- Abstract
After blanking and bending to form parts with the desired shape, high-carbon steels are quenched and tempered to produce various machine parts. Thus, the spheroidization, formability and hardenability are very important properties for high-carbon steels. Thermo-Mechanical control Process of rolling has been widely used in the steel industry. However, it is difficult to apply this process to high-carbon steels because of the heavy rolling load. Thus, fine-grained high-carbon hot strips were developed through high-reduction and low-temperature rolling by using single roll rolling mills with different diameters and laminar flow cooling devices in the finishing train, the grain size of these steels was about 3 microns. Also developed annealed strips with fine homogeneously dispersed spheroidal cementite had many excellent characteristics. For example, burring formability investigated by the hole-expanding and surface hardness evaluated by laser hardening of the developed high-carbon annealed steels, were excellent.
