US4146083A — Arcuate supporting and guiding construction for c…

Claim 1

Independent Claim 280 words

In an arcuate supporting and guiding construction for continuously cast strands, in particular slabs, of the type including a framework, a set of inner arcuate longitudinal carriers and a set of outer arcuate longitudinal carriers positioned within the framework, and a plurality of rollers connected to each of the sets of longitudinal carriers to form roller paths supporting the strand on two opposite sides thereof, the improvement comprising: at least two oppositely arranged framework parts carrying one roller path each, one of the at least two framework parts being arranged to rest on the other along contacting faces when they are in an operating position; a plurality of drawing anchors holding the contacting faces in abutment when in a connection position and being arranged at right angles to the arcuate roller paths so as to attach the oppositely arranged framework parts together when the framework parts are in the operating position, the drawing anchors being distributed over the longitudinal extension of the arcuate longitudinal carriers at a distance from one another; anchor adjustment means for extending said drawing anchors into the connection position and retracting them from said connection position; connecting means for connecting said drawing anchors to the at least two framework parts, said connection means being arranged so that the drawing anchors are detachable from at least one of said framework parts so that they can be brought out of the connection position by said adjustment means; and means for moving one of said framework parts with respect to the other when the drawing anchors are retracted from the connection position, whereby the framework parts are removed from the operating position and no longer rest on each other.

Claim 2

Dependent Claim 280 words

In an arcuate supporting and guiding construction for continuously cast strands, in particular slabs, of the type including a framework, a set of inner arcuate longitudinal carriers and a set of outer arcuate longitudinal carriers positioned within the framework, and a plurality of rollers connected to each of the sets of longitudinal carriers to form roller paths supporting the strand on two opposite sides thereof, the improvement comprising: at least two oppositely arranged framework parts carrying one roller path each, one of the at least two framework parts being arranged to rest on the other along contacting faces when they are in an operating position; a plurality of drawing anchors holding the contacting faces in abutment when in a connection position and being arranged at right angles to the arcuate roller paths so as to attach the oppositely arranged framework parts together when the framework parts are in the operating position, the drawing anchors being distributed over the longitudinal extension of the arcuate longitudinal carriers at a distance from one another; anchor adjustment means for extending said drawing anchors into the connection position and retracting them from said connection position; connecting means for connecting said drawing anchors to the at least two framework parts, said connection means being arranged so that the drawing anchors are detachable from at least one of said framework parts so that they can be brought out of the connection position by said adjustment means; and means for moving one of said framework parts with respect to the other when the drawing anchors are retracted from the connection position, whereby the framework parts are removed from the operating position and no longer rest on each other.

Claim 3

Dependent Claim 37 words

An arcuate supporting and guiding construction as set forth in claim 1, wherein at least one of the sets of longitudinal carriers is elastically deformable and braceable relative to the framework for adjustment to various strand thicknesses.

Claim 4

Dependent Claim 34 words

An arcuate supporting and guiding construction as set forth in claim 1, wherein the framework is divided parallel to the roller paths into a roller-path-carrying arc-outer framework part and a roller-path-carrying arc-inner framework part.

Claim 5

Dependent Claim 53 words

An arcuate supporting and guiding construction as set forth in claim 3, wherein the drawing anchors are arranged on the arc-outer framework part so as to be displaceable in their longitudinal direction, and the anchor adjusting means are arranged for retracting said drawing anchors from their connection position into the arc-outer framework part.

Claim 6

Dependent Claim 20 words

An arcuate supporting and guiding construction as set forth in claim 4, wherein the adjusting means are pressure medium cylinders.

Claim 7

Dependent Claim 124 words

An arcuate supporting and guiding construction as set forth in claim 3, wherein said drawing anchors each include a longitudinal slot and said connecting means comprises: wedges allocated to the arc-inner and arc-outer framework parts, the wedges allocated to the arc-inner framework part being adapted to be pushed into each drawing anchor longitudinal slot in order to connect the framework parts, the wedges allocated to the arc-outer framework part being rigidly connected thereto and each drawing anchor being displaceable with its pertaining longitudinal slot along the pertaining rigidly connected wedge by means of said anchor adjustment means, and wedge adjustment means for bringing the wedges allocated to the arc-inner framework part into and out of engagement with the slots of the pertaining drawing anchor.

Claim 8

Dependent Claim 41 words

An arcuate supporting and guiding construction as set forth in claim 6, wherein the wedge adjustment means for bringing the wedges allocated to the arc-inner framework part into and out of engagement with the pertaining drawing anchor are pressure medium cylinders.

Claim 9

Dependent Claim 47 words

An arcuate supporting and guiding construction as set forth in claim 3, further comprising a fixed bearing and an expansion bearing to support the arc-outer framework part and lifting means provided in said fixed bearing and said expansion bearing for lifting and lowering said arc-outer framework part.

Claim 10

Dependent Claim 31 words

An arcuate supporting and guiding construction as set forth in claim 3, further comprising a carrying structure and brackets for hinging the arc-inner framework part to the carrying structure with play.

Claim 11

Dependent Claim 29 words

An arcuate supporting and guiding construction as set forth in claim 3, further comprising a carrying structure and lifting elements hinging the arc-inner framework part to the carrying structure.

Claim 12

Dependent Claim 20 words

An arcuate supporting and guiding construction as set forth in claim 10, wherein said lifting elements are pressure medium cylinders.

Claim 13

Dependent Claim 39 words

An arcuate supporting and guiding construction as set forth in claim 3, further comprising a horizontally displaceable car and lifting elements for depositing the arc-outer framework part, after separation from the arc-inner framework part, on the horizontally displaceable car.

Claim 14

Dependent Claim 36 words

An arcuate supporting and guiding construction as set forth in claim 3, further comprising a horizontally displaceable car and lifting means for depositing the complete, unseparated arcuate supporting and guiding construction on the horizontally displaceable car.
