[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] The crossbeams 1 are arranged horizontally, with four crossbeams 1 divided into two groups arranged vertically and horizontally, each group having two crossbeams 1, and the two groups of crossbeams 1 are arranged vertically; the columns 2 are arranged vertically, with the four columns 2 arranged in an array; the crossbeams 1 and the columns 2 are alternately distributed along the circumference and fixedly connected to form a rectangular frame; the crossbeams 1 form the four sides of the rectangular frame; the columns 2 form the four corners of the rectangular frame, and are supported by the bottom ends of the columns 2, such as being supported on the ground; the rectangular frame formed by the crossbeams 1 and the columns 2 provides a mounting base for the L-shaped plate 3;

[0038] Each pair of L-shaped plates 3 is arranged opposite each other and spaced apart. Both ends of the L-shaped plates 3 are fixedly connected to the top surfaces of the two opposite beams 1. That is, the L-shaped plates 3 are arranged parallel to one set of beams 1 and both ends are fixedly connected to the top surface of the other set of parallel beams 1. A long strip trough for placing the alloy cake 5 is formed between each pair of L-shaped plates 3. The L-shaped plates 3 are of a bent structure and consist of a fixedly connected vertical plate and a bottom plate.

[0039] Multiple partitions 4 are spaced along the length of the L-shaped plates 3, separating each pair of L-shaped plates 3. Spaces for the alloy cakes 5 are formed between adjacent partitions 4. The partitions 4 divide the long trough into multiple spaces suitable for placing the alloy cakes 5, thereby limiting and supporting the alloy cakes 5. Both the L-shaped plates 3 and the partitions 4 can be made of a high-temperature resistant material with a melting point above 1400°C, such as molybdenum. The L-shaped plates 3 and the partitions 4 are connected by welding. The partitions 4 can be made of a 6mm thick flat plate.

[0040] The bottom plate extends toward the inside of each pair of L-shaped plates 3, that is, in each pair of L-shaped plates 3, the bottom plate of one L-shaped plate 3 extends horizontally toward one side of the other L-shaped plate 3, and the bottom plate forms the bottom support of the alloy cake 5; the height of the vertical plate is greater than the width of the bottom plate, so that the alloy cake 5 can be stably accommodated between the partitions 4.

[0041] In this embodiment, four pairs of L-shaped plates 3 are fixedly connected to the top surface of a pair of beams 1, and 34 partitions 4 are distributed between each pair of L-shaped plates 3. The 34 partitions 4 can form a storage space for 33 alloy cakes 5. Since four pairs of L-shaped plates 3 are provided, when a single-layer structure is adopted in this embodiment, 136 alloy cakes 5 can be accommodated.

[0042] like Figure 1 and Figure 2 As shown, the above-mentioned pallet can also include an ankle tube 6 fixedly connected to the bottom end of each column 2; the upper end of the ankle tube 6 is shaped and sleeved on the outer peripheral surface of the column 2; the ankle tube 6 can also be a square tube, and the inner side length of the square tube of the ankle tube 6 is greater than or equal to the outer side length of the square tube of the column 2, so that the ankle tube 6 can be sleeved on the outside of the column 2, thereby realizing the multi-layer structure of the pallet by the sleeve connection of the ankle tube 6 and the column 2, and the number of alloy cakes 5 subjected to one heat treatment can be multiplied by the setting of the ankle tube 6.

[0043] The pallet with the above structure can be loaded, unloaded and transported by forklift.

[0044] like Figure 1 and Figure 2 As shown, the pallet also includes multiple ribs 7 located on the bottom surface of the crossbeam 1. A rib 7 is fixedly connected to each of the columns 2 and the crossbeam 1 at their junctions, further enhancing the structural strength between the columns 2 and the crossbeam 1. The ribs 7 serve to strengthen the entire rectangular frame, partially supporting the crossbeam 1 and sharing some of its weight, thereby increasing the stability of the entire rectangular frame.

[0045] The above-mentioned tray is used for heat treatment in a gas quenching furnace. A rectangular frame is formed by fixedly connected columns 2 and beams 1. Multiple pairs of L-shaped plates 3 are fixedly connected to the top surface of the beam 1, and each pair of L-shaped plates 3 is divided into multiple accommodating spaces by multiple partitions 4. Multiple alloy cakes 5 can be positioned between the partitions 4 and the L-shaped plates 3. There is a certain gap between the partitions 4 and the cakes, and the alloy cakes 5 do not interfere with each other, so that the alloy cakes 5 can be easily taken out and put in, and multiple alloy cakes 5 can be placed at a time. Compared with the existing technology, the above-mentioned tray has the characteristics of easy placement and removal, convenient disassembly, simple operation, a large number of heat-treated alloy cakes 5, high heat treatment efficiency, and safety and reliability.

[0046] The above-mentioned pallet also includes an ankle tube 6 fixedly connected to the bottom end of each column 2. The ankle tube 6 can be used to position and stack the columns 2 at the four corners, which is convenient for stacking and removing the pallet, convenient for forklift insertion and removal, and convenient for disassembly. The number of alloy cakes 5 that need to be heat treated can be increased or decreased. The cakes are easy to load and unload and the operation is simple, which further improves the number of heat-treated alloy cakes 5 and the heat treatment efficiency.

[0047] In the above-mentioned tray, each pair of L-shaped plates 3 is arranged opposite to each other and at intervals, and there is a certain distance between each pair of L-shaped plates, so that after the alloy cake 5 is placed between the partitions 4, there is a gap at the bottom of the alloy cake 5. The inert gas used for cooling can enter between the partitions 4 from the bottom gap of the L-shaped plate 3, and the alloy cake 5 can be well cooled by the inert gas without dead corners, so that each alloy cake 5 can be well cooled, and the cooling effect is obvious and the cooling effect is good.

[0048] During the heat treatment process of the alloy cakes 5, the alloy cakes 5 are placed in a pallet and stacked with a forklift according to the number of heat-treated cakes. After the overall assembly is completed, a single-layer pallet or a multi-layer pallet is placed into the gas quenching furnace cavity by a forklift. According to the heat treatment time, a batch of alloy cakes 5 after heat treatment are taken out by a forklift.
