APPARATUS AND METHOD FOR HEATING ROLLING MATERIAL

摘要

According to an embodiment of the present invention, a method for heating a rolling material comprises: a calculation step of calculating zero time which is time when a rolling material moving in one direction is positioned in an internal space of a heating furnace; and a control step of adjusting an internal temperature and an oxygen concentration of the internal space according to the zero time calculated in the zero time calculation step to adjust a scale thickness of the rolling material to a prescribed value or lower.
