Description

The online high efficiency blow device of a kind of Cold-Rolled Strip Temper Mill
Technical field
The utility model relates to the online high efficiency blow device of a kind of Cold-Rolled Strip Temper Mill, and it is a kind of in cold-rolled process, utilizes the instrument of airflow cleans surface of cold-rolled steel plate residual liquid, belongs to Cold-Rolled Strip Temper Mill and cleans online field.
Background technology
Along with metallurgical industry is to product yield, what the continuity of producing required improves constantly, rolled piece purging system efficient stable has also been proposed to more and more higher requirement, tradition cold-rolling continuous annealing unit is owing to purging beam position, spray angle, the factors such as injector spacing arranges that there is the residual and macula lutea of the smooth liquid of obvious strip in the unreasonable plate face limit portion that causes, at present only from the service condition of purge nozzle, what top working roll and upper backup roll roll gap purged original design and employing is the nozzle of the 705+PSK12 series of certain external famous brand name, 705 nozzles are in the actual purging coverage 150mm being not less than under 6BAR pressure, and on-the-spot actual 705 nozzles need to be in 400mm left and right to the purging distance of roll gap, thereby cannot block live roll gap at all, because plate width is less than working roll width, working roll two ends will be gapped, smooth liquid can be brought on backing roll along with working roll, in the middle of after backing roll rotates, can form negative pressure band, the smooth liquid of limit portion collects to centre, if the smooth liquid that limit portion is not lived in block collects to centre, having smooth drop falls in strip, thereby can only increase roll gap purge nozzle purging pressure, so will form the effect bad with backing roll block when injector configuration is unreasonable, can directly affect strip quality, top working roll and upper strip roll gap purge, it is topmost purging point that this road purges, from our a large amount of practical application example, sum up out, this purges together and must purge by whole working roll roll gap.On-the-spot actual amount delivery nozzle is 350mm to the distance of roll gap, that adopt is 705 nozzles+PSK12,705 nozzles are in the actual purging coverage 150mm being not less than under 6BAR pressure, nozzle cannot block arrive roll gap, will cause so a large amount of smooth liquid to take in outlet side strip along with the gap at the both ends of strip, be brought on backing roll simultaneously, cause a large amount of smooth liquid of strip limit portion to blow off in time.The strip of high-speed mobile can make to have in the larger width range of strip limit portion residual under the effect of acceleration, bottom working roll and strip roll gap purge, it is the same that this road purges the same roll gap purging importance, the nozzle model of installing at present purges the same with upper roll gap, the problem showing is the same, on, lower face purges, on, it is that a small amount of smooth liquid after removing roll gap above and purging is residual that lower strip purges Main Function, need whole plate face to cover, but former design only has two nozzles of limit portion, after blowing to above memorial archway, strip middle rebounds on strip like this, cause the residual of strip.
Before transformation, have only improve to purge pressure and adopt 710 large purging power, the nozzle that far purges coverage seals roll gap completely and just can make a large amount of smooth liquid cannot be thrown to outlet side, make limit portion less residual and by a procedure below, upper strip purges and limit portion purges completely and removes.Adopt in the use of ball-joint band nozzle and purge effect because the reasons such as vibration easily make nozzle angle variable effect.Often need to shut down and adjust nozzle angle.And nozzle does not have protector, threading and broken belt are just easy to break nozzle, because air consumption is large.Per hourly reach 5800 cubic meters/hour.
Through retrieval, Chinese patent CN200910249007.6 discloses < < emulsion cleaning device > > of Yizhong Group Dalian design Institute, this device is cold rolling unsatisfactory by on-site verification effect in tradition, purge unclean, Chinese patent also discloses CN200820230170.9 < < device for sweeping continuous slab band edge part > > and CN200720016060.8, CN201120296487.4, CN200720012650.3, CN200720073697.0, CN200920139979.5, CN200810236801.2 etc. are many similarly about emulsion, rolling mill compound, the patent that smooth liquid purges, take an overall view of these patents and on efficient stable, all can not reach current cold rolling high-quality Strip technological requirement, do not meet allegro consecutive production.
