Definitions

  • the invention relates to a liquid-cooled mold for the continuous casting of metals, in particular steel.
  • tubular molds are usually used for the production of billet, bloom and round strands, and plate molds are used for the production of slabs.
  • the molds are oscillated in the casting direction.
  • a sinusoidal mold movement is preferred, the speed of the downward movement of the mold being greater than the generally constant strand withdrawal speed (negative strip).
  • the frequency and the stroke height of the oscillation movement are matched to the strand withdrawal speed.
  • a frequency of approximately 100 vibrations per minute at stroke heights (amplitude of one vibration) of 4 to 15 mm are common values.
  • higher numbers of oscillations have also been proposed. The realization has so far failed due to the size of the mass to be moved.
  • the mass to be moved is approx. 30 t for the specified slab format.
  • the invention has for its object to reduce the suspension of the molds with the inclusion of the oscillation device in the mass to be moved in liquid-cooled, oscillatably mounted molds in order to be able to set higher vibrations with the least possible power requirement.
  • the plate mold shown in Fig. 1 consists of the shaping wall 1 in the form of copper plates, which form the mold cavity for the strand to be produced.
  • the copper plates 1 are attached to support plates 2.
  • the copper plates 1 are water-cooled.
  • the cooling liquid is supplied to or removed from the support plates 2 of the broad sides via flexible lines and the connections 14 and the flow channel 15 (FIG. 2).
  • the copper plates 1 of the narrow sides 3 can be supplied in the same way.
  • the narrow sides 3 are clamped between the broad side plates 1, 2 and are carried by adjusting devices 5, with which the width of the slab to be produced is fixed, which in turn are fastened to clamping elements 13, which connect the support plates 2 outside the flow channels 15.
  • a multiplicity of spring elements 7 - here leaf springs - are fastened on one side.
  • laminated bodies which are formed from leaf springs with vulcanized-in intermediate layers of elastomers can also be used as spring elements.
  • the leaf springs are evenly spaced from one another over the surface and extend transversely to the casting direction. They have a much lower rigidity in the casting direction than in both transverse directions.
  • the leaf springs are on with their other ends a support plate 6 attached.
  • the support plates 6 are in turn fastened by spring-loaded, hydraulically decoupled adjustment and adjustment elements 11 (see FIG. 5) to a stationary base frame 12 encompassing the support plates 6 and the narrow side plates 3.
  • the adjustment and adjustment elements 10, 11 provide an adjustment and alignment of the broad sides to different slab thicknesses with corresponding narrow side plates 3.
  • cooling water is supplied to the oscillating plates (1, 2, 3) from the base frame (12) via hose connections 14 through the support plates (6) and a flow channel 15 provided on the back of the support plates (2) . Due to the water flow over the broad sides, the use of several hose connections is possible, so that the water distribution and pressure adjustment largely take place in the non-oscillating area of the mold and the flow cross-section on the moving support plates can be minimized. It is also possible to make the upper and lower row of spring plates closed and to seal the sides with elastic elements in order to protect the components within this area from the extremely aggressive environmental influences in the area of the system.
  • the wall 1 which forms the mold cavity for the strand to be produced, consists of a copper tube of circular cross-sectional shape with a curved longitudinal axis 19.
  • tubes with a rectangular or polygonal cross-sectional shape and a straight longitudinal axis 19 can also be used become.
  • the copper pipe 1 is surrounded in a manner known per se by a water guide jacket 20 and is held by means of flanges 18 provided on the pipe ends and a tubular support plate 2 surrounding the copper pipe 1 and the water guide jacket 20.
  • the flanges 18 have a rectangular shape in plan view.
  • the spring elements 7, also formed here as leaf springs are arranged transversely to the casting direction.
  • the spring elements 7 are fastened via mounting strips 8 to a respective support plate 6 which is connected to a base frame 12.
  • the mold can be oscillated by means of a hydraulic cylinder 16, which on the one hand engages on the support plate 2 and on the other hand is supported on the support plate 6 via a connecting web 21.
  • the oscillation drive 16 is directly connected to the mass to be oscillated without the interposition of the usual intermediate gears or intermediate linkage.
  • the spring elements 7 are aligned with their longitudinal axis 7 'so that their imaginary extensions intersect at the center of curvature 22 of the mold, or in a line running through the center of curvature 22 and perpendicular to the spring element axes 7'. Since in a mold tube with a straight axis 19 the "center of curvature" is infinite, the spring elements 7 arranged one above the other and fastened to the two tube ends are generally parallel to one another.
  • the invention is of course also applicable to a tubular mold in which the cooling takes place through cooling channels running in the wall 1.
  • the tubular support plate 2 can rest directly on the wall 1 and the spring elements can be fastened analogously in the manner described for the slab mold.
  • the oscillating mass results from the strand format to be cast and the design of the crystallizer plates used. If these parameters change under other conditions, this fact can be taken into account by changing the spring parameters accordingly.
  • the following values are selected with regard to the mold:
  • Handlebar length, width and number result essentially from the available installation space and the structural design of the crystallizer plates used, different designs are entirely possible here, in which case the handlebar thicknesses must be adjusted accordingly.
  • Static countersink is understood to mean the change in position of the spring elements due to the load with the mass to be oscillated.
  • the dynamic zero position that is to say the “center of oscillation”
  • the two shaping walls are designated by 1, which accommodate the strand between them.
  • the shaping walls are attached to the support plates 2.
  • the support plates 2 are connected to the support plate 6 via spring elements 7.
  • the "constructive zero position" is denoted by a.
  • the point of application of the leaf springs 7 on the support plate is offset by the amount of the static sag.
  • the dynamic zero position b results from this.
  • the Dynamic zero position is at the same time the operating point around which the support plate 2 oscillates with the shaping wall 1, the top dead center of the oscillation being denoted by c and the bottom dead center of the oscillation being denoted by d.
  • a hydraulic cylinder is particularly recommended as an oscillation drive.
  • the hydraulic cylinder can be designed small, since basically only the friction between the mold wall and the strand shell has to be overcome.
  • the hydraulic cylinder can be operated at operating pressures below 10 bar, the cooling water system of the mold or that of the machine cooling can be used as the power source.
  • the solution that can be implemented with the invention is recommended due to the design with the smallest space requirement for use in multiple continuous casting plants with billet and bloom formats.
  • the design of the spring elements will be explained below with reference to FIGS. 9-11. It is important that the spring elements can be manufactured as coherent units during manufacture or as spring assemblies, which are then only to be inserted into the clamping jaws in a simple manner before screwing and thus fastening to corresponding brackets of the support plate or support plate. There are no differences for the assembly, whether it is a single spring in the spring element or a multiple arrangement of, for example, two or three springs. Correspondingly dimensioned intermediate layers ensure the spacing or the storage of the spring element (s) in the clamping pieces and thus the clamping jaws.
  • brackets 117 are arranged on the support plate or support plate. These brackets form support surfaces for the clamping jaws 111.
  • the clamping jaws 111 have a circular bore when viewed in cross section.
  • Clamping pieces 112, which are produced from two cylinder sections, are arranged in this bore. In their shape, as can be seen from FIG. 9, these clamping pieces are adapted to the bore in the clamping jaws and, viewed in cross-section, again have a semicircular surface lying against the inner wall of the bore and a flat surface which faces the spring element (s) ( are).
  • two spring elements 116 are provided.
  • This plane-parallel intermediate layer is adapted to the desired dimension of the spring package provided during manufacture.
  • the intermediate layers can also be made from consistently thick flat material. Deviating from the representation in FIG. 11, only one spring element is provided in FIG. 11, corresponding intermediate layers being shown here above and below. For comparison, FIG. 11 corresponds to the illustration in FIG. 9 and finally an arrangement with three spring elements can be seen in FIG. 11, in which correspondingly thinner intermediate layers are used.
  • a fitting sleeve 113 is hammered in, which then holds the spring element or the spring elements together with the clamping pieces at both ends.
  • This unit can then be inserted laterally into the holes in the clamping jaws, and then the screws indicated with 115 are passed through a corresponding hole in the clamping jaws or through the adapter sleeve and the bracket 117, and when screwing this is not only an adjustment but also also a firm connection between the spring elements and the console via the clamping pieces or clamping jaws. It is essential that - and this follows from FIG. 9 - the screws 115 have a smaller diameter than the inside dimension of the adapter sleeve. Due to the shape of the surfaces of the Clamping pieces or clamping jaws and the dimensioning of the clamping screws ensure that both axial forces and bending moments from the spring elements are transmitted to the brackets in a frictional manner during operation of the mold. The articulation described acts like a rigid connection in operation. The effect as a rotary or rotary push joint is limited to the adjustment process.
