摘要： A sizing press has a pair of opposed rotatably supported pressing tools for reducing the width of a flat metal slab. Piston cylinder assemblies rotatably oscillate the pressing tools relative to each other. Each pressing tool has first and second slab-contacting surfaces which extend in different planes. The invented method of this invention includes the steps of moving the pressing tools toward each other against the sides of a metal workpiece and reducing the width of an initial workpiece length. Thereafter, rotating the pressing tools to further reduce the width of only a portion of the initial workpiece length and to reduce the width of an adjacent workpiece length.

摘要： A shearing apparatus for performing several modes of operation on travelling or stationary material. Two cooperative knife drums, which can be rendered rotatable or non-rotatable, form a gap whose spacing is varied by hydraulic piston cylinder assemblies, one mounted on opposed ends of the upper or bottom drum. The adjustable knife drum is held in a parallel or non-parallel positioning or caused to rock with or without additional high frequency oscillations by controlling and regulating the pressure in the cylinders, while simultaneously moving the upper drum towards the lower drum and/or rotating both drums.

摘要： An arrangement for winding material onto a coiler drum along a passline of a hot reversing mill comprising an apparatus having two pivotal arms mounted on a common shaft and movable in a different arcuate path toward and away from the coiler drum. Rollers at the end of the arms tightly enwrap the material around the drum when the arms are positioned against the drum as the material is being underwound onto the drum. The roller of one of the arms may act as a deflector roller when positioned away from the drum as the material is being overwound onto the drum. The other arm consists of two wrapper rollers on a pivotal mounting for their proper orientation around the drum and for flat passes of the material through the mill. This other arm is positioned away from the drum below the passline to allow a retractable table roll assembly consisting of a plurality of table rolls to be positioned in the passline for supporting the material.

摘要： Method and apparatus for cleaning oxide scale from rolling mill rolls comprises a cleaning spray system including a fluid header juxtaposed to a mill work roll and an associated backup roll and a plurality of nozzles equidistantly spaced along the length of the header. High pressure cleaning water sprays, for which water is supplied by a descaling pump when not in use for descaling, are directed onto a work roll, and by rotation of the header, then directed onto the associated backup roll. The water sprays are directed against the rolls at an angle from 3.degree. to 10.degree. for optimum removal of oxide scale. For even restoration of the roll surface, the cleaning spray system periodically during the cleaning operation is shifted axially along the length of the rolls a distance about one-half the spacing between adjacent nozzles.

A deflector is arranged to interrupt at least a portion of the flow of air such that at least a portion of the wall of water contacts and cools the strip of metal. The flow of air is provided at a pressure of about 50 to 100 psi and, with the flow of air completely blocked by a deflector, the strip of metal is cooled completely across the width of the strip.
