Definitions

  • a conventional continuous-casting mold is a doublewalled open-ended sleeve.
  • the inner wall or liner usually is formed of copper to furnish maximum thermal conductivity, and the outer wall or backing is formed of steel plates to furnish mechanical strength.
  • Liquid metal is poured into the top of the mold and a partially solidified casting emerges continuously from the bottom. Channels are formed between the backing and liner through which water circulates to cool the liner and assist in solidifying the casting.
  • the channels may be machined into either the copper liner or steel backing, but preferably into the latter to conserve copper which is more costly. It is of course necessary to fasten the backing plates and liner together.
  • An object of my invention is to provide an improved continuous-casting mold which enables me to diminish the wall thickness of the copper liner, thus affording a better stress pattern and using less copper.
  • a more specific object is to provide an improved mold in which I weld the studs to the copper liner, either through the use of intermediate strips or directly.
  • FIG. 1 is a. simplified exploded perspective view of one form of mold constructed in accordance with my invention
  • FIG. 2 is a vertical section through the double-wall of the mold showing a modification
  • FIG. 3 is a section similar to FIG. 2, but showing another modification and FIG. 4 is a horizontal section through the double-wall of the mold showing a further modification.
  • FIG. 1 shows a continuous-casting mold which includes a copper inner wall or liner l and an outer wall or backing formed of steel side plates 12, end plates 13 and corner bars 14.
  • the liner illustrated is of one-piece welded construction and has a relatively thin wall, preferably about inch thick.
  • a plurality of vertical channels 15 are machined in the inside faces of the side and end plates 12 and 13, leaving ribs 16 between channels.
  • the channels serve as passages for circulating water to cool the liner.
  • the lower and upper ends of the channels have water inlets and outlets, which are arranged in the usual fashion but are not shown since they are not involved in the present invention.
  • a plurality of shallow vertical channels 17 are machined in the outside faces of liner at locations opposite ribs 16. I weld stainless steel strips 18 in these channels.
  • the strips preferably are about 3/16 inch thick and of a maximum width of about 1 inch, and in this embodiment are continuous from the top to the bottom of the liner.
  • the side and end plates 12 and 13 have openings 20 through their ribs 16 to receive the studs. Nuts are threadedly engaged with the ends of the studs outside the plates to hold the parts assembled. I attach the corner bars 14 with threaded connectors (not shown) to afford handling and torsional rigidity to the assembled mold.
  • FIG. 2 shows a modification in which the stainless steel strips are in discontinuous sections 23 with gaps 24 therebetween.
  • the nuts on the studs are countersunk in the outside of the plates.
  • the same countersunk arrangement also can be used with the embodiment shown in FIG. 1.
  • the embodiment of FIG. 2 is similar to that of FIG. 1; hence I have not repeated the description.
  • FIG. 3 shows another modification in which I weld studs 26 directly to the copper liner 27.
  • FIG. 4 shows another modification in which I apply the principles of my invention to a four-piece copper liner.
  • the liner includes end members 29 which abut the inner faces of side members 30. This construction enables the liner to be adjusted to cast different sizes of product, as known in the art.
  • a continuous-casting mold which includes a relatively thin-walled copper liner of a thickness of about inch, steel backing plates outside said liner and having vertical channels in their inside faces for circulating water and ribs between channels, and means fastening said plates to said liner, the improvement in which s'aidfastening means-includes stainless steel strips, a plurality of studs welded to each of said strips, and nuts threadedly engaging said studs, said liner having vertical channels in its outside face opposite said ribs, said strips being welded in said second-named channels, said studs extending through openings in said ribs, said nuts being located outside said plates.
  • a mold as defined in claim 1 in which said strips are in sections with gaps between sections.
