Abstract

PURPOSE:To improve shape control functions by effective application of the displacement of press rolls to work rolls in multistages rolling mills having shape control functions by providing the projecting shape crown corresponding to split rolls to the press rolls. CONSTITUTION:In the stage of rolling, a lower work roll 5 is offset in a rolling direction and pressure oil is supplied to cylinders 9-1-9-7 to project piston rods 8-1-8-7 individually by arbitrary extents and to move supporting plates 10-1- 10-7 by arbitrary extents, thereby pressing split rolls 14-1-14-6 to a press roll 15 and giving desired horizontal bending to the roll 15. Then, the roll 5 displaces in a horizontal direction and displaces in a vertical direction as well simultaneously, whereby the roll crown in changed and the shape of a rolled material S is controlled freely.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-high rolling mill equipped with a mechanism for controlling the shape of rolled material.

In recent years, in order to control the thickness shape of rolled material in the width direction,
Although various methods for bending work rolls in four-high rolling mills have been developed and implemented, conventional roll bending methods have had limitations in their ability to control the shape of rolled materials.

That is, in order to obtain a rolled product with a good shape and little change in thickness, especially in the thickness direction, deformation of the work roll due to rolling load etc. should be minimized < L, and the correction ability by roll bending should be increased. This is very important.

Conventional four-high rolling mills only have a vertical roll bedding device, so the amount of crown correction of the rolls is small and only a simple parabolic leg shape is corrected. It was possible to correct the shape of the ears and the inside. In addition, the effect was small on narrow plates of less than % of the roll axis length, and a good shape correction effect could not be obtained.

Therefore, in order to eliminate the above-mentioned drawbacks, one of the upper and lower work rolls is made smaller in diameter than the other, the small-diameter work roll is offset in the rolling direction with respect to the other work roll, and the small-diameter work roll is A multi-roll mill was proposed in which horizontal bending is applied by split rolls via a presser roll parallel to the work roll, and this horizontal bending corrects the roll crown in the vertical direction of the work roll. Since the roll is a split roll, when the presser roll is pressed, the force applied locally is dispersed and the sensitive partial pressure is not transmitted to the work roll because it is via the presser roll. This was done with the purpose of improving the shape control function by greatly and arbitrarily changing the roll crown in the vertical direction of the work roll, and one work roll of the upper and lower work rolls has a smaller diameter than the other work roll. the small diameter work roll is offset in the rolling direction with respect to the other work roll, and a presser roll, a dividing roll, and a horizontal bending device are arranged parallel to the small diameter work roll on the offset side of the small diameter work roll. This rolling mill is characterized in that a convex crown is provided on the outer periphery of the portion of the presser roll that contacts the divided rolls.

In the embodiments of the present invention, a case has been described in which the shaft of the split roll is inserted into a horizontal U-shaped groove provided in the support plate and clamped on both sides. The crystal ball offset and pushed by the presser roll may also be used as the upper work roll, and the actuator that presses the presser roll may be replaced with a fluid pressure cylinder. It goes without saying that a wedge or a screw rod may be used, and that various changes may be made without departing from the gist of the invention.
