摘要: A method and an apparatus for rolling metal strips by a tandem cold rolling mill. The strip is periodically swung in its width directions at a location upstream of the tandem rolling mill, to bring the strip into contact with rolls of the tandem cold rolling mill over areas of the rolls as widely as possible, thereby preventing irregular wears of the rolls to make it possible to produce defect-free metal strips.

摘要: The invention relates to a taper journal bearing for rolls, used in rolling mills. The bearing includes a bushing installed in a roll bearing box, a sleeve closely fitted onto a taper journal of the roll, for supporting a load thereof, an oil film deposited between the bushing and the sleeve, and means for attaching the sleeve to the roll at an area other than that directly subjected to a rolling force. The invention eliminates the increased variation in the reduction force taking place at each rotation of the roll, due to a deformation of the sleeve. The latter is caused by a clearance at a keyway formed in the sleeve, for a key arranged between the sleeve and the taper journal.
