Achieve higher efficiency, uniform heating, and lower emissions with Inductotherm’s IMZ® high-efficiency induction systems.
Combustion furnaces waste fuel and limit temperature precision. IMZ® Induction Reheating Systems replace gas-fired furnaces with an energy-efficient, fully electric solution that delivers precise temperature control, faster start-up, and cleaner operation.
Rolling Mills worldwide are improving yield, reducing scale formation, and achieving up to 98% system efficiency while cutting thousands of metric tons of CO₂ emissions each year.
the challenge
Combustion Furnaces Can’t Keep Up with Modern Production
Steel producers face increasing pressure to reduce fuel costs, improve throughput, and meet stricter emissions targets.
Gas-fired furnaces introduce inefficiencies—burner maintenance, long start-up times, scale loss, and inconsistent heat profiles—that reduce both productivity and profit.
the solution
IMZ®: High-Efficiency Induction Reheating
Inductotherm reheating systems use induction technology to deliver controlled, uniform heating directly within the steel billet or slab.
This means faster ramp-up, consistent temperature, and minimal heat loss.
Each system is engineered for your mill’s production rate and product size range - offering unmatched repeatability and integration with automated line control systems.
- Up to 98% total system efficiency
- Uniform temperature through billet cross-section
- Rapid start-up and shut-down
- Zero combustion gases (no CO₂, NOₓ, or SOₓ at point of use)
- Lower maintenance, higher uptime
Proven Results
Across the globe, IMZ® induction reheating systems are helping rolling mills achieve tangible results:
- Energy use reduced by 20–40% compared to gas furnaces
- Scale loss minimized by up to 1.5% of billet weight
- Annual CO₂ savings reaching hundreds of thousands of metric tons
- Improved yield and product consistency
