Abstract
The utility model belongs to the field of the continuous casting of steel and iron metallurgy and particularly relates to a V-shaped blocking wall suitable for a T-shaped and approximately trapezoid-shaped continuous casting tundish. The V-shaped blocking wall comprises two symmetrically arranged deflection separating walls, wherein the cross sections of the deflection separating walls are trapezoid-shaped; and upper deflection holes, middle deflection holes and lower deflection holes are arranged on the deflection separating walls and are provided with upward inclination angles. With the adoption of the technical scheme, the average retention time of molten steel in the tundish can be prolonged, so that the V-shaped blocking wall is beneficial to separating impurities, particularly tiny impurities; besides, no holes are arranged at sections of the tops of the deflection separating walls, so that ladle slag and turbulent flow in a pouring impact area can be separated, so that the liquid level of one side of the tundish close to a water slot is kept quiet, the molten steel is prevented from the secondary oxidization of steel slag, and the ladle slag is prevented from being carried into a crystallizer, therefore, the quality of the molten steel is effectively guaranteed.
Description
Technical field:
The utility model belongs to Ferrous Metallurgy continuous casting field, relates in particular to the V-arrangement barricade of a kind of T of being applicable to shape and approximate trapezoid continuous casting tundish.
Background technology
In continuous casting manufacturing technique, molten steel in the ladle constantly flows in the tundish, because the kinetic energy effect of molten steel, the MOLTEN STEEL FLOW rather unstable in ladle nozzle zone, slag often is involved in the molten steel, cause continuous casting billet internal soundness defective, for preventing the generation of this phenomenon, at present, in the steel ladle pouring zone of tundish, generally take to be provided with shock plate, the way of stiffener and barricade, pouring molten steel spills in the tundish through barricade in the space that shock plate, stiffener and barricade surround again, extenuates the impact of molten steel and seethes.The setting of barricade, the molten steel volume slag phenomenon that the reduction steel ladle pouring causes is played a role, but also exist the unsettled shortcoming of effect simultaneously, barricade constantly is subjected to the erosion of washing away of molten steel in the process of cast, it is more and more shorter that barricade can become, behind the cast certain hour effect of barricade just not obvious even do not work.
The utility model content
The purpose of this utility model provides a kind of mean residence time of molten steel in tundish that prolong, and helps field trash, the V-arrangement barricade that the T shape of the especially tiny separation that is mingled with and approximate trapezoid continuous casting tundish are used.
The technical solution of the utility model is: a kind of V-arrangement barricade that is applicable to T shape and approximate trapezoid continuous casting tundish, this V-type barricade comprises 2 symmetrical water conservancy diversion partition walls, the cross section of described water conservancy diversion partition wall is trapezoidal, be distributed with the last pod apertures that the inclination angle all makes progress on the described water conservancy diversion partition wall, middle pod apertures and following pod apertures.
Further, described pod apertures, described middle pod apertures and the described pod apertures down of going up is circle.
Further, the described diameter of going up pod apertures is 80-90mm, and the diameter of described middle pod apertures is 80-90mm, and the described diameter of pod apertures down is 103-118mm.
Further, the described inclination angle number of degrees of going up pod apertures are 15-25 °, and the inclination angle number of degrees of described middle pod apertures are 25-35 °; The described pod apertures inclination angle number of degrees down are 40-50 °.
The beneficial effects of the utility model are: owing to adopt technique scheme, the utility model can prolong the mean residence time of molten steel in tundish, helps field trash, the especially tiny separation that is mingled with; The top of water conservancy diversion partition wall does not have the hole for one section, can isolate ladle slag and beam impact zone turbulent flow, makes the liquid level by middle water containing opening one side keep tranquil, avoids molten steel to be subjected to the secondary oxidation of slag, and prevents that ladle roughing slag is brought into crystallizer.The quality of the effective molten steel that guarantees.

The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further.
Fig. 1, Fig. 2, Fig. 3 are the structural representation of embodiment of the present utility model.As Figure 1-3, a kind of V-arrangement barricade that is applicable to T shape and approximate trapezoid continuous casting tundish of the utility model, this V-type barricade comprises 2 symmetrical water conservancy diversion partition walls 1, the cross section of water conservancy diversion partition wall 1 is trapezoidal, it is pod apertures 2 on 25 ° the circle that water conservancy diversion partition wall 1 is provided with the inclination angle number of degrees, and the inclination angle number of degrees are pod apertures 4 under the middle pod apertures 3 of 30 circle and the circle that the inclination angle number of degrees are 45 °.
Design of the present utility model and use principle are: the V-arrangement barricade of being made up of two water conservancy diversion partition walls in T shape tundish and approximate trapezoid tundish, on the water conservancy diversion partition wall, open the pod apertures that has certain angle, when steel flow during through pod apertures, pod apertures is adjusted the MOLTEN STEEL FLOW direction, impel and be mingled with come-up, simultaneously can prolong the mean residence time of molten steel in tundish, help field trash, the especially tiny separation that is mingled with; The top of partition wall does not have the hole for one section, can isolate ladle slag and beam impact zone turbulent flow, makes the liquid level by middle water containing opening one side keep tranquil, avoids molten steel to be subjected to the secondary oxidation of slag, and prevents that ladle roughing slag is brought into crystallizer, as shown in Figure 4.
