Hot-rolled Carbon Steel Coil

The hot-rolled steel coil is made of continuous casting slab or pre-rolled slab as raw material, heated by a walking heating furnace, descaled by high-pressure water, and then entered into the rough rolling mill. Computer-controlled rolling, after final rolling, laminar cooling (computer-controlled cooling rate) and coiling by a coiler become straight rolls.

Hot-rolled coil is produced from semi-finished products , which are reduced to certain thicknesses by rolling and annealing and wound into a roll. Hot-rolled steel is used e.g. for the manufacture of pipes, steel doors and tanks or is further processed into cold-rolled steel.

Cold-rolled sheet in coil form is produced by removing rust from hot-rolled sheet by "pickling" it in a weak acid solution, then washing, brushing, drying, oiling and unrolling the sheet and finally performing cold-rolling by passing the sheet through a reducing mill under pressure and winding it into a roll. Cold-rolled steel is a more highly finished product and has a smoother surface, greater dimensional accuracy (thickness, width, length) and greater strength. Much cold-rolled steel is processed in the automotive industry, but some is also used in the manufacture of household goods.

◆ Production Process
Hot-rolled steel coil, produced from slabs (primarily continuous-cast slabs) heated and refined in roughing and finishing mills, undergoes a complex production process. In the final rolling mill, the hot steel strip is carefully cooled to a predetermined temperature before being rolled in a coiler to form the coil. These cooled and rolled coils then undergo various finishing processes, including flattening, straightening, cross-cutting or slitting, rigorous inspection, weighing, meticulous packaging, and labeling. Ultimately, they are processed into a variety of products, including steel plates, flat coils, and slit steel strip.
