The base material for the Cold Rolling Mill is hot rolled coil with a thickness of 1.0 - 6.0 mm and a width of 800-1540 mm. As cold rolling and subsequent operations require a clean metallic surface, hot rolled coils pass a pickling line where hydrochloric acid treatment is applied in order to remove scale.

ARP-Acid Regeneration Plant. HCl Regeneration Systems or Acid Regeneration Plant (ARP) work together with pickling lines. By spray roasting method, waste pickle liquor(WPL) from pickling line is converted to ferric oxide(Fe 2 O 3)and gaseous hydrogen chloride(HCl), which would be absorbed by rinsing water from pickling line, thus hydrochloric acid of18%(wt) produced.
