Rathi Steel skips the furnace in a hot-charging trial at Ghaziabad
Billets went straight from the caster to the TMT mill, cutting a fuel-heavy step. The company has previously estimated this saves ₹3,000-4,000 per ton.
— 1 earlier story on Rathi Steel & Power Ltd. →What's new
- Rathi completed a hot-charging trial, sending billets directly from the continuous caster to its TMT bar mill.
- The trial successfully produced high-strength, seismic-resistant Fe 550D grade rebars.
- The process cuts fuel consumption and scale loss, which the company says lowers production costs and carbon emissions.
Why this matters
The trial eliminates a costly reheating step. For a nano-cap steelmaker, the prior guidance of ₹3,000-4,000 per ton in savings is a material margin lever. The proof of concept is now established at its plant.
What we're watching
- Whether hot charging moves from a successful trial to standard, continuous operation.
- The actual, verified cost savings per ton once running at scale.
- Any customer orders secured for the Fe 550D rebars produced this way.
The full read
Rathi Steel has moved billets straight from the continuous caster to its TMT mill in a hot-charging trial at Ghaziabad. The process eliminates a reheating step, cutting fuel use and scale loss. The trial produced Fe 550D grade rebars, a high-strength product used in seismic-resistant construction. The company has previously cited direct-charging savings of ₹3,000-4,000 per ton. That figure matters. For a nano-cap steelmaker, it represents a direct hit to the cost base. The trial proves the technology works at Rathi's plant. The open question is whether it can be sustained continuously, and what the real, per-ton savings will be once the process runs at scale. Not yet. Hardly a done deal. But the first box is ticked.
Questions answered
- What is hot charging, and why does it save money?
- Hot charging moves billets from the casting machine to the rolling mill while still hot. It skips the reheating furnace, which cuts fuel consumption and reduces metal lost as scale.
- What product came out of the trial?
- The trial produced Fe 550D grade TMT rebars, a high-strength product with seismic resistance used in infrastructure projects.
- How much could this save Rathi per ton?
- The company has previously cited direct-charging savings of ₹3,000-4,000 per ton. This filing does not report the actual savings from this specific trial.
- Is this now the permanent process at the Ghaziabad plant?
- The filing describes a completed trial run. Rathi has not stated whether hot charging will become the standard operating method.
