Abstract
The invention relates to a vacuum drawing oil removing roller. The vacuum drawing oil removing roller comprises a hollow core shaft which is provided with a vacuum drawing sleeve through a bearing; a spiral groove is formed in the surface of the vacuum drawing sleeve, an oil sucking hole is formed in the groove bottom of the spiral groove, and an oil leakage hole is formed in the hollow core shaft; and vacuum drawing devices are arranged at the two ends of the hollow core shaft. The vacuum drawing oil removing roller is reasonable in structural design, flexible and reliable in running, and capable of effectively removing residual oil on the surface of a nonferrous metal strip on line; in addition, scrapping on the surface of the strip is reduced, and removing of residual oil on the surface of the strip rolled by a ferrous metal plate mill at a high speed is feasible and effective; and compared with an imported 3M oil removing roller, the manufacturing cost is low, and maintenance is avoided.
Description
technical field:
The present invention relates on non-ferrous metal strip cold-rolling mill except oiling roller, particularly a kind of degreasing unit of high accuracy non-ferrous metal band surface when high-speed rolling.
background technology:
In order to improve rolling mill speed and stability in non-ferrous metal cold mill complex, reduce roll torque, reduce roller surface temperature, the operation of rolling adopts complete oily technological lubrication, and this is the needs of rolling mill practice, but the ROLLING OIL of strip surface must be removed in finished product volume, otherwise, when curling, easily produce skidding, after annealing, a large amount of ROLLING OIL will pollute surface quality of strips, affect product surface quality.On modern high accuracy nonferrous metal rolling mill, the ROLLING OIL residual in strip surface, decides the production efficiency of complete machine and the quality of finished product band.Rolling high precision non-ferrous metal band often occurs that Oil residue on surface is large, causes mill speed low, and production capacity plays not out, and production cost is high because ROLLING OIL is not except clean.How to improve non-ferrous metal strip-mill strip deoiling effect, ensureing milling train stable operation under designed high speed, is a non-ferrous metal band surface degreasing industry technology difficult problem.
The patent No. is the utility model patent of 201120106963.1, disclose a kind of suction for steel industry vacuum web and remove oiling roller, through hole should be set except oiling roller inner hollow, except oiling roller surface, non-woven fabrics is set with except outside oiling roller, except oiling roller connects vacuum plant, the stressed easy distortion of this oil removing mode non-woven fabrics operation of rolling, roll hardness is inadequate, easily dirty, need periodic cleaning and frequent replacing.
The patent No. is the utility model patent of 201320141543.6, disclose a kind of stainless steel band cold-rolled band surface except oiling roller, this patent is mainly through removing oiling roller Surface coating 30 ~ 50mm high strength adhesive-bonded fabric fibrage, by high strength adhesive-bonded fabric fibrage and band friction, by extruding removing strip surface greasy dirt, be applied to the oil removing of stainless-steel cold-rolling strip surface.
For the non-ferrous metal band and strip rolling mill adopting full oil lubrication, before the machine of reversable mill, after machine, must degreasing unit be set, general by squeezing oiling roller in pairs, 3M roller or form vacuum noncontact except wet goods by vacuum tightness die cavity, or independent air knife purges, but existing existing degreasing technique all can not meet the requirement of milling train high speed (speed the is greater than 350m/min) steady production using high viscosity ROLLING OIL, and import 3M except oiling roller expensive, frequent maintenance, strip surface deoiling effect has become this type of milling train to come into force the bottleneck of efficiency and surface quality of strips.
summary of the invention:
The present invention can not the common technology difficult problem of Ex-all in order to solve ROLLING OIL in the current non-ferrous metal operation of rolling, reduce copper strip Oil residue on surface, improve rolling rate and product percent of pass, reduce ROLLING OIL consumption and the pollution to environment simultaneously, economic benefit is brought to enterprise, there is provided a kind of vacuum draw except oiling roller, in the high accuracy non-ferrous metal band operation of rolling, remove the Residual oil of outlet strip surface.
The technical solution adopted for the present invention to solve the technical problems:
