Abstract
The present invention relates to a kind of method for suppressing ladle to be vortexed slag, comprises the following steps：1) when ladle is poured into a mould, molten steel is vortexed when flowing to collector nozzle clockwise in ladle, and steel stream is subject to the obstruction backwash power of ladle bottom protrusion structure to reduce, reduced velocity flow；2) latter stage is poured into a mould in ladle, when ladle is poured into 10%-13%, close steel ladle slide board 2-3.5 second, then open slide plate.Advantage is：By building bulge-structure by laying bricks or stones in molten steel pot bottom and coordinating cast latter stage to control sliding-plate switch, reduce the impact of ladle internal vortex, the waste and the impact to ladle Cleanliness of Molten Steel of the iron and steel stock that the too early slag of suppression ladle is caused, it is suppressed that the generation of the surplus steel wasting phenomenon of ladle.
Description
Technical field
The present invention relates to a kind of method for suppressing ladle to be vortexed slag.
Background technology
When ladle is poured, vortex inside ladle, is also easy to produce, in cast latter stage vortex phenomenon acutely, top slag is involved in vortex,
The too early slag of ladle is caused, larger is polluted to ladle Cleanliness of Molten Steel, if now close slide plate to stop pouring, remained in ladle
Steel is more, and iron and steel stock wastes larger.
The content of the invention
To overcome the deficiencies in the prior art, it is an object of the invention to provide a kind of method for suppressing ladle to be vortexed slag, passes through
Change ladle polycrystalline substance, and ladle sliding-plate switch to slow down ladle internal vortex phenomenon, suppress ladle to shift to an earlier date
The ladle Cleanliness of Molten Steel that slag is caused declines, and the surplus steel wasting phenomenon of ladle.
For achieving the above object, the present invention is achieved through the following technical solutions：
A kind of method for suppressing ladle to be vortexed slag, comprises the following steps：
1) when ladle is poured into a mould, molten steel is vortexed when flowing to collector nozzle clockwise in ladle, and steel stream is subject to ladle bottom
The obstruction backwash power of portion's bulge-structure reduces, reduced velocity flow；
2) latter stage is poured into a mould in ladle, when ladle is poured into 10%-13%, close steel ladle slide board 2-3.5 second, then
Open slide plate.
Described bulge-structure is arranged on molten steel pot bottom, bulge-structure around the molten steel pot bottom collector nozzle with air brick it
Between, it is made up of the brick of building by laying bricks or stones of perpendicular block.
Described bulge-structure, builds brick by laying bricks or stones by two rows and is formed, and often arranges three pieces of each perpendicular block and builds brick by laying bricks or stones.
Compared with prior art, the invention has the beneficial effects as follows：
By bulge-structure being built by laying bricks or stones in molten steel pot bottom and coordinating cast latter stage to control sliding-plate switch, reduce ladle internal vortex
Impact, suppress the waste and the impact to ladle Cleanliness of Molten Steel of the iron and steel stock that the too early slag of ladle causes, suppress
The generation of the surplus steel wasting phenomenon of ladle.
Description of the drawings
Fig. 1 is ladle structural representation.
In figure：1- ladle 2- build brick 3- collector nozzles by laying bricks or stones.
Specific embodiment
The present invention is described in detail with reference to Figure of description, it should be noted that the enforcement of the present invention be not limited to
Under embodiment.
See Fig. 1, by taking 100 tons of ladles as an example：The method for suppressing ladle to be vortexed slag, comprises the following steps：
1) 1 bottom of ladle between collector nozzle 3 and air brick by the way of perpendicular block is built two rows by laying bricks or stones and builds brick 2 by laying bricks or stones, often arranges three
Block, forms bulge-structure, and remaining is built by laying bricks or stones brick and is still built by laying bricks or stones by the way of sleeping block.When ladle 1 is poured into a mould, molten steel vortex
When flowing to collector nozzle 3 clockwise in the ladle 1, steel stream is subject to the obstruction backwash power of 1 bottom protrusion structure of ladle to subtract
It is little, reduced velocity flow；As the top of ladle 1 slag density is lighter, in the case where molten steel flow speed slows down, slag phenomenon is inhibited,
Slow down top slag to be involved in.
2) the violent row of 1 inside molten steel vortex phenomenon of ladle is involved in stream by vortex power and enters relatively early in tundish into whirlpool, and one
As pour into a mould in big tank and also remain 10～13 ton hours and be just involved in slag phenomenon, and now also remain a part of steel inside ladle 1
Water, concrete operations are：Pour to 13 ton hours (10-13 tons, 13 tons of best results) in big tank, close steel ladle slide board 2-3.5
Second, preferably 3 seconds, then open slide plate.The vortex produced in making ladle 1 is subject to reverse impact, vortex phenomenon to subtract
Slowly, push up slag density lighter, float after vortex is suppressed, 1 bottom of ladle is molten steel, is poured after slide plate is pulled open again
Note is pure molten steel, it is to avoid because being vortexed the slag that slag is caused too early, and closes slide plate immediately and stop pouring caused steel
Water pot 1 remains steel wasting phenomenon.
By building bulge-structure by laying bricks or stones in molten steel pot bottom, the part of ladle bottom protrusion produces raw breaking to molten steel vortex to the present invention
It is bad to act on；Meanwhile, coordinate cast latter stage control sliding-plate switch, reduce the impact of ladle internal vortex, suppress ladle mistake
The waste of the iron and steel stock that early slag is caused and the impact to ladle Cleanliness of Molten Steel, it is suppressed that the surplus steel wasting phenomenon of ladle
Generation.
