Titanium Slag Smelting Furnace
High-Purity Titanium Slag Production by HANI Metallurgy
Advancing the Frontiers of Titanium Metallurgy
The Titanium Slag Smelting Furnace is an essential unit in the industrial chain of titanium metal and titanium dioxide (TiO2) production. As a specialized Titanium Slag Furnace, it is used for the high-temperature melting and reduction of ilmenite ore to produce high-titania slag and pig iron byproducts. At HANI, we have mastered the full-process design of titanium smelting, integrating hot-charging and hot-delivery technologies to achieve record-low energy consumption and maximum production capacity. Our SAF for titanium slag represents the pinnacle of modern metallurgical engineering, featuring fully enclosed designs and advanced gas purification systems.
A HANI Titanium Slag Smelting Furnace is designed to handle the extremely corrosive nature of titanium slag while maintaining high thermal efficiency. The furnace uses the most advanced refractory lining technology, ensuring a service life of 7 to 10 years even under harsh operating conditions. By utilizing a high-intensity electric arc, the Titanium Slag Furnace facilitates the separation of metallic iron from the enriched titanium slag, a process that is critical for the subsequent chloride or sulfate titanium dioxide manufacturing routes. Our SAF for titanium slag and titanium smelting solutions are trusted by industry leaders for their reliability and automated operation.

Chemical Process of Titanium Slag Production
The production of titanium slag in a Titanium Slag Smelting Furnace is based on the carbothermic reduction of iron oxides in ilmenite (FeTiO3) without reducing the titanium dioxide. The goal is to separate iron into a metallic phase while enriching TiO2 in the slag phase. HANI’s titanium smelting technology optimizes this selective reduction by controlling the carbon dosage and temperature (typically 1600-1750°C).
Thermodynamic Reactions in SAF for Titanium Slag:
1. FeTiO3 + C → Fe + TiO2 + CO (Selective Reduction)
2. FeO + C → Fe + CO
3. TiO2 + C → TiOxCy + CO (Undesired Over-reduction)
Precise control in the Titanium Slag Furnace is vital to prevent the formation of titanium carbides or nitrides, which increase slag viscosity and complicate the tapping process. HANI‘s AI-integrated control system manages the power-to-feed ratio in the SAF for titanium slag, ensuring that the titanium smelting reaction proceeds at the optimal thermodynamic window.
