown in accompanying drawing 3-1 ~ 3-3, the quick extraction mechanism 6 of stopper rod, its structure comprises frames 7, stopper rod plug hydro-cylinder 8, stopper rod plug column 9, positioning guide pulleys 10, mechanical hand hydraulic cylinder 11, mechanical manipulator 12, catch amis 13, expansion link 14 and spring device 15; It is wherein expansion link 14 in catch amis 13, the front end of this expansion link 14 is connected with mechanical manipulator 12, the rear end of expansion link 14 is connected with the front end of spring device 15, the rear end of this spring device 15 is connected with mechanical hand hydraulic cylinder 11, the upper end that bottom and the stopper rod of catch amis 13 plug column 9 is connected, stopper rod plug column 9 is in frames 7, it is stopper rod plug hydro-cylinder 8 in the middle of stopper rod plug column 9, this stopper rod plug hydro-cylinder 8 is connected with frames 7, and the middle part of stopper rod plug column 9 is connected with frames 7 by positioning guide pulleys 10.
Because stopper rod and ladle center approximately tilt about 10 °, therefore stopper rod plug column 9 also should be consistent with this angle, ensures that stopper rod is extracted smoothly, and described stopper rod plug column 9 angle of inclination is also about about 10 °.
Even if stopper rod 3 also can be extracted for ensureing that stopper rod 3 position has during deviation by described positioning guide pulleys 10 smoothly; Mechanical hand hydraulic cylinder 11, expansion link 14 and spring device 15 are for opening or firmly grasping mechanical manipulator 12.
During cast, molten steel directly flows out from Ladle Bottom side tap hole, thus in casting cycle, can effectively prevent slag liquid to be mixed in foundry goods, does not also need again ladle-to-ladle simultaneously.
During LF refining, tap hole stopper rod 4 clogs, and now whole Baogang water can both carry out refining treatment.
After refining, buggy ladle 5 years ladles 3 walk to quick extraction mechanism 6 side of stopper rod.Now give mechanical hand hydraulic cylinder 5 fuel feeding, the piston rod of hydro-cylinder stretches out, compression spring mechanism 15, cause expansion link 14 to protracting, thus mechanical manipulator 12 opens, as shown in accompanying drawing 3-1.Again buggy ladle 5 is gone, allow stopper rod 4 enter mechanical manipulator 12 and grasp within scope.Then close the valve of mechanical hand hydraulic cylinder 5, spring device 15 restores automatically, and expansion link 14 pulls back, and causes mechanical manipulator 12 to firmly grasp stopper rod 4.
Now, then to stopper rod plug hydro-cylinder 8 fuel feeding, allow stopper rod plug hydro-cylinder 8 plug column 9 under the effect of positioning guide pulleys 10 with stopper rod, driving mechanical hand 12 and stopper rod 4 promote smoothly, thus stopper rod 4 is pulled out from the tap hole of teapot-type ladle.
Finally entered pouring area poured into a mould workpiece by driving ladle 3 of slinging.The form of toppling over of ladle 3 adopts electric rocking pack arrangement, remote controller operation.Namely motor, speed reduction unit and remote-receiver are set on ladle 3.Power supply is following from travelling crane hook, power acquisition aviation quick connector form.In addition the spout of a teapot shape tap hole in order to overcome ladle 3 causes ladle 3 centre-of gravity shift, and ladle 3 gudgeon position needs slightly to offset toward side, tap hole opposite.
