Abstract
A system for calculating an output of a multi-stage forming process using a model of the forming process with which the output of the forming process is determined as a function of properties of the forming process. Selected properties of the forming process are determined using a neural network-based information processing arrangement.
Claims30
A system for calculating an output of a multi-stage forming process, comprising:
- a neural network-based information arrangement for determining properties of the multi-stage forming process;
- a processing arrangement including a model of the multi-stage forming process for determining the output of the multi-stage forming process as a function of selected ones of the properties of the multi-stage forming process;
- and
- a roll stand model for determining a first thickness profile of a rolled strip downstream from a roll stand as a function of a second thickness profile upstream from the roll stand and as a function of at least one of the properties of the roll stand and of the rolled stock, wherein selected ones of the properties of the roll stand and of the rolled stock are determined using the neural network-based information arrangement,
- wherein the first thickness profile of the rolled strip downstream from a first roll stand is used as the second thickness profile of the rolled strip upstream from a second roll stand, the second roll stand following the first roll stand.

A process for determining a first thickness profile of a rolled strip downstream from a roll stand, comprising the steps of:
- determining selected properties of at least one of the roll stand and the rolled strip using a neural network-based information processing arrangement;
- and
- using a roll stand model to determine the first thickness profile as a function of a second thickness profile upstream from the roll stand and as a function of the selected properties, the selected properties being at least one of the properties of the roll stand and of the rolled stock,
- wherein selected ones of the properties of the roll stand and of the rolled stock are determined using the neural network-based information arrangement,
- wherein the first thickness profile of the rolled strip downstream from a first roll stand is used as the second thickness profile of the rolled strip upstream from a second roll stand, the second roll stand following the first roll stand.
