Abstract
The utility model relates to the technical field of rollers, in particular to a novel supporting roller for band steel, which comprises a supporting roller group which is arranged up and down, wherein the supporting roller group comprises an upper roller and a lower roller, the upper roller is horizontally arranged at the upper end of a working roller group, and the lower roller is horizontally arranged at the lower end of the working roller group; the upper roller and the lower roller respectively comprise a roller body, a bearing gear and a transmission end; bearing shelves are respectively fixed at two ends of the roller body, and a transmission end is fixed at one side of each bearing shelf. The novel strip steel supporting roller is simple in structure, and can improve the high wear resistance, high yield strength and high anti-stripping capability of the whole roller, so that the service life of the whole roller is prolonged, and the novel strip steel supporting roller is convenient to popularize and use widely.
Description
Technical Field
The utility model belongs to the technical field of the technique of roll and specifically relates to a novel backing roll for belted steel.
Background
The back-up roll that hot rolling strip steel finishing mill group used, its main effect is for providing the support for the working roll, can bear huge pressure for the working roll when rolling operation rolled piece passes through, keeps the working roll normal operating as required. Therefore, the support roller must have a good rigidity, and must have a high fatigue strength, toughness and fracture resistance because the support roller is always in rolling contact with the work roller for a long period of time. Therefore, the perfect combination of high wear resistance, high yield strength and high flaking resistance of the roll body and high strength, high toughness and fracture resistance of the roll neck is essential for the backup roll.
At present, the material of the supporting roller used by domestic strip steel comprises forged steel and alloy steel. Because the supporting roller is always in rolling contact with the working roller, the roller surface is always subjected to contact fatigue cracks, and the roller body is finally peeled off due to the expansion of microcracks. Meanwhile, alternating bending stress is borne on a contact line, the middle part of the supporting roll is seriously abraded, a groove is formed, and the contact stress at two ends of the roll body is greatly increased, so that the falling shoulder is peeled off.
Disclosure of Invention
The to-be-solved technical problem of the utility model is: in order to solve the problems existing in the background technology, the novel strip steel supporting roller is provided, has a simple structure, can improve the high wear resistance, the high yield strength and the high anti-stripping capability of the whole roller, thereby prolonging the service life of the whole roller and being convenient for wide popularization and use.
The utility model provides a technical scheme that its technical problem adopted is: a novel supporting roller for strip steel comprises a supporting roller set which is arranged up and down, wherein the supporting roller set comprises an upper roller and a lower roller, the upper roller is horizontally arranged at the upper end of a working roller set, and the lower roller is horizontally arranged at the lower end of the working roller set; the upper roller and the lower roller respectively comprise a roller body, a bearing gear and a transmission end; bearing shelves are respectively fixed at two ends of the roller body, and a transmission end is fixed at one side of each bearing shelf.
Further, in the above technical solution, the work roll group is a work roll arranged in parallel up and down.
Further, in the above technical solution, the transmission end is a flat square transmission end.
Further, in the technical scheme, the upper roll is in contact with the working roll group.
Further, in the above technical solution, the lower roll is in contact with the work roll group.
The utility model has the advantages that: the utility model provides a novel backing roll for belted steel, simple structure can improve high wearability, high yield strength and the high antistripping ability of whole roll to improve the life of whole roll, be convenient for extensively promote and use.

Detailed Description
As shown in figure 1, the novel supporting roller for the strip steel comprises a supporting roller set which is arranged up and down, wherein the supporting roller set comprises an upper roller 1 and a lower roller 2, the upper roller 1 is horizontally arranged at the upper end of a working roller set 3, and the lower roller 2 is horizontally arranged at the lower end of the working roller set 3; the upper roller 1 and the lower roller 2 both comprise a roller body 4, a bearing gear 5 and a transmission end 6; two ends of the roller body 4 are respectively fixed with a bearing guard 5, and one side of the bearing guard 5 is fixed with a transmission end 6.
Wherein, the working roller group 3 is a working roller which is arranged in parallel up and down. The driving end 6 is a flat square driving end. The upper roll 1 is in contact with the set of work rolls 3. The lower roll 2 is in contact with the set of work rolls 3.
The utility model provides a novel backing roll for belted steel has following advantage for traditional roll: the structure is simple, the high wear resistance, the high yield strength and the high anti-stripping capability of the whole roller can be improved, and the service life of the whole roller is prolonged.
The above-mentioned, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
