There are substantial advantages to assembling integrated lines that combine the main process steps rolling, annealing and pickling (IRAPL) in a continuous production flow. The essential elements in the entry section are a pay-off-reel unit, a welding machine, and an entry strip accumulator. Next in line is a tandem mill in 6-high or 18-HS design with up to five stands, a strip cleaning section, another strip accumulator, an annealing furnace with cooling section, and a pickling section with strip accumulator. Finally, the exit end features strip finishing equipment such as a skin pass mill, tension leveler, creep looper, inline inspection area, tension reel, coil strapping, and coil weighing machine.
