  • the invention concerns a liquid-cooled continuous-metal casting chill mold, made of plates, whose cross section is variable, and in which at least two of the plates are composed of integral plate units.
  • a plate-type chill mold for the casting'of rectangular lengths of metal is known-namely German Pat. No. 1,125,594.
  • This patent there are broad sides and narrow sides and dimensions.
  • the latter consists of individual plate units having their own cooling water system.
  • the plate units have parallel edges, and are joined together by a tongue and groove. When worn, they can be replaced.
  • each narrow side consists of an individual plate unit which is adjustable. By means of two adjusting screws disposed at the upper and lower ends, and associated adjustingnuts, the taper can also be adjusted.
  • This known chill mold permits casting rectangular lengths of metal of different formats.
  • the changeover from one cross section of the length of metal to another cross section is however possible only by disassembling the chill mold.
  • the time required for a change of format, when interchanging chill molds, can therefore not be diminished by this known arrangement.
  • the continuous-casting chill mold of said Austrian Pat. No. 233,187 also has the same drawback as the German patent. With it like the German patent, the narrow sides have to be shifted inside the overlapping broad sides. Thus in order to change the format of the cast length of the metal intermediate walls can be inserted between the narrow sides, and they divide up the hollow space of the mold. The insertion and the shifting of the intermediate walls can however be done only after the chill mold is disassembled. v 7
  • the present invention therefore deals with the fundamental problem of creating a continuous chill casting mold in which adjustment of the mold plates, for adaptation to the desired format of the cast length of the metal can be done in a simple way and without taking the mold apart.
  • this simplified construction is made in that the plates (mold walls) which consist of integral plate units are located opposite one another.
  • the plate units are delimited by a surface running at a slant relatively to the axis of the length of metal being cast, and are arranged displaceably to one another on this surface.
  • a rotatable spindle piloted in two oppositely-threaded nuts, and having pins fastened in them, each of which engages in one of the plate units.
  • For the attachment of the plate units there are slanting slot-type guideways provided in these units and there are fastening screws, connected through the plate units to a back.
  • the back is composed of two parts set one behind the other, and which are held under stress opposite ohe another by screws having tapered nuts.
  • the plate units When the spindle is held in position and rotated, then the plate units shift relatively to one another.
  • the plate composed of the plate units hereby becomes wider or narrower, depending on the direction in which the spindle turns.
  • the meansfor attaching the plate units to the supporting back are arranged so that they do not permit the ability of the plate units to shift.
  • the plates of the chill mold according to the invention may be positioned without the mold having to be disassembled. In this way it has become possible to make an adaptation to any desired format of cast length of metal in a short time, for example during the inevitable stoppage of the equipment between two pouring operations.
  • the adjustment of the chill hold as to thickness is followed by an adjustment of the guide rollers and transport rollers following the mold. It is for example possible to use for this purpose the means provided in German Pat. No. 1,217,030.
  • the opposite guide rollers are in this case connected by links, whose angular setting has to be changed depending on the thickness desired for the length of castme'tal.
  • FIG. 1 shows a side view of a continuous casting chill mold in accordance with the invention
  • FIG. 2 is a plan view of the mold of P16. 1;
  • flG. 3 shows, on a larger scale, a portion of the plan view
  • FIG. 4 shows, likewise to a larger scale, the side view of a mold plate
  • FIG. 5 represents a partial section through FlG. 4;
  • FIG. 6 shows the plan view of a chill mold with an inserted intermediate wall
  • FIG. 7 shows the intermediate wall to a larger scale.
  • the chill mold has plates 1 and 2, which represent the broad sides of the slabbing chill mold. Between the overlapping board sides are damped the narrow sides or plates 3 and 4. The plates 1, 2, 3, 4 are held together by bolts 5. The chill mold is supported on the frame 6. The plates 1 and 2 have a continuous wall which comes into contact with the fluid material being cast. This wall is cooled at its rear side with water, and is supported by a reinforced frame.
  • the plates 3 and 4 are adjustably positioned with the plates 1 and 2.
  • a drive 7 associated with the frame 6 serves for this purpose.
  • This drive which has been heretofore known, consists of a worm shaft 8 which drives two worm wheels 9. These worm wheels are associated with two nuts 10, which are not shown in detail, in each of which nuts is piloted on a spindle 11 and 12 respectively.
  • the spindles 11 and 12 engage at the upper and lower ends at the back 13 of the plates 3 and 4 respectively. Because the screw thread of the lower spindle 12 has a pitch less than that of the upper spindle 11, when the plates 3 and 4 are shifted in position their taper is at the same time also changed.
  • the opposite plates 3 and 4 are in accordance with the invention each composed of two independent plate units 14 and [5.
  • Each plate unit itself consists of one wall which comes into contact with the fluid material being cast and of a rear cooling-water system.
  • the plate units 14 and 15 have approximately the shape of right triangles. Their hypotenuses abut with the result that a slanting contact surare pressed firmly against one another.
  • the plate units 14 has a bore 16, into which is introduced a spindle 17.
  • the spindle 17 is mounted so that it is able to turn, by means of a ring 18, having at the middle of its length a fork, i.e. a bearing yoke 19, which surrounds onehalf the ring 18.
  • the bearing yoke 19 is fastened to the back 13 and engages in a recess 20 in the plate units 14,15.
  • the spindle l7 moreover is provided at its upper and lower ends with screw threads of opposite pitch. Round these screw threads the nuts 21,22 engaging same which are sent on lateral pins 23,24.
  • the pins 23, 24 by these means engage respectively in plate units 14 and 15. Thus the pin 23 engages in the plate unit 14 and the pin 24 engages in the plate units 15.
  • the plate units 14 and 15 are connected with the back.
  • the back 13 is moreover divided in the direction of the cast length of metal.
  • the tapered nuts 32, 33 are tightened up, then the two parts 13a, 13b of the back are forced apart from one another against the force of the fastening screws 25 to 28.
  • the fastening of the plate units 14, 15, to the back 13 is effected, and the fastening screws 25 to 28, after the mold is once set up, do not need to be loosened or tightened again.
  • the hollow space of the mold is divided by inserting an intermediate wall 34, as shown in H6. 6.
  • the intermediate wall 34 consists of two associated plate units 14, 15, which are fastened on a divided back 13a, 13b disposed between them in the way described.
  • the back 13a, 13b lies against the broad sides 1, 2, and is fastened there.
  • the adjustment of the hollow space in the chill mold for adaptation to the desired format of the length of the case metal is done in the following way.
  • the bolts are loosened.
  • a loosening of the tapered nuts 32, 33 gives the plate units 14 and a certain freedom to move.
  • the spindle 17 By turning the spindle 17 all the plate units 14 and 15 become displaced relatively to one another along the slanting contact surface through the interaction of the nuts 21, 22 and pins 23, 24.
  • the hollow space in the chill mold is enlarged or is diminished;
  • the plate units 14 and 15 slide with their slanting slot-type guideways 29 over the stationary fastening screws 25 to 28.
  • the chill mold is changed in width in that the plates 3 and 4, by the aid of the spindles 11, 12, are moved toward or away from one another between the overlapping plates 1,2.
  • the adjustment of the plates is done in a short time, and without having to disassemble the chill mold.
