Ferro Silicon Barium Mold Powder (Ba 1-2%) – Product Overview
Ferro Silicon Barium (FeSiBa) mold powder with Ba 1-2% is a specially formulated alloy powder used primarily in the production of mold fluxes for continuous casting of steel. It combines the deoxidizing power of silicon with the surface-active properties of barium, resulting in improved slag lubrication, controlled heat transfer, and better slab surface quality. Our production process ensures uniform particle size distribution and consistent chemistry.
Product Core Advantages
- Optimized Barium Content (1-2%): Barium enhances slag fluidity and melting rate, reducing casting defects like sticker breakouts.
- Low Aluminum & Impurities: Al ≤1.5% minimizes alumina buildup in the slag, maintaining stable viscosity.
- Custom Particle Sizing: Available in fine powders (0-2mm, 0-1mm) or specific mesh sizes to match your mold powder blending requirements.
- Consistent Quality: Produced in submerged arc furnaces with strict raw material selection and quality control.
- Customizable Formulations: We can adjust Ba, Ca, or Si content to meet your exact mold flux design.
Typical Application Areas
- Continuous Casting Mold Fluxes: Primary raw material to produce granular or powdered mold fluxes for slab, bloom, and billet casters.
- Steel Refining: Used as a slag conditioner to improve desulfurization and inclusion absorption.
- Inoculant for Cast Iron: Enhances graphite morphology and mechanical properties in ductile and gray iron.
- Welding Electrode Coatings: Provides deoxidation and arc stability in certain flux formulations.

Application Guidelines – FeSiBa Mold Powder (Ba 1-2%)
Mold Flux Production
FeSiBa with Ba 1-2% is a key component in synthetic mold fluxes for continuous casting. Barium acts as a fluxing agent, lowering the melting point of the slag and improving its lubricating properties. Typical addition rates in flux blends range from 5% to 15%, depending on the desired basicity and viscosity.
Steel Refining
In ladle metallurgy, FeSiBa powder helps modify inclusions and improve steel cleanliness. The barium enhances the absorption of Al₂O₃ inclusions, reducing clogging in the tundish and nozzle.
Inoculation of Cast Iron
Used as an inoculant in ductile iron production, the barium provides longer-lasting inoculation effect, reducing chill and improving nodule count.
Typical Addition Rates
For mold flux formulations: 5-15% of the total blend. For ladle slag conditioning: 1-3 kg per ton of steel. Our technical team can assist with optimal sizing and blending recommendations.

Frequently Asked Questions – FeSiBa Mold Powder (Ba 1-2%)
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.
What is the role of barium in mold powder?+
Barium lowers the melting point of the slag, improves lubrication between strand and mold, and helps absorb non-metallic inclusions. Ba 1-2% offers a balanced performance for most steel grades.
Can you supply custom particle sizes for my specific flux recipe?+
Absolutely. We can produce any mesh size or particle distribution, from fine powder to coarse granules, and we frequently adjust to customer specifications.
Is this product suitable for high-speed continuous casting?+
Yes, the Ba 1-2% grade provides the right fluidity for high-speed casters. For extremely high speeds, we might recommend the Ba 2-3% variant, but this grade is a versatile workhorse.
Do you provide a certificate of analysis?+
Yes, every batch is tested (ISO 17025 lab) and a COA with Si, Ba, Ca, Al, etc. is provided.
What is your production capacity for FeSiBa?+
We produce over 15,000 metric tons annually of FeSiBa alloys, ensuring stable supply.
