Description
Technical Field
The utility model relates to a ferrous metallurgy field, in particular to low-cost stifled middle package that stops steel stream stifled device that flows.
Background
In the casting process of a continuous casting machine of a steel plant, because of a series of reasons such as difficult molten steel connection and the like, the molten steel flow needs to be stopped, under the conditions of high molten steel temperature and diameter-expanded water gaps, the molten steel is difficult to stop, so that a large amount of blocked cones are wasted, a large amount of molten steel flows into a steel overflow basin seriously, and even more, the whole group of steel is forced to stop casting, the molten steel flow needs to be stopped when the casting time of a tundish reaches a specified time, namely the tundish stops casting, and the steel flow needs to be stopped, the traditional flow stopping method adopts small blocking cones to tightly block the inner diameter of the lower water gap, so that the purpose of stopping the molten steel flow is achieved, according to the current yield, the casting needs to be stopped for more than 2 groups or 2 groups every three shifts every day, the small blocking cones are used for about 15 times every day averagely, each small blocking cone costs 9 yuan, the.
SUMMERY OF THE UTILITY MODEL
In view of the above, to achieve the purpose of cost reduction and efficiency improvement, the present invention improves the conventional flow blocking method, and aims to provide a simple and effective flow blocking device with low cost for blocking and stopping steel flow.
The technical scheme is as follows:
the utility model provides a middle package device that blocks up, includes the middle package, and quick change mechanism locates the middle package below, and the slip is equipped with quick change mouth of a river and blind plate on the quick change mechanism, and the through-hole of quick change mouth of a river corresponds with the downthehole of mouth of a river that the middle package steel flows down, blocks up when stopping the steel and flows, slides the blind plate to change mouth of a river preparation position, puts hydraulic oil pole on quick change mechanism, promotes this blind plate through hydraulic oil pole and slides to the casting position along the slide rail, when the blind plate with the downthehole alignment of mouth of a river is flowed down to the middle package steel, and the steel flows is stopped.
Preferably, the blind plate is a waste quick-change drainage port filled with an asbestos plate.
Preferably, the quick change mechanism is equipped with the slide rail including locating the baffle of middle package below both sides on the baffle, quick change mouth of a river and blind plate both sides along the slide rail, and the middle package bottom slides is pasted at the top.
Preferably, a through hole is formed in the waste quick-change drain port, and the asbestos plate is filled in the through hole.
The utility model has the advantages that:
(1) the utility model discloses a stifled success rate of flowing is higher, and significantly reduces to flow into excessive steel basin molten steel 3 tons/month because of stifled failure, practices thrift small stifled awl 15 on average every day.
(2) About 2 groups of pouring forced to be stopped due to flow blockage failure every year is saved, and about 100 tons of molten steel is recycled.
(3) The situation that molten steel splashes due to the fact that the molten steel flow is blocked can be avoided, and scalding of an operator is avoided.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be further described below with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of the tundish blockage device of the present invention. As shown in fig. 1-3, the tundish blockage device comprises a tundish 1, a quick-change mechanism 3 is arranged below the tundish 1, a quick-change nozzle 4 and a blind plate are slidably arranged on the quick-change mechanism 3, a through hole of the quick-change nozzle 4 corresponds to a hole of a steel lower nozzle of the tundish 1, when a steel flow is blocked, the blind plate slides to a nozzle replacement preparation position 7, a hydraulic oil rod is placed on the quick-change mechanism 3, the blind plate is pushed by the hydraulic oil rod to slide to a casting position 8 along a slide rail, and when the blind plate is aligned with the hole of the steel lower nozzle of the tundish 1, the steel flow is blocked.
The blind plate is a waste quick-change lower nozzle 5 filled with an asbestos plate 6.
The quick-change mechanism 3 comprises baffles arranged on two sides of the lower portion of the tundish 1, slide rails are arranged on the baffles, the quick-change water gap 4 and two sides of the blind plate slide along the slide rails, and the top of the quick-change water gap is attached to the bottom of the tundish 1 and slides.
A through hole is arranged in the waste quick-change drain port 5, and the asbestos plate 6 is filled in the through hole.
The utility model discloses stifled success rate of class device is high, reduces the overflow molten steel, practices thrift little stifled awl, and avoids stifled steel stream that stops to lead to the molten steel to splash.
The utility model discloses not be limited to the specific details among the above-mentioned embodiment the utility model discloses a within the technical idea scope, can be right the technical scheme of the utility model carry out multiple simple variant, these simple variants all belong to the utility model discloses a protection scope.
