Abstract: A guiding method and apparatus are presented for preventing the generation of lateral curving in a rolled slab produced in a roughing mill train, consisting of an edging mill and a horizontal mill in tandem, for example. The apparatus basically includes a first side guide placed upstream at the entrance to the edging mill, a second side guide placed downstream at the exit of the horizontal mill and a third side guide placed between the edging mill and the horizontal mill. The first side guide at the entrance to the edging mill synchronously closes the separation distance of the guide components upon the entry of the rolled slab into the first side guide, leaving a narrow space between the guide and the rolled slab. The third side guide closes the separation spacing based on slab exit timing representing the instant the tail end of the rolled slab passes through the edging mill. The second side guide assumes a narrow separation distance when the head end of the rolled slab enters therebetween.

Abstract: Metal sheets having a low deviation of sheet thickness are produced by rolling a sheet through a finishing rolling mill in which at least a final stand is provided with oil film bearings of a rolling roll, each of which consists of a bushing in a roll chock bearing box and a sleeve tightly fitted to a tapered neck of the roll to form a journal relative to the bushing, and is provided with a key connection fixing the sleeve to the rolling roll in a zone of less than 0.2 times the length of a bearing pressure receiving zone from the end of the tapered fitting zone of the sleeve and the roll neck.

Abstract: An oil film bearing for rolling roll consisting of a bushing in a roll chock bearing box and a sleeve tightly engaged with a rolling roll tapered neck to form a journal to the bushing is improved by that said sleeve is provided with a portion which projects from a smaller diameter end of the rolling roll tapered neck, a keyway is provided in an inner circumference of the projected portion of the sleeve and a holder, by which a radially inner end of the key inserted in the keyway is anchored, is provided at the smaller diameter end of the tapered neck.
