Silicon Carbon Alloy Case Study: Replacing FeSi & Recarburizer

Challenge at the East Asia Mill

The mill produced high-grade steel grades (e.g., HRB400, Q235) by adding ferrosilicon (for Si) plus recarburizer (for C) as two separate additions. The process was cumbersome and unstable.

Two separate alloy additions → longer furnace time, more labour

Inconsistent carbon/silicon recovery → off-grade chemistry, reworks

Fluctuating melt composition → frequent adjustments, higher energy use

Combined cost of FeSi + recarburizer kept rising

⚡ Performance that matters

✅ Si 65.85% (vs spec 65% min) ✅ C 17.12% (vs 15% min) ✅ Al 1.15% (low impurity) ✅ SGS certified

Step 1/6

HC Silicon Alloy Prepared

We sourced high-carbon silicon (Si 65% / C 15% grade) from our certified plant. Lumps are 10-60mm, homogenised and double-checked for consistency.

🔍 Client previous mix: FeSi (72% Si) + recarburizer (98% C)
📊 Our alloy composition: Si 65.85% · C 17.12% · Al 1.15%

Customer Approval & Reorder

After first trial, the mill reported stable carbon & silicon recovery, no off-grade heats, and 50% lower alloy cost. They switched entirely to our silicon carbon alloy and placed a repeat order.

“We eliminated two additions – now one alloy does the job. Chemistry is consistent, and our energy bill dropped.” – Steel Plant Metallurgist
