Abstract
Abstract In conventional continuous casting plants and heavy rolling mills, there is a run-out table at the end of the plant or mill, and a cooling bed running at right angles to the run-out table. The invention improves the utilization of factory space by having the cooling bed parallel to the run-out table and by turning the lengths of semi-finished products through about 90* while transferring them from the run-out table to the cooling bed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
270 words
An arrangement for cooling and conveying hot lengths of semifinished metal products coming from a hot forming or hot working process, which arrangement more efficiently utilizes floor space, comprising: at least one run-out table for conveying at least one said length in a direction of conveyance which is substantially parallel with respect to the major axis of said length, and having an end stop for stopping said lengths; at least one cooling bed for conveying said length while it cools in a direction of conveyance which is substantially transverse to said major axis and substantially parallel to the direction of conveyance of the run-out table and downstream thereof, one end of said cooling bed being located adjacent to and upstream said run-out table; and transferring and pivoting means for transferring said length from the run-out table to said one end of the cooling bed while pivoting said length about its major axis approximately 90*, said transferring and pivoting means comprising a pivotal arm normally having its longitudinal axis above and approximately parallel to said run-out table, means mounted on said pivotal arm for picking up said length, and drive means for pivoting said pivotal arm about a vertical axis pivot means at one end thereof which pivot means is located above and upstream saId end stop of the run-out table a distance equal to the length of the longest length of semi-finished metal product, so that by the placement of said one end of the cooling bed adjacent to and upstream said run-out table the overall length of the arrangement is minimized and the floor space is utilized more efficiently.
Claim 2
Dependent Claim
270 words
An arrangement for cooling and conveying hot lengths of semifinished metal products coming from a hot forming or hot working process, which arrangement more efficiently utilizes floor space, comprising: at least one run-out table for conveying at least one said length in a direction of conveyance which is substantially parallel with respect to the major axis of said length, and having an end stop for stopping said lengths; at least one cooling bed for conveying said length while it cools in a direction of conveyance which is substantially transverse to said major axis and substantially parallel to the direction of conveyance of the run-out table and downstream thereof, one end of said cooling bed being located adjacent to and upstream said run-out table; and transferring and pivoting means for transferring said length from the run-out table to said one end of the cooling bed while pivoting said length about its major axis approximately 90*, said transferring and pivoting means comprising a pivotal arm normally having its longitudinal axis above and approximately parallel to said run-out table, means mounted on said pivotal arm for picking up said length, and drive means for pivoting said pivotal arm about a vertical axis pivot means at one end thereof which pivot means is located above and upstream saId end stop of the run-out table a distance equal to the length of the longest length of semi-finished metal product, so that by the placement of said one end of the cooling bed adjacent to and upstream said run-out table the overall length of the arrangement is minimized and the floor space is utilized more efficiently.
Claim 3
Dependent Claim
39 words
An arrangement as claimed in claim 1, including an arcuate track above the cooling bed and supporting means mounted on the end of the pivotal arm for supporting the pivotal arm, said supporting means moving on the arcuate track.
Claim 4
Dependent Claim
33 words
An arrangement as claimed in claim 2, wherein said drive means is arranged at the end of the pivotal arm and is in driving connection with said supporting means, for pivoting the arm.
Claim 5
Dependent Claim
71 words
An arrangement as claimed in claim 1, and further comprising an arcuate track for a support wheel and a toothed track parallel to the arcuate track, and a support wheel and a gear wheel mounted on a shaft on the end of the pivotal arm, the support wheel moving on the arcuate track and the gear wheel moving along the toothed track, said drive means being connected to the gear wheel.
Claim 6
Dependent Claim
43 words
An arrangement as claimed in claim 4, wherein said means for picking up said length comprises a cross-piece, lifting means suspending the cross-piece from the pivotal arm, and two spaced means on the cross piece for independently gripping and picking up said length.
Claim 7
Dependent Claim
21 words
An arrangement as claimed in claim 5, wherein said lifting means comprises rams arranged between the pivotal arm and the cross-piece.
Claim 8
Dependent Claim
17 words
An arrangement as claimed in claim 5, wherein each spaced means has an independent pressure-fluid actuating mechanism.
