Method for controlling titanium carbide content with iron oxide powder
This disclosure relates to the field of titanium extraction technology from blast furnace slag, and particularly to a method for controlling the titanium carbide content using iron oxide powder, comprising the following steps: Step 1, when the slag generated by the carbon-blending of titanium-containing blast furnace slag reaches the smelting endpoint, a sample is taken to detect the mass percentage of titanium carbide in the slag; Step 2, when the mass percentage exceeds a set threshold, iron oxide powder is added to the slag to control the mass percentage within a reference range. This disclosure solves the problem of easy bending of titanium slabs with large aspect ratios during the upsetting process. This disclosure also solves the problem of high TiC content in existing titanium-containing blast furnace slag carbon-blending processes. By adding iron oxide powder to react with excess TiC in a directional manner, the TiC content can be stably controlled within a reference range, effectively reducing slag viscosity, ensuring smooth slag discharge, and avoiding safety hazards such as equipment blockage; at the same time, it improves the temperature control effect of the subsequent boiling chlorination reaction, and improves the efficiency and quality of subsequent titanium resource recovery.
