Abstract
The utility model belongs to an improved slag weir used for the tundish of the steelmaking, which is mainly characterized in that the slag weir take a barrel-type shape, a plurality of guiding holes are arranged at the weir body, a swash plate is arranged at one end of the weir body. The utility model has the advantages of rational structure, steady steel stream and safe operation, suitable for the improvement of the continuous casting tundish of the steelmaking, increasing the quality of the billet.
Description
The utility model relates to a kind of slag weir that is used for the steel-making continuous casting tundish.
Steel mill has been taked multiple measure for further improving steel quality, and using slag weir on tundish promptly is wherein a kind of method of promoting steel quality.At present, steel mill generally adopts plate slag weir (as shown in Figure 1), has pod apertures on the weir plate face, and slag weir stands upright in the tundish, and tundish is separated into two parts.The effect of pod apertures is to allow molten steel pass through to stop slag to pass through.Along with the extensive popularization of continuous casting, steel mill has changed the shape of tundish, causes plate slag weir can not adapt to altered tundish and tundish can not form good linking, occurs easily leaking the slag phenomenon, has influenced steel quality.So, develop a kind of can be imperative with the slag weir that novel tundish matches.
The purpose of this utility model provides a kind of tundish that can adapt to better to improve the slag weir of steel quality.
Accompanying drawing 1 is existing plate slag weir structural representation.
Accompanying drawing 2 is the utility model slag weir structural representations.
The utility model is like this design: slag weir weir body is cylinder-shape, on the body of tubular weir Have some pod apertures, tubular weir body one end arranges a shock plate. During slag weir is installed in Between when wrapping, an end of shock plate is fixedly mounted on the bottom of tundish on the body of weir.
The slag weir shock plate can directly be fixed on the weir body, is integrated with the weir body; Perhaps also can separate, in use the weir body be cooperated with the shock plate installation with the weir body.
The utility model slag weir is rational in infrastructure, and steel stream is stable, and handling safety has adapted to the improvement of steel-making continuous casting tundish, has improved billet quality.
As shown in Figure 2, the utility model slag weir 1 can be designed to cylinder-shape, and its cross section can be circular, perhaps also can be rectangle.Have several pod apertures 2 on the body of weir, be provided with a shock plate 3 at weir body one end.
Shock plate 3 can link into an integrated entity with the weir body, as shown in Figure 2, also can separate with the weir body.Only when using slag weir, again shock plate and weir body are assembled up, be installed in the tundish.
Claims (3)
1, a kind of slag weir that is used to make steel tundish is characterized in that described slag weir cylinder-shape, on the body of tubular weir pod apertures is arranged, and body one end in weir is provided with a shock plate.
2, steel-making tundish slag weir according to claim 1 is characterized in that shock plate is fixed on weir body one end, and fuses with the weir body.
3, steel-making tundish slag weir according to claim 1 is characterized in that shock plate separates with the weir body, refills to be fitted on the body of weir when installing and using slag weir.
