PROCESS AND PLANT FOR PRODUCING TITANIUM SLAG FROM ILMENITE

摘要

A process for producing titanium slag from ilmenite comprises the steps of: a) Partial reduction of granular ilmenite with a reducing agent in a reduction reactor (6) at a temperature of at least 900°C, b) Transfer of the partially reduced hot ilmenite obtained in step a) into an electric furnace (12), c) Smelting the ilmenite in the electric furnace (12) in the presence of a reducing agent to form liquid pig iron and titanium slag, and d) Withdrawing the titanium slag from the electric furnace (12). The off gas of the reduction reactor (6) is introduced into a waste heat boiler (20).
