1. Pfupiso yezvigadzirwa zvakabikwa: Pickled simbi mahwendefa anogadzirwa nemoto-akakungurutswa esimbi makoiri. Mushure mekunhonga, kunaka kwepamusoro uye kushandiswa kwezvinodiwa zvemapuleti esimbi zvakasanganiswa zvigadzirwa zvepakati pakati pemarata anopisa akakungurutswa nesimbi inotonhora. Zvichienzaniswa nemarata anopisa akakungurutswa esimbi, zvakanakira simbi yakanyungudutswa zvinonyanya: kunaka kwepamusoro, kurongeka kwepamusoro-soro, kukwidziridzwa kwepamusoro, kukwidziridzwa kutaridzika, uye kuderedzwa kusvibiswa kwezvakatipoteredza kunokonzerwa nemushandisi-akapararira pickling. Pamusoro pezvo, zvichienzaniswa nezvigadzirwa zvinopisa zvakakungurutswa, zvigadzirwa zvema pickled zviri nyore kupinza nekuti chiyero che oxide chakabviswa, uye zvakare chinobatsira pakurapwa kwepamusoro sekuzora mafuta nekupenda. Kazhinji, giredhi remhando yepamusoro yezvigadzirwa zvinopisa-zvinopisa iFA, zvigadzirwa zvakanyungudutswa iFB, uye zvigadzirwa zvinotonhora-zvinoita FB/FC/FD. Zvigadzirwa zvepickled zvinogona kutsiva zvigadzirwa zvinotonhora kuti zvigadzire zvimwe zvimiro, ndiko kuti, kupisa kunotsiva kutonhora.

2. Kukanganisika kwakajairika kwemahwendefa esimbi akabikwa:
Kukanganisa kwakajairika kwesimbi yakanyungudutswa mahwendefa mukugadzira kwayo kwakanyanya: oxide sikeri indentation, nzvimbo dzeokisijeni (kupendiwa kwepasi), kupeta chiuno (kupeta kwakachinjika), makwapa, makwapa eyero, pasi-pickling, kunyanya-kunhonga, nezvimwe. ( Cherechedzo: Kukanganisa kwakabatana nezvinodiwa zvezviyero kana zvibvumirano chete izvo zvisingazadzise zvinodiwa zvinodaidzwa kuti kurerukirwa kwekutaura, kukanganisa kunoshandiswa pano kutsiva imwe mhando yechimiro.
2.1 Iron oxide scale indentation: Iron oxide scale indentation is a surface defect inoumbwa panguva inopisa inopisa. Mushure mekunhonga, inowanzo kudzvanywa muchimiro chemavara matema kana mitsetse yakareba, ine hutsinye hwepamusoro, kazhinji neruvoko rwekunzwa, uye inoratidzika pano neapo kana kuti dense.
Izvo zvinokonzeresa iron oxide scale zvine chekuita nezvakawanda zvinhu, kunyanya zvinotevera zvinhu: kudziyisa muchoto chekudziya, kudzika nzira, rolling process, roll material, uye nyika, roller state, uye rolling plan.
Kudzora matanho: Kururamisa nzira yekudziya, kuwedzera huwandu hwekudzikisa pasi, uye gara uchitarisa uye chengetedza roller uye roller, kuitira kuti mutsara wekutenderera uchengetedzwe mune zvakanaka.
2.2 Oxygen spots (surface landscape paint defects): Kukanganiswa kweoxygen spots kunoreva morphology yakaita dot, yakaita mutsara, kana gomba mushure mekunge sikero ye iron oxide iri pamusoro pekoiri inopisa yasukwa. Pakuona, zvinoita sezvisina kujairika mavara akasiyana mavara. Nekuda kwekuti chimiro chakafanana nependi yenzvimbo, inodaidzwa zvakare kunzi landscape pendi defect. Zvitarisiko, imhando yakasviba ine nhongonya dzisina kudzika, inogovaniswa zvakazara kana kuti zvishoma pamusoro peiyo strip steel plate. Icho chakanyanya oxidized iron scale stain, inova musara wezvinhu zvinoyangarara pamusoro, pasina chekubata, uye inogona kusviba kana kureruka muruvara. Chikamu cherima chinenge chakashata, uye chine chimwe chinokanganisa pakuonekwa mushure me electrophoresis, asi haikanganisi kushanda.
Chikonzero chemavara eokisijeni (kukanganisa pendi yepasi): Chakanyanya chehurema iyi ndechekuti chiyero chesimbi chine oxidized pamusoro peiyo inopisa-yakakungurutswa tambo haina kubviswa zvachose, uye inotsikirirwa mumatrix mushure mekukunguruka kwakatevera, uye inomira kunze mushure mekunhonga. .
Kudzora matanho enzvimbo dzeokisijeni: kuderedza tembiricha yekupopa kwesimbi yechoto chekudziya, wedzera huwandu hweakaomesesa anotenderedza ekudzikisa pasi, uye shongedza yekupedzisa kutenderedza kutonhora nzira yemvura.
2.3 Kupeta chiuno: Kupeta chiuno kuchinjika, kukotama, kana rheological zone perpendicular kune inotenderera nzira. Rinogona kuonekwa neziso rakashama kana richidzururwa, uye rinogona kunzwikwa nemaoko kana ranyanya.
Zvikonzero zvekupeta chiuno: Yakaderera-kabhoni aruminiyamu-yakauraya simbi ine yekuzvarwa goho chikuva. Kana iyo coil yesimbi yakavhurwa, iyo goho deformation mhedzisiro inoitika pasi pechiito chekukotama kushushikana, izvo zvinoshandura iyo yekutanga yunifomu bend kuita isina kuenzana bend, zvichikonzera kupeta chiuno.
2.4 Yellow spots: Yero makwapa anoonekwa pachikamu chemutsetse kana pese pendi yesimbi, isingavharwe mushure mekuzora mafuta, zvichikanganisa kutaridzika kwemhando yechigadzirwa.
Zvinokonzera makwapa eyero: Kuitwa kwepamusoro pemutsetse uchangobva mutangi rekunhonga kwakakwira, mvura yekusukurudza inotadza kuita basa rekugezesa kwekanguva kwetambo, uye pamusoro pemutsetse wacho pane oxidized uye neyero; danda rekupfapfaidza uye muromo wetangi rekusuka zvakavharwa, uye makona haana kuenzana.
Matanho ekudzora eyero mavara ndeaya: kugara uchitarisa mamiriro eiyo spray danda uye nozzle, kuchenesa muromo; kuve nechokwadi chekumanikidzwa kwemvura yekusuka, nezvimwe.
2.5 Scratches: Kune humwe hudzamu hwekukwenya pamusoro, uye chimiro hachina kurongeka, izvo zvinokanganisa kunaka kwechigadzirwa.
Zvikonzero zvekukwenya: kusagadzikana loop tension; kupfeka kwenylon lining; chimiro chisina kunaka cheplate yesimbi inouya; yakasununguka coiling yemukati mhete ye inopisa coil, nezvimwe.
Kudzora matanho ekukwenya: 1) Wedzera kushushikana kwechiuno zvakakodzera; 2) Tarisa mamiriro ekunze emutsetse nguva dzose, uye shandura iyo liner neabnormal surface condition in time; 3) Gadzirisa coil yesimbi inopinda ine chimiro chisina kunaka cheplate uye yakasununguka mhete yemukati.
2.6 Kunhonga pasi: Iyo inonzi under-pickling inoreva kuti iron oxide yemuno iri pamusoro pemutsetse haina kubviswa zvakachena uye zvakakwana, simbi yeplate pamusoro igrey-black, uye kune makwande ehove kana maburi emvura akachinjika. .
Zvinokonzera pasi-pickling: Izvi zvine chekuita nemaitiro eiyo acid mhinduro uye mamiriro epamusoro esimbi ndiro. Iyo huru yekugadzira maitiro zvinhu zvinosanganisira kusakwana kweasidhi yekumisikidza, yakaderera tembiricha, yakanyanyisa tambo yekumhanya kumhanya, uye tambo haigone kunyudzwa mumhinduro yeasidhi. Ukobvu hweiyo inopisa coil iron oxide scale haina kuenzana, uye coil yesimbi ine wave wave. Under-pickling inowanzova nyore kuitika kumusoro, muswe, uye kumucheto kwemutsetse.
Kudzora matanho ekuchera pasi-kunhonga: gadzirisa maitiro ekunhonga, gadzirisa kupisa kutenderedza maitiro, dzora chimiro che strip, uye gadza inonzwisisika process system.
2.7 Kunonga zvakapfurikidza: Kunonga zvakapfurikidza zvinoreva kudzvara. Kumusoro kwemutsetse kunowanzo kusviba dema kana shava-dema, iine makwapa akavharika kana anotsemuka matema kana yeyero, uye pamusoro pesimbi ndiro inowanzoita hutsinye.
Zvinokonzeresa kunhonga zvakanyanya: Kusiyana nekunhonga-nhonga, kudzvanya kuri nyore kuitika kana iyo acid yakakwira, tembiricha yakakwira, uye kumhanya kwebhandi kunononoka. Iyo yakanyanyisa-pickling nzvimbo inofanira kunge yakanyanya kuoneka pakati nehupamhi hwemutsetse.
Kudzora matanho ekunhonga zvakanyanya: Gadzirisa uye gadzirisa maitiro ekunhonga, gadza yakakodzera maitiro sisitimu, uye ita kudzidziswa kwemhando yekuvandudza nhanho yekutonga.

3. Kunzwisisa kwehutano hwehutano hwepickled steel strips
Kuenzaniswa nematare anopisa-akakungurutswa simbi, pickled simbi mitsetse chete imwe chete pickling process. Zvinotendwa kuti zvinofanirwa kuve nyore kugadzira simbi yakanyungudutswa ine hunhu hwakakodzera. Nekudaro, kudzidzira kunoratidza kuti kuve nechokwadi chemhando yezvigadzirwa zvakabikwa, kwete chete mutsara wepickling unofanirwa kunge uri mumamiriro akanaka, asiwo kugadzirwa uye mamiriro ekushanda kweiyo yapfuura maitiro (steelmaking uye inopisa rolling process) inofanira kuchengetedzwa yakagadzikana kuitira kuti mhando. yezvinhu zvinopisa zvinopisa zvinopinda zvinogona kuvimbiswa. Naizvozvo, zvinodikanwa kuomerera kune inopindirana yemhando yekutarisira nzira kuti ive nechokwadi chekuti mhando yeimwe neimwe nzira iri mune yakajairika mamiriro kuti ave nechokwadi chemhando yechigadzirwa chekupedzisira.
