Definitions
- the present invention relates to a device for regulating a flow rate, which device comprising a rectangular metal frame arranged to be able to pivot relative to a bottom wall of the ladle and a pusher cover containing a plate. fixed upper and a carriage carrying a movable plate compressed between the fixed upper plate and a flange of the pouring tube.
- Document FP-A-0202213 discloses a metal frame for a device for sliding closure of a metallurgical container for continuous casting, mainly comprising a base plate secured to the metal container and a pivoting door hinged on the base plate.
- the removable rotation hinges and the removable door locking device on the base plate allow easy access to the wearing parts, at the very place where the steel is poured.
- a pressure tapping device is provided for applying the movable plate against the fixed plate while the pouring tube is held removably against the movable plate.
- a drawback of this known device lies in the fact that the movable plate is sandwiched between two fixed elements. Such a movable plate therefore has two sliding surfaces, the first face being sliding relative to the upper plate of the pouring tube.
- the present invention aims to reduce the number of wear elements in sliding contact when adjusting the flow rate and also aims to improve the supply and exchange of a pouring tube under a ladle or under a distributor. without having to significantly modify the speed of extraction of the slab, bloom or billet.
- the present invention provides an articulated frame for a device for regulating a flow rate making it possible to bring and exchange a pouring tube as described in the first paragraph of the description.
- the articulated chassis is essentially characterized in that the carriage comprises means for guiding in a horizontal plane the pouring tube in a vertical position from a loading position towards a waiting position below the pouring orifice of the movable plate , means for pushing up the pouring tube under the pouring orifice of the movable plate in the closed position of the taphole and a device for pressing the upper plate against the movable plate.
- the push-button cover is articulated on the metal frame around second pivots.
- the device for pressing the fixed upper plate against the movable plate consists of two series of spring cartridges arranged on either side of the taphole along opposite sides of the fixed upper plate .
- the spring cartridges are held in place by a compression plate fixed removably on the pusher cover using studs.
- the originality of the device for feeding and exchanging the pouring tube according to the invention lies in the fact that the tube change is made by sliding against the underside of a movable plate forming a drawer closing system with two plates, without however forming a three-plate system as described in particular in Belgian patent nr 896,223.
- the device according to the invention offers the advantage of making it possible to adjust the steel flow rate by translation of a movable part of the sliding closure device without the tube changing device itself moving under the movable plate. This avoids any deterioration of the joint between the movable plate and the pouring tube due to friction or to the infiltration of steel.
- the pneumatic or hydraulic cylinder or cylinders which exert the forces necessary for moving the pouring tube with a view to changing the tube can be directly fixed: either at a fixed part of the machine; either to the mobile carriage of the machine; either to an external manipulator, which is not an integral part of the machine.
- the displacement of the pouring tube in a crossed movement offers the advantage of allowing the implementation of first rapid drive means of large amplitude, but little precise for bringing the pouring tubes to the immediate vicinity of the taphole and second drive means perpendicular to the first, small amplitude, but very precise for adjusting the flow rate.
- This mounting method not only allows the supply and exchange of a pouring tube, but also the easy replacement of wearing parts such as the fixed upper plate as well as the visual examination of the internal nozzle.
- FIG. 1 is a longitudinal section of a device for supplying and exchanging a pouring tube and regulating the flow, locked in the service position;
- FIG. 2 is a plan view of the device shown in Figure 1;
- FIG. 3 is a cross section along line III-III of Figure 2 of the device illustrated in Figures 1 and 2;
- - Figure 4 is a longitudinal section similar to that of Figure 1 of the device for supplying and exchanging a pouring tube and regulating the flow rate in the open position;
- - Figure 5 is a cross section along line V-V- of the device illustrated in Figures 1 to 4.
- a sliding closure device 1 which carries out and exchanges a pouring tube 2 and regulates the flow rate of a pouring bag 3 comprises a rectangular metal frame 4 arranged to be able pivot relative to a bottom wall 5 of the ladle 3 around one of its sides by means of first horizontal pivots 6 arranged transversely relative to the direction of movement of the movable plate 10 in order to adjust the flow rate.
- the first pivots 6 are engaged in lugs 30 fixed on the bottom of the ladle 3.
- the metal frame 4 supports a push-cover 7 containing a fixed upper plate 8 and a carriage 9 carrying the movable plate 10.
- the upper plate 8 is pressed down by a pressure device 12 consisting of two series spring cartridges 13, 14 arranged on either side of the taphole 15 along opposite sides of the fixed upper plate 8.
- the spring cartridges 13, 14 are retained in place by the studs 17. They are subjected to a compression preload, before the chassis 4 is raised and locked.
- the movable plate 10 is subjected to a downward thrust transmitted by the fixed upper plate 8 pushed down by a series of spring cartridges 13, 14 and it is also subjected to an upward thrust exerted by the pouring tube , subjected to the action of the pushing devices 31, which act independently of the cartridges 13, 14.
- the movable plate 10 is therefore compressed between the fixed upper plate 8 and a flange 11 of the pouring tube 2.
- the metal frame 4 is articulated with the push-cover 7 arranged to pivot down around second horizontal pivots 18.
- the carriage 9 comprises guide means 19, 20 of the pouring tube 2 erected vertically.
- the guide means 19, 20 extend in a horizontal plane. They bring the replacement pouring tube 2 from a loading position 21 located far from the tap hole to a standby position 22 located just below the pouring orifice 27 of the movable plate 10 when the latter this is in the closed position of the tap hole.
- the pushing means 31 are pushed upwards by levers 35 articulated at 36 and subjected to the action of springs 37 at their free end 38.
- the first and second pivots 6, 18 are parallel to each other. They determine an axis of rotation LL 'perpendicular to the direction of movement along arrow X of the two-plate drawer formed by the fixed upper plate 8 and the movable plate 10 during the regulation of the steel flow rate.
- the doubly articulated chassis 4 simply facilitates access to the refractory parts, in particular to the movable plate 10.
- the assembly and disassembly of the articulated frame 4 of a device for supplying and exchanging a pouring tube 2 and regulating a pouring bag 3 on the bottom wall 5 of a pouring bag 3 is as follows.
- an internal nozzle 23 is positioned in a seat race 24 of the ladle 3 from below.
- Two series 13, 14 of spring cartridges are retained in place by means of a compression plate 16 removably fixed to the upper plate 8 using studs 17.
- spring cartridges 13, 14 are compressed using a hydraulic tool not shown by pressing on the compression plate 16 and the compression plate 16 is locked using parts anchor comprising a wing nut 40. By releasing the hydraulic tools, the upper plate is released.
- the machine is closed, by folding the push cover 7 in the clockwise direction on the metal frame 4 and by folding the metal frame 4 in the anti-clockwise direction against the bottom wall 5 of the ladle 3.
- This locking of the metal chassis 4 is effected by tilting the eye screws 26 in a notch 41 of the metal chassis 4.
- the hydraulic cylinder is fixed to the movable carriage by a stud inserted in the hole 28 formed in the lug 29 of the carriage 9.
- the disassembly of the device for supplying and exchanging a pouring tube and regulating the flow takes place in the reverse order of assembly:
