The invention relates to a spinning oven. The spinning oven is characterized by comprising an inner oven body and an outer oven body, the end portion of the inner oven body and the end portion of the outer oven body share a bottom plate, a feeding port is formed in the part, at one end, of the bottom plate, and a discharging port is formed in the part, at the other end, of the bottom plate; a spiral heating pipe is arranged on the outer wall of the inner oven body; a steam inlet is formed in one end of the heating pipe, and a steam outlet is formed in the other end of the heating pipe; the feeding port and the steam outlet are located in the same end, and the discharging port and the steam inlet are located in the same end; and the part, at the discharging port end, of the bottom plate is further connected with an exhaust pipe communicating with the inner oven body, and the exhaust pipe is connected to the part, at the steam inlet end, of the heating pipe. According to the spinning oven, due to the fact that the exhaust pipe is connected between the part, at the steam inlet end, of the heating pipe and the inner oven body, water steam generated through drying of materials enters the heating pipe through the exhaust pipe, steam utilization is improved, and energy consumption is reduced; and heating can be more uniform through the spirally-arranged heating pipe.
