Abstract: The crown on a steel strip in a rolling mill is controlled by a continuous rotational adjustment of an arbor in response to a control signal representing the current crown profile or deviation therefrom, the arbor being equipped with a curved eccentric contour, bearing rollers surrounding the arbor and a continuous sleeve around the bearing rollers.

Abstract: A device for removing dross from the surface of the molten metal and for extracting usable elemental metal from the dross. The device comprises a container in which the dross is collected, a means for lifting the container out of the molten bath of metal and an agitating means for chopping the dross to separate the elemental metal from the particles of metal oxides contained in the dross. Preferably, the container has perforations therein such that the elemental metal may drain through the perforations and back into the molten bath. The remaining dross is then dumped in a recycle bin by the device.

Abstract: The crown on a steel strip in a rolling mill is controlled by a continuous rotational adjustment of an arbor in response to a control signal representing the current crown profile or deviation therefrom, the arbor being equipped with a series of eccentric rings fixed thereto, bearings surrounding the rings, and a continuous or segmented sleeve around the rings. Where the sleeve is segmented, use of an intermediate roll is suggested.

Abstract: A starter bar is designed for beam blank production by continuous casters. The starter bar has a unique transition section including H-profiled segment members which are fixed to an elongated flexible steel band forming the core of the unit. The transition section is readily connected and disconnected to a universal tail section, also having an elongated flexible steel band as its core.

Abstract: An improved plate leveller comprising a housing, a rigid top beam and a bottom beam mounted on the housing, a flexible beam disposed between the upper rigid beam and the bottom beam and connected at the ends thereof to secondary bending cylinders mounted on the rigid top beam, upper back-up roll assemblies mounted on the flexible beam, lower back-up roll assemblies mounted on the lower beam, upper and lower work rolls disposed between the back-up roll assemblies, and a primary bending cylinder mounted on the rigid top beam and bearing on an upper surface of the flexible beam and, with the secondary bending cylinders, bending the flexible beam to counteract deflection of the bottom beam under load, thereby to maintain the upper and lower work rolls in parallel relationship to each other and providing uniform dimensions of plate passed therebetween.

Abstract: Apparatus for continuously measuring the width of a continuously cast steel slab moving along a roller table including a pair of measuring rolls slidably mounted to a guide rail, one on each side of the slab, and further including an air cylinder interconnected between the two measuring rolls adapted to bias the measuring rolls towards each other sufficient to bring them into contact with, and roll against, the slab sides while the slab is in motion, so that the distance between the contacting surfaces of the measuring rolls will be a measure of the slab width. The slidably mounted cylinder permits measuring roll contact with a slab that is not travelling on center of a roller table.

Abstract: 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.

Abstract: A modular slab caster or the like is provided having a flat foundation mat supporting a ladle turret module, a tundish module, a mold oscillator module, at least one adjustable segment module, a straightening module, a starting bar handling and charging module and a utility module, all on said foundation mat and rapidly connected and disconnected from one another to provide rapid installation of modules.

Abstract: A top roller apron in a continuous casting assembly, including a back face side frame, an inside face side frame, and a pair of narrow-face frames positioned on both sides of the side frames, a plurality of rolls mounted side by side to each of the side frames, wherein the back face side and inside face side frames each include unit roll frames, the unit roll frames being arranged in series in a casting direction and each supporting an single roll and wherein opposite end portions of each said roll frame are removably attached to side walls of the paired narrow-face frames.

Abstract: A tundish car in a continuous casting assembly which includes wheel supporting frames for supporting a pair of front wheels and a pair of rear wheels, and lift mechanisms respectively mounted above the wheel supporting frames, two pairs of the wheel supporting frames being connected respectively through interwheel frames, each right and left pair of the lift mechanisms being connected through a lift frame which supports a tundish.

Abstract: A mold-oscillating apparatus in a continuous casting assembly which includes a mold table, a base frame, first and second driven eccentric shafts, a drive mechanism connected to each of the first and second shafts, first and second stationary bearing housings connected to the base frame and within which the first and second shafts are respectively mounted, first and second moving bearing housings connected to the mold table and within which the first and second shafts are respectively mounted and a connecting beam interconnecting the mold table with the first and second moving bearing housings wherein the mold table is oscillated via the connecting beam upon rotation of the first and second shafts by the drive mechanism.

Abstract: A continuous casting mold assembly that includes a mold unit including a pair of wide mold walls each having a wide copper plate supported on the inner side of a back-up frame and a pair of narrow mold walls each having a narrow copper plate supported on the inner side of a back-up frame and gripped between the wide mold walls; a water supply frame including a datum-side water supply frame adapted to support and determine the position of one of the wide mold walls on the back side thereof, and an adjustable-side water supply frame adapted to support the other wide mold wall for movement in clamping and unclamping directions in parallel relation with the opposing wide mold wall; a clamp mechanism mounted on the part of the water supply frame and operable to clamp the other wide mold wall toward the opposing wide mold wall to grip the narrow mold walls securely therebetween; and a narrow mold wall shift mechanism mounted on the part of the water supply frame to adjust the spacing between the two narrow mold wal

Abstract: A starter bar has a starter bar head attached to a rear end portion thereof, the plate type starter bar being formed by a relatively thin plate. A starter bar handling device for effecting storage and charging of the plate type starter bar for clamping and swinging portions of the starter bar.
