Abstract
The utility model discloses a kind of Y type mouth of a river of uniform temperature, the liquid mixing of two Baogangs can be injected tundish.This mouth of a river comprises: molten steel entrance A, molten steel entrance B, upper slide, lower skateboard, lower nozzle brick and long peg gate, described molten steel entrance A and molten steel entrance B and long peg gate form symmetrical y-type structure, be respectively equipped with upper slide and lower skateboard at the middle part of molten steel entrance A and molten steel entrance B, upper slide is connected long peg gate with lower skateboard by lower nozzle brick.The utility model makes the molten steel of two ladles enter from two ends, mixes, enter tundish in long peg gate, reduces the impulsive force of molten steel, can carry out the adjustment of temperature simultaneously, provides convenience for producing.This gate structure is simple, is easy to operation.Molten steel can be mixed well, effectively reduce tundish temperature fluctuation range.
Description
Technical field
The utility model relates to continuous casting production pouring device, particularly a kind of Y type mouth of a river of uniform temperature.
Background technology
Tundish metallurgy is the outer metallurgical technology of a special stove, is from the melting of steel and is refined to key one ring made solid-state continuous casting billet production procedure.At the initial stage of continuous casting steel machine technical development, tundish just uses as the storage of molten steel and distributor.Along with the development of continuous casting technology, quality of molten steel to the significance of continuous casting process gradually by people are familiar with.In continuous casting process, the temperature fluctuation of molten steel can cause serious impact to the quality of strand.Therefore, the impact that the structure of tundish fluctuates on molten steel temperature, receives increasing concern.By test, steel mill of Japan confirms that H type tundish effectively can improve the flow behavior of molten steel, eliminate short circuit, improve the distribution in temperature field.H type tundish and normal T-shaped tundish different are to have had more one and are specifically designed to and accept and mix the bag of molten steel, in casting process, the different molten steel of two bag temperature can be made to mix, reduce the scope of temperature fluctuation.But H type tundish body structure is complicated, molten steel wherein time, physical thermal loss is comparatively large, and cleanliness factor wherein also has a significant impact the pure of molten steel simultaneously.
Patent publication No.: CN103506612A, discloses a kind of tundish for molten steel casting.This tundish comprises bottom and indentured two parts, wherein indenturedly being arranged on above described bottom and being connected with its sealing, bottom and indenturedly comprise again permanent layer and working lining, permanent layer both sides are equipped with high-temperature water mud layer, bottom is also provided with shock plate and the mouth of a river, is also provided with gudgeon on indentured.But this tundish uses as just common tundish, the mixing for molten steel does not play a role.
Patent publication No.: CN102441664A, discloses a kind of method for ladle molding casting in vacuum pouring process.This method provide a kind of mouth of a river, be connected on collector nozzle of ladle, secondary oxidation and splashing is there is when molten steel can be avoided to inject tundish, solve due to secondary oxidation and splash that the molten steel quality that causes reduces, pouring basket liquid level is unstable, the problem of impact cast and ingot quality, and install convenient.But it only as a kind of single device, only plays a protective role, and does not play mixing molten steel, reduce the effect of molten steel impact power.
Utility model content
The novel Y type mouth of a river providing a kind of uniform temperature of the utility model, can inject tundish by the liquid mixing of two Baogangs.
The Y type mouth of a river of a kind of uniform temperature that the utility model provides comprises: molten steel entrance A, molten steel entrance B, upper slide, lower skateboard, lower nozzle brick and long peg gate, described molten steel entrance A and molten steel entrance B and long peg gate form symmetrical y-type structure, be respectively equipped with upper slide and lower skateboard at the middle part of molten steel entrance A and molten steel entrance B, upper slide is connected long peg gate with lower skateboard by lower nozzle brick.
The utility model is compared with existing same device, and its beneficial effect is embodied in:
The molten steel of two ladles enters from two ends, mixes, enter tundish in long peg gate, reduces the impulsive force of molten steel, can carry out the adjustment of temperature simultaneously, provides convenience for producing.This gate structure is simple, is easy to operation.Molten steel can be mixed well, effectively reduce tundish temperature fluctuation range.
Accompanying drawing explanation
Fig. 1 is a kind of Y type gate structure schematic diagram of uniform temperature.
Specific embodiments
Below in conjunction with accompanying drawing embodiment, the utility model is further described.
As shown in Figure 1, a kind of Y type mouth of a river of uniform temperature, this mouth of a river is made up of molten steel entrance A3, molten steel entrance B4, upper slide 5, lower skateboard 6, lower nozzle brick 7 and long peg gate 8, described molten steel entrance A3 and molten steel entrance B4 and long peg gate 8 form symmetrical y-type structure, be respectively equipped with upper slide 5 and lower skateboard 6 at the middle part of molten steel entrance A3 and molten steel entrance B4, upper slide 5 is connected long peg gate 8 with lower skateboard 6 by lower nozzle brick 7.Ladle A1 is put in above molten steel entrance A3 through there being traveling crane, molten steel entrance A3 diameter is a bit larger tham ladle A1 delivery port diameter, molten steel injects through molten steel entrance A3, open upper slide 5 and lower skateboard 6, molten steel is injected in tundish through long peg gate 8, and in like manner the molten steel of ladle B2 is injected in molten steel entrance B4.The present embodiment ladle delivery port flow is 2.5t/min, and mouth of a river diameter is 80mm, ladleful 100t.Molten steel entrance A3 and molten steel entrance B4 flow are 2.5t/min, and diameter is 80mm.Long peg gate 8 flow is 5t/min, and diameter is 100mm.
