[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] See also Figure 1 to Figure 4 The utility model provides a composite structure material pillow, which is a long strip material pillow body 1, and the material pillow body 1 is provided with a rack 11 for placing materials to be loaded into the furnace, and the rack 11 includes a plurality of first support frames 111 arranged at intervals along the length direction of the material pillow body 1, and a second support frame 112 is arranged between any two adjacent first support frames 111, and the height of the second support frame 112 is less than the height of the first support frame 111, so as to form a spatially dislocated structure and increase the loading capacity of the heat treatment. Specifically, the plurality of first support frames 111 and the second support frames 112 are arranged at equal intervals; the height difference between the first support frame 111 and the second support frame 112 is 90mm, and the first support frame 111 and the second support frame 112 can both support materials with a specification of φ30mm to 130mm.

[0028] In this embodiment, a first V-shaped groove 1111 for placing the material to be loaded is provided at the top of the first support frame 111 along the width direction of the pillow body 1, and a through hole is provided in the middle of the first support frame 111. It should be noted that the first V-shaped groove 1111 can stably position the material to be loaded on the first support frame 111, and is not easy to shake or roll, and the through hole is provided to reduce the weight of the pillow, improve the heat treatment effect of the material to be loaded, and save materials at the same time.
