[0015] Figure 1 It is a schematic diagram of the structure of at least one embodiment of the utility model;

[0016] Figure 2 yes Figure 1 Bottom view of .

[0017] In the figure: 1-box plate, 2-column, 3-support member, 4-top plate, 5-bottom plate. DETAILED DESCRIPTION

[0018] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0019] The first embodiment of the present invention relates to Figure 1 , Figure 2 The furnace core structure of a box-type graphitization furnace shown in the figure comprises a box plate 1; the box plate 1 is installed between a top plate 4 and a bottom plate 5 in a plurality of longitudinal parallel strips evenly distributed, and transverse support members 3 are installed in the middle and ends of the box plate 1.

[0020] When in use, the negative electrode material that needs high temperature treatment is placed in a box body composed of box plates. After power is turned on, the current first passes through the box plate 1 and causes it to heat up. The temperature will gradually increase until it reaches the graphitization temperature of the negative electrode material. As a result, the filling rate of the negative electrode product can be greatly improved.

[0021] The second embodiment of the present invention is substantially the same as the first embodiment, mainly in that a column 2 is provided in the middle of the box board 1 .

[0022] Furthermore, the support member 3 is a transverse box board at the end of the box board 1 and is a support strip in the middle of the box board 1 .

[0023] Furthermore, the support bar is connected to the column 2 through the groove, thereby forming a stable box structure.

[0024] The third embodiment of the utility model is roughly the same as the first embodiment, mainly in that the bottom plate 5 is a multi-strip structure, each of which is located between two box plates 1. The function of the bottom plate 5 is to separate the insulation material at the bottom of the furnace core from the product. Generally, there are two ways of arrangement. One is to fully spread the bottom plate. According to the size and feasibility of production, the bottom plate can be made in blocks and then spliced. The overall structure of the bottom plate made in this way is complete; the other is that the bottom of the "grid" surrounded by each box plate can be made into a separate bottom plate. The advantage of this is that the bottom plate is "floating", which can effectively offset the volume changes of the insulation material and the product during the heating process. It is easy to see that the first way of fully spreading the bottom plate is a common way, and the second way is this embodiment.

[0025] The fourth embodiment of the utility model is substantially the same as the first embodiment, mainly in that the top plate 4 is smaller than the box body surrounded by the box plate 1 and the support member 3, and the top plate 4 is non-fixedly placed on the box body surrounded by the box plate 1 and the support member 3. During production, the box body is filled with negative electrode products, and the top plate is placed on top. During the production process, the volume of the negative electrode product changes, and at this time, the top plate 4 floats up and down with the volume change of the negative electrode product.

[0026] The fifth embodiment of the utility model is substantially the same as the first embodiment, mainly in that the top plate 4 is smaller than the box body surrounded by the box plate 1 and the support member 3, and the top plate 4 is non-fixedly placed on the box body surrounded by the box plate 1 and the support member 3. During production, the box body is filled with negative electrode products, and the top plate is placed on top. During the production process, the volume of the negative electrode products will change, and at this time, the top plate 4 will not float up and down with the volume change of the negative electrode products.
