[0036] Preferably, the absorption groove 21 is arranged in a U-shaped structure, with the opening end penetrating the upper edge of the limiting portion 2, so that during high-temperature working conditions, the container can prevent the limiting portion 2 from deforming after thermal expansion, causing extrusion of the intermediate material and damaging the shape of the limiting portion 2, while ensuring the overall strength of the limiting portion 2 and the service life of the container.

[0037] The specific number of absorption grooves 21 can be selected according to the shape and size of the material frame along the circumference of the limiting portion 2; the bearing part 1 and the limiting portion 2 have the same shape and can be designed as square or circular. When multiple absorption grooves 21 are provided, they are uniformly arranged in square or circular structures to ensure consistent deformation of the limiting portion 2. As an improvement, the bearing part 1 and the limiting portion 2 are integrally formed; further, the bearing part 1 and the limiting portion 2 are integrally cast.

[0038] Preferably, the bearing part 1 and the limiting portion 2 are made of stainless steel, specifically SUS310S.

[0039] Preferably, the bearing part 1 is provided with a plurality of positioning parts 11 for positioning materials, and the longitudinally adjacent positioning parts 11 are connected by a first reinforcing part 12, and the transversely adjacent positioning parts 11 are connected by a second reinforcing part 13.

[0043] In this embodiment, the inner contour of the positioning part 11 is also provided with a plurality of ventilation grooves 14. It should be noted that when the material is placed on the positioning part 11, the material abuts against the edge of the positioning part 11, making it difficult for the airflow to pass through and directly act on the surface of the material. By setting the ventilation grooves 14, the airflow can directly act on the surface of the material, thereby achieving efficient and high-quality material heating treatment.

[0044] In this embodiment, the ventilation groove 14 is preferably set at the intersection of the inner contour and the outer contour which has a polygonal structure. For example, two, four, or six grooves can be set. Of course, it is not limited to the above-mentioned setting position.

At the same time, the circular inner contour is particularly suitable for positioning spherical products, ensuring that the contact surface of the spherical product is in uniform contact with the inner contour, ensuring that the material is subjected to more uniform force during heating, and preventing the problem of excessive local stress in the material.

[0056] The second reinforcing portion 13 is at least one connecting rib connecting adjacent positioning portions 11. It should be noted that this embodiment preferably uses one connecting rib to connect adjacent positioning portions 11.

[0057] Of course, as shown in Figure 4 , this embodiment can also use two connecting ribs for the first reinforcing portion 12 and two connecting ribs for the second reinforcing portion 13.

[0063] In addition, the first weight reduction hole 15 cooperates with the push plate used to support the container to achieve the positioning connection between the container and the push plate.
