[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 5 A hot rolling roller assembly convenient for steam heating comprises a roller body mechanism 1, a roller body shell 101, a through-pipe hole 102, a threaded hole 103, a cavity 104, a side shell mechanism 2, a cover plate 201, a through-slot 202, a conversion plate 203, a flow hole 204, a shaft tube 205, a screw 3, a steam pipe 4 and a gear 5. The side shell mechanism 2 is connected to the roller body mechanism 1 on both sides by screws 3. Specifically, considering the connection effect between the roller body mechanism 1 and the side shell mechanism 2, grooves for accommodating the installation of the side shell mechanism 2 are provided on both sides of the roller body shell 101, and a plurality of grooves are provided in an annular manner at equal intervals inside the grooves. A threaded hole 103 is formed, and the internal thread of the threaded hole 103 is connected with a screw 3, which is convenient for the screw 3 to be stably installed. At the same time, the outer wall of the cover plate 201 is connected with an edge connected and installed with the roller shell 101, and the internal thread of the edge is penetrated and connected with multiple groups of screws 3, which ensures the connection stability between the roller body mechanism 1 and the side shell mechanism 2. Further, in order to achieve the driving effect of the hot rolling roller, the shaft tube 205 is arranged at the axis of the cover plate 201, and the outer wall of the shaft tube 205 is fixedly connected with a gear 5 for driving, so that the hot rolling roller assembly can be driven to rotate through the shaft tube 205;

[0032] Furthermore, in order to achieve uniform circulation of steam inside the roller mechanism 1, the roller mechanism 1 includes a roller shell 101 inside, and a cavity 104 is provided at the central axis of the roller shell 101. The provision of the cavity 104 reduces the overall weight of the roller shell 101 and reduces the production cost. At the same time, ten groups of through-tube holes 102 are equidistantly provided in an annular manner on the outer wall of the cavity 104, and steam pipes 4 are provided inside the ten groups of through-tube holes 102 to ensure the circulation effect of steam inside the roller shell 101. The two sides of the steam pipe 4 are bent in a "J"-shaped structure to facilitate external connection of a circulation device at both ends of the steam pipe 4. In order to achieve steam uniformity, ten groups of steam pipes 4 are equidistantly provided in an annular manner about the through-tube holes 102 inside the roller shell 101.

[0033] Since the two sides of the steam pipe 4 are arranged in a "J"-shaped structure, in order to uniformly collect multiple groups of bent steam pipes 4 and reasonably utilize the space at both ends of the roller shell 101, a cover plate 201 is included inside the side shell mechanism 2, and a through groove 202 is opened on the surface of the cover plate 201 corresponding to the through pipe hole 102. Specifically, the through groove 202 is radially arranged in a "M"-shaped structure, and the number of radial through grooves 202 corresponds to the number of through pipe holes 102, so that the steam pipes 4 arranged in the "J"-shaped structure can be unified inside the through groove 202, and the shaft tube 205 is connected to the other side of the cover plate 201, and the shaft tube 205 is connected to the cover plate 2 01, through the circulation hole 204 penetrated through the conversion plate 203, the two ends of the steam pipe 4 can be set through the circulation hole 204 through the through groove 202. Through such a setting, when the outside of the shaft tube 205 is connected to the circulation device for air intake, it can enter the multiple groups of steam pipes 4 through the conversion plate 203 respectively, so that the multiple groups of steam pipes 4 can heat the roller shell 101 evenly, and under the action of the "J" type structure of the steam pipe 4, the other end of the steam pipe 4 can circulate steam, thereby realizing stable heating of the roller shell 101, and the structure is stable and the service life is long.
