UC planisher purging system present situation:
1, the former design of UC planisher purging system:
1.1 main purging component present situation
Main purging component is in planisher working roll (WR) roll gap place.The purging angle of purging portion is respectively 31 ° and 45 ° up and down; Purging portion blow gun number is respectively 11 and 13 up and down; Respectively to roller end both sides deflection, the blow gun angle of deviation is respectively 65 ° and 25 ° to blow gun up and down by the centre.Last purging portion is special cavity body structure, and compressed air twines gas collection in the airtight cavity of guide plate anti-, and the blow gun by front end forms the air curtain of expansion along roll gap to both sides together at WR roll gap place again.The anti-guide plate that twines of this structure has played the anti-dual-use function that twines and purge.As shown in Figure 1 and Figure 2.
Prevent that twining the guide plate stroke is accurately measured by displacement transducer, PLC (PLC programmable logic controller (PLC), i.e. programme-control) control, level reach under hydraulic cylinder promotes, head and last WR roll surface keep the gap value of 2mm.The purging high pressure draught forms one air curtain when passing this gap and plays the sealing gland effect, has stoped guide plate top and the smooth liquid of roll surface to drip from air gap.
1.2 auxiliary purging component present situation
Auxiliary purging component is between vibration-resistant roller and the outlet pass line roller roller, with the main spacing that purges 500mm is only arranged, and purges in order to strengthen smooth liquid.For alleviating auxiliary purging component to the influence of main purging component and reducing air consumption, so this road purging generally is in closed condition only as assisting purging component designing initially, standby to do.Last purging is " V " type special construction, can more effectively enlarge the purging scope, suppresses bandwidth roll gap in addition and carries raffinate, as shown in Figure 3.
1.3 intermediate calender rolls (IR) purging component present situation

1.4 strip edge portion purging component present situation
It is in order to eliminate the residual smooth liquid of strip edge portion that parts are blown on the limit.The limit is blown by " C " shape pipe 4-1 two parts of WS side and DS side and is formed, and concrete parts are chain pitch wheel and encoder 4-2, lower platen 4-3, and 4-4 drives hydraulic cylinder, positioning and guiding bar 4-5, upperpush rod 4-6, blow gun 4-7.By PLC control Driven by Hydraulic Cylinder lower platen 4-3, drive the chain drive top board again, dual-side is blown do relative equidistance motion.Change with bandwidth and accurately to be positioned the position of the 55mm of strip edge portion by encoder 4-2 (position=bandwidth-110mm) is blown on the limit, and offset correction (precision 20mm) is set, and realizes that online timely trace regulates, as shown in Figure 4.
At present, UC planisher purging system effect and existing problem:
2030 newly-increased companies were moved back the machine unit, and since going into operation on December 15th, 2009, smooth purging system function all drops into as scheduled by former design, and the smooth liquid mottling of initial stage belt steel surface of going into operation takes place frequently, and mainly shows:
1) the smooth liquid mottling of the random ellipticity of upper surface discontinuity, coin is to goose egg size;
2) the smooth liquid mottling of the vertical dirty wire of upper surface continuity;
3) the smooth liquid mottling of the random fragmentary droplet-like of lower surface, size is at 1cm2-4cm2;
4) the wide smooth liquid water mark of the 10mm-40mm of strip edge portion;
5) the upper surface disperse smooth liquid mottling of tiny point-like that distributes;
By the deep analysis to the pattern of smooth liquid mottling, distribution situation, degree, in conjunction with the present situation that the purges key point that searches problem, the smooth liquid mottling of analysis-by-synthesis mechanism of production.Specific as follows:
1) the smooth liquid mottling of the random ellipticity of upper surface discontinuity produces reason.
Being mainly planisher outlet dropping liquid causes.The formation of drop mainly is owing to the smooth liquid that is heated to 25-40 ℃ is condensed into drop easily after purging atomizing.Through observing dropping liquid point position three places are arranged: anti-guide plate head, afterbody crossbeam and the guide plate lower surface of twining.Through observation analysis, because the anti-guide plate head design that twines is unreasonable, and and air gap and the sealing gland uniformity of 2mm can not be guaranteed between the roll surface, throws a large amount of raffinates spatter between upper roll and do not collect eliminating, causes smooth liquid raffinate to twine the guide plate head and body of roll gap drops onto belt steel surface from anti-.Anti-twine the drop that side space and afterbody crossbeam condense under the guide plate and in time collect discharging, and in outlet smooth liquid baffle plate is not installed, cause smooth liquid to pass the outlet device space and be splashed to belt steel surface.
2) the smooth liquid mottling of the vertical dirty wire of upper surface continuity produces reason.
Mainly be because IR purging portion fails effectively to eliminate the smooth liquid that roll surface sticks, after roll surface circumferentially forms wide strip mottling, copy to belt steel surface by WR, form dirty line.
3) reason of the smooth liquid mottling generation of the random fragmentary droplet-like of lower surface.
Under purge tracheae base support hydrops, under the purging effect, gyration airflow blows afloat the part hydrops and is splashed to band steel lower surface.
4) the generation reason of the smooth liquid water of strip edge portion mark.
The angle of purging component is non-adjustable, the purging scope is narrower, purging power deficiency because blow on the limit; Secondly, to blow fine setting 20mm offset compensation positioning accuracy low on the limit.In addition, purging point does not up and down concentrate on the same position.
5) the upper surface disperse smooth liquid mottling of tiny point-like that distributes produces reason.
Owing to purge smooth liquid raffinate particle enrichment that the atomizing back produces in planisher outlet small space, when the temperature difference is big, condenses into fine drop and be attached to band steel upper surface and form the disperse smooth liquid mottling of tiny point-like that distributes.
