Experience of Using the Integral Indicator of the Domain Charge in Selecting the Basic Mode of the Domain Melt

Abstract

To assess the quality of iron ore in selecting the blast-furnace charge, an integral characteristic of the batch is proposed. This index takes account of the mineralogical composition of the ore and the hightemperature properties of its components, which determine the final products. It is expedient to use the integral batch index in selecting the baseline operating conditions of the blast furnace in a time when the batch and technological conditions are varying. The use of the batch index as a measure of its fusibility is recommended in the analysis of melts and in optimization of the composition and properties of multicomponent blast-furnace batch.
