Title:
RAW MATERIAL CHARGING CONTROL DEVICE FOR BLAST FURNACE, METHOD FOR GENERATING OPENING DEGREE COMMAND VALUE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/100771
Kind Code:
A1
Abstract:
A raw material charging control device 90 comprises: a data collection unit 118 that accumulates, in a data storage unit, records for learning including the opening degree of a gate 40 for charging raw materials from a bunker 30 containing raw materials at the top of a blast furnace 2, the charging speed of raw materials from the bunker 30, and charging conditions which include characteristics of the raw materials; an off-line learning unit 211 that generates a prediction model representing the relationship between the opening degree, the charging speed, and the charging conditions by means of a multi-stage input-output relationship through machine learning based on a plurality of the records for learning stored in the data storage unit; a command generation unit 220 that generates an opening degree command value for the gate 40 corresponding to a charging target speed on the basis of the charging conditions of newly fed raw material, the charging target speed therefor, and the prediction model; and a gate 40 controller that causes the opening degree to correspond to the opening degree command value.
