Continuous casting apparatus for slabs

Claim 2

Continuous casting apparatus for slabs, comprising: first and second mould means, arranged in closely spaced, side-by-side relationship; a common distributor groove for supplying melt to said mould means; first and second independent guide tracks operatively connected respectively to said first and said second mould means, and arranged in side-by-side relationship located as closely adjacent each other as possible, each of said independent guide tracks having idler rollers and individually driven rollers for guiding a cast slab; first motor means located on the free outside of said first guide track, and connected to the driven rollers of said first guide track; second motor means also located on the free outside of said first guide track; and drive shaft means extending across said first guide track from said second motor means to the driven rollers of said second guide track, and connected to said driven rollers of said second guide track.

Claim 3

Continuous casting apparatus according to claim 1, wherein said drive shaft means for each driven roller of said second guide track extends through an idler roller of said first guide track means and is connected to the end of an aligned driven roller of said second guide track, the idler roller of said first guide track through which said drive shaft means extends being mounted for free rotation on said drive shaft means passing therethrough.

Claim 4

Continuous casting apparatus according to claim 1, wherein said drive shaft means associated with each driven roller of said second guide track crosses both tracks and extends to the free outside of the second guide track, and wherein a driving connection is provided between the respective drive shaft means end and the driven roller on the free outside of said second guide track.

Claim 5

Continuous casting apparatus according to claim 3, wherein the drive shaft means crossing both tracks are guided through tubular cross members of an arc-shaped carrier frame of each guide track.

Claim 6

Continuous casting apparatus according to claim 1, comprising additionally a third guide track, the driven rollers of which are driven from the free outside thereof.

Claim 7

Continuous casting apparatus according to claim 1, comprising two twin casting guide tracks which are disposed mirror-symmetrically to each other and each of which has a first and a second casting guide track.

Claim 8

Continuous casting apparatus according to claim 6, wherein each guide track comprises an arc-shaped carrier frame with two parallel frame parts which are provided with pockets open towards the centre of curvature of the frame for receiving stub axle bearings of the rollers, wherein all guide tracks are associated with a common roller dismantling device comprising a transverse member which extends over the total width of the apparatus and which is guided in arc-shaped running rails and on which a dismantling carriage is guided which is displaceable transversely to the guide tracks.

Claim 9

Continuous casting apparatus according to claim 1, having adjustable moulds for changing the width of the slabs, wherein only the outwardly disposed narrow walls of the moulds are adjustable.

Claim 10

Continuous casting apparatus according to claim 1, wherein the moulds of a twin track are disposed on a common lifting table.

Claim 11

Continuous casting apparatus for slabs, comprising: first and second mould means; a common distributor groove for supplying melt to said mould means; first and second casting guide tracks operatively connected respectively to said first and second mould means, each of said guide tracks having idler rollers and individually driven rollers for guiding a cast slab; and motor means for driving said driven rollers, wherein said motor means for driving the driven rollers of said first guide track and said motor means for driving the driven rollers of said second guide track are disposed on the same free outside of said first guide track, and wherein said first and second guide tracks are located as closely adjacent each other as possible, the driven rollers of the second guide track each being connected to a driven shaft which traverses in the form of a carrier shaft the in-line roller of the first guide track, the said roller being in the form of an idler roller which is freely rotatably mounted on this carrier shaft, and wherein an adjacent roller of the first guide track is positively driven.

Claim 12

Continuous casting apparatus for slabs, comprising: first and second mould means; a common distributor groove for supplying melt to said mould means; first and second casting guide tracks operatively connected respectively to said first and second mould means, each of said guide tracks having idler rollers and individually driven rollers for guiding a cast slab; and motor means for driving said driven rollers, wherein said motor means for driving the driven rollers of said first guide track and said motor means for driving the driven rollers of said second guide track are disposed on the same free outside of said first guide track, and wherein said first and second guide tracks are located as closely adjacent each other as possible, the driven rollers of the second guide track each being connected to a driven shaft which traverses in the form of a carrier shaft the in-line roller of the first guide track, the said roller being in the form of an idler roller which is freely rotatably mounted on this carrier shaft, and wherein an adjacent roller of the first guide track is positively driven.
