20090265146 | Method of Modeling the Time Gradient of the State of a Steel Volume by Means of a Computer and Corresponding Objects - A steel volume is modeled in a computer by means of a plurality of volume elements. The state of the steel volume at a given time comprises, for each volume element, characteristic quantities of an enthalpy existing at said time in the respective volume element and percentages, in which the steel is available in the respective volume element at the time in austenite, ferrite and cementite phases. For at least one volume element, the computer determines the time gradient of the characteristic quantities by resolving thermal conductivity and phase transition equations. One of the characteristic quantities is a locally invariable mean interstitial element concentration within the volume element in the austenite phase thereof. | 10-22-2009 |

20120318478 | METHOD FOR COOLING SHEET METAL BY MEANS OF A COOLING SECTION, COOLING SECTION AND CONTROL DEVICE FOR A COOLING SECTION - A method is provided for cooling sheet metal using a cooling section having multiple coolant dispensing devices for cooling upper and lower faces of a sheet metal. The cooling achieves a predefined target state of the sheet metal at a reference point at and/or after the exit from the cooling section, wherein coolant dispensing for a first and a second coolant dispensing device is determined, wherein the first and the second coolant dispensing devices are arranged opposite the sheet metal. Because the coolant dispensing for the first and second coolant dispensing devices is determined based on a predefined flow of heat to be dissipated from the sheet metal side that faces the respective coolant dispensing device, with a surface temperature of the respective sheet metal side being taken into account, the flatness of plate that is produced can be increased further with a simultaneously high throughput of the plate rolling train. | 12-20-2012 |
20130054003 | OPERATING METHOD FOR A PRODUCTION LINE WITH PREDICTION OF THE COMMAND SPEED - A method for a production line for rolling a strip may include: at a time point before a first strip point is fed into the production line, receiving for each of the first strip point, a number of second strip points, and a number of third strip points: (a) an actual value characteristic of an actual energy content and relates to a location in front of the production line and (a) a setpoint value characteristic of a setpoint energy content and relates to a location behind the production line; feeding the third strip points into the production line, followed by the first strip point, followed by the second strip points; prior to feeding the first strip point into the production line, determining a command variable for the first strip point and at least one second strip point based on a determining rule specific to the respective strip point, each command variable being characteristic of a command speed at which the production line is operated when the respective strip point is fed into the production line; wherein the determining rule for determining each respective command variable is determined based at least on (a) the actual value and the setpoint value of the respective strip point currently entering the production line, and (b) the actual value and the setpoint value of at least one strip point that has already entered the production line. | 02-28-2013 |
20140230511 | METHOD FOR CONTROLLING A HOT STRIP ROLLING LINE - A flat rolling stock of metal passes through roll stands of a finishing train, and a cooling section, in succession. Initial values which characterize the energy content of rolling stock points are determined, at the latest, when said rolling stock points enters into the finishing train. The rolling stock is tracked as it passes through the finishing train and cooling section. The initial values, trackings, and energy content influences are used to determine expected values for the energy content of the rolling stock. The energy content expected for a predetermined location, which lies between the first roll stand and the first cooling device of the cooling section is ascertained and used to determine a target energy content progression, from the predetermined location until the rolling stock passes out of the cooling section. The cooling devices are controlled based on the target energy content progression. | 08-21-2014 |
