Pickling
The hot-rolled coil is passes through the pickling line, where hydrochloric acid solution is used to remove surface scale for its smooth surface finish before further processing.
Cold Rolling
Cold Rolling mill is of 6Hi Mill with 5 stand. Pickled coils are rolled in to the as normal as temperature(under of the re-crystallizing temperature) in the tandem cold rolled mills where they are processed into a specified thickness.
Electrolytic Cleaning
the main purpose of Electrolytic cleaning is to be remove in the lubricant oil and dirts left on the cold rolled strip before annealing.

Annealing
To obtain the desired grain structure and to improve the mechanical properties, the strip is passed through the (continuous annealing line) furnace, heating, soaking and cooling sections.
SPM
In order to improve the mechanical properties, suppress yield point elongation strip shape correction to secure the flat shape, is to be obtain desired roughness, the steel sheet should be passed through a skin pass mill.
Inspection
The equipment at the exit section are composed surface defect detector, Inspection table and oiler equipment. The products are inspected as well as judged systematically, and whether such products are appropriate to a client company or not.
