In order to obtain a high economic viability and improved machining parameters when the strips are rolled, the slab (3) is milled as a first mechanical machining step after the slab (3) is deviated in the horizontal direction (H). The slab (3) is cast with a thickness (d) of at least 50 mm and the slab (3) is cast with a mass flow, which is the product of the casting speed and the slab thickness (v×d), of at least 350 m/min×mm.Type: ApplicationFiled: May 23, 2007Publication date: July 2, 2009Inventors: Jürgen Seidel, Peter Sudau

Patent number: 7475716Abstract: A mold handling system for carrying and transporting sand molds comprises a mold handling conveyor with multiple mold exits to provide different outputs for the sand molds. The mold handling system may include flags which can be used to mark selected molds to segregate the sand molds into different groups. A control system responds to flag sensors and tracks the molds to selectively control output of sand molds through the mold exits. Methods of handling sand molds using a mold handling system are also disclosed.Type: GrantFiled: October 29, 2004Date of Patent: January 13, 2009Assignee: Hunter Automated Machinery CorporationInventors: William A. Hunter, William G. Hunter

Publication number: 20080169080Abstract: A casting mould for manufacturing a cast part from a metal melt includes a mould cavity for reproducing a cast part and comprising an inlet for pouring metal melt into the mould cavity and also to a device and a process for casting metal melts of this type. The casting mould provides further optimized casting results even under hard practical operating conditions. In addition, the use or application of the device according to the invention and the process minimizes the risk of jamming during casting. This is achieved in that the casting mould has at least one compensation chamber which is linked to the mould cavity via a channel and comprises at least one portion which is arranged above the maximum filling level (Fmax) of the casting mould during solidification of the metal melt.Type: ApplicationFiled: February 22, 2006Publication date: July 17, 2008Inventors: Klaus Lellig, Michael Stolz

Publication number: 20080156451Abstract: A die casting process using pattern recognition techniques to identify those die castings manufactured under conditions likely to produce a die casting which would subsequently prove unacceptable for use. By promptly identifying such die castings, they may be discarded before being shipped to a remote facility for further processing. As a result, the rejection rate of die castings at the remote facility may be reduced and the raw materials used to form the discarded die castings may be more readily recycled.Type: ApplicationFiled: March 14, 2008Publication date: July 3, 2008Applicant: L&P PROPERTY MANAGEMENT COMPANYInventors: Arnie FULTON, Yan ZHU, Michael BOMAR

Publication number: 20080112878Abstract: A chalcogenide compound synthesis method includes homogeneously mixing solid particles and, during the mixing, imparting kinetic energy to the particle mixture, heating the particle mixture, alloying the elements, and forming alloyed particles containing the compound. Another chalcogenide compound synthesis method includes, under an inert atmosphere, melting the particle mixture in a heating vessel, removing the melt from the heating vessel, placing the melt in a quenching vessel, and solidifying the melt. The solidified melt is reduced to alloyed particles containing the compound. An alloy casting apparatus includes an enclosure, a heating vessel, a flow controller, a collection pan and an actively cooled quench plate. The heating vessel has a bottom-pouring orifice and a pour actuator. The flow controller operates the pour actuator from outside the enclosure. The quench plate is positioned above a bottom of the collection pan and below the bottom-pouring orifice.Type: ApplicationFiled: November 9, 2006Publication date: May 15, 2008Inventors: Janine K. Kardokus, Michael R. Pinter, Ravi Rastogi, Diana L. Morales, Michael D. Bayton, Norman L. Sand, Bryan E. Powers

Patent number: 7036558Abstract: An evaluation method in which a capacitive sensor is placed in a region of a container, into which a granular material is fed so as to contact the sensor, and the variation in the impedance of the sensor caused by feeding in the material is evaluated. The method is particularly useful for evaluating the compactness of sand in a formwork for making metal castings. The evaluation system includes a sensor defined by plates sensitive to the variation in the dielectric; and a conditioning and control circuit for indicating the variation in the capacitance of the plates, or more generally the total impedance of the system, when the granular material is fed into the container. In one embodiment, the plates of the sensor are defined by two combs made of conducting material, having two numbers of interlacing segments, and located on a rigid or flexible support.Type: GrantFiled: February 3, 2003Date of Patent: May 2, 2006Assignee: C.R.F.
