Definitions

  • a liquid-cooled mold of the type in question becomes continuous casting of thin steel slabs, the cross-sectional length of which is a multiple of the Cross-sectional width.
  • At least every broad side wall is made up of one Mold cavity bounding copper plate and a steel support plate together.
  • the copper plate is on the support plate by means of transversely protruding metal bolts attached. To do this, the metal bolts penetrate the holes in the support plate. End The holes are provided with extended areas in which nuts on the Threaded ends of the metal bolts can be screwed. With their help Copper plate pulled tight to the support plate.
  • the invention is based on the object of a liquid-cooled mold for high casting speeds, especially for the Near-dimensional steel casting, to create, where the strength problems clearly in the area of the connections of the metal bolts with the copper plates are reduced.
  • the metal bolt according to claim 2 CuNiFe alloy Mn added that there is a composition of CuNi30Mn1Fe.
  • the metal bolts made of a CuNi30Mn1Fe material.
  • nickel is used as a filler metal (Claim 5).
  • the filler metal can be used as a foil between the metal studs and the copper plates are inserted. It is also possible to use the copper plates to be provided with the filler metal at the connection points or also to coat the end faces of the metal bolts. It is also possible to use nickel rings Use the metal studs on the circumference as a filler metal.
  • the copper plates of the broad side walls Groove-like grooves running parallel to the casting direction and covered by the support plates Coolant channels on.
  • Coolant channels on.
  • cooling holes can be generated by mechanical deep drilling. Through this Cooling holes transferred coolant avoids a local in continuous casting operation Temperature rise of the copper plates near the connection areas of the Metal bolt with the copper plate.
  • the cooling bores are preferably arranged in the area of the bathroom mirror.
  • the invention provides according to claim 9 that the support plates groove-like, parallel to the casting direction, covered by the copper plates Have coolant channels. There are then no coolant channels in the copper plates available. If necessary, a combination of coolant channels can also be used used in the copper plates and in the support plates.
  • the cross section is according to claim 10 of the mold cavity is larger at the pouring end than at the strand exit end Measured end.
  • the mold cavity has multiple taper.
  • a bulge may be provided which decreases in size in the casting direction. This Bulging serves in particular to hold a dip tube.
  • FIG. 1 is a liquid-cooled, only schematically illustrated Mold for continuous casting of thin steel slabs, not shown, whose cross-sectional length is a multiple of the cross-sectional width.
  • the mold 1 has two multilayer broad side walls 2 lying opposite one another and two narrow side walls 3, also opposite one another, which form a mold cavity 4.
  • the broad side walls 2 are at the pour-side end 5 of the mold cavity 4 Bulges 6 provided along a partial height of the mold 1 down be steadily reformed.
  • the cross section is at the end 7 of the strand exit of the mold cavity 4 rectangular and to the desired thin slab cross section aligned.
  • the purpose of the two opposite bulges 6 consists of the space required for a dip tube, not shown for the supply of the molten metal.
  • each broad side wall 2 has the mold cavity 4 delimiting copper plate 8 and a steel support plate 9.
  • Copper plate 8 are, as can also be seen in FIG. 2 drawn without the support plate 8 lets, parallel to the pouring direction GR, covered by the support plate 9 and groove-like coolant channels 10 to which cooling water can be applied.
  • FIGS 2 and 3 show that parallel to the coolant channels 10 also extend cooling bores 11 which can be acted upon with cooling water.
  • the cooling bores 11 run in the vertical cross-sectional planes QE of metal studs 12 made of CuNi30Mn1Fe, which are produced using the stud welding process using nickel rings 13 as a filler metal on the Back 14 of the copper plate 8 are attached. Push through the metal bolts 12 Bores 15 in the support plate 9. By screwing nuts 16 onto the thread ends 17 of the metal bolt 12, the copper plate 8 is used on the support plate 9 and committed to this. The nuts 16 are in enlarged end sections 18 of the holes 15.
  • the coolant is fed into the cooling bores 11 via the coolant channels 10, and expediently, as shown in Figure 2, via a branch 19 between a cooling hole 11 and the adjacent coolant channel 10.
  • FIG 3 also shows that the coolant channels 10 in addition to the cross-sectional planes QE of the metal bolts 12 deeper than the other coolant channels 10 are trained.
  • the arrangement of coolant channels 10 and cooling bores 11 in a copper plate 8 takes place when the copper plate 8 has a sufficient thickness D.
  • coolant channels 10a according to FIG. 4 are worked into the support plate 9a and through the copper plate 8a when fixing the copper plate 8a to the support plate 9a covered with the metal bolt 12.
