FeSiZr

FeSiZr

Ferro Silicon Zirconium (FeSiZr) is a high-performance ferroalloy composed primarily of iron (Fe), silicon (Si), and zirconium (Zr). It is widely used as an efficient deoxidizer, grain refiner, and inclusion modifier in steelmaking, foundry production, and specialty alloy manufacturing. By combining the strong deoxidizing capability of silicon with the excellent refining performance of zirconium, FeSiZr effectively removes oxygen, sulfur, and nitrogen from molten steel while improving inclusion morphology and grain structure.

Key Features

FeSiZr with low aluminum content delivers superior deoxidation, grain refinement, and inclusion control, ensuring high‑quality steel and cast iron products.

 

Powerful Deoxidizer

Zirconium combines with oxygen, nitrogen, and sulfur, significantly reducing harmful inclusions and improving steel cleanliness.

 

Grain Refinement

Refines austenite and ferrite grains, boosting yield strength, impact toughness, and fatigue resistance.

 

Low Aluminum (<1.5%)

Minimizes aluminum oxide inclusions, reducing nozzle clogging and improving castability. Essential for clean steel grades.

 

Improved Casting Fluidity

In foundry applications, FeSiZr enhances fluidity, reduces porosity, and produces more uniform castings.

Frequently Asked Questions

Clear answers to the most common questions about our FeSiZr product.

1.What is Ferro Silicon Zirconium (FeSiZr)?

FeSiZr is a ferroalloy composed of iron, silicon, and zirconium. It is used as a deoxidizer, grain refiner, and alloy additive in steelmaking and foundry processes to improve mechanical properties and cleanliness.

2.Why is low aluminum important in FeSiZr?

Low aluminum content (<1.5%) reduces the formation of aluminum oxide inclusions, which can cause nozzle clogging during continuous casting and degrade steel surface quality. It is especially critical for clean steel and ultra‑low carbon grades.
3.What zirconium content grades are available?
We offer a wide range: Zr 10–18%, Zr 25%, Zr 30–35%, and Zr 35–40%. Higher Zr provides stronger grain refinement and deoxidation effects.
4.How does FeSiZr compare to standard ferrosilicon (FeSi)?
FeSiZr contains zirconium, which offers superior grain refinement, better control of nitrogen and sulfur, and more stable inclusion morphology compared to plain FeSi. It also enables lower aluminum usage.
5.In what forms can I order FeSiZr?
We supply FeSiZr in lump (10–50 mm, 10–100 mm), granule, powder (40–200 mesh), and briquette forms. Custom sizing is available.
6.What packaging options are there?
Standard packaging includes 25 kg woven bags with PE liner, 1 metric ton big bags, and steel drums. We can also customize packaging per your requirements.
7.Which quality standards do you meet?
Our FeSiZr complies with GB/T 5683, ASTM A673, JIS G2301, and DIN 17566. We provide mill test certificates and third‑party inspection upon request.
8.Can I get free samples?
Yes, free samples are available for quality evaluation. The buyer is responsible for shipping costs.
9.What is the typical lead time?
For stock items, lead time is 5–7 working days. For custom production, it is 15–20 working days after order confirmation and deposit.
10.What payment terms do you accept?
We accept T/T (Telegraphic Transfer) and L/C (Letter of Credit). Payment terms are negotiable for long‑term cooperation.
