Investigation of thermal properties of charged materials for ferroalloy with titanium by the carbothermal method smelting

Abstract

This paper presents the results of studies of the thermal properties for charge materials investigated for the smelting of a ferroalloy with titanium by the carbothermal method. The following charge materials were involved and studied in the work: ilmenite concentrate from the Shokash deposit (Aktobe region, Martuk district), high-ash coals, indispensable for domestic purposes for their intended purpose. Derivatographic analysis was used to study the thermal properties of the charge. To compare the electrical resistance of coals in order to select an effective reducing agent, in this work, measurements of the electrical resistance of high-ash coals from the Saryadyr, Borly and Ekibastuz deposit were carried out. As a result, it was found that for the smelting of a new complex titanium-containing ferroalloy, high-ash coal from the Saryadyr deposit is most applicable.
