Definitions

  • the invention relates to a continuous casting mold with the casting cross-section surrounding Kokillenplatten in which run cooling channels, wherein the Kokillenplatten are connected by means of screw elements with a water tank and screw elements consist of fastening bolts with a threaded shaft which can be screwed into mounting thread in the mold plate.
  • molds for the continuous casting of steel consist of several mold plates, which together form a cavity. In this cavity, the liquid steel is filled, partially solidified and is discharged downward. Depending on the shape of this cavity, a distinction is made between slab, Dünnbrammen-, Vorblock- or beam blank formats.
  • the mold plates which are almost without exception made of copper alloys, have very high thermal and mechanical loads. So that the mold retains its shape despite the forces acting during casting, the mold plates are attached to the back of a water tank. In particular, this should prevent the formation of larger gaps in the contact area between the individual mold plates of a mold. Also, the cooling water of the mold must not escape uncontrollably and come into contact with the liquid steel.
  • the mounting threads or tapped holes In order to ensure sufficient strength against the tearing of the fasteners from the copper, the mounting threads or tapped holes must be sufficiently deep and have a sufficiently large diameter.
  • the back of the mold plates is also required to dissipate the extremely high amounts of heat released by the solidification and cooling of steel.
  • the fastening threads may be behind the cooling level.
  • the production of drilled chill plates in comparison with mold plates with milled cooling channels is relatively expensive.
  • the depth of milled cooling channels and thus the distance between the cooling channels and the Kokillenvorderseite be changed over the length and width of Kokillenplatte and so adapted to the thermal stresses occurring.
  • the fastening bolts are each arranged with their central longitudinal axes running centrally between two adjacent coolant holes.
  • the distance of the respective outer walls of the adjacent coolant holes from one another is greater than the outer diameter of the fastening bolt or the threaded bore into which the shank of the fastening bolt is screwed.
  • the supporting threaded portion is in this arrangement in the wall between the adjacent coolant holes.
  • fastening bores and cooling channels are located next to one another in the prior art.
  • cooling holes In the direction of the heat flow in front of the threaded holes still cooling holes can be located or the cooling channels do not extend perpendicular to the height of the mold plate, but at least the next channels next to the rows of mounting holes drive around the fortifications with the smallest possible distance (slalom slot).
  • the object of the invention is to arrange or form the mounting holes and the milled cooling channels on the backs of mold plates so that a nearly uniform cooling is achieved.
  • This object is achieved according to the invention with a continuous casting mold with the casting cross-section surrounding Kokillenplatten in which run cooling channels, wherein the mold plates are connected by means of screw elements with a water tank and screw elements consist of fastening bolts with a threaded shaft which can be screwed into mounting thread in the mold plate, said the fastening thread with its central longitudinal axes are each arranged to extend between two adjacent coolant channels, the diameter of each threaded hole is greater than the distance between two adjacent cooling channels (4) and the holes for the fastening thread at a distance from the sole of the cooling channels, limiting the depth of engagement of the fastening bolts , end up.
  • the holes for the fastening threads are no longer separately adjacent to the cooling channels, but overlap partially with the cooling channels or are cut by these.
  • the fastening bolts protrude a little way into the cooling channels when they have been screwed into the fastening threads. In the area of the cooling channels, however, the fastening bolts are not in engagement with the fastening thread because it is missing there. On the other hand, the fastening thread is also in the mutually remote wall regions of the adjacent cooling channels, so that in this way the tear resistance is greater in comparison to the centrally arranged fastening threads in cooling holes.
  • the load-bearing surface x of the thread depth is defined as the bearing surface.
  • the bearing circumference is the circumference of the thread minus the circular arcs cut out of the cooling channels.
  • cooling channels are deeper than the holes for the fastening threads.
  • the channel cross-section above / below and laterally of the fastening thread can be reduced by filling pieces. In the area of the fasteners then remain islands for receiving the threaded inserts.
  • the fastening threads 2 are covered by the cooling channels 4, so surrounded slalomartig.
  • the arrangement of the fastening threads 3 is such that they are cut by the cooling channels 4 or partly overlap with them.
  • Section AA In the area where the cooling channels 4 cut the holes 3, of course, there is no mounting thread, as well as from FIG. 2 , Section AA can be seen.
  • the cut BB in Fig. 2 shows a cross section through the solid material of the mold, where the bore 3 is not cut from the cooling channel 4. In the solid material, the remaining there fastening thread 2 can be seen.
  • FIG. 2 shows the mounting threads 2 and the holes for these threads are of lesser depth than the depth of the cooling channels 4, to allow a coolant flow through the cooling channel, even with a screwed fastening bolts.
