A non-contact heating apparatus uses a series of rotating magnets to heat, levitate, and/or move metal articles therethrough. A first series of rotating magnets heats the metal article to a desired temperature. A second series of rotating magnets levitates the metal article within the heating apparatus and maintains desired tension in the metal article, including urging the metal article through the heating apparatus. The heating apparatus can extend sufficiently far to soak the metal article at the desired temperature for a desired duration. The rotating magnets can be positioned outside of an electrically non-conductive, heat resistant chamber filled with an inert or mildly reactive gas, through which the metal article passes in the heating apparatus.

A contactless braking system and a related method for decelerating long products (bi) exiting from a rolling mill (100). At least one braking module (6) includes a multiplicity of electromagnets (60) in a series along a braking line (1b). Each magnet has an open magnetic core (61) and a coil (62) around the magnetic core (61). The open magnetic core (61) has a gap formed by two opposed poles. The electromagnets (60) are configured so that the gap of each open magnetic core (61) lets contactlessly slide therethrough each long product (bi) exiting from the rolling mill (100). A braking magnetic force (Fd) is exerted on the long product (bi) contactlessly sliding through the gap. The braking magnetic force (Fd) is opposite to the direction of movement of the long product (bi) exiting the rolling mill (100).

A rolling mill system for Incremental rotary shaping of an elongated workpiece is provided that includes first and second workpiece holders. A support frame has a track with the first and second workpiece holders being movably associated with the track, the workpiece holders and an associated workpiece being movable in unison along the track. A radial chuck is mounted to the frame that includes a plurality of jaws that are movable radially inwardly and outwardly. Each jaw has a tool mounted thereto that is rotatable about an axis of rotation, with the axis of rotation of each tool being oriented at a skew angle relative to the longitudinal axis of a workpiece. A source of electric current and an electrically conductive flow path are provided for flowing electrical current through a workpiece. A controller is provided that is configured to control the operation of each of the first motor, second motor and third motor, and to control the flow of current flowing through the tools to the workpiece.
