Built around the numbers purchasing teams ask for first.
The final furnace length, muffle design, heating zones, strip accumulator capacity and cooling configuration are engineered around the customer’s material, strip gauge, line speed and plant envelope.
| Strip width | 850-1550 mm |
|---|---|
| Strip thickness | 0.1-3.0 mm |
| Annealing temperature | 750-1100°C |
| Product finish | BA / 2BA stainless steel strip |
| Protective atmosphere | Nitrogen, hydrogen, dissociated ammonia or argon |
Process Control
Temperature, dew point, atmosphere and energy data in one control layer.
AKS lines can use Siemens or Inovance PLC, touchscreen HMI, process data logging, fault alarms and real-time energy monitoring for production teams that need traceable furnace conditions.
- Heating-zone temperature accuracy up to ±2°C.
- Controlled atmosphere target below 10 ppm.
- Explosion protection, over-temperature alarm and power-loss protection.
Why Mills Compare AKS
Lower fuel use matters only when surface quality and uptime stay stable.
AKS positions its furnace lines around measurable production outcomes: gas consumption, flat strip shape, lower exit temperature, surface brightness and continuous equipment availability.
Saving 2-5 m³ of gas per tonne can translate into a 10-15% reduction in annual operating cost.
AKS ROI reference| Production factor | AKS reference | Typical market level |
|---|---|---|
| Output | 10-11 TV reference | 9-10 TV or lower |
| Gas consumption | 25-27 m³/t | 30+ m³/t |
| Flatness | No center wave or edge wave in target process window | Higher risk of center or edge wave |
| Cooling result | Lower exit temperature, bright white strip surface | Higher exit temperature, yellowing risk |
| Stability | High continuous operation target | Medium stability |
