MODELLING THE PROCESS OF FIRE-ROUNDING OF METALLIZED PELLETS TAKING INTO ACCOUNT THE PHYSICOCHEMICAL TRANSFORMATIONS OCCURRING IN THEM
Abstract
The problem of designing roasting machines and optimizing their thermal operation cannot be effectively solved until the intensities of individual chemical reactions are relatively accurately determined in the mathematical model of the process. Taking into account the comments made in the work on the overall complexity of the complex mathematical model of the roasting process of ore-coal pellets, it is desirable to formulate the description of the physicochemical aspects of the process in the form of relatively simple mathematical equations that nevertheless correctly reflect the main (characteristic) aspects of a particular phenomenon.
