Definitions

  • the invention pertains to a fluid-cooled mold which is particularly suitable for electroslag remelting installations wherein molten metal, for example steel, is stored in the casting space.
  • molten metal for example steel
  • the inner wall space of the mold is lined with plates.
  • the larger fluid-cooled molds in the installations for the manufacture of cast ingots (respectively strands) having rectangular, square or polygonal cross sections have, generally, plates lining the inner wall surfaces of the molds and these plates are generally connected to each other by means of screwed connections.
  • the hot metal causes (particularly in those areas of the wall lining which absorb inpacts) thermal stresses during the cooling of the hot molten metal, for example molten steel, which effects the formation of gaps through which the hot molten metal or slag may leak out.
  • a mold construction of the aforedescribed type is obtained by providing an intermediate member between adjacent plates which have edge portions that overlap the surfaces of the plates facing the casting space, and said intermediate members extend longitudinally relative to the mold.
  • FIGURE illustrates a cross-sectional partial schematic view of the mold wall construction for electroslag-remelting of steels.
  • the mold construction of the invention includes a cylindrical mold wall 1 having stiffening ribs 1' welded to the outer periphery of the mold wall I. On the inner side of the mold wall 1 there are disposed eight identical plates 2 having mating curved convex surfaces. These plates 2 are preferably made out of copper. The plates 2 are secured to the wall I by non-illustrated screws or bolts.
  • Each intermediate member 3 has a substantially key-shaped cross section.
  • Each intermediate member 3 is provided with a leg 4 which extends between adjacent plates 2, and a flange 5 which bears against the adjacent inner wall surfaces 2' of the plates 2.
  • the flange 5 which extends longitudinally relative to the mold (that is perpendicularly to the plane of the FIGURE.
  • the width b of the leg 4 of the intermediate member 3 is smaller than the minimum distance a between adjacent plates 2.
  • the surface of the intermediate member 3 facing the casting space 10 is convexly curved.
  • the angle a between the surface 3' facing the casting space 10 of the intermediate member 3 and the adjacent surface 2" of the plate 2 is at least 30 and preferably 45 to
  • Each intermediate member 3 is secured to the wall 1 by means of a bolt 6 having a hexagonal head 7 which can be screwed into the leg 4 of the intermediate member 3.
  • Two dishshaped springs 8 are disposed between the 7 and the wall 1 on each bolt 6.
  • Each intermediate member 3 has a channel 9 and each plate 2 is provided with a plurality of channels 9 all of which have circular cross sections and which extend preferably longitudinally relative to the mold to conduct a cooling medium, for example water, therethrough.
  • the casting space 10 has therefore generally an octagonal shape.
  • casting spaces having substantially square or rectangular cross sections can similarly be constructed in accordance with the invention.
  • the plates lining the inner wall of the mold may have surfaces facing the casting space which can be non-planar, for example convexly curved.
  • the mold construction of this invention is suitable not only for electroslag-remelting installations but for example also for continuous casting installations.
  • each leg of each member extending into the gap between the associated plates, the flange of each member covering the edge portions of the associated plates which confront said casting space, the width of each leg being smaller than the minimum width of the gap between the associated plates.
  • each intermediate member is connected to the mold by means of at least one bolt threadably mounted on said leg and extending through the mold; said bolt extending perpendicularly relative to said flange of said intermediate member.
