Abstract
Abstract Disclosed are two embodiments of apparatuses for performing work on metallic slabs to substantially reduce their width. In the first embodiment there is provided a pair of driven slab reducing rolls, each rotatably supported in a housing. The rolls are adjustably positioned relative to each other to reduce the slabs to a desired width. Concentrically carried on each roll are a pair of spaced anvil collars, one of which is adjustably positionable relative to the other to accommodate slabs of different thicknesses. In the second embodiment there is provided a pair of adjustably positionable slab squeezer heads, one of which is reciprocated relative to the other. Pairs of platens adjustably support and locate the slab in a direction normal to the movement of the reciprocating squeezer head.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
133 words
Apparatus for reducing the width of metallic workpieces, such as slabs, comprising: a pair of working means operating in the plane of the workpiece for engagement with the opposed edges of said workpiece; drive means connected to each of said working means for generating therebetween a substantial force to reduce the width of the workpiece; adjustment means connected to each of said working means for controlling the relative distance therebetween to produce a workpiece having a desired width; a pair of constraining means including metal reducing surfaces for engaging with the opposed sides of said workpiece in a plane normal to said plane of the workpiece for reducing local increases in workpiece thickness simultaneously with the reduction in width thereof; and means for varying the relative distance between said pair of constraining means.
Claim 2
Dependent Claim
133 words
Apparatus for reducing the width of metallic workpieces, such as slabs, comprising: a pair of working means operating in the plane of the workpiece for engagement with the opposed edges of said workpiece; drive means connected to each of said working means for generating therebetween a substantial force to reduce the width of the workpiece; adjustment means connected to each of said working means for controlling the relative distance therebetween to produce a workpiece having a desired width; a pair of constraining means including metal reducing surfaces for engaging with the opposed sides of said workpiece in a plane normal to said plane of the workpiece for reducing local increases in workpiece thickness simultaneously with the reduction in width thereof; and means for varying the relative distance between said pair of constraining means.
Claim 3
Dependent Claim
55 words
Apparatus according to claim 1 wherein said adjustment means comprises: a support; a nut carried by said support; a screw received in said nut and engageable with said working means; and drive means for causing relative rotation between said screw and said nut to displace said screw and said working means relative to said support.
Claim 4
Dependent Claim
55 words
Apparatus according to claim 1 wherein said pair of working means comprises: a roller having a work surface constructed and arranged to contact an edge of the workpiece; an arbor rigidly secured to said roller; and a chock rotatably supporting said arbor, said drive means coupled to said arbor for transmitting torque to said roller.
Claim 5
Dependent Claim
45 words
Apparatus according to claim 3 wherein said pair of constraining means comprises: first and second collars supported by said arbor in a spaced-apart relationship; each of said collars having a workpiece engaging surface arranged in a direction normal to said work surface of said roller.
Claim 6
Dependent Claim
55 words
Apparatus according to claim 4 wherein said means for varying the relative distance comprises: drive means supported by said first collar and operatively engaging and rotating said second collar relative to said first collar; and mutually engaging threaded surfaceS formed on said collars for varying the relative distance therebetween upon operation of said drive means.
Claim 7
Dependent Claim
76 words
Apparatus according to claim 1 wherein said pair of working means comprises: a pair of squeezer heads each having work surfaces for contact with the edge of a workpiece at a desired elevation; support means for positioning said squeezer heads at said desired elevation; a crosshead for supporting each of said squeezer heads; and tension rods interconnecting said crossheads for resisting the force generated between said squeezer heads incident to reducing the thickness of a workpiece.
Claim 8
Dependent Claim
55 words
Apparatus according to claim 6 wherein said pair of constraining means comprises: a first and second plurality of platens having workpiece engaging surfaces arranged in a direction normal to said work surfaces of said squeezer heads; positioning means connected to said first and second plurality of platens for constraining a workpiece at said desired elevation.
Claim 9
Independent Claim
115 words
A method of producing metallic slabs subsequently to be processed in a rolling mill to produce semifinished or finished products, such as strip, plate, or the like, comprising the steps of: continuously casting molten metal to form a solidified casting having a width greater than the desired width of said products; dividing the casting into slabs of a desired length suitable for subsequent handling and processing; materially reducing the width of the slabs to a predetermined dimension whereby on subsequent processing products having desired thickness and width dimensions will result; and simultaneously engaging the opposite sides of the slab for reducing local increases in the thickness of the slab due to the width reduction thereof.
