Abstract: A seal assembly for use in an oil film bearing rotatably supporting a roll in a rolling mill. The seal assembly includes a flexible seal mounted on a tapered intermediate section of the roll neck for rotation with the roll and within a fixed circular seal end plate. The seal end plate has a stepped interior defining annular inboard and outboard sealing surfaces, with the outboard sealing surface having a diameter larger than the diameter of the inboard sealing surface. The flexible seal has inboard and outboard flanges projecting radially into contact respectively with the inboard and outboard sealing surfaces of the seal end plate.

Abstract: A neck seal is disclosed for use in an oil film bearing assembly for a roll in a rolling mill, the roll having a neck with an intermediate tapered section leading to a reduced diameter end section contained within a sleeve, with the sleeve being fixed in relation to the roll neck and being journalled for rotation in a bushing fixed within a chock. The neck seal is adapted to be mounted on the tapered section of the roll neck for rotation therewith at a location surrounded by a seal end plate fixed to the chock. The neck seal comprises a flexible circular body having axially spaced radially outwardly projecting first and second flanges configured and dimensioned to sealingly contact the seal end plate. First and second axially spaced ridges projecting radially inwardly from the circular body for contact with the tapered section of the roll neck.

Abstract: A sleeve is disclosed for use in an oil film bearing of the type employed to rotatably support a roll neck in a rolling mill. The sleeve has an internally tapered section, an end section aligned axially with the internally tapered section, and a cylindrical outer surface surrounding the internally tapered section. The cylindrical outer surface is adapted to be rotatably journalled in a bushing component of the bearing and has a diameter D of at least 500 mm. The internally tapered section is adapted to be seated on an externally tapered section of the roll neck and has a taper angle greater than three degrees and a minimum thickness of between about 10 mm and 0.024D+14.5. Keyways located outside of the internally tapered section and exclusively in the end section serve to rotatably fix the sleeve to the roll neck.

Abstract: Apparatus for rotatably supporting the neck of a roll in a rolling mill, including a bearing assembly configured and dimensioned to surround the roll neck, a chock containing the bearing assembly, and a support for the chock, with the chock and the support being in contact with each other at an interface having a radius of curvature arranged to accommodate relative movement between the chock and the support in response to bending loads applied to the roll. A lubricant is introduced under pressure at the interface between the chock and the support to thereby reduce frictional resistance to relative movement therebetween.

Abstract: Apparatus is provided whereby maximum options for the treatment of steel rod in direct sequence with rolling are available within a single piece of equipment, all on a single treatment line, and all at convenient, labor free, push-button control. Maximum application of heat to the rod is provided for heat treating, slow-cooling or intermittent reheat cooling or treating, and alternatively maximum application of cooling air is available by means of individually controllable air ducts and guides associated with each roller conveyor for applying air at different pressures both across and/or along the conveyor. Special means for applying forced air to the rod through outlets in contact with the rod assure maximum penetration of cooling air into the dense parts of the lay. Special forms of rollers are provided for applying cooling air to the rod and to the rollers as well as for supporting rod during heat treatment.
