Definitions

  • the present invention relates to an apparatus and a method for casting strips of metal, in particular steel, in which the molten metal is fed from a pouring nozzle, which preferably corresponds to the strip width, onto a continuously moving, cooled conveyor belt and the nozzle mouth with its plane to the thickness of the metal strip to be cast, ie is adjustable to an acute angle to the conveyor belt level.
  • a pouring nozzle which preferably corresponds to the strip width
  • a continuously moving, cooled conveyor belt and the nozzle mouth with its plane to the thickness of the metal strip to be cast ie is adjustable to an acute angle to the conveyor belt level.
  • the object of the present invention is to improve the quality of the thin steel strips that can be produced with such a system and to improve the system in terms of manageability and operational safety.
  • the invention therefore proposes that the Distributor designed as a double chamber vessel, at least the pouring chamber provided with the pouring nozzle is sealed gas-tight above the melt and is connected to a pressure-controllable gas source, that the pouring nozzle is followed by a position-adjustable, adjustable smoothing roller, at least one distance measuring device on the pouring nozzle for determining the position of the pouring nozzle Cooling belt is provided and is connected via a controller with means for changing the position of the distributor.
  • the Distributor designed as a double chamber vessel, at least the pouring chamber provided with the pouring nozzle is sealed gas-tight above the melt and is connected to a pressure-controllable gas source, that the pouring nozzle is followed by a position-adjustable, adjustable smoothing roller, at least one distance measuring device on the pouring nozzle for determining the position of the pouring nozzle Cooling belt is provided and is connected via a controller with means for changing the position of the distributor.
  • the distance measuring device is a dynamic pressure measuring device and the measuring opening is arranged in the plane of the outlet opening of the casting nozzle in the wall of the casting nozzle which is assigned to the strip inlet side and which Outlet opening of the pouring nozzle is arranged inclined to the surface of the cooling belt and the angle of inclination opens in the direction of strip withdrawal.
  • means are arranged in the strip take-off direction behind the casting nozzle, with which the thickness of the cast strip can be detected and that the measured values are compared in a control unit with predetermined target values and the regulator on the gas source in the sense of a Pressure change acts to regulate the intended strip thickness by controlling the melt flow rate.
  • the means for determining the strip thickness is in particular a radiometric measuring device.
  • the radiometric measuring device can be connected to a further controller, which is connected to actuators by a height-adjustable support element arranged below the cooling belt. This support element is in particular below the pouring nozzle and can also be used to control the strip thickness.
  • each measuring device is connected to the corresponding actuating drives of one supporting element each via a controller.
  • the distance measuring devices mentioned at the outset are arranged in the outer region of the pouring nozzle in order to prevent the strip from tilting relative to the pouring nozzle and to create a thick band that is uniform across the entire width.
  • the thickness of the cast strip is measured, the measured value is fed to a regulator and, after comparison with a predetermined setpoint characterizing the thickness of the strip, the gas pressure in the pouring chamber of the distributor vessel in connection is regulated with the flow rate of the melt into the pouring chamber.
  • the above-described method for operating a pouring device can be characterized in a further embodiment of the invention, starting from the previously described generic type, in that the distance of the pouring nozzle is measured by means of a dynamic pressure measurement of a gas jet emerging from a measuring opening in the plane in the outlet opening, a the measured value of Signal corresponding to the dynamic pressure is fed to a controller and, after comparison with a target value which characterizes the distance of the nozzle from the cooling belt, actuating means acting on the distributor are actuated in the sense of keeping the measured value constant or the distance between the casting nozzle and the cooling belt surface.
  • the thickness of the cast strip is measured by means of several thickness gauges in the vicinity of the pouring nozzle distributed over the bandwidth, the measured values of the individual measuring instruments with a predetermined setpoint characterizing the thickness of the strip in one measuring device each assigned controller and, in the event of deviations from the setpoint, supplied to the actuator of the respective support element assigned to the thickness measuring device and opposite the casting nozzle for setting a desired profile and is set.
  • Fig. 1 shows a casting device for the continuous production of metal strip 19, consisting of the endless cooling belt 9, which is guided over transport rollers 20, 21 and driven in rotation.
  • a cooling or smoothing roller 1 is arranged above the cooling belt 9 and its position relative to the cooling belt 9 can be changed by actuating cylinders 22.
  • the cooling belt 9 including the transport rollers 20, 21 is mounted on a frame 2 which is adjustable in the inclination to the horizontal.
  • the frame 2 is articulated on one side, with an articulated axis 4, which extends transversely to the tape take-off direction and rests on the opposite side on vertically arranged hydraulically operated actuating cylinders 16.
  • a gas source is designated, which is connected to the outlet chamber 3 ⁇ .
  • the distribution vessel 3 is also adjustable in position.
  • the distributor vessel 3 consists of an inlet chamber 3 'and an outlet chamber 3 ⁇ . At the outlet chamber 3 ⁇ , the pouring nozzle 7 is arranged.
  • the pouring chamber 3 is sealed gas-tight above the melt.
  • the distributor 3, which is designed as a double-chamber vessel, is separated into the areas of the pouring chamber 3 'and the pouring chamber 3' by a central wall 23 which projects from above into the distributor and into the melt.
  • the movable carriage 6 carrying the distributor 3 is mounted on the frame 2.
  • the distributor 3 can be adjusted in height by means of a hydraulic cylinder 13.
  • the hydraulic cylinder 13 is included in a control circuit which includes the regulator R1 and a dynamic pressure measurement of a gas jet emerging at the casting nozzle 7, as shown in more detail in FIG. 3.
  • the distance measuring device 11 with the measuring opening 11 ' is arranged on or in the wall of the casting nozzle 7 assigned to the belt inlet side.
  • the dynamic pressure of the gas emerging at 11 'as a measure of the distance of the pouring nozzle 7 from the cooling belt 9 is fed to the controller R1.
  • the controller R1 controls the hydraulic cylinder 13 in the sense of keeping the distance of the pouring nozzle 7 from the surface of the cooling belt 9 constant.
  • the pouring nozzle 7 is immediately downstream of a thickness measuring device 14 in the direction of strip travel for determining the thickness of the metal strip 19 produced.
  • the thickness measuring device works according to the radiographic method and accordingly has transmitters and receivers which are arranged above or below the strip.
  • the measuring device 14 is connected to the pressure-controllable gas source 24 via the regulator R2.
  • the bath level of the melt 25 can be regulated via the gas pressure in the pouring chamber 3 ⁇ and thus the amount of outflow from the pouring nozzle 7 leaking metal.
  • the “gas source” is operated as a connection to a vacuum chamber.
  • the measuring device 14 is also connected to a further controller R4, which carries adjusting means for influencing the distance from the support elements 18 arranged below the cooling belt 9.
  • the support elements 18 in the form of a continuous roll or a roll consisting of individual sections are arranged in the region of the outlet opening of the pouring nozzle 7.
  • the controllable position of the support elements 18 also makes it possible to influence the thickness of the band 19 to be produced. In the event that the support element 18 consists of several individual rollers, a corresponding number of adjusting elements 15 are of course required.
  • FIG. 4. 4 shows the pouring nozzle 7 with individual rollers 181, 182, 183 arranged below the belt 9.
  • Each roller is assigned a corresponding actuating means 171, 172, 173, each of which is connected to its own controller R41, R42, R43.
  • R41, R42, R43 Such a breakdown of the support elements naturally makes it necessary for a corresponding number of thickness measuring devices 14 to also be present, so that each thickness measuring device 14 is assigned a corresponding supporting roller. This division makes it possible to achieve a finer adjustment and influencing of the strip thickness over the strip width.
  • FIG. 2 which detects the belt speed of the cooling belt 9, feeds the belt speed to a controller R3 and acts on an actuating cylinder 16, with the aid of which the inclination of the casting belt can be regulated as a function of the belt speed.
