Submerged Arc Furnace for Titanium Slag
High-Capacity Smelting Equipment by HANI Metallurgy
Efficiency and Precision in Titanium Metallurgy
The Submerged Arc Furnace for Titanium Slag is the core smelting equipment utilized in the enrichment of titanium dioxide from titaniferous ores. By maintaining a submerged arc state, where the electrode tips are buried deep within the charge, the SAF titanium slag unit ensures maximum heat transfer to the hearth while protecting the furnace cover from radiant heat. At HANI, we specialize in high-capacity smelting equipment that incorporates state-of-the-art automation and energy recovery systems. Our Submerged Arc Furnace for Titanium Slag is designed for high-throughput titanium smelting, enabling the efficient separation of metallic iron from the titania-rich slag phase.
Operating a Submerged Arc Furnace for Titanium Slag requires a deep understanding of slag mineralogy and electrical characteristics. HANI’s SAF titanium slag technology utilizes high-impedance transformers and precise electrode control logic to maintain a stable “crucible” in the hearth. As a world-class provider of smelting equipment, HANI provides turnkey solutions that include everything from raw material handling to final slag tapping. Our Submerged Arc Furnace for Titanium Slag has been optimized for low electrode consumption and high uptime, making it the preferred choice for major titanium producers globally.

Advanced Smelting Systems in HANI SAF
The HANI Submerged Arc Furnace for Titanium Slag incorporates several innovative technologies that set it apart from traditional smelting equipment. Our “Smart-Feed” technology ensures that the ilmenite ore and carbon reductant are distributed evenly, preventing the formation of “dead zones” in the SAF titanium slag hearth. This promotes uniform reduction and consistent slag quality.
Furthermore, our smelting equipment is equipped with high-temperature cameras and料面探测技术 (level detection technology) to monitor the furnace interior in real-time. This is particularly important for titanium smelting, where the foaming of slag can cause operational instabilities. By providing the operator with a digital twin of the Submerged Arc Furnace for Titanium Slag, HANI allows for proactive adjustments to the electrical and feed parameters.
Production Reference Values for SAF Titanium Slag
For the successful operation of a Submerged Arc Furnace for Titanium Slag, HANI provides the following operational benchmarks:
- Specific Power Consumption: 2100-2400 kWh per ton of slag produced in our smelting equipment.
- Electrode Consumption: 15-20 kg per ton of slag for the SAF titanium slag unit.
- Tapping Cycle: For a 33 MVA unit, tapping iron and slag every 3.5 to 4.5 hours ensures stable furnace pressure in titanium smelting.
Professional FAQ on SAF Smelting Equipment
Q1: How does the HANI Submerged Arc Furnace for Titanium Slag handle hazardous emissions?
A: Our smelting equipment is fully enclosed and connected to a high-temperature gas cleaning plant. This plant removes sulfur and particulates while cooling the gas for safety before atmospheric release from the SAF titanium slag facility.
Q2: What is the benefit of hot-charging in titanium smelting?
A: By charging pre-heated ilmenite (approx. 600-800°C) into the Submerged Arc Furnace for Titanium Slag, we reduce the electrical energy required for melting by 15-20%, significantly lowering the Opex of the smelting equipment.
Q3: How long does it take to install a HANI SAF titanium slag furnace?
A: A typical EPC project for a Submerged Arc Furnace for Titanium Slag takes 12 to 18 months from design to commissioning, depending on the site infrastructure and smelting equipment capacity.
