Zusammenfassung:	The invention discloses a production method of titanium carbide slag for preparing titanium tetrachloride, and belongs to the field of metallurgy. The technical problem to be solved by the invention is to provide the production method of the titanium carbide slag for preparing the titanium tetrachloride by using a low-temperature chlorination process. The production method of the titanium carbideslag for preparing the titanium tetrachloride comprises the following steps: titanium-contained furnace slag is hot filled in an electric furnace in a molten state for heating to 1200-1500 DEG C; a carbon reducing agent is added for continuous heating to a temperature of not lower than 1500 DEG C; when the titanium dioxide conversion rate is not lower than 85%, and the content of titanium carbidein the furnace slag is 9-19%, a slag outlet of the electric furnace is opened; high-pressure water currents are used for water quenching of liquid-state slag in the slag outlet to obtain granular slag; and the granular slag is
