What is ferrotitanium used for?
Ferrotitanium is a titanium-iron master alloy used primarily to:
Deoxidize steel: Removes oxygen/nitrogen (superior to aluminum/silicon) for cleaner, inclusion-free steel.
Grain refinement: Adds 0.01–0.25% Ti to control austenite grain growth in HSLA steels (e.g., automotive sheets).
Stabilize stainless steel: Fixes carbon as TiC to prevent chromium depletion (grades 321, 316Ti).
Produce titanium alloys: Feedstock for Ti-6Al-4V (via vacuum arc remelting).
Welding electrodes: Enhances arc stability and weld metal strength.
Aerospace/defense: Critical for jet engine alloys (Ti weight savings = 45% vs. steel).
As an additive: FeTi itself is not structural; it imparts strength to host materials:
Boosts steel yield strength by 15–30% via grain refinement/precipitation hardening.
Enables titanium alloys with tensile strengths up to 1,000–1,200 MPa (e.g., Ti-6Al-4V).
Intrinsic properties:
Hardness: 200–250 HB (high-Ti grades).
Melting point: ~1,400°C (eases dissolution in steel).
What is the composition of ferrotitanium?
Standard grades defined by Ti content and key residuals:
| Grade | Ti (%) | Al (%) | Si (%) | C (%) | O (%) | Primary Use |
|---|---|---|---|---|---|---|
| FeTi30 | 25–35% | ≤8.0 | ≤4.0 | ≤0.15 | ≤0.4 | Steel deoxidation |
| FeTi40 | 35–45% | ≤8.5 | ≤4.5 | ≤0.15 | ≤0.4 | Stainless steel |
| FeTi70 | 65–75% | ≤0.5 | ≤0.1 | ≤0.05 | ≤0.15 | Titanium alloys |
Key impurities: Low oxygen/nitrogen critical for aerospace grades.
Two primary methods:
A. Aluminothermic Reduction (High-Purity FeTi70)
Raw materials: Ilmenite (FeTiO₃)/rutile (TiO₂) + iron oxide/Fe scrap + aluminum powder.
Reaction:3\text{TiO}_2 + 4\text{Al} \rightarrow 3\text{Ti} + 2\text{Al}_2\text{O}_3 + \text{Heat (2,200°C)}3TiO2+4Al→3Ti+2Al2O3+Heat (2,200°C)
Process:
Ignited in a refractory-lined reactor → exothermic reaction melts alloy.
FeTi sinks below Al₂O₃ slag.
Output: 70% Ti, low residuals.
B. Electric Arc Furnace (EAF) Smelting (FeTi30/40)
Raw materials: Titanium scrap/sponge + iron.
Process:
Charged into EAF under argon.
Melted at 1,500–1,600°C.
Refined to remove O/N.
Output: 30–45% Ti, higher residuals.
