Title:
ROLLING LINE MATERIAL PREDICTION AND MATERIAL CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2008/012881
Kind Code:
A1
Abstract:
A rolling line material prediction and material control apparatus for controlling the
material with high accuracy by having a function of simulating the variation course
of a process and complementing information to improve the prediction accuracy
of a material model. The apparatus has a rolling record information collecting
function of collecting rolling record information obtained from a sensor for
measuring the state of a hot rolling line and the state of a rolled steel sheet and
from the controller for controlling the hot rolling line, process information supplement
function for predicting process intermediate information representing the
intermediate state of the rolling line not collectable as rolling record information
on the basis of the rolling record information, fixed information such as the
machine dimensions, and target information such as on the thickness and width
of the rolled steel sheet, material prediction function for predicting the material
of the rolled steel sheet in synchronism with the progress of the rolling record
information and the process intermediate information on the basis of the rolling
record information and the process intermediate information, and material
control function of making a control so that the predicted material agrees with
the target one.
