System and method to harden rails by cooling, in a cooling medium, at least one part of a respective rail cross-section of a rail over an entire length of the rail. The system includes a cross displacement device arranged in an area of a roller table, at least one coolant container containing the cooling medium, a manipulation gripper structured and arranged to move the rail, and at least one positioning device comprising substantially horizontally aligned holding components having fittings structured and arranged to support a foot portion of the rail such that the rail hangs from the fittings.

System and method for hardening rails

System and method for hardening rails by cooling, in a cooling medium, at least one part of a respective rail cross-section of a rail over an entire length of the rail. The system includes a cross displacement device arranged in an area of a roller table, at least one positioning device, at least one coolant container containing the cooling medium, a manipulation gripper comprising a plurality of pincers and being structured and arranged to move the rail. The method includes at least one of moving the rail from the roller table to the at least one coolant container positioning the rail into the at least one positioning device via the manipulation gripper, as well as moving the rail into the coolant medium with the at least one positioning device.

Device for joining faces of parts having great longitudinal extension by friction welding. The device includes first and second clamping arrangements structured and arranged to position ends of the parts against one another. At least one of the first and second clamping arrangements is axially movable with respect to another of the first and second clamping arrangements. At least one of the first and second clamping arrangements is movable along a direction that is parallel to a part cross-sectional plane defined by an end face of one of the parts.

Device and method for joining the faces of parts

Device for joining faces of parts having great longitudinal extension by friction welding. The device includes first and second clamping arrangements structured and arranged to position ends of the parts against one another. At least one of the first and second clamping arrangements are axially movable with respect to another of the first and second clamping arrangements. At least one of the first and second clamping arrangements are movable along a direction that is parallel to a part cross-sectional plane, whereby the part cross-sectional plane is define by an end face of one of the parts. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

The process for metallically connecting the faces of rods. Axially normal dressing at least two rod free ends, then placing the cross sectional surfaces of the rod free ends one against another under pressure. Oscillating the two rod free ends in the opposite direction to one another, whereby frictional heat is generated on the contact surfaces of the rod free ends. Further, when the conditions for a metallic connection are met, the rod free ends are axially aligned and the pressurization of the cross sectional areas is increased. Resulting in the rod free ends being connected to one another over the entire surface. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
