Ferro Silicon Barium Mold Powder (Ba 2-3%) – Product Overview
Ferro Silicon Barium (FeSiBa) mold powder with Ba 2-3% is a high-performance alloy powder engineered for demanding continuous casting operations. The increased barium content (2-3%) provides superior fluxing action, resulting in exceptionally fluid slags that enhance mold lubrication, reduce friction, and improve heat transfer uniformity. This grade is particularly effective for high-speed casters and steels sensitive to surface defects.
Product Core Advantages
- Elevated Barium (2-3%): Delivers maximum slag fluidity, ideal for high-speed casting and complex steel grades.
- Ultra-Low Impurities: Al ≤1.5% minimizes alumina cluster formation, maintaining consistent slag properties.
- Fully Customizable Sizing: From ultrafine powder to precise granules, we tailor to your mold flux production line.
- Rigorous Quality Control: Every batch analyzed in our accredited lab; full traceability.
- Flexible Formulation: We can fine-tune Ba, Ca, or Si content to match your exact flux design.
Typical Application Areas
- High-Speed Continuous Casting Mold Fluxes: Primary raw material for fluxes used in slab, bloom, and billet casters operating at >1.5 m/min.
- Specialty Steel Refining: Enhances inclusion modification in bearing steels, tire cord, and other critical grades.
- Inoculant for High-Ductility Irons: Provides prolonged inoculation effect, improving nodularity in heavy-section castings.
- Welding Fluxes & Coatings: Used in agglomerated fluxes for submerged arc welding.

Application Guidelines – FeSiBa Mold Powder (Ba 2-3%)
High-Performance Mold Fluxes
With Ba 2-3%, this grade is tailored for fluxes requiring very low melting point and high lubrication. It is especially effective in preventing sticker breakouts during high-speed casting of peritectic or cracking-sensitive steels.
Refining & Inclusion Engineering
In secondary metallurgy, the higher barium content enhances the modification of spinel and alumina inclusions, improving steel cleanliness and castability.
Inoculation of Heavy-Section Castings
The prolonged inoculation effect of barium (2-3%) helps maintain nodularity in thick-walled ductile iron castings, reducing chill and ferrite halo.
Typical Addition Rates
For mold fluxes: 7-20% of the blend depending on target properties. For ladle treatment: 1.5-4 kg/t. Contact us for detailed blending recommendations.

Frequently Asked Questions – FeSiBa Mold Powder (Ba 2-3%)
Is it possible to entrust a third-party inspection to check the quality before shipment?
+
Certainly, we support third-party inspections by internationally recognized quality inspection agencies such as SGS and BV to verify product quality before shipment. The inspection covers product appearance, weighing, dimensions, and chemical composition analysis. The entire inspection process will be documented with photos and written records, which will be provided to you together with the final inspection report. This ensures you have no concerns regarding product quality.
When should I choose Ba 2-3% instead of Ba 1-2%?+
Choose Ba 2-3% when you need maximum slag fluidity, e.g., for high-speed casting (>1.5 m/min), thin slab casters, or steels with high cracking tendency. It provides extra lubrication and heat transfer control.
Can you supply this grade as per my specific particle size?+
Yes, we specialize in custom sizing. Whether you need a narrow mesh cut or a specific D50, we can produce it.
Does higher barium affect slag viscosity stability?+
Properly formulated, Ba 2-3% maintains stable viscosity while lowering the melting point. We recommend lab-scale trials to optimize your flux recipe.
Is a certificate of analysis included?+
Absolutely. Each batch is analyzed, and a detailed COA is provided.
What quality standards do you follow?+
We comply with GB/T 3282, ASTM A1025, and our internal ISO 9001 certified processes.
