摘要： A guide roller for a continuous casting machine includes a roller seat having bearings, a roller shaft mounted for rotation in the roller seat and at least one roller body mounted on the roller shaft and configured to support a billet. A passive optical sensor is mounted to the roller seat and configured to output optical signals, and an optical fiber extends from the passive optical sensor and is configured to convey the optical signals to a processor configured to determine one or more physical parameters of an installation position of the passive optical sensor based on the optical signals.

摘要： A bearing block unit for supporting a continuous casting roll, including a bearing block and a roller bearing disposed inside the bearing block. The bearing provides an inner ring raceway, an outer ring raceway, and at least one row of rolling bodies disposed between the inner and outer ring raceways. The inner ring raceway is formed by a complete and continuous independent inner ring. The inner ring is fitted on a roll shaft of the continuous casting roll during installation, for the purpose of supporting the continuous casting roll. The outer ring raceway is at least partially formed by processing of an inner surface of an inner hole of the bearing block. The present invention also relates to a continuous casting roll line and a continuous casting machine using the bearing block unit.

摘要： A support unit for a roll shaft of a continuous casting guide roll includes a housing having first axial end face, a second axial end face and a through-opening extending from the first axial end face to the second axial end face, a first cover connected to the first axial end face, a first primary isolator arranged radially between the first cover and the roll shaft, and a bearing in the through opening. On a first side of the bearing, a first closed space is partially defined by the bearing, the first cover and the first primary isolator, and the first closed space is pre-filled with a lubricant.

摘要： A bearing housing is provided with a cooling channel in at least part of the circumference around the bearing. The cooling channel is provided with a flow guide member at least in part of its flow section to construct a tortuous passage whose flow distance is longer than the corresponding circumferential length of the flow section. On the basis of the above-mentioned bearing housing, the present invention also provides a bearing housing unit, a continuous casting roll line and a continuous casting machine that use the bearing housing. The above-mentioned bearing housing adopts an optimized cooling channel design, which can obtain a better cooling effect without changing other structures of the bearing housing. Therefore, it is particularly suitable for upgrading existing equipment and has a huge cost advantage and a wide range of application prospects.
