Patent number: 5232046Abstract: Continuous casting apparatus comprising a tundish having a pouring nozzle communicating with a closed, pressurized pouring box which has an outlet corresponding to the inlet of a mold such that the entry conditions of liquid metal into the mold are not adversely affected by the flow of liquid metal into the mold thereby providing a uniform skin of solid metal about a liquid metal core as the cast product is withdrawn from the mold.Type: GrantFiled: December 10, 1991Date of Patent: August 3, 1993Assignee: Mesta InternationalInventors: Frank Gallucci, Joseph Pietryka

Patent number: 4706733Abstract: To reduce the cost of the mold, the mold of a continuous casting machine has no frame and the machine comprises an oscillating table constituted by a rectangular frame having large sides and small sides defining an opening, a mold carried by the oscillating table in this opening and comprised of two opposing large plates and two opposing small plates held tightly between the large plates. Supports for the small plates are integral with devices for adjusting the position of the small plates and jacks are provided for exerting a pressing force upon the large plates for pressing them tightly against the small plates. The large plates, the position adjusting devices and the jacks for exerting the pressing force are mounted on the oscillating table.Type: GrantFiled: January 15, 1987Date of Patent: November 17, 1987Assignee: Fives-Cail BabcockInventors: Joseph Pietryka, Joel Cazaux

Patent number: 4524818Abstract: To enable a segment of a cluster of bottom and top guide rolls to be readily replaced in a curved guide rack of a continuous casting installation, two fixed guide rails extend generally radially with respect to the curved guide rack at the two opposite sides of the guide roll support, rollers at opposite sides of the support engaging the guide rails for movement therealong, each guide rail including at least one portion inclined in relation to the generally radial direction of the guide rail and so disposed that, when the support is displaced along the guide rails, the support is pivoted into a skewed position which permits the support to pass between the two outer top guide rolls of two like segments adjacent thereto.Type: GrantFiled: June 20, 1983Date of Patent: June 25, 1985Assignee: Fives-Cail BabcockInventor: Joseph Pietryka

Patent number: 4382462Abstract: The invention is an apparatus for removing a dummy bar from a casting line and reintroducing the dummy bar into the mold. The apparatus comprises a handling system for moving a basket from an end station where the dummy bar is separated from a continuous casting to a position above the mold of the casting installation. The system includes a lifting frame capable of holding the basket, a raising device having one end attached to the lifting frame for vertically raising the lifting frame, a travel frame supporting and end of a raising device opposite to the one end, the travel frame having vertical runways capable of receiving and guiding the raised lifting frame, and a horizontal pathway supporting the travel frame for movement to and from the position above the mold.Type: GrantFiled: November 17, 1980Date of Patent: May 10, 1983Assignee: Fives-Cail BabcockInventors: Joseph Pietryka, Joel Cazaux, Andre Guyot

Patent number: 4323107Abstract: An installation for continuously casting steel billets comprises a support structure and a guiding roll-rack for the cast billets receiving molten steel from an oscillatory mold and comprising an upper and lower section each having a frame. The upper section and the mold constitute a demountable and replaceable unit. The upper section is supported on the top of the lower section and carries a support for guiding the mold for oscillation. The lower section is mounted on the support structure and carries a mechanism for oscillating the mold. This mechanism comprises an arm mounted for pivoting on the top of the lower guiding device section frame, an actuating rod connecting the arm to the mold for oscillating the mold is response to the pivoting of the arm, and respective pivots connecting the actuating rod to the arm and to the mold, one of the pivots being readily detachable.Type: GrantFiled: September 17, 1979Date of Patent: April 6, 1982Assignee: Fives-Cail BabcockInventor: Joseph Pietryka

Patent number: 4086955Abstract: A dummy or starter bar head used in the continuous casting of molten metal has an elongated cavity along its upper small face whose cross section increases inwardly from the small face. This cavity is formed partly in the head and partly in an insert removably mounted on the head, the plane of separation between the portion of the cavity defined by the head and that defined by the insert being so disposed that cast solidified metal formed in the cavity may be lifted out of the portion of the cavity after the insert has been removed.Type: GrantFiled: December 15, 1976Date of Patent: May 2, 1978Assignee: Fives-Cail BabcockInventor: Joseph Pietryka

Patent number: 4022267Abstract: The curved roll rack receiving partly solidified metal from the mold in an operating continuous casting installation and defining a path guiding the stream of metal from a substantially vertical into a substantially horizontal direction of movement has two sections consecutively arranged along the path. Pivots secure respective, contiguously adjacent, terminal portions of the sections to a common support for angular movement about horizontal axes while bearings interposed between the remote terminal portions of the two sections permit sliding movement of the remote portions on the support in planes parallel to the associated horizontal axes when the rack thermally expands and contracts.Type: GrantFiled: June 28, 1976Date of Patent: May 10, 1977Assignee: Fives-Cail BabcockInventor: Joseph Pietryka

Patent number: 3986547Abstract: An ingot mold is detachably fixed on an oscillating chassis. A first tubing supplies a fluid cooling medium to the mold and a second tubing is mounted on the oscillating chassis for feeding the cooling medium to the first tubing and for removing it therefrom. Means for interconnecting the first and second tubings comprises a first mount independent of the mold, to which the first tubing is attached, a second mount carried by, but independent of, the chassis, to which the second tubing is attached, and means for attaching the two superposed mounts to each other independently of the means fixing the mold on the chassis.Type: GrantFiled: January 3, 1975Date of Patent: October 19, 1976Assignee: Fives-Cail BabcockInventor: Joseph Pietryka
