PURPOSE: A heating furnace is provided to prevent skid marks by a cam rotating unit on the underside of a material because a cam does not contact a material unless the camp rotating unit moves the material. CONSTITUTION: A heating furnace comprises a body(10) which heats a material inserted through an inlet hole, a transfer unit(100) which transfers the material to an outlet hole of the body, and a cam rotating unit(200) which is arranged between the transfer units and rotates to move the material. The transfer unit comprises a skid pipe part including a cooling path storing cooling water and a skid button part coupled to the skid pipe part and allowed to rotate. |
