Abstract
The utility model relates to a quick constant diameter water gate replacing device for small square billet continuous casting tundishes, which comprises a fixed bracket and a tundish, a base brick and a constant diameter water gate, wherein the base brick is arranged in the tundish and the constant diameter water gate is arranged in the middle part of the base brick. The utility model also comprises more than two sliding slots, solid sliding boards or water gate sliding boards, and a hydraulic cylinder, wherein the sliding slots are connected with the fixed bracket and arranged on the bottom of the tundish, the solid sliding boards or water gate sliding boards are arranged in the sliding slots and the hydraulic cylinder is connected with the solid sliding boards or the water gate sliding boards. By adopting the utility model, the lining material of the tundish can be reduced and the rapid pouring stop can be realized. The constant diameter water gate with different hole diameters is replaced in the process of new pouring start and pouring.
Description
The utility model relates to the continuous casting of iron and steel device, particularly a kind of quick replacement device of continuous small-billet casting tundish metering nozzle.
Although it is only and high temperature resistant that existing continuous small-billet casting tundish metering nozzle has adopted chemically-resistant to invade, the zirconium material that the molten steel of anti-the high speed washes away is strongly made, but in actual use, because a variety of causes is not saturating such as the baking in the use, it is too frequent to burn the oxygen operation, dress mouth of a river misoperation, inappropriate technology in the manufacturing process, raw material instability etc., still have some mouths of a river that hole enlargement and cracking in use take place, therefore, some steel mill is forced to select for use some stopper that is not suitable for continuous small-billet casting cast structures and mode to replace the metering nozzle cast, so must increase production cost, if and change tundish, a large amount of wastes of cylinder-packing and associated materials in the middle of then causing.
The purpose of this utility model provides a kind of quick replacement device of continuous small-billet casting tundish metering nozzle, and it can reduce the tundish lining material, realize stopping fast to water, open again water and casting process in change the metering nozzle in different apertures.
The technical solution of the utility model is as follows: a kind of quick replacement device of continuous small-billet casting tundish metering nozzle comprises fixed support, tundish, the brick cup that is provided with in tundish, and the metering nozzle that is provided with in the middle of brick cup; It also comprises the chute that is connected with fixed support more than two, be positioned at the tundish bottom, solid slide plate of installing or mouth of a river slide plate, and the hydraulic cylinder that is connected with solid slide plate or mouth of a river slide plate in chute; Metering nozzle is divided into filling pipe end and the mouth of a river, bottom slide plate or solid slide plate, and filling pipe end is arranged in the brick cup, and mouth of a river slide plate and solid slide plate are pushed in pouring position or holding fix alternately by hydraulic cylinder, has promptly changed metering nozzle fast.
Adopt quick replacement device described in the utility model to have following advantage:
1. reduce tundish lining material, baking bag energy medium, reduced the consumption of building the bag manpower.
2. reduced and to have burnt the product quality that the oxygen operation caused and worsen, and the bleedout that produces therefrom etc. influence the accident that continuous casting even waters.
3. reduce the surplus steel of tundish, improved the continuous casting recovery rate.
4. can realize stopping fast to water, open again water and casting process in change the mouth of a river, location in different apertures, with the liquid steel temperature that adapts to the phase before and after the cast, mobile and the optimum Match of pulling rate and the coupling of supplying with the stokehold molten steel.
5. stablized the continuous casting rhythm of production, and even the rhythm of production of whole steelmaking system.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a kind of quick replacement device structural representation of continuous small-billet casting tundish metering nozzle.
Fig. 2 is the stereogram of the chute in the above-mentioned quick replacement device, solid slide plate and mouth of a river slide plate.
Referring to Fig. 1 and Fig. 2, a kind of quick replacement device of going billet continuous casting tundish metering nozzle comprises fixed support 1, tundish 2, the brick cup 3 that is provided with in tundish 2, and the metering nozzle 4 that is provided with in the middle of brick cup 3.
It also is equipped with two 1 that be connected with fixed support, as to be positioned at tundish 2 bottoms chutes 5, and solid slide plate 6 or mouth of a river slide plate 7 are installed in chute 5.Be connected and installed hydraulic cylinder 8 respectively with solid slide plate 6 or mouth of a river slide plate 7.
Metering nozzle 4 is divided into filling pipe end and the mouth of a river, bottom slide plate 7 or solid slide plate 6, and filling pipe end is arranged in the brick cup 3.Mouth of a river slide plate 7 and solid slide plate 6 are pushed in pouring position or holding fix alternately by hydraulic cylinder 8, have promptly changed metering nozzle 4 fast.
When ladle injected molten steel in tundish 2, solid slide plate 6 was in pouring position, and the mouth of a river slide plate 7 of respective aperture is in holding fix.
When beginning to pour into a mould, mouth of a river slide plate 7 moves forward to pouring position, and solid slide plate 6 is pushed out pouring position, is placed in holding fix again with stylish mouth of a river slide plate 7 or solid slide plate 6.
When the slide plate 7 of cast need more renew after a period of time the mouth of a river, then new mouth of a river slide plate 7 is moved to pouring position.When stopping watering, then solid slide plate 6 is moved to pouring position.
Because by means of hydraulic cylinder 8 operation, so the replacing process can finish in part second, the steel miscarriage given birth to depart from, and its operation is very simple.
