Abstract
The utility model relates to an opening and closing device for a ladle nozzle mainly used for refining and pouring. The opening and closing device solves the main problems of capabilities of carrying out refining with multiple times of opening and closing, and performing single-ladle multi-box pouring. The opening and closing device is provided with a slide nozzle opening and closing device arranged at the bottom of a ladle, and a stopper rod device, wherein the stopper rod device includes a lifting mechanism fixed to the side wall of the ladle, a folding arm and a stopper rod mounted in the ladle, one end of the folding arm is connected with the lifting mechanism, and the stopper rod is mounted at the other end of the folding arm.
Description
Technical field
The utility model relates to field of metallurgy, particularly a kind of headstock gear that is mainly used in the ladle nozzle of refining and casting.
Background technology
The headstock gear of existing ladle nozzle mainly contains slide gate nozzle headstock gear and stopper device.The slide gate nozzle headstock gear is to utilize the slide plate that is positioned at below, the mouth of a river to move to open and close the mouth of a river, and the shortcoming of this headstock gear is to open and close number of times seldom, and ladle can only open and close 4-6 time at most after containing molten steel.The cold charge stopper device is just stopper and opener to be fixed on the ladle before ladle is contained molten steel, and then contain molten steel and implement cast, obvious this headstock gear can't be used for need be to the occasion of molten steel in the ladle or liquid metal enforcement refining, and can bring many adverse influences to process operations, the efficient of its operation is lower, and labour intensity is bigger.
Summary of the invention
Problem to be solved in the utility model provides a kind of headstock gear of implementing refining and opening and closing ladle nozzle often.
The technical scheme that the utility model addresses the above problem is: the headstock gear of the ladle nozzle that is provided has the slide gate nozzle headstock gear that is located at ladle bottom, special feature of the present utility model is: also be provided with a stopper device, this stopper device comprises elevating mechanism, a bent over arms that is fixed on the ladle sidewall and is installed in the interior stopper of ladle, wherein an end of bent over arms is connected with elevating mechanism, and stopper is contained in the other end of bent over arms.
For the ease of dismounting, be connected by bearing pin between an end of bent over arms and the elevating mechanism.
The course of work of the present utility model is: unload stopper earlier before containing molten steel, contain molten steel again, the ladle that fills molten steel is moved on to the refining furnace refining, refining finishes and refills stopper enforcement cast.Open the slide gate nozzle headstock gear when pouring into a mould first, mention stopper, molten steel flows out from the mouth of a river, and cast finishes and handles stopper decline, and the mouth of a river is blocked, and ladle is moved on to the next position again and implements cast for the second time, and the rest may be inferred.Slide gate nozzle headstock gear of the present utility model is just opened when pouring into a mould for the first time, no longer closes later on, and the follow-up complete utilization stopper that pours opens and closes ladle nozzle.
The utility model combines slide gate nozzle headstock gear and stopper device, when the slide gate nozzle headstock gear mainly is used in refining to the shutoff at the mouth of a river, the keying of ladle nozzle is then mainly finished by stopper during cast, thereby can satisfy in the production requirement to product material and various product structures, make that particularly repeatedly cast becomes very convenient, ladle is able to turn on or off nearly more than 30 times after containing molten steel.
Description of drawings
Fig. 1 is a structure diagram of the present utility model.
The specific embodiment
As shown in Figure 1: the bottom of ladle 1 is provided with slide gate nozzle headstock gear 2, the ladle sidewall is provided with elevating mechanism 3, a Γ shape bent over arms 4 and is installed in stopper 5 in the ladle, wherein be connected by bearing pin 41 between the lower end of bent over arms 4 and the elevating mechanism 3, the other end of bent over arms 4 is the forearms 42 with U-shaped opening, in the forearm 42 suit bent over arms transverse arms 43 (so that adjust the distance of 41 of stopper and bearing pins, guarantee stopper aligning ladle nozzle center), stopper 5 upper ends are contained in this U-shaped opening, and fixing with nut 44.Elevating mechanism 3 is leverages, and its control stick 31 is hinged on the ladle sidewall, can drive 4 liftings of Γ shape bent over arms by action bars.
At first stopper to be contained in the ladle in advance before the ladle working and debug, for the hot charging stopper is prepared, its process is: it is other that ladle moves on to hanging apparatus 6, stopper 5 is put in the ladle 1, the stopper head is pressed on the sliding sprue tile for smelting 11, behind the upright straight stopper it is rotated, grinds, guarantee that stopper head and nozzle brick can tight connectings.The main transverse arm 61 of outside hanging apparatus 6 blocks Γ shape bent over arms 4 by bearing pin 62, rotate main transverse arm 61, bent over arms 4 is moved to the ladle top, hoist cylinder 63 decline bent over arms by hanging apparatus 6, the bearing pin 41 of bent over arms 4 lower ends is inserted in the hole of elevating mechanism 3 upper end adpting flanges, the upper flange surface of elevating mechanism 41 is closely contacted with the lower flange face of Γ type bent over arms 4 lower ends, then two drifts are squeezed in the pin shaft hole of bent over arms lower end, guaranteed that the upper flange of elevating mechanism and the lower flange of bent over arms are connected firmly; Packed in the U-shaped opening of bent over arms front end in stopper 5 upper ends, and make stopper be in plumbness, the stopper head is over against nozzle brick, move the control stick 31 of elevating mechanism, drive bent over arms 4 rising certain altitudes, two cover nuts with the stopper upper end are fixed on the stopper upper end in the U-shaped opening of bent over arms forearm 42 then; Decontrol the control stick of elevating mechanism, the main transverse arm 61 of hanging apparatus is separated with bent over arms 4, so far, the debugging of hot charging stopper cold conditions finishes.
During work, bent over arms 4 is separated with elevating mechanism 3, shift out ladle, move to the refining of refining station behind the ladle splendid attire molten steel together with stopper, refining finishes and bent over arms 4 and stopper 5 is installed on the ladle again, move to the cast station, open slide gate nozzle, allow drainage sand 7 flow down by the control stick 21 of slide gate nozzle headstock gear 2, move the control stick 31 of elevating mechanism 3, mention stopper 5, allow molten steel flow out, implement cast.
