This article provides an analysis of the effect of adding hot-briquetted iron (HBI) on the main smelting production indices, DSP-150 lining working layer life, and refractory material consumption for servicing under PAO Tagmet electric steel smelting workshop conditions. Various schemes are considered for HBI charge fractions to a furnace and the optimum version is determined. Changes in slag composition are analyzed with use of HBI. Recommendations are proposed for furnace lining servicing under conditions of using HBI on the example of DSP-150 operated on a solid charge in order to improve its life. The economic saving effect of introducing the recommendations is demonstrated.
