Description
Technical field
The utility model relates to a kind of refractory container, particularly relates to a kind of current stabilization and impacts vessel.
Background technology
Tundish is the refractory material containers used in mini-mill steelmaking, and first it accept and water from ladle the molten steel got off, and then be assigned in crystallizer by molten steel.Molten steel flow speed under watering from ladle is fast, large to the impact of tundish, if directly impact tundish bottom surface not only Eroded tundish, and there will be the disadvantageous phenomenons such as the disorder of steel stream, turbulent flow, eddy current, impact cast and crystallization, have for alleviating impact erosion, controlling the current stabilization punching groove of steel stream, but current stabilization punching groove itself weathers seriously in prior art, life-span is low, and steady flow result bad.
Such as, there is the Chinese patent literature that publication number is CN201558948U, publication date is on December 23rd, 2009 in existing open file, disclose a kind of tundish current stabilizer with contractible neck, its structure is the bulk containers with inner chamber, the bottom of flow straightener inner chamber is large, oral area is little, has contractible neck between the bottom of flow straightener inner chamber and oral area, and the smallest cross-section area of contractible neck is less than the cross-sectional area of inner chamber oral area, bottom is contraction section to contractible neck, and contractible neck to oral area is expansion segment.This technical scheme can reduce the impulsive force bottom molten steel inflow flow straightener, and extend the service life of flow straightener, the eddy current that MOLTEN STEEL FLOW can be suppressed to produce, slows down molten steel flow speed, improves the stability of MOLTEN STEEL FLOW.The weak point of this technical scheme is, the bottom of flow straightener inner chamber is subject to the quiet liquid of larger molten steel and molten steel impact, bottom suffers erosion even more serious, affect the whole service life of flow straightener, and steel stream collides from the unordered outflow of oral area surrounding is relative with the molten steel ladle waters, molten steel flow is disorderly, and steady flow result is poor.
Utility model content
Weather seriously for solving existing current stabilization punching groove, the life-span is low, and steady flow result bad problem, and the utility model provides a kind of effective reduction from the tundish current stabilization punching groove of the molten steel impact ladle waters, molten steel flow steady ordered.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of current stabilization impacts vessel, comprise inner chamber and sidewall, inner chamber has a necking down, the partial cross section size of inner chamber below necking down is greater than the size of necking down and the size of inner chamber oral area, and sidewall is provided with leak, and leak place is provided with the guiding gutter of communication with cavity, one end that the width of guiding gutter is connected to leak from it increases gradually to its end, guiding gutter comprises diapire and two sidewalls, and guiding gutter diapire is provided with branching block, and branching block is arranged between two sidewalls of guiding gutter.Flow out from leak after the high-speed steel stream ladle vertically waters cushions in the lumen, flow in tundish along guiding gutter, reduce the impact of steel stream, the molten steel speed flowed out reduces, direction, by becoming level vertically downward, is conducive to the stable of steel stream, reduces the disadvantageous flow fields such as turbulent flow; Guiding gutter end is comparatively large, makes the flowing space of steel stream become large, and flows to the steel stream height reduction of tundish, and also favourable steel fluid field is stable; The molten steel flowed out is divided into two strands through branching block, after converge into one again, this process, along with the counteracting of two strands of steel stream partial velocities, reduces steel Flow Velocity, is conducive to the stable of steel stream.
As preferably, leak is arranged on lumenal cross-section size maximum, and guiding gutter is downward-sloping, guiding gutter terminal horizontal.[trend of the upper and lower molten steel of cross sectional dimensions maximum this position all oriented flowing, so the pressure be subject to and corrode comparatively large, at this position opening, effectively can unload the pressure in inner chamber, less static pressure and wash away erosion; Downward-sloping and the terminal horizontal of guiding gutter, make the molten steel of derivation flow out current stabilization when impacting vessel inner chamber, obtain the steel stream of bottom horizontal flow sheet, such steel stream flowing smooth sequential, splash few, be not easily involved in air, the secondary oxidation of molten steel is low.
As preferably, branching block upper surface and leak upper surface coincide together.Branching block upper surface overlaps with leak upper surface, makes the molten steel of outflow inner chamber be divided into two strands, and two strands of steel streams are when again converging, and the contrary velocity component in both directions is cancelled out each other, and reduces the speed of steel stream.
The beneficial effects of the utility model are: molten steel impact is lower, molten steel flow steady ordered, and splash few, be not easily involved in air, the secondary oxidation of molten steel is low.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of current stabilization impacts vessel, comprise inner chamber 1 and sidewall 2, inner chamber 1 has a necking down 11, the partial cross section size of inner chamber 1 below necking down 11 is greater than the size of necking down 11 and the size of inner chamber 1 oral area, sidewall 2 is provided with leak 3, leak 3 place is provided with the guiding gutter 4 of communication with cavity 1, one end that the width of guiding gutter 4 is connected to leak 3 from it increases gradually to its end, guiding gutter 4 comprises diapire and two sidewalls, guiding gutter 4 diapire is provided with branching block 5, and branching block 5 is arranged between two sidewalls of guiding gutter 4; The cross section of branching block 5 is circular, leak 3 is arranged on inner chamber 1 cross sectional dimensions maximum, in the present embodiment, the cross section of inner chamber 1 is circle, namely leak 3 is arranged on inner chamber 1 cross-sectional diameter maximum, and on the position of leak 3 height 1/4th below inner chamber 1, the partial lumen 1 below leak 3 position can store molten steel, reduce the bottom surface that the molten steel flowed down in ladle directly washes away inner chamber 1, reduce and corrode, guiding gutter 4 is downward-sloping, guiding gutter 4 terminal horizontal; Be provided with the transition arcs of round and smooth connection both between the tilting section of guiding gutter 4 and the horizontal segment of end, transition arcs makes steel levelling current stabilization go out, and branching block 5 upper surface and leak 3 upper surface coincide together.
As shown in Figure 1, when the utility model uses, be fixed in tundish, its opening is positioned at immediately below ladle nozzle, and molten steel flows out inner chamber 1 from leak 3 via guiding gutter 4 after cushioning in inner chamber 1, enters in tundish.
