Process architecture
Line process map.
A BAL is a complete strip-processing route: entry, storage, controlled-atmosphere furnace, jet cooling and recoiling.
01 / ENTRY
Entry
Pay-off, centering, welding and tension preparation.
02 / STORAGE
Accumulator
Vertical or horizontal storage keeps the furnace running.
03 / HEAT
Furnace
Controlled-atmosphere heating for bright strip surface.
04 / COOL
Jet cooling
Airflow and temperature control support flatness.
05 / EXIT
Recoiling
Inspection, shearing, tension control and recoiling.
Engineering baseline
Built for BA strip.
AKS configures each line around strip size, grade, hardness target, atmosphere route and plant footprint.
| Material | 200, 300 and 400 series stainless steel by project review |
|---|---|
| Temperature | 750-1100°C configured process range |
| Atmosphere | Nitrogen, hydrogen, dissociated ammonia or argon |
| Automation | PLC, HMI, alarms, process logs and energy monitoring |
Operating case
What buyers compare.
Most projects are judged on output, fuel cost, strip shape, cooling result and uptime.
| Decision factor | AKS reference target | Typical market issue |
|---|---|---|
| Throughput | 10-11 t/h reference on matching projects | Speed, tension or cooling bottlenecks |
| Gas consumption | 23-27 m3/t reference range | 30+ m3/t when recovery is weak |
| Strip flatness | Lower center-wave and edge-wave risk | Uneven cooling or surface yellowing |
| Line availability | 24/7 operation and >98% target | Slowdowns increase cost per ton |
Business outcome
Control becomes margin.
Lower cost per ton, stable surface finish and fewer quality losses.
m3/t gas saving
Combustion tuning and heat recovery reduce fuel demand.
Capacity upside
Stable speed and fewer stops support larger coil programs.
Yield target
Temperature, atmosphere and cooling protect bright finish.
