Appl. No.:

7/173298

Inventors:

Daniel Jude - Villeneuve D'Ascq, FR
James T. Stull - Evans City PA

Assignee:

Dujardin Montbard Somenor - Seclin Cedex

International Classification:

B22D 1106
F16M 100
F16C 3700
F16C 2306

US Classification:

384476

Abstract:

A mounting device for a roll, particularly a roll for a continuous casting apparatus, comprises a support and a bearing for the roll affixed to the support, the support and the bearing defining channels for the circulation of a cooling fluid therethrough, the support and bearing channels being in communication with each other across a plane of support of the bearing on the support through respective ends of the channels. To assure a fluid-tight connection between the support and bearing channels without precise positioning of the bearing in an axial direction and to enable the vertical position of the bearing with respect to the support to be adjusted, a tubular element is slidingly mounted in a seat at the end of each channel defined in the support or the bearing, a spring element biases each tubular element outwardly from each end into contact with an opposite surface of the support or bearing, the tubular elements having ends maintained in contact with the opposite surface by the spring elements, and a fluid-tight gasket in the cylindrical surface of each tubular element provides a sliding fluid-tight seal between the tubular element and the seat.

Appl. No.:

Inventors:

International Classification:

B22D 1112
B21B 3900

US Classification:

Abstract:

A straightener for a multistrand continuous-casting machine. The straightener includes fulcrum rolls and reaction rolls which precede and follow the fulcrum rolls. The fulcrum rolls for all the strands are idlers and are coaxial, but the reaction rolls which follow the fulcrum rolls and engage intermediate strands are offset in a direction parallel to the length of the strands from the reaction rolls which engage the outer strands. The offset enable the drives for the bottom rolls opposite the intermediate reaction rolls to be connected directly to the bottom rolls.
