Abstract
The utility model relates to a steel-making continuous-casting tundish with a flow guiding device, comprising a tundish body; a permanent layer and a working layer made of refractories; and a slag dam which is arranged in the tundish and divides the tundish into an impacting area and a casting area. The utility model is characterized in that a downward casting flow guiding passage is provided between the impacting area and the casting area. The downward casting flow guiding passage is an arc-shaped or L-shaped passage made of refractories; the inlet of the passage is arranged in the impacting area, and the outlet in the casting area. The utility model has the advantages that adoption of the structure prevents steel slag from entering the casting area, thereby avoiding secondary pollution to the molten steel, completely eliminating the influence on the cast slab quality by level fluctuation or form later casting period and effectively improving the cast slab quality.
Description
Technical field
The utility model belongs to the continuous casting of metal field, particularly relates to the continuous casting tundish of the band guiding device that a kind of pour steel uses.
Background technology
At present, steel mill has been taked multiple measure for improving steel quality, as slag blocking wall (weir) is set on tundish, tundish is divided into the impact zone and the pouring area of molten steel, and on slag blocking wall, having pod apertures, the effect of its pod apertures is to allow molten steel pass through to stop slag to pass through.But the slag blocking wall of this structure and pod apertures also exist certain problem, as connecting the process of watering or cast later stage, are mingled with because liquid fluctuating or liquid level are crossed low causing, and enter pouring area, and the pollution molten steel influences slab quality.
Summary of the invention
The purpose of this utility model provide a kind of can change steel flow to, prevent the molten steel secondary pollution, reduce molten steel and be mingled with, improve the continuous casting tundish of the band guiding device of billet quality.
Continuous casting tundish according to band guiding device of the present utility model, comprise the tundish body, the permanent layer and the working lining that constitute by refractory material, be arranged on the slag blocking wall that in the tundish tundish is divided into impact zone and pouring area, it is characterized in that between described impact zone and pouring area, being provided with " bottom pouring type " flow-guiding channel.
According to the continuous casting tundish of band guiding device of the present utility model, described " bottom pouring type " flow-guiding channel is to make " arc " type or " L " type passage by refractory material, and the import of this passage is located at impact zone, and outlet is located at pouring area.
Can flow into pouring area smoothly from " bottom pouring type " flow-guiding channel in order to satisfy the molten steel that cast is trapped in the impact zone latter stage, when the utility model is made bakie working lining the working lining of described impact zone be made working lining a little more than pouring area.
Advantage of the present utility model is: owing to adopted said structure, make slag can not enter pouring area, prevented the molten steel secondary pollution, thoroughly solved because liquid fluctuating or cast later stage influence the problem of slab quality, improved slab quality effectively.
Description of drawings
Fig. 1 adopts the partial cutaway diagrammatic sketch of " arc " type " bottom pouring type " flow-guiding channel for the utility model tundish.
Fig. 2 be the impact zone of the utility model tundish a little more than pouring area, adopt the partial cutaway diagrammatic sketch of " L " type " bottom pouring type " flow-guiding channel.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to accompanying drawing 1, the continuous casting tundish of the utility model band guiding device, comprise tundish body 1, the permanent layer 3 and the working lining 2 that constitute by refractory material, be arranged on the slag blocking wall 4 that in the tundish tundish is divided into impact zone and pouring area, the left side of accompanying drawing is an impact zone, and the right side is a pouring area, it is characterized in that being provided with between described impact zone and pouring area " bottom pouring type " flow-guiding channel 5.Described " bottom pouring type " flow-guiding channel 5 can be made " arc " type or " L " type with refractory material, the import of this passage 5 is located at impact zone, outlet is located at pouring area, owing to adopted " bottom pouring type " flow-guiding channel 5, downward angle of formation naturally between the import of flow-guiding channel and outlet, can produce siphonage, molten steel is delivered to pouring area from impact zone reposefully.
The outlet of the utility model " bottom pouring type " flow-guiding channel 5 can be designed to different angles and shape according to flow field, temperature field, the molten steel time of staying of tundish.
Can flow into pouring areas smoothly from " bottom pouring type " flow-guiding channel 5 in order to satisfy the molten steel that cast is trapped in the impact zone latter stage, the utility model makes the impact zone working lining of tundish a little more than the pouring area working lining, at this moment generally adopt " L " type " bottom pouring type " flow-guiding channel, referring to accompanying drawing 2.This flow-guiding channel is not only made simply, and can satisfy to pour into a mould fully and be trapped in the interior molten steel of impact zone latter stage and flow out smoothly, thoroughly solved because liquid fluctuating or cast later stage influence the problem of slab quality, improved slab quality, can also make part residue molten steel become qualified base, improve the molten steel recovery rate.
The utility model is suitable for single current or multithread tundish, when being applied in the multithread tundish, can establish a plurality of " bottom pouring type " flow-guiding channel 5 between the impact zone of tundish and pouring area.This flow-guiding channel 5 can also adopt refractory material to make difformity, aperture, size according to the shape of tundish, the diameter at the mouth of a river, makes flow field, temperature field, the molten steel time of staying of tundish more reasonable.
Claims (3)
1, a kind of continuous casting tundish with guiding device, comprise the tundish body, the permanent layer and the working lining that constitute by refractory material, be arranged on the slag blocking wall that in the tundish tundish is divided into impact zone and pouring area, it is characterized in that between described impact zone and pouring area, being provided with " bottom pouring type " flow-guiding channel.
2, the continuous casting tundish of band guiding device according to claim 1 is characterized in that described " bottom pouring type " flow-guiding channel is to make " arc " type or " L " type passage by refractory material, and the import of this passage is located at impact zone, and outlet is located at pouring area.
