The invention concerns a roller and a roller arrangement for a continuous casting installation comprising two bearing blocks and the roller carried by the bearing blocks, wherein the roller has a rotationally symmetrical roller casing and wherein the roller bearing is arranged within the roller casing.

Roll and roll arrangement for a continuous casting installation

A device for coupling a coolant supply to a roller, in particular for continuous casting installations, wherein the roller is supported for rotation in a stationary pillow block, includes a sealing unit coupled to an axial roller borehole in a pressure-tight manner, and a stationary pillow block cover releasably attached to the pillow block and covering the axial roller borehole. An insert may extend through a center opening of the pillow block cover and be attached to the pillow block cover by a flange. The inside diameter of the center opening of the pillow block cover may be greater than an outside diameter of the bush to enable a removal of the sealing unit from the roller borehole without removal of the pillow block cover.

Device for coupling a coolant supply to a roller

A device for connection of a coolant feed to a roller, especially for continuous casting plants, is arranged in that the roller is mounted by journals in bearing blocks in rolling bearings and is supplied with coolant by way of axial bores through the journals. The device includes a flange with an elastic sleeve that is fixable thereon. A first sealing element has a first sealing surface that is fixable on the elastic sleeve and is rotatable therewith. A second sealing element has a second sealing surface engagable with the first sealing surface and is fixed to, supported by or integrated into a bearing block cover fixed on the bearing block for covering the roller bore and the roller bearings. An axial bore penetrates the elastic sleeve and the bearing block cover and permits feeding of coolant into the interior of the roller. The sealing surfaces of the sealing elements are perpendicular to the rotation axis.

Rotatable lead-through

A device for coupling a coolant supply to a roller, especially for continuous casting installations mounts the roller in a pillow block via journals and roller bearings. The roller can be supplied with a coolant via at least one axial borehole guided through the journals. The device includes a sealing unit, preferably in the form of an elastic sleeve, that can be fixed to the journal in a pressure-tight manner, in order to carry out the coupling to the borehole and a pillow block cover that can be fixed to the pillow block for covering the borehole and includes at least one coolant channel that can be connected to the coolant supply. An insert can be introduced into the pillow block cover in order to couple the borehole to the coolant channel.
