摘要： PURPOSE:To hold a work roll stably by determining the offset rate of the work roll and backup roll so as to obtain the horizontal force larger than the swiveling force to be generated in the work roll during cross rolling. CONSTITUTION:A roll offset rate XO is determined rationally by a specific equation and the stable holding of a work roll is made possible in a roll cross rolling mill if the specifications of the rolling mill such as the diameter DW of the work roll, the diameter dB of a backup roll, the distance L between roll chocks, the max. width B of a rolled material, a max. required crossing angle theta, etc. are known. The equation is XO>{(DB+DW)B theta}/12DWLO.

摘要： PURPOSE:To reduce an installation, installation cost, the number of parts, and maintenance cost by crossing a work roll of one side fixed perpendicularly to the advancing direction of a rolling material and a work roll of the other side with each other. CONSTITUTION:In a train of roll cross type rolling mills where upper and lower work rolls are arranged in the rolling direction, and the crossings of adjoining pairs of rolls 11, 11' are inversely set; one of the rolls 11, 11', the roll 11', for instance, is fixed perpendicularly to the advancing direction of a rolling material. And the roll 11 is made slantable with respect to the roll 11'. That is, both ends of the roll 11' are supported by lower work roll chocks 13'a, 13'b and are fixed perpendicularly to the advancing direction of the material. On the other hand, both ends of the roll 11 are supported by upper work roll chocks 13a, 13b and are moved backward and forward by driving mechanisms 16a 16b, 17a, 17b through crossheads 14a, 14b, 15a, 15b.

摘要： PURPOSE:To easily make a rolling roll cross with the other roll at an arbitrary angle, by pressing a bearing box of a rolling roll of a horizontal mill by a spherical surface bearing attached to a slantable pedestal. CONSTITUTION:Bearing boxes 2 at both ends of a rolling roll 1 at one side of a horizontal mill are brought into contact with a pedestal 4 which is used for pressing the bearing boxes 2 of the roll 1 and is housed in a housing 3, and the box 2 is pushed by the pressure of a driving shaft 8 in the direction slanted at an angle theta with respect to the rolling axis of the roll 1 Y-Y and in the Y1-Y1 direction to make the roll 1 axis cross with the axis of the other roll by an angle theta at the time of rolling. In this case, the pedestal 4 for pressing the bearing box 2 of the rolling roll shaft functioning as a rolling-roll crossing mechanism is protected at its tip by a liner 5, and is in contact with the bearing box 2 through the surface between a liner 9 of the box 2 and the liner 5, and also, a spherical-surface bearing 6 is disposed between the pedestal 4 and the driving shaft 8. Thus a crossing of the rolling rolls with each other is freely performed at an arbitrary angle because the pedestal 4 is made slantable with respect to the shaft 8.

摘要： PURPOSE:To enable grinding of the entire or optional area of a roll body length to a prescribed profile in a method for pressing the adjacent rolls of a cross roll type rolling mill in contact with each other and polishing the rolls by moving specifically the rolls. CONSTITUTION:Respectively paired work roll 1 and backup roll 3 as well as a work roll 2 and a backup roll 4 are crossed at an optional angle theta in the direction perpendicular to rolling in grinding lower roll groups, 2, 4 of, for example, a cross roll type 4-high rolling mill. The rolls 1, 2 are pressed to contact with each other without biting a rolling material therebetween at the same instant and the rolls 1-4 are rolled to start grinding. As a result the rolls are polished to each other into a belt shape of a slight width with the point O' as a center as the rolls 2, 4 contact with each other at the crossing point O' thereof. The position of the point O' is thereupon moved at an adequate speed between the roll body lengths along the direction perpendicular to rolling by operating the crossing mechanism while the upper and lower roll groups or either thereof is maintained at the angle theta, by which the polishing is accomplished.

摘要： PURPOSE:To reduce a thrust at the time of hot roll-kissing by removing cooling water on the surface of a roll with the aid of a draining board and spraying a mineral oil on the surface to improve an adherability of the oil, in work rolls of a hot cross-roll mill. CONSTITUTION:In cooling hot cross work-rolls 2, 2' by cooling water jetted from nozzles 5, 5', the water on the surfaces of rolls 2, 2' is removed by draining boards 6, 6', and a mineral oil is sprayed on the water-removed roll surfaces by spraying nozzles 7, 7' to provide oil films of excellent adherability onto the surfaces. Thrusts acting on bearings during rolling are reduced by the oil films; especially at the time of roll-kissing, the thrusts are remarkably reducded to protect the bearings.

摘要： PURPOSE:To reduce the friction coefficient and thrust between rolls, and to prevent bearing troubles, by shifting the timing of stopping the injection of a rolling oil during the idle time after a rolling material runs out of the rolls. CONSTITUTION:The period of feeding a rolling oil into an idle time is prolonged by 5 and 20 seconds even after the tail end of a rolling material runs out of rolls, and also the rolling oil sticking to the rolls is washed out by a roll cooling water, before the following material is bitten by the rolls, to increase friction coefficient. At that time, if said timing is prolonged by 25 seconds till the feed of oil is made off, the effect for washing out the oil is reduced, and slip is caused when the following material is bitten.
