LARGE UNIT WEIGHT HOT-ROLLING PROCESS AND ROLLING APPARATUS THEREFOR

A street bar having a thickness of 20 to 50 mm, as continuously cast by a sheet bar caster, is passed as it is through a first sheet bar twister and is then wound in an up-end state into an up-end sheet bar coil. Then, this up-end sheet bar coil is rewound, passed through a second sheet bar twister, finish-rolled and wound into a hot coil. As compared with the slabbing - high draft rolling process of the prior art, the invention is advantageous in that it can improve the quality, production yield and production efficiency and can reduce the cost for an apparatus such as the cost for its construction and maintenance.

VARIABLE WIDTH TYPE HORIZONTAL ROLL

PURPOSE: To change freely and quickly roll width by remote operation with a horizontal roll having an arbor and a pair of sleeve rolls by sliding the sleeve rolls on the outside circumferential surface of the arbor by fluid pressure. CONSTITUTION: A horizontal roll body is constituted of an arbor 5 and a pair of sleeve rolls 3, 3' fitted onto the outside circumferencial surface of said arbor. Oil injection grooves 6 are provided to the arbor 5. Oil pressure is exerted from a hydraulic device 8 via an oil piping A to the grooves 6 to decrease the coefft. of friction thereby making the rolls 3, 3' slidable. The oil pressure is then actuated from a hydraulic device 9 via an oil piping B and the roll width is detected by detectors 11, 11'. The roll width WR is adjusted to a prescribed space. The devices 8, 9 are controlled by a hydraulic control unit. The H-beams of various sizes are thus produced with high dimensional accuracy of height. COPYRIGHT: (C)1985,JPO&Japio ...

Rolling-mill roll of barrel-width adjustable type

The present invention provides a rolling-mill roll of a barrel-width adjustable type improved in strength by preventing stress concentration in a torque transmission structure for transmitting the torque from drive side roll to another roll. The connecting rod coaxially projected from the drive side arbor is inserted into the sleeve, and the rolls are mounted onto the circumferences of the connecting rod and the sleeve. The connecting rod and the sleeve are supported in a housing via bearings and are coupled with each other by a screw shaft mechanism so that the sleeve is axially movable to vary the barrel width. The complementary engagement between the spline or key for transmitting the torque of the arbor to the sleeve is made at a position offset outward from the axial center of the sleeve bearing so that the complementary engagement is not affected by the bending of the roll due to the rolling reaction and thus a stress concentration is prevented.
