Embodiment Construction

[0022] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0023] The method for adjusting the shape and thickness of the plate in the present invention is to control the thickness and shape of the plate by moving and crossing the work rolls. Symmetrically intersect at 1 / 2 of the width of the rolled steel plate, and the two work rolls move horizontally and laterally to the same side at the intersection point, and work at the positions of both ends of the rolled steel plate, the axis of one end of the upper work roll and the lower work roll The axes of the other ends of the rollers respectively intersect the axes of the backup rollers. The intersection angle α of the upper and lower work rolls is greater than 0 degrees and less than or equal to 1.5 degrees; the offset of the upper and lower work rolls at the intersection is greater than 0 and less than or equal to 15 mm.

Abstract

The plate shape and thickness-controlling rolling method is to use "move work roll" roller mill, where the gap is changed to regulate the plate shape and thickness via transversely shifting and symmetrizing crossed work rolls. The roller mill includes frame, hold down mechanism, upper support roll mechanism, upper work roll mechanism, lower support roll mechanism, lower work roll mechanism, and cross shift mechanism comprising waist block and shift cylinder. The cross shift mechanism is used to replace available expensive automatic thickness controller and results in simple roller mill structure, low cost, low pressure for plate shape and thickness control and raised control precision. In addition, using the hold down cylinder, the waist block and the shift cylinder can realize gap-less rolling.

Description

technical field [0001] The invention relates to a rolling method for controlling the shape and thickness of rolled plates and strips in the metallurgical machinery industry and a gapless rolling mill suitable for the method, that is, a moving work roll (Move Work Roll) rolling mill, MWR rolling mill for short. Background technique [0002] At present, the controllable plate thickness and shape four-roll mills for rolling plates and strips at home and abroad are all occupied by foreign proprietary technologies, such as: the CVC (Continuous Variable Crown) rolling mill produced by German SMS company, the PC (Pair Crossed rolls) rolling mill, etc. The method of controlling the shape of the CVC rolling mill is to use S-shaped upper and lower work rolls, and move the work rolls axially relative to adjust the shape of the plate, but this kind of rolling mill needs a special grinding machine and software to grind the S-roll shape of the work rolls, and special control software.
