PROBLEM TO BE SOLVED: To provide a method for conveying materials when a working beam type furnace for reheating or heat treating the materials is provided in a hot- working line and to improve the conveying ability. SOLUTION: A traverser 3 for disposing and returning the material in common is provided at a side of the hot-working line, and a roller conveyer type charging table 5 and extracting table 6 being provided at a charging port 6 and an extracting port 8, respectively, of the working beam type furnace 4 are each disposed so that the material conveying direction of each table becomes orthogonal with respect to the traverser 3 mentioned above. In the furnace 4, reciprocating stroke of movable beam is set so that odd number of material supporting positions can be obtained on the fixed beam 15, and the materials are arranged every one position on the fixed beam. Thereby, conveying of the material from an in-furnace charging table 20 to the fixed beam and conveying of the material from the fixed beam to an in-furnace extracting table 21 are alternately carried out every one reciprocating motion of the movable beam, and therefore it becomes possible to simultaneously charge the material into the furnace and extract the material from the furnace.
