Beam mechanism of continuous heating furnace steel inlet

The utility model discloses a beam mechanism of a continuous heating furnace steel inlet. The beam mechanism is characterized by comprising a cast beam and a circulating pipe horizontally arranged inside the beam, wherein one end of the circulating pipe is connected with a lower water pipe, and the other end of the circulating pipe is connected with an upper steam pipe; a layer of asphalt is coated on the outer wall of the circulating pipe; the upper steam pipe and the lower water pipe are both connected with a steam pocket. The cast beam is internally provided with the circulating pipe to be connected with a gasification circulation system of a heating furnace and communicated with the steam pocket, the beam is fixedly connected with an I-shaped beam of a furnace body through a tie bar, and the asphalt is coated on the outer walls of the circulating pipe and the tie bar, so that the thermal expansion relationship among the insides of the circulating pipe, the tie bar and the cast beam is ensured, the strengt
