Definitions

  • ABSTRACT ln an apparatus for the continuous casting of metal strip a casting cavity is formed between a rotating casting drum and an oscillating casting shoe, both of which are supported on a common shaft.
  • the casting belt in such an apparatus wears out relatively quickly and it is difficult to provide a satisfactory seal between the casting belt and the casting wheel.
  • a casting cavity is formed between the convex peripheral surface of a cooled cylindrical casting drum and the concave curved surface of a cooled casting shoe, the cylinder and shoe both being supported by shafts having a common axis which also is the center of the cylindrical surface of the casting drum and of the curved surface of the shoe;
  • the casting shoe is flared outwardly at its substantially vertical inlet section to form a trough to receive molten metal, and it extends around almost one quarter of the casting drum in casting direction to end in a substantially horizontal outlet section.
  • the cast strip therefore leaves the apparatus in a substantially horizontal, straight line, without using a casting belt.
  • one of the surfaces is U-shaped in transverse cross section and the other surface is straight in transverse cross section.
  • that part of the concave surface of the casting shoe which faces the casting drum may have a U-shaped transverse cross section, while the transverse cross section of the outer wall of the drum is straight.
  • the transverse cross section of the outer wall of the drum may be U-shaped, while the transverse cross section ofthat part of the concave surface of the casting shoe which faces the casting drum is straight.
  • the part which has the surface of U-shaped cross section provides a channel located between shoulders which contact the surface of the other part while the surface of the channel is spaced therefrom to form the casting cavity.
  • the shoulders are provided with elastic packing rings which seal the edges of the cavity. Lubrication is provided for all contact areas to reduce wear by friction.
  • the packing rings and the lubrication grooves are located in shoulders formed in the curved wall of the casting shoe.
  • the casting drum In the operation of the apparatus as molten metal is poured into the casting cavity, the casting drum is rotated continuously and the casting shoe is oscillated continuously in timed relation thereto, preferably advancing with the drum at the same speed as the drum, and then being retracted at a greater speed.
  • a temperature equalization chamber to obtain a constant strip temperature may be located between the casting apparatus and the rolling mill.
  • FIG. 1 is a partly sectionalized elevation of the casting apparatus and FIG. 2 is a section on line ll-ll of FIG. 1.
  • a cylindrical casting drum 3 is mounted for rotation on shafts 2 joumalled in a frame 1.
  • the drum is driven by a motor 6 through gears 4, 5.
  • a casting shoe 8 is provided with side plates 7 which are located between he frame 1 and the ends of the casting drum 3 and are pivotally supported on the drum shafts 2.
  • the shoe which forms a casting cavity 9 with the drum, may be oscillated by any suitable means, as by a hydraulic cylinder 10, or an eccentric or the like.
  • the cavity 9 is formed between theconvex cylindrical wall 11 of the drum 3 and the concave curved wall 12 of the casting shoe 8. Coolants flow through channels 14 in the drum and through channels 15 in the casting shoe.
  • the side edges of the casting cavity 9 are sealed by shoulders 13 and packing rings 16 which are located on the outside of the shoulders 13, and thereby reduce friction between the wall 11 and the shoulders 13.
  • the shoulders 13 also have lubrication grooves 17 which are located between the packing rings 16 and the cavity 9 and which help to prevent the escape of metal from the cavity.
  • liquid metal pours from the ladle 19 into the tundish 18, which rests on frame 1.
  • An exit opening 18 of the tundish is located vertically above the flared inlet section 20 of the casting shoe.
  • the liquid metal is solidified through contact with the cooled walls 11 and 12 and the shoulders 13 and forms a strip 21, which leaves the casting apparatus in a substantially horizontal direction along a roller table 22.
  • the strip may be conducted through a temperature equalization chamber 23 and then through a rolling stand 24 and may thereafter be coiled on a coiler 25.
  • Apparatus for the continuous casting of metal strip comprising a casting drum having a convex casting surface, a casting shoe having a concave curved casting surface, the convex casting surface of the casting drum and the concave casting surface of the casting shoe having a common center of curvature and being spaced to provide a casting cavity therebetween, the casting drum being mounted for rotation and the casting shoe being mounted for oscillation on a common axis which is the center of curvature of said casting surfaces.
  • the apparatus of claim 1 including means for rotating said casting drum and means for oscillating said casting shoe.
