Abstract: A blank heating method for hot stamping is provided to minimize the thermal transformation of a blank by heating the blank in two stages using high frequency induction heating. A method for heating up a blank for hot stamping, used for the manufacture of the auto part like the car body and reinforcement part is characterized by passing a blank(11) for hot stamping, which is transferred by a transfer apparatus(1) at a fixed speed, successively through a first furnace(21) and a second furnace(31) in which respective high frequency induction heaters(22,32) are installed so that the blank is heated by the high frequency induction heating. The serving frequencies of high frequency induction heaters installed in the first furnace and the second furnace are differentiated so that the blank is heated through the two-stage induction heating.
