Definitions

  • ABSTRACT The disclosure relates to a process for continuous continuous casting in which melts of different chemical compositions are successively cast into a water-cooled mould to form a continuous bar.
  • the invention relates to a process for continuous continuous casting of hot liquid metals, in which melts of different chemical compositions are successively cast into a water-cooled mould to form a continuous bar which is drawn out of the mould and further cooled.
  • the invention is aimed at avoiding these disadvantages, i.e., at furnishing the prerequisites enabling melts of different composition to be cast to a continuous bar without loss; in a process of the kind defined in the introduction the invention resides in that on termination of casting a melt with the one composition (A), a metallic body, preferably a plate adapted to the cross section of the mould, is inserted into the mould and welds with the melt of the composition (A), whereupon casting is continued with a melt of another composition (B) which, in its turn, welds with the metallic body.
  • a device for carrying out the process according to the invention is characterized by a metallic body, preferably a plate, having hook or rail-shaped projections on both faces whcih body may be inserted into the hollow space of a continuous casting mould and temporarily supported by means of meltable brackets on the upper margin of the mould.
  • Numeral l deontes a water-cooled continuous casting mould from which the continuous cast bar 2 is drawn out; said bar is further cooled in a secondary cooling means, not shown, and finally it is severed into several pieces by a separation means, likewise not shown.
  • the cast bar 2 has a solidified bar shell 3 and a liquid core 4.
  • the casting level i.e., the surface of the hot liquid metal in the mould, is denoted with 5.
  • the casting level 5 is covered with a casting powder which protects the steel against oxidation by air.
  • the casting powder floating on the casting level 5 is removed when the casting of melt A is terminated, and a steel plate 6 having a thickness of about 15 to 50 mm is inserted into the hollow space of the mould.
  • the cross section of the steel plate is adjusted to the cross section of the mould 1 but somewhat smaller than the latter so that an annular gap 7 of several millimeters width is present between the mould wall and the steel plate.
  • the steel plate 6 may immerse into the liquid core 4 and welds with the liquid core on the whole surface so that a solid connection with the cast bar 2 is established.
  • the plate 6 may be brought to lie on the bar shell 3 and, additionally, be fixed for a short period in this position.
  • the holding brackets 8 arranged on the plate 6 serve this purpose; they melt off when casting when melt B is continued. This melt B welds also with the steel plate 6; it is not possible that the melts mix.
  • the thickness and the formation of the steel plate 6 as well as its chemical composition depend on the casting conditions, the
  • a process for continuously casting successive casting melts of different compositions wherein each melt is cast through a water cooled mould to form a continuous cast bar, the bar is drawn out of the mould and cooled, and a continuous strand of intimately connected sections is produced, comprising the steps of casting a melt of a first composition through the mould to form a continuous cast bar,
  • the metallic body having substantially the same size and shape as the cross section of the mould
