    摘要: A split ring for use in assembling a bearing retainer onto a roll. The split ring helps keep a mounting jack in compression with the bearing retainer as the mounting jack compresses the bearing retainer onto the roll. In some embodiments, the split ring includes a plurality of apertures that are each configured to receive a drive mechanism that helps collapse the mounting jack to allow for removal of the split ring and the mounting jack once the bearing retainer is assembled onto the roll.

    摘要: A method for changing rollers in a roll stand adapted for bearing at least one working roller for a continuously-running steel-strip roll mill, includes providing the stand as part of a plurality of roll stands disposed in series along the roll mill in a continuous running direction. A rolling standby function in a free clamping position of the roller(s) is allocated to at least one dedicated stand among the plurality of stands. Original setpoint values controlling an adjustment of the roller clamping are individually allocated to the other stands in an active rolling position. In the case of a roller change when passing into the free clamping position of the stand, the original setpoint value of the stand and the original setpoint values of the stands remaining in an active rolling position are redistributed individually among each of the stands, including the dedicated stand.

    摘要: A modular rolling mill comprises a plurality of separate rolling units arranged along a mill pass line. Each rolling unit includes at least two pairs of work rolls defining oval and round roll passes and carried on roll shafts that are staggered 90° with respect to each other. The rolling units contain intermediate drive trains configured to connect the roll shafts to parallel input shafts projecting to a first side of the pass line from the respective rolling units. A single driven line shaft is parallel to and on the first side of the pass line. Output shafts are mechanically coupled to the line shaft by bevel gear sets. The output shafts project laterally from the line shaft towards the pass line and are connected by separable couplings to the input shafts of the rolling units.

    摘要: An improved rolling procedure is used for forming aluminum alloy sheet product of critical quality, e.g. can body stock, in a hot rolling mill. The mill is of a type in which the rolls are changed on a routine basis at least once during a production week and a plurality of rolled products of different alloy compositions, including sheet product of critical quality, are fed through the hot rolling mill on a sequential basis. In the improved procedure, the aluminum alloy sheet product of critical quality is fed through the rolling mill within the first 72 hours of production time after the rolls have been changed. Also, the order in which different products are to be produced is selected such that products that generate sufficient heat during rolling to cause micro-annealing of the rolls are processed after the sheet product of the critical quality.
