Control Over the Innovative Pellet Production Process at TKOM No. 3 at PAO ‘Mikhailovskiy GOK’ Employing the State-of-the-Art Automated Process Control System

Abstract

The paper article describes the operating experience of a plant employing state-of-the-art production technology with an MOK-1-592 (TKOM no. 3) indurating machine started up in 2015 at PAO Mikhailovsky GOK. The technical and process solutions implemented in the design of a greenfield production complex is discussed, including a state-of-the-art automated process control system ensuring seamless operation of the equipment in the automated mode and improvement of the product quality. The innovative approach to the performance of the traveling-grate indurating machine and the equipment, which is a part of the heatflow diagram (thermal circuit) of the machine, is based on numerical simulation research of heat and weight transfer in an iron-ore pellet bed. Successful execution of the TKOM no. 3 project is a result of the researchbased and scientifically proven selection of control methods for the pellet production process, the use the state-of-the-industry algorithms for control over the operation modes of the entire production line.
