Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heat treatment of carbon materials, in particular to a stainless steel crucible used for roasting carbon materials. Background Art
[0002] High-performance carbon materials have the characteristics of low specific gravity, high mechanical strength, good electrical and thermal conductivity, and high-temperature corrosion resistance at high temperatures. They are widely used in mechanical engineering, new energy, aerospace, and atomic energy industries. With the improvement of the performance requirements of carbon materials, the preparation process of carbon materials has become increasingly complex. The most critical preparation process is the roasting process of carbon materials, which is usually carried out in a crucible, and the carbon materials are placed in an oxygen-free or inert gas atmosphere for heat treatment at 800-1200℃.
[0003] Since the heat treatment process of carbon materials involves complex coking reactions, during the crucible roasting process, the carbon materials will emit liquid substances produced by asphalt. When the roasting process is over, these liquids remain at the bottom of the crucible, stick to the surface of the carbon products at the bottom of the crucible and combine with the carbon products, affecting the performance of the carbon products at the bottom, seriously lowering the requirements for high-performance carbon materials and reducing the qualified rate of products. Therefore, the existing crucibles used for roasting carbon materials cannot meet the performance requirements for high-performance carbon materials. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art and provide a stainless steel crucible for calcining carbon materials which has a simple structure and can improve the performance of the carbon materials.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A stainless steel crucible for roasting carbon materials comprises a crucible body, the crucible body is provided with a cavity for accommodating the carbon material, the bottom of the crucible body is provided with a protrusion protruding into the cavity, a first groove is formed between the surface of the protrusion and the wall forming the cavity, and the first groove is used to accommodate liquid substances generated during the roasting process of the carbon material.
[0007] As a further improvement of the above technical solution:
[0008] A second groove is provided at the bottom of the crucible body, and the groove depth direction of the second groove is the same as the height direction of the crucible body.
[0009] The bottom plate of the crucible body is bent toward the cavity to form the protrusion in the cavity, and the second groove is formed at the bottom of the crucible body.
[0010] The protrusions include a longitudinal protrusion and a transverse protrusion that intersect vertically, the longitudinal protrusion extends along the length direction of the crucible body, and the transverse protrusion extends along the width direction of the crucible body, and the second grooves correspondingly include a longitudinal groove and a transverse groove that intersect vertically.
[0011] The upper surface of the protrusion is a smooth curved surface.
[0012] It also includes a crucible cover, the top of the crucible body is provided with a third groove, the groove depth direction of the third groove is the same as the height direction of the crucible body, and the bottom of the crucible cover is inserted into the third groove to cooperate with the crucible body.
[0013] The third groove is an annular groove surrounding the crucible body, and the bottom of the crucible cover is correspondingly inserted into the annular groove.
[0014] The crucible cover is provided with a handle.
[0015] Compared with the prior art, the advantages of the utility model are: when the stainless steel crucible of the utility model is used for roasting carbon materials, the carbon material is placed in the cavity. Due to the protrusion, the carbon material will not directly contact the bottom surface of the cavity. During the roasting process, the liquid substance produced by the asphalt discharged by the carbon material will flow into the first groove from top to bottom. When the roasting process is over, these liquid substances will not stick to the surface of the bottom carbon product, but will be temporarily stored in the first groove, so that they will not be combined with the bottom carbon product and will not affect the performance of the bottom carbon product. The performance requirements of high-performance carbon materials are met, the performance of the carbon materials after roasting is improved, and the qualified rate of the products can also be improved, and subsequent cleaning is convenient.

The stainless steel crucible of the present embodiment is used for roasting carbon materials. When in use, the carbon material is placed in the cavity 11. Due to the protrusion 12, the carbon material will not directly contact the bottom surface of the cavity 11. During the roasting process, the liquid substance produced by the asphalt discharged by the carbon material will flow into the first groove 13 from top to bottom. When the roasting process is completed, these liquid substances will not stick to the surface of the bottom carbon product, but will be temporarily stored in the first groove 13, so that they will not be combined with the bottom carbon product and will not affect the performance of the bottom carbon product. The performance requirements of high-performance carbon materials are met, the performance of the carbon materials after roasting is improved, and the qualified rate of the products can also be improved, and subsequent cleaning is convenient.
[0025] In this embodiment, a second groove 14 is provided at the bottom of the crucible body 1, and the groove depth direction of the second groove 14 is the same as the height direction of the crucible body 1. The second groove 14 is provided at the bottom of the crucible body 1.

[0026] In this embodiment, the bottom plate of the crucible body 1 is bent toward the cavity 11, a protrusion 12 is formed in the cavity 11, and a second groove 14 is formed at the bottom of the crucible body 1. The liquid substance produced by the asphalt discharged from the carbon material during the roasting process can flow into the first groove 13, and the second groove 14 can also be used for transportation, and the structure is simple, the production is convenient, and the price is low. In this embodiment, the crucible body 1 is a rectangular parallelepiped structure, and the side plates of the crucible body 1 are whole plates, with a complete structure and high strength. In other embodiments, the crucible body 1 can also be set to other shapes.
[0027] In this embodiment, the protrusion 12 includes a longitudinal protrusion 121 and a transverse protrusion 122 that intersect vertically.

The second groove 14 correspondingly includes a longitudinal groove 141 and a transverse groove 142 that intersect vertically. This can ensure the structural strength of the crucible body 1, increase the load-bearing capacity of the crucible, and make it durable. In this embodiment, the crucible body 1 has a cuboid structure. There is one longitudinal protrusion 121, and its length is equal to that of the crucible body 1. The longitudinal protrusion 121 is provided at the central position of the crucible body 1. There are two transverse protrusions 122, and their widths are equal to that of the crucible body 1. The two transverse protrusions 122 are arranged at intervals and symmetrically arranged along the central plane of the crucible body 1. The second groove 14 is correspondingly arranged with the protrusion 12. In this embodiment, the longitudinal protrusion 121 and the transverse protrusion 122 form a "艹" - shaped structure, and in other embodiments, they can also form a "井" - shaped structure.
[0028] In this embodiment, the upper surface of the protrusion 12 is a smooth arc surface. This facilitates subsequent cleaning of the liquid substance.
