In order to solve the problem that a forge piece located at the position of the discharge port 2 is cooled quickly due to the fact that a furnace cavity is communicated with the outside after the furnace door at the position of the discharge port 2 is opened, a split type furnace door structure is specially designed on the integrated type furnace door. Referring to fig. 1 to 4, the split-type furnace door unit includes a plurality of furnace door single bodies 6, a sealing flange 7, a lifting cylinder 8 and a driving rod 9, the number of the furnace door single bodies 6 can be adjusted according to the size of the discharge port 2 of the heating furnace, and in this embodiment, a structural form of three furnace door single bodies 6 is adopted.
