Abstract

Abstract A slab emerging from a casting mold is supported by an articulated roller chain resiliently biased and mounted to a frame. Groups of rollers comprising such chain are mounted to equalizing brackets, and one group of rollers is secured to a piston-cylinder assembly. When the piston cylinder assembly is actuated, the rollers connected thereto exert a bending force on the slab which curves and is supported by the articulated roller chain.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 289 words
A continuous casting machine comprising: a. a tundish containing molten metal that flows into b. a vertically reciprocable mold wherein the molten metal partially solidifies and from which a cast slab continually emerges; c. a plurality of rollers disposed below said mold that exert reactionary forces on such slab; d. a support frame; e. means pivotally supporting one end of said frame; f. means connected to the other end of said frame for holding said frame in operative relation to said mold; g. a flexible chain for supporting said slab after it emerges from said mold said chain comprising: i. a plurality of pairs of roll brackets pivotally interconnected together, each said bracket including 1. a fixed bearing and a movable bearing, with ii. a pair of rollers journaled in each pair of brackets and on opposite sides of said slab, with iii. means for moving said movable bearing relative to said fixed bearing; h. means pivotally connecting one end of said flexible chain to said frame at a location adjacent said plurality of rollers; i. means connected to the other end of said flexible chain for linearly extending said chain; j. equalizer arms pivotally mounted to said frame; k. first equalizer brackets mounted to said equalizer arms with each first equalizer bracket being mounted to a roller bracket; l. second equalizer brackets mounted to said equalizer arms with each second equalizer bracket being mounted to a roller bracket, said first equalizer brackets being disposed and spaced-apart relation to such second equalizer brackets; and m. means connected to said equalizer arm urging the rollers in the brackets mounted to said second equalizer brackets against said slab to bend said slab about the rollers mounted to the first equalizer brackets.
Claim 2
Dependent Claim 289 words
A continuous casting machine comprising: a. a tundish containing molten metal that flows into b. a vertically reciprocable mold wherein the molten metal partially solidifies and from which a cast slab continually emerges; c. a plurality of rollers disposed below said mold that exert reactionary forces on such slab; d. a support frame; e. means pivotally supporting one end of said frame; f. means connected to the other end of said frame for holding said frame in operative relation to said mold; g. a flexible chain for supporting said slab after it emerges from said mold said chain comprising: i. a plurality of pairs of roll brackets pivotally interconnected together, each said bracket including 1. a fixed bearing and a movable bearing, with ii. a pair of rollers journaled in each pair of brackets and on opposite sides of said slab, with iii. means for moving said movable bearing relative to said fixed bearing; h. means pivotally connecting one end of said flexible chain to said frame at a location adjacent said plurality of rollers; i. means connected to the other end of said flexible chain for linearly extending said chain; j. equalizer arms pivotally mounted to said frame; k. first equalizer brackets mounted to said equalizer arms with each first equalizer bracket being mounted to a roller bracket; l. second equalizer brackets mounted to said equalizer arms with each second equalizer bracket being mounted to a roller bracket, said first equalizer brackets being disposed and spaced-apart relation to such second equalizer brackets; and m. means connected to said equalizer arm urging the rollers in the brackets mounted to said second equalizer brackets against said slab to bend said slab about the rollers mounted to the first equalizer brackets.
Claim 3
Dependent Claim 51 words
The invention of claim 1 wherein: a. said means for linearly extending said chain includes: i. an arm pivotally mounted to said frame, ii. a link connecting said arm to said chain, and iii. resilient bias means engaging said arm to pivot it and urge said chain in a linear direction.
Claim 4
Dependent Claim 82 words
The invention of claim 2 including: a plurality of pairs of other roll brackets pivotally interconnected together, each said roll bracket including: i. a fixed bearing and a movable bearing, with ii. a pair of rollers journaled in each pair of roll brackets, and iii. means for moving said movable bearing relative to said fixed bearing; and b. means connecting each pair of other roll brackets to said frame whereby said other roll brackets are maintained in spaced-apart relation to said frame.
Claim 5
Dependent Claim 38 words
The invention of claim 3 wherein: a. said plurality of pairs of other roll brackets are connected to said flexible chain; and including b. means for linearly moving said plurality of other roll brackets relative to said frame.
Claim 6
Dependent Claim 29 words
The invention of claim 1 wherein: a. said means connected to the other end oF said frame includes a wire rope that is operatively connected to a powered winch.
Claim 7
Dependent Claim 44 words
The invention of claim 1 wherein: a. said means pivotally supporting said frame includes: i. arms fixed to said frame that engage ii. a pivotable support, and iii. means for pivoting said support for adjusting the position of the one end of said frame.
Claim 8
Dependent Claim 27 words
The invention of claim 1 including: a. a backup roller coacting with each pair of said plurality of rollers that coact with one side of said slab.
