Description

Technical Field

[0001] The utility model belongs to the technical field of the graphite support system of a heating furnace, and particularly relates to a graphite support roll system of a heating furnace for preventing a graphite sleeve and a mandrel from being worn and broken. Background Art

[0002] In a heating furnace, two spare steel wires for a pulling belt are arranged on the graphite roll. When the graphite roll rotates to drive the annealing steel belt to translate, the rotating roll will rub against the contacting steel wire. When the graphite sleeve is worn to a certain size, the steel wire will cause the graphite sleeve to be worn through or broken. During the continuous rotation process, the steel wire will contact the surface of the mandrel. During continuous use, the steel wire will wear the mandrel, thereby causing the mandrel to be worn or broken or having deep grooves ground out. When the mandrel rotates, it is easy to cause the steel wire to be stuck or the steel wire to be wound, affecting the use safety and the smooth and reliable use, and the practicability is limited. Summary of the Invention

[0003] The purpose of the utility model is to provide a graphite support roll system of a heating furnace for preventing a graphite sleeve and a mandrel from being worn and broken, which has a reasonable structure setting and is beneficial to improving the use smoothness.

[0004] The technical solution for realizing the purpose of the utility model is a graphite support roll system of a heating furnace for preventing a graphite sleeve and a mandrel from being worn and broken, including a steel mandrel, and a graphite roll sleeve is arranged on the outer ring of the steel mandrel;

[0005] The middle part of the top surface of the graphite roll sleeve contacts with an annealing steel belt, and both ends of the top surface of the graphite roll sleeve abut against a preset steel wire;

[0006] An anti-wear and breakage steel pipe parallel to the steel mandrel is arranged on the outer side of the graphite roll sleeve;

[0007] The top surface of the anti-wear and breakage steel pipe is between the top surface of the steel mandrel and the top surface of the graphite roll sleeve in height.

[0008] Further preferably: the diameter of the anti-wear and breakage steel pipe is 3-5 cm;

[0009] After the graphite roll sleeve is worn through or broken by the preset steel wire, it is attached and suspended on the top surface of the anti-wear and breakage steel pipe.

[0010] Further preferably: the diameter of the steel mandrel is 55 cm;

[0011] The outer diameter of the graphite roll sleeve is 90 cm.

[0012] Further preferably: the number of the anti-wear and breakage steel pipes is one.

[0014] The utility model has positive effects: the structure of the utility model is reasonably arranged, and an anti-wear and anti-breaking steel pipe is additionally provided. Thus, when the prefabricated steel wire wears through or breaks the graphite roller sleeve, it will be supported overhead on the surface of the anti-wear and anti-breaking steel pipe and will no longer continue to wear the rotating steel core shaft, thereby avoiding the jamming of the steel wire or the accident of steel wire entanglement, being beneficial to improving the use stability and reliability, and having strong applicability and good practicability.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model. Embodiment

[0020] See Figures 1 to 2 As shown, a heating furnace graphite support roller system for preventing the graphite sleeve and the core shaft from being worn and broken includes a steel core shaft 1, and a graphite roller sleeve 2 is arranged on the outer circle of the steel core shaft; in this embodiment, both the steel core shaft and the graphite roller sleeve are conventional structures of the prior art, and are only simply applied. And during the actual application process, an annealing steel strip 3 contacts the middle part of the top surface of the graphite roller sleeve, and prefabricated steel wires 4 abut against both ends of the top surface of the graphite roller sleeve; an anti-wear and anti-breaking steel pipe 5 parallel to the steel core shaft is arranged on the outer side of the graphite roller sleeve; the top surface of the anti-wear and anti-breaking steel pipe is between the top surface of the steel core shaft and the top surface of the graphite roller sleeve in height. When the prefabricated steel wire wears the graphite roller sleeve for a long time, it will gradually wear or break the graphite roller sleeve. At this time, the prefabricated steel wire will be supported overhead on the surface of the anti-wear and anti-breaking steel pipe, thereby preventing the prefabricated steel wire from continuing to wear the rotating steel core shaft and being beneficial to improving the use stability and reliability of the steel core shaft.

[0021] In the actual application process, the diameter of the anti-abrasion and anti-breakage steel pipe is 3 - 5 cm; after the pre-set steel wire wears through or breaks the graphite roller sleeve, it adheres and is suspended above the top surface of the anti-abrasion and anti-breakage steel pipe. The diameter of the steel core shaft is 55 cm, and it can also be other sizes in the actual application process; the outer diameter of the graphite roller sleeve is 90 cm, and it can also be other sizes in the actual application process. The number of the anti-abrasion and anti-breakage steel pipes is one. The outer surface of the anti-abrasion and anti-breakage steel pipe is close to the outer surface of the side part of the graphite roller sleeve.

[0022] The utility model has positive effects: The structure of the utility model is reasonably arranged. It is provided with an anti-abrasion and anti-breakage steel pipe. Thus, when the prefabricated steel wire wears through or breaks the graphite roller sleeve, it will be suspended and abutted against the surface of the anti-abrasion and anti-breakage steel pipe, and will not continue to wear the rotating steel core shaft. Therefore, it can avoid the jamming of the steel wire or the accident of the steel wire winding, which is beneficial to improving the use stability and reliability, and has strong applicability and good practicability.
