METHODOLOGY FOR ANALYZING MICROELEMENT BEHAVIOR IN BLAST FURNACE SMELTING

摘要

Methodology for analyzing and predicting the behavior of microelements in blast furnace smelting is developed, taking account of process features, the form of microelements present in metallurgical materials, and the method of their introduction into a blast furnace. The procedure includes experimental, research, and calculation sections. As a result of comparing experimental data and the results of modelling, element distribution between pig iron, slag, and the gas phase of the blast furnace process is determined. It is established that the increase observed recently in the microelement content in blastfurnace sludge is mainly connected with features of the behavior of the proportion of these microelements within the composition of the organic part of coke and coal dust fuel.
