Description
Technical field
The utility model relates to a kind of continuous casting tundish inward turning type turbulence inhibitor.
Background technology
Along with slab quality is required to improve constantly, continuous casting tundish more and more comes into one's own as the important reaction vessel of cleaning molten steel.In recent years, people have adopted tundish turbulence controller, molten steel injects the process of tundish, tundish turbulator has played the effect of stable molten steel, reduce the turbulent extent of tundish molten steel, improve the flow behavior of Metal in Tundish, extend the time of staying, promote inclusion floating, and can prevent molten steel from opening the splash of molten steel while watering and cause the secondary oxidation of molten steel.
Traditional turbulence inhibitor for suppressing tubulence energy, prevent that molten steel from splashing, improving in the flow regime of tundish and played very important effect.But it is very limited for the floating of field trash, to remove ability, and the field trash of small particle diameter is difficult to floating.
Existing a kind of turbulence controller for continuous casting middle ladle, comprises that controller body is formed on the intrinsic hollow chamber of controller.The external shape of controller body is cube, cylinder, lower large little Rotary-table or prismoid, and is provided with upper end outlet.The bottom outside of controller body can be provided with the edge of a wing.The bottom surface of hollow chamber is plane or wavy surface, between its side and end face and bottom surface, adopts rounding off to be connected, and the bottom of hollow chamber is provided with the rotary through hole of water conservancy diversion obliquely connecting with this external surface of controller.
Summary of the invention
The purpose of this utility model is for above-mentioned present situation, aims to provide a kind of simple in structurely, processes easy, easy to operate; Can in inside, form the velocity field of eddy flow, effectively remove field trash, effectively reduce the continuous casting tundish inward turning type turbulence inhibitor of tubulence energy.
The implementation of the utility model object is, a kind of continuous casting tundish inward turning type turbulence inhibitor, comprise controller body and be formed on the intrinsic hollow chamber of controller, described hollow chamber upper end is provided with outlet, and hollow chamber's bottom surrounding is provided with the cube eddy flow catch that rotation direction is consistent.
The utility model is by arranging in hollow chamber bottom the cube eddy flow catch that rotation direction is consistent, make to form through the molten steel of tundish long nozzle injection the velocity field of an eddy flow, met stable molten steel, reduce tubulence energy, promoted significantly again the collision probability of non-metallic inclusion, Collision coagulation better floats after growing up, and is more conducive to remove.
Advantage of the present utility model is mainly reflected in the following aspects:
1, simple in structure, process easy, easy to operate;
2, turbulent flow control is effective, can effectively prevent the secondary oxidation of liquid fluctuating and molten steel;
3, in inside, form the velocity field of eddy flow, promote field trash to collide the floating of growing up, the more effective removal of energy;
4, the velocity field of eddy flow can activate the flow regime of impact zone molten steel, extends the time of staying of molten steel;
Experiment showed, that the utility model can effectively reduce short-circuit flow, field trash has enough floating interval of floating docks.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation,
Fig. 2 the utility model vertical structure cutaway view,
Fig. 3 be the A-A of Fig. 1 to view figure,
Fig. 4 is that the utility model is at tundish installment state figure.
The specific embodiment
With reference to figure, comprise controller body 2 and be formed on the hollow chamber 4 in controller body 2, described hollow chamber upper end is provided with outlet 5, and hollow chamber's bottom surrounding is provided with the cube eddy flow catch 3 that rotation direction is consistent.The width of peristome 5 is 3-7 times of tundish long nozzle internal diameter, is preferably 5 times.Controller body 2, peristome 5 and hollow chamber 4 are shaped as cube, cylinder or up big and down small Rotary-table.
The cube eddy flow catch 3 of hollow chamber bottom surrounding setting be arranged on tundish long nozzle under, overlap with long nozzle 6 center lines, can effectively reduce tubulence energy, prevent that liquid fluctuating is excessive.
Two cube eddy flow catch are set in hollow chamber's each direction of 4 bottoms, and in one of them direction, two cube eddy flow catch spacing are consistent with the cube eddy flow catch spacing in other direction, and not with lateral vertical.The height of the cube eddy flow catch of hollow chamber bottom is the 1/5-3/5 of hollow chamber's height, is preferably 2/5, and wide is the 1/5-3/5 of eddy flow catch height, is preferably 2/5; Length is 1.5-2.5 times of eddy flow catch width, preferably 2 times.With the angle of corresponding hollow chamber sidewall be 30 °-60 °, be preferably 45° angle.The cube eddy flow catch of hollow chamber 4 bottoms leaves eddy flow catch height 1-2 spacing doubly with corresponding sidewall, and (claim 4) is preferably 1.5 times of eddy flow catch height.All cube eddy flow catch 3 and the integrated molding structure of described stream controller body 2, and material is refractory material (claim 9).
Molten steel injects the utility model, can in middle chamber, form the velocity field of an eddy flow, thereby generation centrifugal force, and field trash in molten steel is assembled under this centrifugal action to pivot, effectively promoted the collision probability of field trash, and the field trash of Collision coagulation after growing up is more conducive to floating and is more conducive to remove, finally reached the object of cleaning molten steel.
