Abstract
PURPOSE: To enable cold rolling without requiring annealing after pickling by a method wherein the lamellar spaces of pearlite in structures are kept in specified value being related to the content of carbon and thickness of a high carbon hot rolled steel band for cold-finished special hoop when manufacturing the steel band.
CONSTITUTION: The continuously casted slab of high carbon steel is heated at 1,250°C, hot-rolled at 850W870°C finishing temperatures and wound to a coil at 520W750°C winding temperatures. The lamellar spaces of pearlite in the structures of a hot rolled steel plate are kept so as to satisfy the formula by properly controlling the winding temperatures as mentioned above. The hot rolled steel plate manufactured under this condition is cold-rolled without annealing, and can be rolled to a cold rolled steel band without forming defects such as the cracks at lugs, etc.
