• a cooling unit provided in the apparatus body to supply a cooling fluid,
• wherein the apparatus body comprises:
• a first edge body facing a first edge portion extending from one side end of the steel sheet by a predetermined distance in a center direction of the steel sheet;
• and
• a second edge body facing a second edge portion extending from the other side end of the steel sheet by a predetermined distance in the center direction of the steel sheet, and
• wherein each of the first and second edge bodies is provided such that a cross-section in a direction, perpendicular to a conveying direction of the steel sheet, is linearly inclined, and end portions of the first and second edge bodies are inclined in a direction away from the steel sheet to be present farthest from the steel sheet.
