This invention discloses a pit-type annealing furnace for forging, relating to the field of annealing furnace technology. It includes an annealing furnace body and a furnace cover. Support blocks are symmetrically fixed to the outer wall of the annealing furnace body, and positioning rods are rotatably connected to the top of the support blocks. In this pit-type annealing furnace for forging, during the feeding process, the furnace cover can be positioned by two positioning rods, allowing the storage cylinder to fall smoothly into the interior of the annealing furnace body, avoiding friction with the inner wall of the annealing furnace body or the heating liner. Furthermore, the frustum-shaped top of the positioning rods allows for better insertion into the positioning holes during hoisting to complete the material dropping. During annealing, a motor drives multiple sets of disturbance plates to push the material in the storage cylinder, allowing the placed material to move within the annealing furnace body, ensuring uniform heating of the material and guaranteeing efficient annealing.
