摘要： A method and a corresponding computer program product calculate a pass schedule for a stable rolling process when rolling metal strip in a rolling mill. The offset here is varied until the calculated target horizontal force satisfies a predefined limit criterion. The satisfaction of the limit criterion means that the set of rolls and the rolling process are stable. For cases in which a sole iteration of the offset of the working roll does not result in the limit criterion being satisfied, the present invention provides that the draws on the material to be rolled are then changed on the feed side and/or on the outlet side of the rolling stand with constant offset until the calculated target horizontal force satisfies the limit criterion.

摘要： Systems and methods for using full-width hot sprays to pre-heat rolling mills prior to processing of metal sheet or plate are described herein. The hot sprays may be individually controlled. Using hot sprays can allow the rolling mill to reach operating temperature and achieve a desired thermal crown so that metal sheet or plate may be processed immediately within tolerances for flatness and gauge accuracy. Pre-heating of rolling mills can eliminate the need of the rolling mill to operate in a transitional period of work roll heating and can increase efficiency by eliminating or reducing scrap material and mill downtime. Hot sprays may also be incorporated with existing coolant systems to provide thermal control systems for rolling mills with bi-directional temperature controls.

摘要： A Steckel mill has a reversing unit for rolling a rolled product and winding furnaces arranged on the entrance side and exit side of the reversing unit. When rolling the rolled product in a region of a head of the rolled product, a target thickness of the rolled product is ignored, while measuring a current thickness and/or a hardness of the rolled product and comparing this with a setpoint value. One the measured variable reaches or is below the setpoint value, the reversing unit is operated with a view to achieving the target thickness of the rolled product. The Steckel mill is operated to allow for rolling of a cold, non-rollable piece of the rolled product, so that malfunctions are avoided and the usable part of the rolled product is as large as possible.

摘要： A method for altering the width of a strip-shaped rolled material (5), before, during or after hot rolling the rolled material in a hot rolling mill. The problem is to specify a method for altering width so that the length of a rolled out transition piece lying outside width tolerances can be reduced. Scrap losses are to be reduced. The crown of at least one working roll and/or at least one backing roll of a stand (7) is set as a function of a width error e=B−B between a setpoint width Bsetp and the width B of the rolled material (5), wherein the crown is increased when e>0 and the crown is reduced when e

摘要： The invention relates to a method, a computer program and a rolling mill train for cold rolling a metal strip (200). In order to achieve a shortening of undesired off-gauge lengths, the method according to the invention provides that the head (210) of the metal strip (200) already undergoes a thickness reduction at the first active rolling stand (n) in the rolling mill train, and then is transported on to the next rolling stand, in order to undergo a further thickness reduction there. The method according to the invention also provides for further reducing the initial pass thickness at the n-th rolling stand in accordance with the tensile stress that has built up in the meantime between the n+1-th and the n-th rolling stand.

摘要： A control apparatus of a rolling mill includes a load top/bottom distributor distributing loads as top and bottom side loads, a load top/bottom variation identification mechanism identifying load variation components occurring in connection with a rotational position of rolls from the top and bottom side loads, and top/bottom identified load variation storage storing, for each rotational position of rolls, top and bottom side variation components of the load in a kiss-roll condition identified by the load top/bottom variation identification mechanism. A manipulated variable computer computes a roll gap instruction value based on the top and bottom side variation components of the rolling load identified by the load top/bottom variation identification mechanism, and the top side variation component and the bottom side variation component of the load in a kiss-roll condition stored in the top/bottom identified load variation storage.
