Cl.2 B22D 41/08 OR (Inventor's UNION Patent proprietor: USS Engineers and Consuftants, Inc., Pittsburgh (United States of America) Bottom spout gate valve of the casting ladle The subject of the invention is the bottom spout It is known from the U.S. Patent No. 3,352,465 to include a bottom spout gate valve with post-oscillation motion, consisting of a complete plate segment to close the gate and a plate segment with an outlet opening for the metal. ensured the outflow of meltal with full cross-sections of the outflow opening, while it is impossible to throttle the valve of metal outflow from the casting ladle. It is known from the Polish patent description No. 95 289, the valve of the bottom outlet of the foundry limbs, containing a mounting plate connected to the bottom. The mounting plate is connected to the body, in the opening of which the upper plate is permanently mounted, and the sliding visor The plate segments of the shutter are mounted on the horizontal axis, while the bottom plate of the gate valve with the pouring spout is attached to the bottom of the computer. Hydraulic actuators are mounted on the opposite side walls of the body, and four piston rods move the plate segments of the shutter and move them between the starting position through the area of slow motion under the metal discharge tube to the discharge position. The area of the slow movement of the plate segment comprises at least half of the 20 25 from the partial opening of the metal discharge port to the fully open position. The first hydraulic actuator is adapted to the displacement of the suspension plate segment. from the starting position to the slow motion area and then to the lead position. A second hydraulic motor on the opposite side restrains the movement of the plate segment in the region of its slow motion. In some processes it is advantageous to prevent the flow of metal flowing out. One such example is the continuous casting of aluminum-quenched steel, in which the oxygen released from the steel mixes with an amount of guilline and forms alumina, which is deposited around the tundish outflow opening. The aim of the invention is to improve the design of the bottom gate of the casting ladle. The invention also aims to eliminate the drawbacks of the known solutions, in particular the rapid cut-off of the liquid metal stream flowing out of the casting casing. Such a necessity occurs in the case of the outflow of the ailiuminium steel, and especially in the flooding of the cuiristalliizateir, which is part of the uTiza | dzen! And for continuous casting of ingots. The alumina oxides formed in the process of sedation show a high degree of pinignancy to the walls of the outflow tubule and cause clogging of the effluent olives. In the continuous casting cycle, it is necessary to replace the gate valve and the metal outlet tube in the gate valve., The gate valve of the bottom outlet of the de-aeration valve according to the invention / in the koinpuis opening between the upper frame part of the body and its valley, part of plate segments which are linked to the silky hydraulical longitudinal movement of the shaft segments. ~. . According to the figure, the plate segments of the shutter have an opening for the outflow of metal, preferably with the contour of an ellipse, the long axis of which is situated in the direction of (the sliding of the guide leaves. The plate segments are connected to the guide bars). They are directly connected to the hydraulic cylinder. The shutter-plate sections mounted on the guide bars are movable behind and indirectly through the hydraulic cylinder to and from the fully open position of the metal discharge opening. The plate segments are seated on guide bars connected to the hydraulic cylinder the upper arm of the lever, articulated in the slider with the arm of the lever, mounted on the roller, at whose direction of movement of the guide strips is perpendicular to the direction of movement of the valve plate segments. The subject of the invention is visible in the example of the implementation in the drawing, Fig. 1 shows, in cross-section, the gate valve of the bottom outlet of the foundry ladle 2, a detail of the valve plate segment with the metal discharge opening of FIG. 1, in top view, FIG. 3, a detail of the valve plate segment in section 8-8 of FIG. Fig. 2, Fig. 4 - the gate valve from Fig. 1, in top view, Fig. 5 - the gate valve from Fig. 1, schematically shown in cross section with an illustrated cross-section of the valve plate segment. Fig. 1 shows a particular bottom outlet of the casting quadrant. , for example, an intermediate ladle intended to pour the crystalline-sinker in a continuous casting machine. The ladle comprises a herd mantle 1 ', a fire-resistant liner 2' and a bottom spout, the pouring opening of which is poizeCihodizi through the liner and mantle. The bottom spout of the casting cadiz is connected to the herd mantle 1 'by means of a fixing plate 3'. The bottom exhaust gate valve has a body 3 'connected to the mounting plate, consisting of a 6' frame upper part and a 9 'frame upper part, between which plate segments 11, 13' are mounted on the guide bars 7 '. A 4 'top plate with a fireproof insert is embedded in the 6' open top of the koalpuis. A valley plate 15 'of a slide with a pouring spout 16' is mounted in the hole in the lower part of the frame 9 '. The bottom plate J 655 4 15 'of the gate valve is fixed by means of a set of 10' fastening strips 38, connected by fastening screws 39 'to the lower part 9' of the body. The flexibility of connection of the fastening strips 38 to the body is ensured by support trap 37 with embedded on them with pressure springs 36 '. The guiding rails 7 'are connected by the fastening bolts 35 to the waterline 34, in which the lower arms d: 6 of the lever 33 are articulated, mounted on the roller 32, and the upper arms of the lever 31, articulated with the thrust 30 of the hydraulic cylinder 17' of transverse travel. ¬ of the trim plate segments. On the side wall of the body there is mounted a hydraulic cylinder 8 'of longitudinal displacement of the plate segments of the shutter, directly connected to the backplate of the hydraulic cylinder 8'. The guide bars can also be directly connected with the hydraulic cylinder 17 '. a different outline shape, for example round, elliptical or other. x 25 Since the long axis dimension of the hole is a function of the total stroke of the throttle mechanism, the maximum possible throttling point of the metal flow is the same for each of the different holes used. In the embodiment example shown in Figs. 1, 2, 3, 4 and the stroke of the throttling mechanism is half the dimension of the longer axis of the bore. The elongation of the bore makes it possible to use plate segments with different metal flow bore shapes in the same choke mechanism, for example with a constant stroke, avoiding excessively large degrees. choking, in which there is a deformation of the stream and the associated large erosion of the nozzle in the area below the choking point.
