Abstract
The utility model relates to a multifunctional integral current stabilizer which is installed in an impact zone on the bottom of a tundish and integrates a slag baffling wall, a current stabilizer, a leakproof plate and a guard board. The device is a hollow opened six-prismoid integral structure which is composed of six lateral surfaces and a bottom surface, the opened portion is big, and the bottom is small. A plurality of diverting holes are arranged on the lateral surfaces which are not contacted with a tundish working lining and the leakproof plate is installed on the bottom surface of the device. The multifunctional integral current stabilizer has the advantages that the device relates to the multifunctional integral current stabilizer which integrates the slag baffling wall, the current stabilizer, the leakproof plate and the guard board, are designed and developed on the basis of a traditional slag baffling wall structure, and has the advantages of simple construction, strong erosion resistance and brushing resistance ability, and the like. The delaying time of steel water in the tundish can be prolonged, which is beneficial for floating inclusion, increasing the casting blank quality, and avoiding the water gap clogging.
Description
Technical field
The utility model relates to a kind of tundish bottom impact zone that is installed in, and integrates the multifunctional integral flow straightener of slag blocking wall, flow straightener, Antileaking plate and backplate.
Background technology
Along with the development of continuous casting technology with to improving constantly that slab quality requires, effect as last refining vessel tundish in the steelmaking process is very important, it the more important thing is the effect that promotes inclusion floating, eliminating and cleaning molten steel of playing except stablizing beam, realizing the sequence casting.The flow control device that appropriate format is set in tundish can make that field trash fully floats in the tundish, and molten steel has rational flow pattern and enough time of staying in tundish.
Before the 1950's, conticaster mostly is single current or double fluid, and the continuous casting furnace number is lower, does not establish any structure in the tundish, and it only plays the effect that reduces molten steel pressure, even liquid steel temperature and molten steel composition.The 1950's, people such as B.C. Lu Jiesi adopt the method for hydraulic analogy test to study, and think that the tundish slag blocking wall has obvious effects for cleaning molten steel.The seventies in 20th century, the metallargist is provided with weir, dam structure in tundish.Austrian Voest steel mill is when the oxide inclusions of research carbon aluminium-killed steel, done the contrast test that has or not slag blocking wall, the result shows, when other condition is identical, have and be mingled with content in the strand of slag blocking wall and reduce 45%, but there are following two shortcomings: the one, the part slag can flow into the workspace, both sides with beam because of having little time come-up, makes strand contain big steel slag; The 2nd, not strong to the flow regime control ability of molten steel in the workspace, molten steel stream only advances with the simple type of flow, makes uneven components in the molten steel.The eighties in 20th century, metallargist Jiang Yan, dam structure are merged into the slag blocking wall that tap hole is set.Molten steel flows into pouring area through tap hole, and the slag retaining in the long nozzle district, by regulating the quantity and the blowing angle of tap hole, can be obtained than weir, the better molten steel flow regime of dam structure, makes molten steel flow steadily, mix more even in flow region.When the top of the slag drop to the highest tap hole when following slag will enter the workspace of both sides by tap hole, be unfavorable for the cleaning of molten steel and the removal that is mingled with.Simultaneously, the cylinder-packing in beam district also can be subjected to washing away of molten steel and deteriorate.
In the later stage nineties 20th century, many researchers have developed a kind of new removal field trash technology---pottery molten steel filter again, remove that middle-size and small-size to be mingled with effect obvious.But this technology is not widely used, and its reason is: (1) molten steel temperature height, and the duration of pouring is long, washing away and corroding seriously, its life-span weak point filter; (2) specific area of filter is limited, and eyelet is easily blocked, is difficult to satisfy the requirement of molten steel continuous filtration; (3) ceramic filter manufacturing process complexity, production cost is higher.
Summary of the invention
At the situation of prior art, the purpose of this utility model provides a kind of tundish multifunctional integral flow straightener, can prolong the time of staying of molten steel in bag, helps inclusion floating, improves slab quality, has avoided nozzle blocking.
The utility model tundish is described below with the technology contents of multifunctional integral flow straightener:
Tundish multifunctional integral flow straightener is characterized in that: this device is that its oral area is big, the bottom is little by six sides and the hollow uncovered six terrace with edge overall structures that the bottom surface constitutes.
With on the side that the tundish working lining contacts be not provided with several tap holes at it; The device bottom surface is equipped with Antileaking plate.
The advantage of this device is: this device is on the basis of traditional slag blocking wall structure, designed and developed and integrated slag blocking wall, flow straightener, Antileaking plate and backplate multifunctional integral flow straightener, it is simple to have construction, advantage such as anti-erosion, anti-scouring capability are strong, can prolong the time of staying of molten steel in bag, help inclusion floating, improve slab quality, avoided nozzle blocking.

The specific embodiment
See Fig. 1, Fig. 2, Fig. 3, tundish multifunctional integral flow straightener, collection slag blocking wall 1, flow straightener 5, Antileaking plate 3 and backplate 2 are one, this device is that its oral area is big, the bottom is little by six sides and the hollow uncovered six terrace with edge overall structures that the bottom surface constitutes.
With on the side that the tundish working lining contacts be not provided with several tap holes 4 at it; The device bottom surface is equipped with Antileaking plate 3.
This device is installed in tundish bottom impact zone, combine closely with the tundish cylinder-packing, prevented the damage of huge jet to cylinder-packing, anti-erosion, scouring capability are strong, because the barrier effect of each face, changed the molten steel fluidised form, reduce molten steel flow speed, molten steel is stirred in impact zone, field trash fully floats, improve casting rate of tundish, avoided nozzle blocking.The impact of molten steel is accepted in bottom surface (flow straightener 5), has the effect of current stabilization, and the Antileaking plate 3 of bottom surface installation has simultaneously strengthened leak preventing effect; The side that contacts with cylinder-packing (backplate 2) is removed current stabilization and is had protective action again; The side that contacts with the tundish working lining (slag blocking wall 1) do not keep off slag in the long nozzle district, avoided slag to flow into crystallizer, according to the different requirements of smelting, be provided with the tap hole 4 at several different sizes and inclination angle thereon, tap hole is positioned under the operating fluid level, and movement locus changed after the molten steel that stirs flowed into pouring area from tap hole, and dead space volume obviously reduces, basically eliminated short-circuit flow, made the molten steel temperature at each mouth of a river more even.
