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.

This invention discloses a method for controlling the main steam temperature of an ultra-supercritical unit. An extraction valve is added to the extraction steam pipeline of the high-pressure heater to achieve precise extraction steam throttling adjustment. Thermodynamic parameters of the boiler and turbine systems are collected and cleaned. The feedwater heating insufficiency and reheat steam flow rate changes corresponding to the unit extraction steam throttling flow rate under different high-pressure heater extraction steam throttling schemes are calculated. Furthermore, the heat absorption changes of the economizer and part of the superheater heating surfaces after the reheater are calculated. Finally, the predicted value of the main steam temperature change corresponding to the unit extraction steam throttling flow rate under different high-pressure heater extraction steam throttling schemes is obtained. Based on the real-time deviation of the main steam temperature, the high-pressure heater extraction steam throttling scheme and the required extraction steam throttling flow rate are selected. By adjusting the extraction steam throttling flow rate of each high-pressure heater, more precise control of the main steam temperature is achieved, alleviating the problem of main steam overheating that easily occurs during rapid load increases. This is of great significance for improving the operational flexibility of ultra-supercritical units.
