How To Melt Ferrotitanium Powder
Industrial Smelting Methods, Process Controls And Safety Guide | ZhenAn
Ferrotitanium powder
Ferrotitanium powder is widely used in steelmaking, alloy production, and titanium-bearing alloy modification. For steel plants and alloy manufacturers, correct melting and addition practice directly affects titanium recovery rate, inclusion control, and final alloy performance.
This technical guide explains how ferrotitanium powder is melted or introduced in industrial furnaces, including preparation steps, furnace routes, process controls, and operational precautions. It is written for steel mills, alloy producers, procurement managers, and plant decision makers evaluating titanium alloy additions.
What Is Ferrotitanium Powder Used for in Smelting Operations
Ferrotitanium powder (TiFe powder) is not typically melted alone like a base metal. In most industrial scenarios, it is:
Added into molten steel or alloy melts
Used as a titanium alloying additive
Applied as a deoxidizer and grain refiner
Introduced during refining or tapping stage
Its function is to deliver controlled titanium content efficiently into the melt.
Because titanium is highly reactive with oxygen and nitrogen, melting practice must emphasize atmosphere control and addition timing.
Common Furnace Routes for Using Ferrotitanium Powder
Different furnace types use different addition strategies.
Electric Arc Furnace (EAF)
Typical use characteristics:
Added during late melting or refining stage
Introduced after primary oxidation period
Often added with other ferroalloys
Works best with controlled slag conditions
Best for:
Alloy steel production
Structural steel with Ti control
Specialty steel grades
Ladle Furnace (LF) / Secondary Refining
This is one of the most efficient stages for ferrotitanium powder addition.
Advantages:
Better temperature stability
Lower oxygen activity
Easier composition trimming
Higher titanium recovery
Common practice:
Add after deoxidation
Combine with aluminum or silicon deoxidizers
Use staged feeding for accuracy
Induction Furnace
Used by specialty alloy and casting producers.
Key points:
Add in small batches
Ensure good stirring effect
Avoid surface oxidation
Prefer slightly coarser powder grades for controlled dissolution
Standard Industrial Melting / Addition Procedure
Preparation Before Melting
Before introducing ferrotitanium powder into a melt, operators should confirm:
Target titanium percentage in final alloy
Current bath chemistry
Furnace temperature range
Oxygen activity level
Slag condition
Material preparation checklist:
Verified ferrotitanium powder grade
Confirmed particle size range
Dry storage condition (no moisture)
Pre-weighed addition quantities
Clean addition tools and feeders
Typical Process Flow for Ferrotitanium Powder Addition
Step-by-step industrial practice:
Complete primary melting of base metal
Perform initial deoxidation (commonly Al or Si based)
Adjust slag to low oxidizing condition
Raise bath temperature to alloying range
Add ferrotitanium powder gradually (not all at once)
Maintain stirring or arc mixing
Hold for reaction and dissolution period
Take composition sample
Trim if necessary
Recommended Process Control Parameters
| Control Item | Typical Practice Range |
|---|---|
| Bath Temperature | 1550–1700°C (steel systems) |
| Addition Timing | After primary deoxidation |
| Atmosphere | Low oxygen / protected |
| Slag Condition | Low FeO preferred |
| Addition Mode | Gradual feeding |
| Hold Time | Depends on stirring efficiency |
Actual parameters vary by steel grade and furnace type.
Protection Atmosphere and Oxidation Control
Titanium has very strong oxygen affinity. Without control, titanium loss can be significant.
Atmosphere Control Measures
Use inert gas stirring (argon preferred)
Avoid oxidizing slag
Reduce air exposure during addition
Sub-surface feeding when possible
Why It Matters
Poor atmosphere control leads to:
Low titanium yield
Increased inclusions
Composition deviation
Higher alloy cost per ton
Particle Size Selection for Smelting Efficiency
Ferrotitanium powder particle size affects melting behavior and recovery.
| Particle Size | Behavior in Melt | Recommendation |
|---|---|---|
| Ultra-fine | Very fast reaction, higher oxidation risk | Injection systems |
| Fine powder | Fast dissolution | Ladle refining |
| Medium powder | Balanced behavior | General alloying |
| Fine granule | Slower but stable | Manual addition |

Operational Safety When Melting Ferrotitanium Powder
Handling and melting titanium-bearing powders requires strict safety discipline.
Key Safety Measures
Keep powder dry
Avoid open-air dumping into high-oxygen melts
Use protective equipment
Prevent dust accumulation
Use controlled feeding tools
Avoid moisture contact with hot metal
Powder + moisture + molten metal can cause violent reactions.
Quality Impact of Correct Ferrotitanium Powder Melting Practice
When properly added and controlled, ferrotitanium powder improves:
Grain size control
Strength and toughness
Wear resistance
Inclusion morphology
Alloy uniformity
Incorrect addition can reduce titanium recovery and increase defect risk.

Frequently Asked Questions About Ferrotitanium Powder Melting
Can ferrotitanium powder be melted alone?
In industrial practice, ferrotitanium powder is usually added into molten steel or alloy baths rather than melted alone. It acts as an alloy additive, not a base charge metal.
When is the best time to add ferrotitanium powder in steelmaking?
Typically after primary deoxidation and before final composition trimming, when oxygen activity is low.
Does ferrotitanium powder particle size affect titanium recovery?
Yes. Too fine may oxidize quickly; too coarse may dissolve slowly. Correct particle size improves titanium yield.
Is protection gas required when adding ferrotitanium powder?
In secondary refining, argon protection or stirring significantly improves alloy recovery and consistency.
How do I choose the right ferrotitanium powder grade for my furnace?
Selection depends on furnace type, steel grade, target Ti %, and feeding method. ZhenAn can recommend suitable ferrotitanium powder grades based on your process.
