Abstract
The utility model relates to the field of cold rolling, in particular to a sink roll for a cleaning section. In a sink roll with the spiral grooves, the spiral grooves are arranged on the outer surface of a rubber coating layer on the surface of the sink roll. The length of each spiral groove is shortened by the three spiral grooves which are uniformly distributed on the surface of the sink roll, so that paths in the grooves for cleaning liquid to flow out are shortened, the cleaning liquid can be discharged from the grooves more quickly, and the water drainage efficiency is improved; and the circular arc-shaped groove bottoms can improve the smoothness of the cleaning liquid, and compared with right-angle groove bottoms, impurities in the cleaning liquid can be more conveniently discharged, and scales are prevented from being formed at the groove bottoms. In a word, the sink roll with the spiral grooves effectively eliminates a liquid membrane between strip steel and the sink roll, so that the horizontal sliding phenomenon of the strip steel when running at a high speed is reduced, the phenomenon that the strip steel offsets is thoroughly avoided, and the stable operation of a unit is ensured.
Description
Technical field
The utility model relates to cold rolling field, relates in particular to a kind of cleaning section sinking roller.
Background technology
Cleaning section is as an important preprocessing section of cold rolling tinuous production, and the quality of cold-strip steel is had very big influence.And the sinking roller plays crucial effect as the key equipment of cleaning section to quality and the stable logical plate of being with steel.The domestic and international at present cleaning section sink roll face that generally uses all is a plain-barreled roll, owing to have certain cornerite between band steel and the sinking roller, when being with steel and sinking roller to rotate at a high speed, the meeting under the state of extruding of the cleaning fluid between band steel and the roll surface forms liquid film.The existence of this liquid film can not fit tightly the band steel with the sink roll face, and produces horizontal slippage at roll surface, causes being with steel at cleaning section generation sideslip, thereby the steady production of unit is impacted.
In order to reduce the liquid film between band steel and the sink roll face, reach the purpose of improving strip running deviation, a kind of sinking roller at the roll surface fluting is disclosed in the prior art, as shown in Figure 1, the rubber adhesive outer surface of this sink roll face has equidistant circumferential slot 1, utilize the roll surface elimination liquid film of circumferentially slotting, strengthen the operation of band steel to neutral and stable.
But there are two bigger defectives in the sinking roller of this circumferential fluting.On the one hand, along the very difficult elimination that realizes liquid film of the circumferential groove of sinking roller, because under the high-speed cruising state, the fluting of roll surface can amass Qing Dynasty's washing lotion.And owing to be with the parcel of steel to roll surface, the cleaning fluid in the cutting can flow along the direction of rotation of sinking roller.On the other hand, because the existence of this circumferential cutting for the specification of certain width, exists the risk in the strip edge portion card entry slot.Also may cause being with steel under the serious situation, cause unit can't stablize logical plate at the cleaning section broken belt.And because the existence of cutting can aggravate the incised wound of strip edge portion to roll surface, thereby shortened service life of sinking roller.
The utility model is to open spiral groove at the sink roll face, not only can effectively eliminate the liquid film between band steel and roller, prevents to be with steel at cleaning section generation sideslip.But also eliminated the risk of roll surface fluting cassette tape steel, to there not being negative effect in service life of sinking roller yet.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of helicla flute sinking roller, this sink roll face has helicla flute, helicla flute can make outside the cleaning fluid distributing roller of sink roll face, thereby eliminate the liquid film between band steel and the sinking roller, band steel and sink roll face are fitted tightly, prevent to be with steel that sideslip takes place in high-speed motion.
The utility model is achieved in that a kind of helicla flute sinking roller, and the rubber adhesive outer surface of this sink roll face has helicla flute.
Described helicla flute has 3, is evenly distributed on the rubber adhesive outer surface of sink roll face.
Described helicla flute bottom is a circular arc.
Helicla flute on the utility model helicla flute sink roll face can cleaning fluid distributing roller with the sink roll face outside, thereby eliminate the liquid film between band steel and the sinking roller, band steel and sink roll face are fitted tightly, prevent to be with steel that sideslip takes place in high-speed motion, and steel limit portion can card entry slot in, avoided the generation of broken belt accident; Article 3, uniform helicla flute has shortened every spiral fluted length, has shortened the path that the groove cleaning liquid inside flows out, and cleaning fluid can be discharged in groove faster like this, thereby has improved the efficient of draining; The bottom land of circular arc can increase the fluency of cleaning fluid, compares with the bottom land of square, and the discharge that the impurity in the cleaning fluid can be convenient prevents to form fouling at bottom land.Generally speaking the utility model has effectively been eliminated the liquid film between band steel and the sinking roller, has reduced the horizontal sliding phenomenon of band steel when running up, the generation of thoroughly stopping strip running deviation, thereby the stable operation of assurance unit.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As shown in Figure 2, a kind of helicla flute sinking roller, the rubber adhesive outer surface of this sink roll face has helicla flute 2.
In order to shorten the length of helicla flute 2, cleaning fluid can be flowed out faster, described in the present embodiment helicla flute 2 has 3, is evenly distributed on the rubber adhesive outer surface of sink roll face.By the length that shortens every helicla flute 2 cleaning fluid can be discharged faster in groove on the one hand, thereby improved the efficient of draining, on the other hand, evenly open 3 helicla flutes 2 and can shorten spacing between every groove, increase the fluting quantity on the unit roll surface, so just increase displacement, thereby also improved drainage efficiency.
Present embodiment can further describe into, described helicla flute 2 bottoms are circular arc, the bottom land of circular arc can avoid the dirt in the cleaning fluid to pile up at bottom land, prevents to form fouling at bottom land, influences the fluency of cleaning fluid.
Claims (3)
1. helicla flute sinking roller, it is characterized in that: the rubber adhesive outer surface of this sink roll face has helicla flute (2).
