Title:
SINTERING PROCESS CONTROL METHOD, OPERATION GUIDANCE METHOD, SINTERED ORE MANUFACTURING METHOD, SINTERING PROCESS CONTROL DEVICE, OPERATION GUIDANCE DEVICE, SINTERING OPERATION GUIDANCE SYSTEM, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/053568
Kind Code:
A1
Abstract:
Provided is a sintering process control method which uses a physical model, which can calculate the state of a sintering process including a temperature distribution of a sintering raw material in the longitudinal direction and thickness direction in a sintering machine, to control the sintering process, wherein the sintering process control method comprises: a first prediction step (S2) for using the physical model to obtain first future predicted values of control variables when the current operation variables are maintained; and an operation amount calculation step (S5) for calculating an operation amount of a specific operation variable so as to reduce the difference between target values and overlapping predicted values of the control variables, which are based on the first predicted values and a step response when specific operation variables, which are a portion of the operation variables, are changed by a unit quantity.
