Abstract
A strip steel pickling tank support roller comprises a roller core and a roller sleeve, wherein, the roller sleeve is a composite roller sleeve which comprises an inner layer and an outer layer consisting of a low friction coefficient material layer and a high friction coefficient material layer. The support roller solves the problem of the blockage of key parts of a system caused by the breaking off of the hard rubber of the prior support roller; meanwhile, the support roller can rotate more flexibly along with improved abrasion resistance, thereby prolonging the service life of the support roller. Adopting the form of a multi-segment roller sleeve, the utility model skillfully solves the problems of the abrasion resistance and rotation flexibility of the support roller.
Description
Technical field
The utility model relates to the pickling tank carrying roller in the pickling technology, relates in particular to a kind of pickling tank carrying roller with steel.
Background technology
Therefore the pickling tank of acid cleaning process section has arranged some carrying rollers in order to prevent to damage the acid resisting brick in band steel and the wearing and tearing acid tank in acid tank, the band steel that can avoid like this moving directly contacts with the acid tank bottom land.
As shown in Figure 1, roller core 30 skins of existing carrying roller are roller core line with rubber 40, all covered by roller shell 50 on the line with rubber roller core 40, the two ends of roller core 30 are provided with axle sleeve 20, the two ends of this carrying roller are embedded in the base 10, roller core 30 all is the identical acid-resisting rubbers of performance with the rotation contact surface of roller shell 50, and the gap of roller core 30 and roller shell 50 and the gap between the roller shell are all less than 0.5mm.
In the silicon-steel pickling process, can produce a large amount of silicon mud (main component SiO2),, make silicon mud be deposited in the carrying roller zone, form certain resistance, make carrying roller rotate comparatively difficulty because existing carrying roller design is unreasonable.
The problem that existing idler structure exists: 1) roller core and roller shell rotation contact surface all is the approaching acid-resisting rubbers of performance, and the frictional force of roller shell rotation is rotated dumb greatly; 2) gap design between roller core and roller shell and the roller shell is less than normal, under 70～85 ℃ of Working environments, and roller core and roller shell expanded by heating; Down, temperature influence causes the state between roller core and roller shell and the roller shell that variation has taken place to original carrying roller in working order, and running fit becomes shrink-fit, causes roller shell to rotate.3) behind the roller shell expanded by heating self breakage takes place very easily; These reasons have caused original carrying roller short work-ing life.
Above-mentioned carrying roller has caused following point in actual use: 1) roller shell of original carrying roller can't rotate and cause the roller shell inordinate wear and break coming off, operation band steel and the friction of immobilized roller core cause the roller core line with rubber to damage, and the steel core that causes carrying roller is exposed to the irregular corrosion of generation in the acid solution, and operation band steel contacts with irregular roller core and causes belt steel surface to scratch; 2) the abrasive dust thing of roller shell inordinate wear and the cast that breaks enter acid solution, cause the pipeline of whole pickling system, the obstruction of spraying beam endoporus, graphite heater, cause the big problem of flow rate fluctuation.
Summary of the invention
The purpose of this utility model is to provide a kind of strip pickling groove carrying roller, thereby the expanded by heating influence and the carrying roller that solve in the pickling rotate inflexible problem.
For reaching above-mentioned purpose, the utility model provides a kind of strip pickling groove carrying roller, its two ends are coated with axle sleeve, the two ends of this carrying roller are embedded in the base, described carrying roller comprises roller core and roller shell, described roller shell is compound roller shell, and this compound roller shell comprises internal layer and the skin of being made up of low-friction coefficient material layer and high coefficient of friction material layer.
Preferably, described internal layer low-friction coefficient material layer is that natural rubber adds graphite; Described outer high coefficient of friction material layer is wear-resisting paracril.
Outside described roller core, also be coated with an etch resistant material layer.This etch resistant material layer is that ladle covers polytetrafluoroethylene floor.
Preferably, the hardness of the outer high coefficient of friction material layer of described roller shell is shore70 °～80 °.
More preferably, described compound roller shell is a multi-stage type, and roller shell leaves gap 10～60mm on roller core.
This strip pickling groove carrying roller has solved the system core position blocking problem that coming off of original carrying roller vulcanite caused, and it is more flexible to make that simultaneously carrying roller rotates, and its wear resistance is improved, thereby has improved the work-ing life of carrying roller.What the utility model adopted is the form of the compound roller shell of multistage, has solved the wear resistance of carrying roller and the flexibility problem of rotation dexterously, and good effect is arranged in real work.
