Patent number: 10814378Abstract: 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.Type: GrantFiled: January 27, 2017Date of Patent: October 27, 2020Assignee: CONSTELLIUM ISSOIREInventors: Bernard Valentin, Arnaud Ballu, Soizic Blais

Patent number: 10532398Abstract: 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.Type: GrantFiled: March 8, 2017Date of Patent: January 14, 2020Assignee: CONSTELLIUM ISSOIREInventors: Arnaud Ballu, Bernard Valentin, Soizic Blais
