Stacked material frame for annealing furnace

The utility model discloses a stacked material frame for an annealing furnace. The stacked material frame comprises a round frame body and a frame bottom integrally formed, wherein a spiral telescopic belt is arranged on the circumference surface of the frame body, and is formed by more than two slots arranged at intervals; a pipy central shaft is arranged in the center of the frame bottom; a cross beam connected with the frame body extends from the periphery of the top part of the central shaft. Through adopting the central shaft and the beam structure on the periphery of the top part of the central shaft and combining the spiral telescopic belt structure, the deformation allowance of a material frame during the thermal deformation in the annealing furnace is larger, emergence of cracks is prevented, two layers of material frames can be placed in an up-and-down stacked manner, the product in the lower layer of material frame is effectively prevented from being squashed by the frame bottom of the upper layer
