The utility model relates to a cooling air reutilization device in a heat treatment slow cooling region, which has the effect that an air guide pipe is additionally arranged between the heat treatment slow cooling region and an oil removing region and is used for introducing hot air in the heat treatment slow cooling region into the oil removing region, so the hot air in the heat treatment slow cooling region is reutilized without waste, and meanwhile, the electricity consumption of an electric heater in the oil removing region is obviously reduced, and thus the goal of saving energy sources is reached.
