Abstract

PURPOSE: To manufacture a high-strength steel strip of a high carbon steel by externally heating edge parts alone of a steel strip to a specified temp. range to carry out local patenting before cold rolling or during several cold rolling processes.
CONSTITUTION: A high carbon steel strip is provided with a fine pearlite structure or a sorbite structure by controlled cooling or patenting after hot rolling, and this strip is cold rolled to obtain a steel strip having a developed fibrous structure. At this time, before the cold rolling or during several cold rolling processes edge parts alone of the strip are externally heated to 800W950°C to carry out local patenting. Laser heating, high-frequency induction heating or gas flame heating is applied as the external heating.
