Continuous casting slab or slab slab is used as raw material, heated by step heating furnace, dewatered by high pressure water and then into rough rolling mill. The rough rolling material is cut into the tail and tail, and then enters the finishing mill to carry out computer controlled rolling. After the final rolling, it is subjected to laminar cooling (computer controlled cooling rate) and the coiler is taken up to become a straight hair roll. The head and tail of the straight hair roll are often in the shape of a tongue and a fishtail. The thickness and width are inferior in accuracy, and the side has frequent defects such as a wave shape, a folded edge, and a tower shape. The weight of the coil is heavier and the inner diameter of the coil is 760 mm.
After straightening the straight hair through the cutting, cutting, trimming and multi-pass straightening, leveling and other finishing lines, and then cutting or rewinding, it becomes: hot-rolled steel sheet, flat hot-rolled steel coil, vertical Cutting tape and other products. If the hot-rolled finishing rolls are pickled to remove scale and oiled, they are hot-rolled pickled rolls. This product has a tendency to partially replace cold-rolled sheets, and the price is moderate, which is very popular among users.
