1.Dab tsi yog cov kev cai dav dav tswj xyuas qhov tseeb?
High-cov dov mills (xws li Sendzimir mills thiab siab heev rau - siab mills rau ua ultra- nyias strip los yog silicon steel):
Qhov tseeb qhov tseeb: ± 0.3% ~ ± 0.5%.
Dynamic raug (acceleration / deceleration, threading txheej txheem): Controllable nyob rau hauv ± 1%.
Qhov no yuav tsum muaj lub siab -kev ua tau zoo hydraulic servo system, siab - teb tsav lub cev muaj zog, siab - qhov ntsuas qhov ntsuas qhov tseeb, thiab cov qauv tswj siab heev.
Ib qho yooj yim ib leeg- sawv ntsug / ntau- sawv ntsug txias nruam dov mills (tsim carbon steel, khoom vaj huam sib luag, thiab lwm yam.):
Qhov tseeb qhov tseeb: ± 0.8% ~ ± 1.5%.
Qhov no yog feem ntau ua tiav qib uas ua tau raws li qhov xav tau ntawm cov khoom siv feem ntau.
Cov laus dua lossis tsawg dua xav tau dov mills:
Qhov tseeb tsuas yog khaws cia tsis pub dhau ± 2% ~ ± 3% lossis txawm tias dav dua, uas feem ntau ua rau muaj qhov sib txawv ntawm cov thickness thiab cov teeb meem zoo.
2.Dab tsi yog yam tseem ceeb cuam tshuam rau qhov tseeb ntawm kev tswj nruj?
Qhov tseeb ntawm Kev Tshawb Fawb Cheeb Tsam:
Tensile Gauge: Cov tub ntxhais sensor. Siab -precision strain gauge lossis piezomagnetic tensile gauges yuav tsum muaj qhov ntsuas qhov tseeb zoo dua ± 0.25%. Lawv qhov chaw installation, calibration, thiab txij nkawm yog qhov tseem ceeb.
Encoder: Siv los ntsuas yob txoj kab uas hla thiab linear ceev; nws qhov kev daws teeb meem ncaj qha cuam tshuam rau kev suav nro.
Actuator Teb Ceev:
Winder/Unwinder Motor: Yuav tsum yog vector-tswj AC lossis DC lub cev muaj zog nrog cov lus teb ceev ceev.
Looper: Nyob rau hauv tas li dov mills, lub looper yog ib tug tseem ceeb ntaus ntawv rau buffering thiab regulating nro; cov lus teb ceev ntawm nws cov hydraulic lossis hluav taws xob system ncaj qha cuam tshuam rau kev ruaj ntseg ntawm qhov nro ntawm qhov sawv.
Tswj System Level:
Tswj Algorithm: Kev tswj PID tsoos tsis txaus. Cov rolling mills niaj hnub no feem ntau siv cov txheej txheem siab tshaj plaws xws li kev tswj hwm kev tswj hwm, kev tswj hwm kev tswj hwm, kev tswj fuzzy, lossis kev sib txuas hauv nruab nrab los kwv yees thiab them nyiaj rau kev cuam tshuam thaum dov (xws li kev hloov ceev, kev hloov pauv tam sim ntawd, thiab hloov pauv hauv kev sib txhuam coefficient).
Kev sib koom ua ke thiab kev sib txuas lus: Ua tiav digital, siab - kev sib txuas lus hauv tsheb npav ceev (xws li EtherCAT) ua kom muaj kev sib txuas thiab qeeb - cov teeb liab dawb ntawm cov tswj thiab cov sensors.
3.Dab tsi yog qhov tshwm sim ntawm qhov tsis txaus siab tswj precision?
Thickness sib txawv: Ntxoov yog qhov tseem ceeb tshaj plaws cuam tshuam rau dov quab yuam thiab yog li thickness. Kev sib hloov ntawm qhov nro ua rau longitudinal thickness variations.
Strip shape defects: Xws li waviness, warping, thiab tapered coils. Tsis sib npaug los yog tsis ruaj tsis khov yog ib qho ntawm cov laj thawj tseem ceeb ntawm txoj hlua tsis zoo.
strip misalignment thiab breakage: tsis sib npaug ntawm ob sab tuaj yeem ua rau strip misalignment; Kev nruj nruj heev tuaj yeem ua rau cov kab nrib pleb yooj yim tawg, thaum tsis txaus nro tuaj yeem ua rau khaws cia lossis folding.
Qhov zoo ntawm qhov chaw: Tsis ruaj khov nro tuaj yeem ua rau slippage ntawm cov yob thiab cov sawb, ua rau muaj kev vibration los yog khawb.
4.Qhov raug ntsuas thiab txheeb xyuas li cas?
Kev tswj nruj nruj yog feem ntau kuaj thiab ntsuas raws li cov hauv qab no:
Qhov kev hloov pauv hloov thaum lub sijhawm khov kho- lub xeev tas li- nrawm nrawm.
Qhov siab tshaj plaws sib txawv thiab rov qab lub sij hawm thaum acceleration thiab deceleration.
Tswj lub peev xwm thaum threading thiab tail -wagging.
5.Dab tsi yuav tsum tau txiav txim siab thaum tswj qhov nro ntawm txias -rolled coils?
Kev tswj nruj nruj hauv qhov txias- dov coils yog ib qho ntawm cov kev sib tw tseem ceeb ntawm cov tshuab txias txias niaj hnub. ± 1% tuaj yeem suav hais tias yog lub sijhawm dej ntws, qhov taw qhia tseem ceeb sib txawv ntawm nruab nrab - mus rau siab - kawg mills. Kev ua tiav thiab tswj xyuas qhov tseeb siab yuav tsum muaj kev sib xyaw ua ke zoo tshaj plaws ntawm siab - kev paub meej, siab - nrawm nrawm, thiab kev tswj xyuas ntse.
Rau cov neeg ua haujlwm tsim khoom thiab cov kws tshaj lij, kev nkag siab txog lub hom phiaj tus nqi thiab cuam tshuam rau kev tswj xyuas qhov tseeb yog qhov tseem ceeb rau kev tu cov cuab yeej siv, kev ua kom zoo dua qub, thiab kuaj qhov teeb meem. Thaum cov teeb meem thickness los yog cov duab tshwm sim, lub xeev ntawm qhov nro system feem ntau yog thawj qhov chaw los tshawb xyuas.
