Application of artificial neural network for determination of the additives amount in the automated process control system of steelmaking in basic oxygen furnace

Abstract

This paper describes an algorithm of determining the amount of deoxidizing and alloying

materials that are loaded into the basic oxygen furnace (BOF) and steel ladle on the base

of information about burdening of melting and chemical composition of the steel using

artificial neural network (ANN). The analysis of resent researches and publications regarding

mathematical modeling of BOF melting and application of ANN as such models

was made. This analysis show that selected topic has novelty and relevance. The schematic

of interaction of different kinds of mathematical models in the system of automated

control of BOF melting is offered. The research of applicability of artificial neural networks

for determination of quantity of deoxidizing and alloying components is performed.

The place of the obtained artificial neural network in the overall system of automated

control of basic oxygen melting is described. The description of the multistep selection

process of the ANN architecture is given. The correlation coefficients and mean square

deviations for all parameters are found. The results of performed analysis are considered

satisfactory. The recommendations for replacement of alloying and deoxidizing components

in the absence of any of them in stock are given.
