Definitions

  • the molten metal is supplied continuously to a cooled vertical open-ended mold, from which the metal which is at least partly solidified to form a solid marginal zone is withdrawn more or less continuously and is passed through a cooling zone wherein solidification of the metal continues at least to an extent such as to allow the casting to be gripped and advanced by means of one or more pairs of driven rolls without the casting being undesirably distorted or deformed by the action of the roll pressure required to achieve the friction necessary to advance the casting.
  • the casting which leaves the mold in a more or less vertical direction is often bent to a horizontal or substantially horizontal direction by means of a pressure roll or other bending means, whereupon the casting is straightened before it is cut to desired lengths.
  • the greater operational reliability resides in the circumstance that failure to cut the continuous casting and operational disturbances in the means for advancing the casting after it has left the mold do not affect the casting process as such, since it is easier to provide sufficient space for advancing an uncut casting than in the case when the casting moves vertically towards a confining floor.
  • the present invention relates to a method of bending the casting which leaves the mold in a substantially vertical direction, to a substantially horizontal direction with the smallest possible local stresses in the casting and with the smallest possible need of space to carry out the bending operation.
  • the method of this invention comprises carrying out the bending of the casting to the desired substantially horizontal direction progressively or stepwise.
  • the elongation to which the material in the casting is subjected in the bending method used hitherto can be reduced considerably, in that the bending is caused to take place progressively or is increased step by step as the temperature of the casting falls and solidification proceeds.
  • the casting may obtain a paraboliform bending configuration during passage through the bending means.
  • companion rolls E and E bend the casting about fulcrum roll B through are 2 having approximately the radius R
  • companion rolls E and E bend the casting about fulcrum roll B through are 2 having approximately the radius R
  • rolls A and B are opposition rolls which retain the casting against the fulcrum roll B
  • Roll F next bends the casting through are 3 having substantially the radius R roll B acting as the opposing roll to maintain the casting against fulcrum roll E
  • roll F further bends the casting about the fulcrum F through the arc 4 having approximately the radius R roll E acting as an opposing roll to hold the casting against the fulcrum roll F and roll G being merely a guide roll.
  • C -C are thecenters of radii R R respectively.
  • the method of bending a casting which leaves a continuous casting mold, from a substantially vertical direction to a substantially horizontal direction which comprises performing the bending in a plurality of steps, the amount 3 4 of bending increasing as the temperature of the casting 2,698,467 1/ 1955 Tarquinee et a1 22200.1 falls and solidification thereof proceeds. 2,947,075 8/1960 Schneckenburger et a1.
