Abstract: A tooling for producing a metal product by feed casting, including a mold having a preheater, an ingot mold (10), a movable bottom that moves in a main direction X and a transition ring interposed between the preheater and the ingot mold (10). The tooling has a clamping ring (12) transmitting a clamping force (F1) to the transition ring (11) oriented towards the ingot mold (10), a holding mechanism that positively locks the clamping ring (12), and an axial relief mechanism configured to vary between an inactive state in which the holding mechanism exerts a holding force (F2) on the clamping ring (12) such that the clamping ring (12) exerts the clamping force (F1) on the transition ring (11) and an active state in which the axial relief mechanism resists the action applied by the holding mechanism on the clamping ring in the inactive state.

Abstract: A system for controlling the progress of the manufacture of at least one product by vertical semi-continuous direct chill casting, in particular from aluminium alloy, in a fixed mold, the control system includes a dummy bottom configured to form a movable lower bottom of the fixed mold and to carry the product during casting; a weighing cell, on which the dummy bottom is arranged to rest, the weighing cell being configured to take measurements representative of the mass of the product carried by the dummy bottom during casting; and a support of the dummy bottom, to which the weighing cell is linked, configured to lower the false bottom relative to the fixed mold, substantially in a vertical direction, during casting; and a processing unit connected to each weighing cell, and configured to process the measurements, and calculate the variation in the mass of the product over time.

Abstract: An enclosure having a sealing device, for a casting installation, having a first body and a second body that is removably joined to the first body along a bearing axis, the first and second bodies together delimiting an internal chamber. The sealing device comprises: at least one compression member, at least one seal having a lateral contact face extending substantially parallel to the bearing axis; the compression member and the seal being arranged with respect to one another such that the compression member is in contact with the lateral contact face of the seal and exerts a compression force thereon that is oriented orthogonally to the bearing axis.

Abstract: The invention relates to a method for manufacturing an aluminum alloy product including the steps of: creating a bath of liquid metal in an aluminum-copper-lithium alloy, casting said alloy by vertical semi-continuous casting so as to obtain a plate with thickness T and width W such that, during solidification, the hydrogen content of said liquid metal bath (1) is lower than 0.4 ml/100 g, the oxygen content above the liquid surface (14, 15) is less than 0.5% by volume.
