Definitions

  • charge casting to manufacture a product such as a metal billet or a metal plate: a liquid metal is brought in particular by gravity in an ingot mold, arranged for example in the lower part of the mold, cooled externally and provided with a movable bottom. During its stay in the ingot mold, the metal solidifies and is evacuated using the movable bottom while the riser is replenished, so as to maintain an almost constant level of liquid metal there.
  • a person skilled in the art is familiar with semi-continuous vertical casting or “vertical casting” or semi-continuous horizontal casting or “horizontal casting”. These two names are special cases of laden casting.
  • the mold includes a graphite part mounted internally in the support so as to be in contact with the liquid metal during its solidification.
  • the essential function of the transition ring in addition to ensuring the mechanical connection between the ingot mold and the enhancer, is to seal the mold in the junction zone between the ingot mold and the enhancer.
  • This problem is particularly essential in view of the very high fluidity at casting temperature of certain aluminum alloys such as, for example, aluminum-silicon alloys.
  • this technique induces a significant metallostatic pressure in this junction zone.
  • the transition ring is held in place by a single clamping piece which applies an axial force to it during casting, this force resulting from a force transmitted to this clamping piece by numerous clamping systems of the bolt type distributed around the main direction.
  • the number of such systems is multiple, in order to guarantee the application of a predetermined clamping force, uniform on the periphery and constant with regard to the temperature variations undergone all the more so for large-scale ingot molds.
  • the present invention aims to solve all or part of the drawbacks listed above.
  • the holding mechanism comprises a locking ring capable of transmitting said holding force to the clamping ring, and biasing means permanently urging the locking ring in the main direction towards the ring clamping according to a compression force such that in the inactive state of the axial load shedding mechanism, the locking ring urged by the biasing means according to said compression force exerts said holding force on the clamping ring.
  • the locking ring and the clamping ring are integral with one another, in particular by being formed in a single piece.
  • the locking ring is a piece independent of the clamping ring and in its active state, the axial load shedding mechanism temporarily stresses the locking ring in the main direction in a direction opposite to the compression force. applied by the biasing means in such a way as to suppress the support of the locking ring on the clamping ring in the main direction, to allow said removal of the clamping ring from the mold.
  • the clamping ring and the locking ring can cooperate together according to a locking / unlocking system.
  • the locking / unlocking system is a bayonet system, the relative angular variation between the two rings around the main direction making it possible to vary between a first angular configuration in which the clamping ring can pass through the ring locking in the main direction in a direction opposite to the transition ring and a second angular configuration in which the clamping ring is blocked by the locking ring in the main direction in the opposite direction to the transition ring.
  • the locking ring is integral with a piston and the axial load shedding mechanism comprises on the one hand a chamber delimited between said piston and the support of the mold, on the other hand a management system allowing to vary the pressure in the chamber.
  • the management system may comprise on the one hand a device for controlled supply of the chamber with a fluid such as air or oil, having a pressure allowing the force to be applied to the piston greater than the compressive force applied to the locking ring by the biasing means and on the other hand a controlled exhaust device for said fluid outside the chamber.
  • a fluid such as air or oil
  • the biasing means comprise a plurality of elastic compression devices angularly distributed around the main direction, each elastic compression device being interposed between the support of the mold and the piston.

  • the clamping ring is an independent part of the transition ring.
  • the invention essentially relates to a tool allowing the manufacture of a metal product by casting under load, this tool being partially shown in the figures.
  • charge casting suitable for manufacturing a metal product such as a metal billet or a metal plate.
  • the nature of the metal can vary depending on the applications. It can preferably be aluminum alloys.
  • a “billet” is a cylindrical piece of circular section, then intended to be cut into slices along its length, each slice can then be used in a subsequent extrusion operation via a die.
  • the section of the billet depends on the section of the ingot mold in a plane perpendicular to the axial direction.
  • the mold 10 can also include a graphite part mounted in the integrated cooling support to be in contact with the liquid metal.
  • the transition ring 11 then comes to press on the graphite part of the ingot mold 10 in the main direction X and provides the seal with respect thereto.
  • the main direction X is oriented substantially parallel to the main axis of the mold.
  • the main direction X is oriented substantially vertically, allowing in this case a gravitational flow of the liquid metal to pass from the raising to the ingot mold 10, the movable bottom then also moving in the direction of gravity.
  • the main direction X is oriented substantially horizontally, allowing in this case a gravitational flow of the liquid metal to pass from the raising to the mold 10, the movable bottom then moving on a horizontal axis.
  • the means allowing the integrated cooling of the support of the mold 10 can be any, such as for example internal conduits in which a cooling liquid such as water circulates.
  • the extension is arranged in the upper part of the mold and the ingot mold 10 is located in the lower part of the mold.
  • the movable bottom is located below the ingot mold 10, on the side opposite the extension and the transition ring 11. The movable bottom moves vertically downwards as the solidification of the liquid metal takes place in the ingot mold 10.
  • the movable base can be controlled, in particular according to a controlled speed and stroke.
  • the tool comprises a clamping ring 12 capable of transmitting a clamping force F1 to the transition ring 11, this clamping force F1 being oriented towards the mold 10 in the main direction X.
  • the tool also includes a holding mechanism ensuring positive locking of the clamping ring 12 bearing against the transition ring 11 in order to immobilize the transition ring 11.
  • the holding mechanism is configured to so as to be able to exert a holding force F2 on the clamping ring 12 directed towards the transition ring 11 in the main direction X, the positive blocking resulting precisely from the application of this holding force F2 on the clamping ring 12 which has the effect of applying the clamping force F1 on the transition ring 11.
  • the holding force F2 is applied automatically to the clamping ring 12 by the holding mechanism as soon as the axial load shedding mechanism is in its inactive state, while it is no longer applied in the case where the axial load shedding mechanism is temporarily and voluntarily placed in its active state.
  • the clamping ring 12 is an independent part of the transition ring 11.
  • the clamping ring 12 is notably configured so as to come to bear against the transition ring 11 in the main direction X in a direction opposite to pressing against the ingot mold 10.
  • the transmission of the clamping force F1 from the clamping ring 12 to the transition ring 11 takes place at this support zone between the two rings 11, 12, for example in the form of an external shoulder formed at the periphery of the transition ring 11.
  • clamping ring 12 and the transition ring 11 are integral with one another.
  • the holding mechanism comprises a locking ring 13 capable of transmitting the holding force F2 to the clamping ring 12 and biasing means 14 permanently stressing the locking ring 13 in the main direction X in the direction of the clamping ring 12 according to a compression force F3 such that in the inactive state of the axial load shedding mechanism, the locking ring 13 urged by the means of stress 14 following this compression force F3 exerts the holding force F2 on the clamping ring 12.

  • the figures 3 and 4 represent this situation, unlike figures 1 and 2 where the support of the locking ring 13 is in progress on the clamping ring 12.
  • the temporary stressing of the locking ring 13 by the load shedding mechanism here means that the axial load shedding mechanism transmits a temporary force to the locking ring 13 ( figure 3 ), this force having a component in the main direction X having an intensity greater than the intensity of the compression force F3 applied permanently by the biasing means 14 to the locking ring 13.
  • the clamping ring 12 and the locking ring 13 cooperate together by a locking / unlocking system configured so that in the inactive state of the load shedding mechanism, the locking / unlocking system cannot be activated towards a unlocking state of the ring 12 and is, on the contrary, blocked in a state of locking of the rings 12, 13.
  • the load shedding mechanism is active, the passage of the locking / unlocking system from the locking state to the unlocking state is on the contrary possible.
  • the locking / unlocking system is a bayonet system.
  • the relative angular variation between the two rings 12, 13 around the main direction X makes it possible to vary between a first angular configuration ( figure 4 ) in which the clamping ring 12 can pass through the locking ring 13 in the main direction X in a direction opposite to the transition ring 11 and a second angular configuration (situation of figures 1 , 2 and 3 ) in which the clamping ring 12 is locked by the locking ring 13 in the main direction X in the direction opposite to the transition ring 11.

  • the lugs 16 are here angularly distributed around the main direction X by being arranged, in particular projecting, on an inner edge of the clamping ring 12.
  • the transition from the first angular configuration to the second angular configuration and vice versa is possible only when the axial load shedding mechanism occupies its active state. It is however inhibited as long as the axial load shedding mechanism occupies its inactive state, also participating in the positive blocking function conferred by the holding mechanism.
  • the transition from the first angular configuration to the second angular configuration and vice versa is obtained by a rotational movement ⁇ of the clamping ring 12 relative to the mold around the main direction X over a predetermined angular travel, the locking ring 13 remaining fixed relative to the mold during this movement ⁇ of the clamping ring 12.
