Integrated control method of double-six roller UCM type flattening machine group plate shape

Abstract

The invention discloses a method for comprehensively controlling a plate shape of a double six-roller UCM model temper mill unit. The method is characterized by comprising the following steps: a. collecting equipment parameters of the double six-roller UCM model temper mill unit; b. collecting key rolling technology parameters of a strip material to be comprehensively set; c. calculating optimum setting values of working rolls of 1# frame and 2# frame, ,roll bending of an intermediate roll and movement of the intermediate roll; and d. carrying out comprehensive setting to roll bowing force of the movement of the 1# frame and the 2# frame on the unit according to calculated optimum movement and comprehensive setting value of the roll bowing force. The comprehensively controlling method provided by the invention not only can improve controllability to the plate shape by the roll bending of the working roll and the intermediate roll of the double six-roller UCM model temper mill unit, movement of the intermediate roll and other plate shape control modes, bring full play of roll bending and movement and improve the plate shape quality of a finished product, but also can improve the service life of a roller, and reduce roll consumption, so as to bring significant economic benefit for company.

Description

technical field [0001] The invention relates to a skin-passing production technology, in particular to a method for comprehensively controlling the shape of the 1# and 2# racks of the double-six-roller UCM type skin pass unit, such as bending rolls and shifting rolls. Background technique [0002] attached figure 1 It is a schematic diagram of the production process and equipment layout of the double six-roller UCM type skin pass unit. as attached figure 1 As shown, the strip 1 is uncoiled from the uncoiler 2 and then sent to the frame. After being rolled by two stands, the strip 1 reaches a specified thickness and is sent to the coiler 3 for rewinding. The rolls of each stand include work rolls 4, intermediate rolls 5 and backup rolls 6, and the work rolls are in direct contact with the strip surface. as attached figure 2 As shown, in order to control the strip shape, during the rolling process, 1# and 2# stands have the strip shape control means of work roll bending, ...

Problems solved by technology

At this time, if the shape control parameters of the six parts of the two racks are set independently instead of coordinated with each other, it is very easy to appear that the effects of the six parts of the shape control parameters of the two racks cancel each other out, weakening the The effect of these control methods on the control of the shape of the plate is reduced; what is more serious is that when the settings of the control parameters of the six parts of the two racks are not coordinated, the combined effect will even bring new additional local wave shape problems
