Abstract
The invention relates to an on-line baffling and removing oil method of a cold-rolled aluminum plate and strip. The method is characterized in that the invention comprises two aspects of equipment and technique; 1) equipment: an arc oil baffle plate is arranged above an upper supported roller and an oil deflector which is easy to be assembled and dismantled is arranged at the bottom of an air roller cleaner; an outlet guide plate is perforated and a tilted guide roller is arranged between a pair of scissors and an outlet tilted guide roller; 2) technique: (1) the rolling line is elevated and the adjusting space of a rolling mill can be elevated by 0 to 20 millimeters; (2) the angle and distance of the air blowtorch for sweeping the plate can be adjusted. By adopting the invention, oil falling from the memorial arch does not spatter on support rollers and flows into the air roller cleaner along an upper oil baffle plate; in addition, oil spattered by the upper support roller does not spatter on the memorial arch, which reduces the contact between an aluminum plate and the rolling oil on the outlet guide plate; therefore, the rolling oil on the plate can be cleaned by sweeping and oil spots can not be produced on the aluminum plate.
Description
Technical field
The present invention relates to the aluminium processing technique field, retaining oil, deoiling method that specifically a kind of cold rolled aluminum belt is online.
Background technology
The oil removing of aluminium sheet band is a very complicated technology problem, also can be described as the difficult problem that an aluminium processing industry is faced jointly.Aluminium sheet belt surface band oil not only influences the quality of product, also influences the production cost of products and the market image.The composition of aluminium sheet belt surface oil: mainly be ROLLING OIL and additive, aluminium powder and alumina powder, sneak into machinery oil, hydraulic oil in the ROLLING OIL.The harm of aluminium sheet belt surface oil: aluminium powder and alumina powder can form the sump oil spot at the aluminium sheet belt surface, only can't remove by annealing operation; Machinery oil, the hydraulic oil of sneaking in the ROLLING OIL can make the aluminium sheet belt surface form the butter spot after annealing.
Summary of the invention
The purpose of this invention is to provide a kind of cold rolled aluminum belt online retaining oil, deoiling method, eliminated aluminium sheet belt surface oil and oil mark.
The present invention is directed to the different reasons that upper and lower plates face greasy dirt forms, improve respectively from equipment and two aspects of technology, at first is to have installed the oily device of retaining additional, secondly is that some position of equipment is transformed, and is to purge and oil suction at last.Concrete scheme is:
1, equipment aspect: above last roller, adorn an arc oil baffle, in air roller-cleaning device bottom oil guide plate easy to assemble is installed, punching on delivery guide (big aperture does not wait) increases a rectification roll between scissors and outlet rectification roll, install vacuum pressure-vaccum oil device between two rectification rolls additional.
2, process aspect: 1. improve roll line, milling train can improve 0～20 millimeter adjusting space, reduces the chance that aluminium sheet contacts with ROLLING OIL on the delivery guide; The angle and distance of the air blow gun that purges the plate face can suitably be adjusted according to plate is wide.
The improvement of equipment of the present invention and technology brings following good effect:
1. above last roller, adorn an arc oil baffle, make on the memorial archway fallen oil not fall on the backing roll, but flow on the air roller-cleaning device along last oil baffle, the oil that has been got rid of by top backing up roll no longer splashes on the memorial archway in addition, but flows on the air roller-cleaning device along last oil baffle; 2. in air roller-cleaning device bottom oil guide plate easy to assemble is installed, is made the oil that flows down from the air roller-cleaning device directly be directed to oil trap; 3. on delivery guide, punch, long-pending oil mass is reduced as far as possible, 4. improve roll line, reduce contacting of ROLLING OIL on aluminium sheet and the delivery guide; 5. the angle and distance that purges the air blow gun of plate face can suitably be adjusted according to plate is wide, makes the ROLLING OIL on the plate purge totallyer: 6. add a rectification roll again between scissors and outlet rectification roll, just can install the vacuum Oil sucking device additional between two rectification rolls; Use the oil film wedge between first rectification roll of air purge and the aluminium sheet in addition, make and be with oil mass to minimize on the aluminium sheet, prevent that the aluminium sheet belt surface from forming the butter spot after annealing.
Description of drawings
Fig. 1 is the online structural scheme of mechanism of cold rolled aluminum belt of the present invention.
Among the figure, 1-oil baffle, 2-air roller-cleaning device, 3-oil guide plate, 4-outlet side rectification roll, 1,5-outlet side rectification roll, 2,6-aluminium strip, 7-guide plate.
The specific embodiment
1, equipment aspect: as shown in Figure 1, above last roller, adorn an arc oil baffle 1; Oil guide plate 3 easy to assemble is installed in the bottom of air roller-cleaning device 2; On delivery guide 7, beat the hole that some shapes differ in size, between scissors and outlet rectification roll 5, increase a rectification roll 4, and leave 300-400 mm distance between two rectification rolls,, the part high-temperature oil mist is siphoned away so that vacuum pressure-vaccum oil device (conventional device) is installed.
2, process aspect: 1. improve roll line, milling train can improve 0～20 millimeter adjusting space, reduces the chance that aluminium sheet contacts with ROLLING OIL on the delivery guide; 2. purge the angle and distance of the air blow gun of plate face according to the wide suitable adjustment vacuum pressure-vaccum oil device of plate.
Claims (1)
1, online retaining oil, the deoiling method of a kind of cold rolled aluminum belt is characterized in that comprising equipment and technology two aspects:
1) equipment aspect: above last roller, adorn an arc oil baffle, in air roller-cleaning device bottom oil guide plate easy to assemble is installed, on delivery guide, punch, between scissors and outlet rectification roll, increase a rectification roll, install vacuum pressure-vaccum oil device between two rectification rolls additional;
2) process aspect: 1. improve roll line, milling train can improve 0～20 millimeter adjusting space; 2. make the angle and distance of the air blow gun that purges the plate face adjustable.
