Technical field
The present invention relates to a kind of fast automatic cleaning devices of milling train greasy dirt, belong to metallurgy industry Rolling production equipment and technology
Field.
Background technique
Steel rolling process is divided into hot rolling and cold rolling, and in cold-rolling process, the volatilization of rolling emulsion will cause milling train machine
Remaining oil droplet on frame, oil droplet, which drops onto milled sheet and takes, can generate the mass defects such as oil mark, impression, and then seriously restrict high-quality
The increased quality of cold-reduced sheet；In hot rolling production process, though the volatilization of rolled lubricating oil is unlikely to cause product quality defect, no
Cross also influences equipment to a certain extent uses.
Currently, most rolling lines periodically remove greasy dirt using movable type cleaning agent trolley and hand-held spray guns manually,
This method generally requires after roll extraction, and hand-held high-pressure spray gun is gradually rinsed the interior or exterior space of mill housing.It is cold
Milling train group washing time needs 1-3 hours or so, and washing time is long, needs to extend down time accordingly, influences subsequent life
It produces；Simultaneously because hand-held high-pressure nozzle is cleaned, there are some potential safety problemss, and cleaning agent cannot be heated to higher temperatures
Degree, causes cleaning effect unsatisfactory.In continuous production process, when occurring, the accident conditions needs such as piling of steel, disconnected band are unplanned
When roll change, although there is cleaning demand, but due to the time is more nervous, do not have cleaning condition generally, therefore, subsequent product holds

It is connected in the rotating hydraulic cylinder in self-cleaning mechanism, the rotating hydraulic cylinder in self-cleaning mechanism can drive rotary-cleaning spraying head
It rotates a certain angle, so that each self-cleaning mechanism is continuously finished greasy dirt cleaning function in a certain range, and pass through confession
Water hose provides certain spinning movement space.
（5）Rotary-cleaning spraying head in the present invention can assemble the spray head of different openings angle, according to rotary-cleaning spraying head
Different spray heads are selected from the location status in face to be cleaned, and form the cleaning water flow of different angles, such as opposite narrow jet stream
With wide jet stream.
（6）Rotary-cleaning spraying head in the present invention can be controlled by cleaning agent pump group and valve group, form pulsed injection,
Increase cleaning effect.
（7）Cleaning pump group in the present invention can heat cleaning agent, and heating temperature can achieve 60 DEG C or more, into
One step improves the cleaning effect of cleaning agent.
（8）The present invention can be cleaned in the period of the unplanned property parking roll change such as piling of steel, disconnected band, increase cleaning
Frequency.
The beneficial effects of the invention are as follows：It can be asked during normal production, reducing product quality caused by greasy dirt steam drippage
Topic, plan cleaning when, increase cleaning effect, save scavenging period, eliminate safe hidden trouble, and can unplanned parking gap into
The automatic cleaning of row, avoids subsequent hidden danger of quality.And the present invention is transformed on existing equipment, invests smaller, structure letter
It is single, compact, there is good popularizing value.
