1. Txheej txheem cej luam ntawm cov khoom pickled: Pickled steel daim hlau yog ua los ntawm kub dov steel coils. Tom qab pickling, qhov zoo ntawm qhov chaw thiab siv cov kev cai ntawm pickled steel daim hlau yog cov khoom nruab nrab ntawm kub-dov hlau phaj thiab txias-kuav los tiag steel daim hlau. Piv nrog rau cov ntawv kub-dov hlau, qhov zoo ntawm cov phaj hlau pickled yog feem ntau: zoo nto zoo, siab qhov tseeb, txhim kho nto tiav, txhim kho cov nyhuv zoo, thiab txo cov pa phem ib puag ncig los ntawm cov neeg siv khoom dispersed pickling. Tsis tas li ntawd, piv nrog cov khoom kub-dov, cov khoom siv tau yooj yim dua rau vuam vim tias cov nplai oxide tau raug tshem tawm, thiab tseem muaj txiaj ntsig zoo rau kev kho deg xws li roj thiab pleev xim. Feem ntau, cov qib zoo ntawm cov khoom kub dov yog FA, cov khoom qab zib yog FB, thiab cov khoom txias dov yog FB / FC / FD. Pickled khoom tuaj yeem hloov cov khoom txias-dov los ua qee yam qauv, uas yog, cua sov hloov txias.

2. Tej yam tsis xws luag ntawm pickled steel daim hlau:
Qhov tsis xws luag ntawm cov hlau phaj hauv nws cov txheej txheem tsim khoom yog feem ntau: oxide scale indentation, oxygen me ntsis (nto moo toj roob hauv pes painting), duav quav (kab rov tav fold print), khawb, daj me ntsis, under-pickling, over-pickling, thiab lwm yam. Nco tseg: Cov kev tsis sib haum xeeb yog txuas nrog cov kev cai ntawm cov qauv lossis cov kev pom zoo tsuas yog cov uas tsis ua raws li qhov yuav tsum tau hu ua qhov tsis xws luag.
2.1 Iron oxide scale indentation: Hlau oxide nplai indentation yog ib qho teeb meem saum npoo tsim thaum kub dov. Tom qab pickling, nws yog feem ntau nias nyob rau hauv daim ntawv ntawm cov dots dub los yog ntev strips, nrog ib tug ntxhib nto, feem ntau nrog ib tug txhais tes xav, thiab tshwm sporadically los yog ntom.
Qhov ua rau cov hlau oxide nplai muaj feem xyuam rau ntau yam, feem ntau yog cov hauv qab no: cov cua sov hauv cov cua kub cua sov, cov txheej txheem descaling, txheej txheem dov, cov khoom yob, thiab lub xeev, lub xeev cov menyuam, thiab cov phiaj xwm dov.
Tswj kev ntsuas: Ua kom zoo rau cov txheej txheem cua sov, ua kom cov descaling hla dhau, thiab tsis tu ncua xyuas thiab tswj cov menyuam thiab cov menyuam, kom cov kab dov tau khaws cia rau hauv qhov chaw zoo.
2.2 Oxygen me ntsis (sab saum toj toj roob hauv pes painting defects): Oxygen chaw tsis xws luag yog hais txog lub dot-puab, kab-puab, los yog pit-shaped morphology sab laug tom qab cov hlau oxide teev nyob rau saum npoo ntawm lub kub kauj yog ntxuav tawm. Visually, nws zoo nkaus li tsis meej xim txawv me ntsis. Vim tias cov duab zoo ib yam li toj roob hauv pes painting, nws tseem hu ua toj roob hauv pes painting defect. Visually, nws yog ib tug maub qauv nrog undulating ncov, uas yog muab faib raws li ib tug tag nrho los yog ib feem ntawm lub nto ntawm lub sawb steel phaj. Nws yog ib qho tseem ceeb ntawm oxidized hlau nplai stain, uas yog ib txheej ntawm cov khoom ntab saum npoo, tsis muaj qhov kov, thiab tej zaum yuav tsaus dua los yog sib dua ntawm cov xim. Qhov tsaus ntuj yog qhov ntxhib heev, thiab muaj qee yam cuam tshuam rau cov tsos tom qab electrophoresis, tab sis tsis cuam tshuam rau kev ua haujlwm.
Ua rau ntawm cov pa oxygen (cov duab kos duab tsis xws luag): Lub ntsiab lus ntawm qhov tsis xws luag yog qhov oxidized hlau nplai ntawm qhov kub-kuav los tiag strip tsis tau tshem tawm tag nrho, thiab nias rau hauv matrix tom qab dov tom qab, thiab sawv tawm tom qab pickling. .
Tswj kev ntsuas rau cov pa oxygen: txo cov hlau tapping kub ntawm cov cua kub cua sov, ua kom cov xov tooj ntawm cov rolling descaling hla dhau, thiab ua kom zoo tshaj qhov ua tiav cov txheej txheem dej txias.
2.3 Lub duav quav: Lub duav quav yog ib qho kev sib tw, khoov, lossis thaj chaw rheological perpendicular mus rau qhov kev taw qhia dov. Nws tuaj yeem txheeb xyuas qhov muag liab qab thaum unrolling, thiab nws tuaj yeem hnov ​​​​los ntawm tes yog tias nws hnyav heev.
Ua rau lub duav quav: Tsawg-carbon aluminium-tua steel muaj lub hauv paus yield platform. Thaum cov hlau kauj yog unrolled, cov txiaj ntsig deformation tshwm sim nyob rau hauv qhov kev txiav txim ntawm dabtsi yog khoov kev ntxhov siab, uas hloov lub qub qub khoov mus rau hauv ib qho tsis sib xws, uas ua rau lub duav quav.
2.4 Cov pob daj daj: Cov pob daj tshwm rau ntawm ib feem ntawm cov sawb lossis tag nrho cov hlau phaj saum npoo, uas tsis tuaj yeem npog tom qab oiling, cuam tshuam rau cov khoom zoo.
Ua rau cov pob daj daj: Cov kev ua haujlwm saum npoo ntawm cov sawb tsuas yog tawm ntawm lub tank pickling yog siab, cov dej yaug tsis ua lub luag haujlwm ntawm ib txwm yaug cov sawb, thiab qhov saum npoo ntawm cov sawb yog oxidized thiab yellowed; cov kab tsuag tsuag thiab lub nozzle ntawm lub tank rinsing yog thaiv, thiab cov ces kaum tsis sib npaug.
Kev tswj kev ntsuas rau cov xim daj yog: tsis tu ncua xyuas cov xwm txheej ntawm cov kab tsuag tsuag thiab lub nozzle, ntxuav lub nozzle; kom ntseeg tau lub siab ntawm cov dej yaug, thiab lwm yam.
2.5 Kos: Muaj qee qhov tob ntawm khawb ntawm qhov chaw, thiab cov duab tsis zoo, uas cuam tshuam rau qhov zoo ntawm cov khoom.
Ua rau khawb: lub voj tsis zoo; hnav cov nylon hauv ob sab phlu; cov duab tsis zoo ntawm cov phaj steel tuaj; xoob coiling ntawm lub nplhaib puab ntawm kub kauj, thiab lwm yam.
Tswj kev ntsuas rau khawb: 1) Ua kom qhov nro ntawm lub voj kom tsim nyog; 2) Tshawb xyuas qhov xwm txheej ntawm lub liner tsis tu ncua, thiab hloov lub liner nrog qhov txawv txav ntawm lub sijhawm; 3) Kho cov xaim hlau xaim nrog cov phaj tsis zoo thiab xoob puab lub nplhaib.
2.6 Hauv qab-pickling: Lub npe hu ua under-pickling txhais tau hais tias lub zos hlau oxide nplai nyob rau saum npoo ntawm lub sawb tsis raug tshem tawm kom huv si thiab txaus, lub phaj steel nto yog grey-dub, thiab muaj ntses nplai lossis kab rov tav dej ripples. .
Ua rau hauv qab-pickling: Qhov no muaj feem xyuam rau cov txheej txheem ntawm cov kua qaub thiab qhov chaw ntawm cov hlau phaj. Cov txheej txheem kev tsim khoom tseem ceeb suav nrog cov kua qaub tsis txaus, tsis muaj qhov kub thiab txias, nrawm nrawm nrawm nrawm, thiab cov sawb tsis tuaj yeem tso rau hauv cov kua qaub. Lub thickness ntawm kub kauj hlau oxide nplai yog tsis sib npaug, thiab cov hlau kauj muaj yoj duab. Hauv qab-pickling feem ntau yog yooj yim tshwm sim ntawm lub taub hau, tus Tsov tus tw, thiab ntug ntawm lub sawb.
Tswj kev ntsuas rau hauv qab-pickling: kho cov txheej txheem pickling, optimize cov txheej txheem kub dov, tswj cov sawb zoo, thiab tsim kom muaj cov txheej txheem tsim nyog.
2.7 Tshaj-pickling: Tshaj-pickling txhais tau tias tshaj-pickling. Qhov saum npoo ntawm cov sawb feem ntau yog xim dub los yog xim av-dub, nrog cov blocky los yog flaky dub los yog daj me ntsis, thiab saum npoo ntawm steel phaj feem ntau ntxhib.
Ua rau over-pickling: Contrary to under-pickling, over-pickling yog ib qho yooj yim tshwm sim yog cov kua qaub concentration siab, kub siab, thiab txoj siv ceev ceev yog qeeb. Qhov tshaj-pickling cheeb tsam yuav tsum muaj feem ntau tshwm sim nyob rau hauv nruab nrab thiab dav ntawm lub sawb.
Tswj kev ntsuas rau ntau tshaj-pickling: Kho thiab ua kom zoo rau cov txheej txheem pickling, tsim kom muaj cov txheej txheem tsim nyog, thiab ua kom muaj kev cob qhia zoo los txhim kho qib kev tswj hwm zoo.

3. Kev nkag siab txog kev tswj xyuas zoo ntawm cov khoom siv pickled steel strips
Piv nrog kub-kuav los tiag steel strips, pickled steel strips tsuas muaj ib tug ntxiv pickling txheej txheem. Nws yog feem ntau ntseeg tias nws yuav tsum yooj yim dua los tsim cov hlau nplaum uas tsim nyog. Txawm li cas los xij, kev xyaum qhia tau hais tias kom ntseeg tau tias cov khoom lag luam pickled zoo, tsis yog tsuas yog cov kab pickling yuav tsum muaj qhov zoo, tab sis kuj tseem muaj cov txheej txheem tsim khoom thiab kev ua haujlwm ntawm cov txheej txheem dhau los (steelmaking thiab kub dov txheej txheem) yuav tsum ruaj khov kom zoo. ntawm cov khoom siv kub-dov tuaj yeem lav tau. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua raws li kev tswj hwm zoo ib yam los xyuas kom meej tias qhov zoo ntawm txhua tus txheej txheem yog nyob rau hauv ib txwm lub xeev los xyuas kom meej qhov zoo ntawm cov khoom kawg.
