Use of statistical analyze for calculation of specific slag heat of "Trepca" shaft furnace

In shaft furnace of metallurgic complex in "Trepca", during the agglomerate melting, gained slag consist plenty of components as are: Ph, ZnO, CaO, Fe, SiO2, S etc. values of content components have impacts in values of specific heat of slag. Handling of this problematic requires one statistical approach, using data from 465 laboratory measurements annually. According to the proper statistical model are made calculation of statistical distribution and dispersion characteristics of,,spreading for components of slag that are used for calculation of specific heats of slag components. Gained results are important data for thermal calculation of shaft furnace, pre-furnace or electric furnace for using of slag components from technologic process.
