Hot-rolled coils are made from slabs, which are heated and then rolled into strips by rough rolling mills and finishing rolling mills. The high-temperature steel strip coming out of the finishing mill is cooled to the set temperature by laminar flow and wound into a coil by a coiler. Finishing lines for steel plate, flat coil and slitting strip products (leveling, straightening, cross-cutting or slitting, inspection, weighing, packing and marking, etc.).
