Definitions

  • An inlet funnel is disposed adjacent the mold and is adapted to feed liquid metal into the mold.
  • the lower part of the mold extends to a lower part of the funnel.
  • the mold has cooling conduits extending therethrough.
  • a rotatable metal feeding roll is disposed above the lower part of the mold and has a plurality of cooling conduits. The surface of the metal feeding roll is formed complementary to the profile of the metal strip to be cast.
  • the present invention relates to a continuous strip-casting apparatus for casting of metal.
  • the known strip-casting apparatus is operated generally by means of vertically disposed molds.
  • such arrangement requires often considerable structural heights, which require corresponding tall buildings. In order to avoid these structural heights, such arrangements have already been built into deep pits.
  • It is still another object of the present invention to provide a strip-casting apparatus which includes a brush arranged on the upper part of the periphery of the metal feeding roller adapted for the cleaning of the surface of the metal feeding roller and which provides simultaneously a spraying device for the application of the mold lubricant, while a feed conduit for the mold conduit is arranged in the advanced lower part of the mold.
  • FIGURE 1 is a longitudinal sectional view of a horizontal strip-casting apparatus according to the present invention along the lines 11 of FIG. 2;
  • FIG. 2 is a top plan view of the apparatus disclosed in FIG. 1;
  • FIG. 3 is a section along the lines 3-3 of FIG. 1;
  • FIG. 4 is a fragmentary section along the lines 4--4 of FIG. 1.
  • the strip-casting apparatus comprises an inlet funnel 2 over which the liquid metal 1 is fed by means of a ladle (not shown) or by means of a teeming furnace in a free fall over a pouring device or over a direct connection (not shown) into the apparatus, which liquid metal 1 is covered by a protective mass 3, in order to prevent oxidation.
  • a skimmer 4 prevents that slag or oxides enter in an unwarranted manner the liquid metal 1.
  • the mold consisting of two parts 5 and 6, which are rigidly connected together and which perform a reciprocating movement during the casting, is set-off in its upper part 5 at the entrance point for the liquid metal 1 corresponding to the profile of the metal feeding roll 10 over the upper part 5 of the mold, while the lower part 6 constituting the inlet part, is advanced to the inlet funnel 2.
  • the inlet funnel 2, as well as the metal feeding roll 10, perform the reciprocating movements of the mold during the casting by using any conventional means therefor.
  • the upper part 5 of the mold is, however, set-off along the center line of the profile, in case of the use of round cross-sections.
  • the metal feeding roll 10, equipped with cooling tubes 9, is arranged in front of the set-off upper part 5 of the mold, which metal feeding roll 10 is formed according to the profile 7 of the metal strip 8.
  • the metal feeding roll 10 engages at its lower engaging point the surface of the metal strip 8, rotates in the direction of movement of the latter and drives forwardly the latter in this manner.
  • the metal feeding roll 10 is sealed off toward the liquid metal 1 in the inlet funnel 2, as well as: in the advanced lower part 6 of the mold by means of a packing 11 made of a refractory, metal-repelling plastic mass.
  • the mold lubricant required for the sliding of the metal strip 8 in the mold, is fed for the upper part of the metal strip 8 by means of a spraying device 12 to the metal feeding roll 10, which is cleaned by a rotating brush 13, and reaches with the latter the surface of the metal strip 8.
  • the mold lubricant for the lower part of the metal strip 8 is fed into the mold by means of a feeding conduit '14 terminating in the advanced part 6 of the mold.
  • a lifter 15 is provided on the set-off edge of the upper part 5 of the mold.
  • the mold which is cooled by a coolant fed through conduits 16, is secured to a lifting slide 18 mounted in the machine frame 17, which lifting slide 18 is driven by a controllable drive 19 by means of the drive shaft 20 and the pushand connecting rods 21.
  • the metal strip 8 which is on the outside already completely solidified, moves from the indirect cooling zone in the mold into a zone 22 providing direct cooling by means of spraying nozzles 23, by which the coolant is sprayed on, where the metal strip 8 is completely solidified and is maintained by non-driven support rolls 24 still in horizontal position.
  • Transport rolls 25, which have the same rotational speed as the metal feeding roll 10, caused by a common drive 26 or also by individual, yet common electrically controlled drives, move the metal strip 8 in dependency upon the profile 7 of the metal strip 8, the type of metal cast and the casting speed from the mold to the further working stations.
  • the drive of the metal feeding roll 10 takes place over the drive shaft 27 and any suitable transmission 28.
  • a strip-casting apparatus for casting of metals comprising a stationary frame,
  • a substantially horizontal reciprocable continuous mold having an upper part and a lower part, said upper part being shorter than said lower part,
  • said lower part and said upper part of said mold having a form complementary to the profile of the metalstrip to be cast
  • an inlet funnel disposed adjacent said mold and adapted to feed liquid metal into said mold
  • said mold having cooling conduits extending therethrough, a rotatable metal feeding roll disposed between said upper mold part and said inlet formed above said lower part of said mold,
  • said metal feeding roll having a plurality of cooling conduits
  • the surface of said metal feeding roll being formed complementary to the profile of said metal strip to be cast, and means for performing a reciprocating movement of said mold, funnel and feeding roll.
  • the strip-casting apparatus as set forth in claim 1, which includes spraying means disposed adjacent said metal feeding roll adapted for applying a lubricant to the outer surface of said metal feeding roll. 5.
  • the strip-casting apparatus as set forth in claim 4, which includes feed means connected to said lower part of said mold for applying a lubricant thereto. 6.
  • the strip-casting apparatus as set forth in claim 1, which includes brush means disposed at the upper part of the periphery of said metal feeding roll adapted for cleaning the surface of said metal feeding roll. 7.
  • the strip-casting apparatus as set forth in claim 1, which includes lifting means disposed at the set-off edge of said upper part of said mold between said strip and said metal feeding roll, said lifting means having a form complementary to the profile of said metal strip to be cast.
  • the strip-casting apparatus as set forth in claim 1, which comprises direct cooling means for said metal strip to be cast disposed behind said mold and including spray nozzles for a coolant surrounding said metal strip and at least one pair of supporting roll means engaging said metal strip.
  • the strip-casting apparatus as set forth in claim 8, which includes at least a pair of transport rolls behind said direct cooling means for discharging said strip from said apparatus. 10.
  • the strip-casting apparatus as set forth in claim 9, which comprises common drive means for rotating said metal feeding roll and said transport rolls at substantially synchronous speeds.
  • said drive means includes a drive for said transport rolls and transmission means between said drive and said metal feeding roll, for rotating the latter.
