Definitions

  • the continuous casting installation comprises a tank for receiving the liquid material to be cast communicating with at least one diestock positioned between said tank and extractor means, said diestock being subjected to the effects of cooling means capable of solidifying said material in a zone of the diestock termed the solidification zone.
  • the diestock is so devised as to be capable of remaining in communication with said tank at the same time as it is shifted longitudinally in relation to other stationary parts of the installation, in the direction of advance of the material being cast, and of then being held immovable in its new position by suitable control means.
  • the present invention relates generally to continuous casting installations, that is to say installations comprising atlease one diestock fed at one end with material in the liquid state which is cooled in this diestock by suitable cooling means to below its solidification temperature and is ultimately extracted at the other end of the diestock in the form of a solid extrusion the section of which matches that of the hold in the diestock, the direction in which the material to be cast is fed being either vertical, horizontal, or oblique, and there being no restrictions as to the nature of the material provided only that it lends itself to the process of continuous casting, as is the case notably with many metals, alloys and plastics.-
  • the invention likewise includes in its scope the extruded sections obtained in such continuous casting installations.
  • the present invention accordingly relates to continuous casting installations comprising a tank for the liquid material to be cast that communicates with at least one diestock positioned between said tank and an extractor device and subjected to cooling means capable of solidifying said material in a zone of said diestock hereinafter referred to as the solidification zone, said diestock being so devised as to be capable of remaining in communication with said tank at the same time as it is shifted longitudinally in relation to other stationary parts of the installation, in the direction of advance of the material being cast, and of then being held immovable in its new position by suitable control means, whereby a shift of said diestock of appropriate amplitude in said direction results, without modification to the values of the solidification parameters, in the diestocks solidification zone being transferred to a region which was theretofore in contact with the
  • the invention includes a number of other features preferably used at the same time, to which more explicit reference will be made hereinafter.
  • the single figure in the accompanying drawing shows diagrammatically in side elevation a continuous casting installation devised in accordance with the present invention.
  • the continuous casting installation shown in the drawing is intended to permit continuous casting of a metallic extruded form such as a round bar 1 made of cuprous alloy.
  • a metallic extruded form such as a round bar 1 made of cuprous alloy.
  • such an installation includes the following component parts:
  • At least one diestock 4 arranged vertically in the exemplary embodiment illustrated and gravity fed with molten metal from the bath 3, whereby the metal consequently travels downwardly through said diestock;
  • a cooling system 5 associated to diestock 4 and based on the circulation of a cooling fluid, for instance;
  • an extractor device 6 mounted downflow of diestock 4 and exerting a pull on round bar 1.
  • diestock 4 is devised in such manner that, at the same time as it remains in communication with liquid bath it be capable of being shifted longitudinally in the direction of advance of the molten material and the bar 1 (Le. downwardly in the specific example herein illustrated), and of then being held immovable in its new position, all other component parts of the installation keeping their positions unchanged.
  • the bottom of tank 2 embodies a passageway therethrough equipped with leaktight means permitting sliding motion of diestock 4, and said diestock is caused to be operable by lockable or irreversible control means preferably of the continuously variable type (as opposed to control means providing preset positions), enabling the diestock to be moved in the required direction (downwardly) and to be held stationary in its new position, said control means consisting for instance of a rack 7 supported on diestock 4 and meshing with a driving pinion 8 adapted to be driven by an irreversible mechanism (such as a worm and skew gear) in such manner that the diestock is automatically restrained in the different successive positions it is made to occupy.
  • lockable or irreversible control means preferably of the continuously variable type (as opposed to control means providing preset positions)
  • said control means consisting for instance of a rack 7 supported on diestock 4 and meshing with a driving pinion 8 adapted to be driven by an irreversible mechanism (such as a worm and skew gear) in such manner that the die
  • the diestock 4 With a continuous casting installation as hereinbet'ore disclosed, the diestock 4 must be in its uppermost position at the start of the casting run and be periodically lowered as the run proceeds whenever the zone of the diestock in which solidification takes place threatens to become damaged (which can be ascertained by examining the surface condition of the extruded sections issuing from the diestock), the diestock being lowered to the extent required to transfer said zone to an ad jacent region further upflow" that is still undamaged.
  • a continuous casting installation devised in the manner described hereinabove offers numerous advantages, outstanding among which are the following:
  • the casting installation comprised only one diestock, it will be manifest that it could include a plurality thereof, which could be moved individually, in groups, or together.
  • a continuous casting device comprising: reservoir means for holding the liquid material to be cast; die means in liquid communication with said reservoir means; cooling means adjacent said die and positioned to solidify liquid material in said die at a solidification zone in said die; extractor means for removing cast material from the die; means for shifting the position of said die from a first position to a second position in a direction longitudinally of the cast material without disturbing the position of said reservoir means and said cooling means and for shifting the position of said die from said second position to a further position in said direction without disturbing the position of said reservoir means and said cooling means; whereby each shift in the position of said die in said direction results, in the absence of any modification of other casting parameters, in a region of the die which was not previously adjacent said solidification zone being transferred to said solidification zone, said region being free of casting deterioration of the type prevalent in a solidification zone, said solidification zone remaining stationary with respect to said reservoir means and to said cooling means.
  • a continuous casting device according to claim 1 further including means for locking said die in said first and further positions 3.
