Definitions

  • the invention relates to side strips of an adjustable plate mold for continuous casting of slabs, especially for steel, between the broad sides of the mold clampable and arranged with a side facing away from the mold cavity Adjustment device are connected.
  • An adjustable plate mold for continuous casting is known from DE-OS 23 10 615 with a support frame and supported therein, provided with cooling devices, the Longitudinal and transverse walls delimiting the mold cavity with an adjusting device, associated with a clutch to interrupt the positive connection and the coupling is a movement of the clamped during the casting operation Cross wall opposite the stop surfaces towards the cavity and back allowed.
  • a cooling device is provided between the support plates and the mold walls firmly connected to it - Both the narrow sides and the broad sides of those known from this document Chill mold - a cooling device is provided.
  • From DE-OS 24 15 224 is a method for controlling the cooling capacity of Narrow side walls in plate molds in continuous casting are known, the Narrow side walls are clamped between broad side walls, and in front The mold cavity begins to pour between the narrow side walls with an in Strand direction converging and the steel quality and strand width adapted casting cone is provided, which can be specified during the casting operation is adjustable.
  • a narrow side wall consists of a copper plate facing the mold cavity, which is firmly connected to a support plate.
  • a mold wall is known from EP 0 086 405, which consists of a copper plate and a flexible composite plate provided with cooling channels.
  • the copper one is used for Form cavity indicating plate intimately connected to a support wall.
  • the invention has set itself the goal of a device to create and to provide a corresponding procedure, in which with simple constructive means a quick and safe change of the Slab format of a slab produced in a plate mold with regard to its Thickness can be carried out.
  • the invention achieves this goal by the characterizing Features of device claim 1 and method claim 11.
  • the side strips are made of an interchangeable part and a holding part built up.
  • the interchangeable part consists of copper and has a U-shaped Shape, with the two legs on the side facing away from the mold cavity are arranged.
  • a holding part protrudes into the free space of the U-shaped interchangeable part
  • Press elements are releasably connectable to the legs of the interchangeable part.
  • membranes or also come as pressing elements Springs are used, the latter by hydraulic elements when changing of the interchangeable parts are compressed and during operation on the Support the inside of the thighs.
  • the legs are provided with cams, so that they have an L shape.
  • the pressing elements are supported on the side facing the mold cavity and press the End face of the holding part against the inside of the copper Exchange part.
  • the contacting surfaces of the holding part and the interchangeable part are cooling channels designed. Without reducing the cooling capacity, an area, preferably that of the holding part, be flat.
  • the sealing between the channels is sufficient by the intermediate webs viewed, since small leakages cooling the copper Do not reduce replacement parts.
  • the legs of the U-shaped interchangeable parts are shaped so that they are exactly the Adjust the inside surface of the broad sides of the mold. With the same internal structure of the Holding part these can be securely connected to the interchangeable part without one The shape of the holding parts must be changed.
  • FIG. 1 shows a mold cavity 13 which extends from the broad sides 11 and 12 and the Sidebars 21 and 22 is formed.
  • the broad side 11 is flat and can be adjusted via broad side 51 and 52 are moved.
  • the broad side 12 shows a domed mold, in which left part of the mold wall is flat and curved in the right part.
  • the broadside 12 can be moved via broadside adjustments 53 and 54.
  • the side strips 21 and 22 can be clamped between the broad sides 11 and 12.
  • the side bar 21 is made of the interchangeable part 23, which is U-shaped configured and has straight-sided legs, and the holding part 27th built up.
  • the holding part 27 On the end face of the holding part 27 channels 41 are incorporated, which Half bores 42 in the interchangeable part 23 and corresponding half bores 43 in the holding part 27.
  • One of the channels 41 is provided with a coolant supply 44 and another channel connected to a coolant discharge 45.
  • the pressing element 31 is a unit of a spring 33 and a piston-cylinder unit 34 constructed.
  • the piston-cylinder unit 34 is actuated only for the time at which the spring 33 is relaxed and the interchangeable part 23 is detached from the holding part 27 or put back on.
  • the channels 41 are made exclusively in the U-shape Copper existing interchangeable part 23 introduced.
  • the channels 41 are in turn via a coolant supply 44 and a coolant discharge 45 connected to a coolant device, not shown.
  • the side bar 21 is with a narrow side adjustment 61 and the side bar 22 with a sidebar adjuster 62 connected.
