[0027] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0028] like Figure 1-8The special steel drum with an insulating layer shown in the figure comprises a steel cylinder 5 made of an alloy material. The steel cylinder 5 is cylindrical and comprises a coaxial inner cylinder 501 and an outer cylinder 502. Due to the different diameters, the inner cylinder 501 is naturally located in the outer cylinder 502. The upper ends of the inner cylinder 501 and the outer cylinder 502 are commonly connected with a top transition ring 503, and the lower ends of the inner cylinder 501 and the outer cylinder 502 are commonly connected with a bottom transition ring 504. The top transition ring 503 and the bottom transition ring 504 smoothly transition from the inner cylinder 501 to the outer cylinder 502. The inner wall of the inner cylinder 501 expands outward to form a ring ridge 505, which can increase the inner cylinder 5 01 The circumferential deformation resistance is improved, thereby improving the compressive strength of the inner cylinder 501. There are several ring ribs 505. Although the sizes of these ring ribs 505 may be different, they are all coaxial with the inner cylinder 501. An insulating cavity 506 is formed between the inner cylinder 501 and the outer cylinder 502, which can slow down the heat exchange inside and outside the entire steel barrel, thereby ensuring the relative stability of the temperature of the stored objects in the steel barrel during transportation. The insulating cavity 506 is sealed by the top transition ring 503 and the bottom transition ring 504, so the inside of the insulating cavity 506 can be filled with gases such as carbon dioxide, or it can be evacuated to have better thermal insulation performance.

[0029] The steel cylinder 5 is provided with a sleeve 1 made of a rubber material. The sleeve 1 made of rubber has the functions of insulation, heat insulation, wear resistance and shock resistance. The bottom of the sleeve 1 is closed and only the upper end is open. The sleeve 1 includes a coaxial inner coating 101 and an outer coating 102. Due to the different diameters, the inner coating 101 is located inside the outer coating 102. The upper ends of the inner coating 101 and the outer coating 102 are connected to an upper coating 103. The lower ends of the inner coating 101 and the outer coating 102 are connected to a lower coating 104. The upper coating 103 and the lower coating 104 are connected to the inner coating 101 and the outer coating 102 by hot melting. Connected together, a configuration cavity 106 is formed between the inner covering layer 101 and the outer covering layer 102 for accommodating the steel cylinder 5. The outer side surface of the inner covering layer 101 has a plurality of coaxial annular edges 105. The number and shape of the annular edges 105 correspond to the annular ridges 505. Therefore, the annular edges 105 can fit on the inner wall of the annular ridges 505, which can effectively prevent the inner covering layer 101 from moving relative to the inner cylinder 501. The inner wall of the inner covering layer 101 has a partition membrane 107. It is precisely because of the partition membrane 107 that the lower open end of the entire sleeve 1 is closed. The partition membrane 107 is close to the lower covering layer 104, that is, close to the lower end of the entire sleeve 1.

[0030] The lower end of the cylinder sleeve 1 is sleeved with a base 2 made of plastic, which has good wear resistance and light weight. The specific structure of the base 2 includes a chassis 201, and the chassis 201 has a buffer cavity 202 inside, which is also a load-reducing cavity for the entire base 2, and can absorb the impact force when the steel drum is placed by extrusion deformation. The upper surface of the chassis 201 has an extension ring 203, and the extension ring 203 obviously protrudes from the upper surface of the chassis 201. The upper surface of the chassis 201 is provided with a fitting groove 204 located in the extension ring 203, and the inner wall of the fitting groove 204 is just in contact with the bottom surface of the lower covering layer 104. After fitting, the outer surface of the outer covering layer 102 will be in close contact with the inner wall of the extension ring 203. Due to the friction force, the entire base 2 can be fixed more firmly to the lower end of the steel cylinder 5.

[0031] An inner plate 4 is provided at the inner bottom of the sleeve 1. The inner plate 4 is also made of alloy material. A bottom sleeve 3 made of rubber is provided outside the inner plate 4. The bottom sleeve 3 has a receiving cavity 301 to accommodate the inner plate 4. A friction groove 401 is provided on the end surface of the inner plate 4 to inhibit the bottom sleeve 3 from moving relative to the inner plate 4.

[0032] Manufacturing method: The first step is to manufacture the steel cylinder 5. First, the inner cylinder 501 is formed by stamping, and then the top transition ring 503 and the bottom transition ring 504 are integrally stamped with the outer cylinder 502. Then, the upper and lower ends of the inner cylinder 501 are sealed and welded with the top transition ring 503 and the bottom transition ring 504 by hot melting. The second step is to manufacture the cylinder sleeve 1. First, the inner coating 101 with the ring edge 105 and the partition film 107 is tightly attached to the inner wall of the inner cylinder 501, and then the outer coating 102 is sleeved on the outer side of the outer cylinder 502. Finally, the upper coating 103 is sealed by hot melting. The lower covering layer 104 is sealed and connected with the upper and lower ends of the inner covering layer 101 and the outer covering layer 102 respectively; the third step is to cover the bottom sleeve 3 on the inner panel 4 by injection molding; the fourth step is to injection mold the entire base 2; finally, the inner panel 4 with the bottom sleeve 3 is placed in the steel cylinder 5 with the cylinder sleeve 1, and contacts with the upper surface of the partition membrane 107. Due to the support of the partition membrane 107 and the friction between the bottom sleeve 3 and the inner panel 4, the inner panel 4 embedded in the steel cylinder 5 will be very stable. Finally, the base 2 is put on the bottom of the steel cylinder 5 to complete the assembly.
