Push-Pull Pickling Line (PPPL)
The production process for metallic coated and organic coated steel begins with the pickling or cleaning of hot-rolled coils in order to remove the iron oxide scale which is formed during hot rolling of steel.
Hydrochloric acid is used for pickling, and the spent acid is regenerated in an acid regeneration plant and re-used making the whole process environmentally friendly.
After this process, the product is referred to as HRPO (“hot-rolled pickled and oiled”).
Cold Rolling Mill (CRM)
The Cold Rolling Mill reduces the thickness of HRPO coils to the required thickness, with the percentage reduction ranging from 50 – 90%. After this process, the product is referred to as “cold-rolled” or “full-hard steel”.
