Abstract
Method for monitoring wear to cylinders of the cages of a rolling mill, in particular for bars or rods, including the following steps: reading by a neural network of a plurality of data relating to the initial conditions of one or more rolling cylinders, in particular one or more pairs of cylinders each belonging to a rolling cage, to the settings, and to the running of the process; and generation by the neural network of signals relating to the state of wear of the cylinders.

A method for monitoring wear to cylinders of mill stands of a rolling mill for bars or rods, comprising:
- reading, by a neural network, a plurality of data relating to:
- initial conditions of at least one rolling cylinder belonging to a corresponding rolling mill stand,
- settings, and
- a running of the process;
- and
- generating, by the neural network, signals relating to a state of wear of the rolling cylinders;
- wherein the neural network is trained with simulations at least one of:
- based on semiempirical models, and
- obtained with a finite elements method;
- and
- wherein the state of wear is evaluated as a linear value of a variation in depth of a runner in a preset point and a variation value of an area of a section of an exiting bar.
