1.What yog lub hom phiaj tseem ceeb ntawm kev rov ua dua cov khib nyiab cov khib nyiab xim?
Thawj qhov rov ua dua tus nqi ntawm seem xim-coated steel co dag nyob hauv lawv cov hlau subttrates (feem ntau galvanized steel, thiab txias-rolled steel). Lub hom phiaj tshaj plaws ntawm kev rov ua dua yog kom rov qab ua cov hlau ua cov hlau tshiab.
2.YHyas li tus txheej txheem smelting kho cov txheej?
Organic txheej txheem (resins, pigments, ntxiv): lawv yog decomposed tag nrho, vaporized, thiab hlawv. Cov cua sov tsim los ntawm lawv cov kev sib txuas ua ke tuaj yeem txawm hloov roj (albeit nyob rau hauv ib qho me me).
Cov Cheebtsam Inorganic (cov hlau oxides hauv cov pigments, fitters, thiab lwm yam):
Zinc / al-Zinc Castings: Zinc Volatilizes ntawm cov plua plav kom qhuav thiab yog cov plua plav tshem tawm (raws li zinc-muaj plua plav, uas tuaj yeem rov qab tau ntxiv). Txhuas oxidizes thiab nkag mus rau hauv kev swb lossis tseem nyob hauv cov hlau hauv cov nyiaj tsawg (feem ntau yog tsawg tsawg, nrog kev cuam tshuam me me).
Txoj hlab ntsha tsis muaj nqis rau tus nqi: kev fij tawm ntawm cov txheej txheej yog tus nqi, muaj txiaj ntsig uas yuav tsim cov chaw qias neeg thib ob (cov khoom siv tshuaj laus thiab tshem tawm cov khib nyiab theem nrab). Stripping txheej ci yog tsis muaj kev lag luam thiab tsis tsim nyog hauv lub ntsej muag ntawm kev kub siab smelting.
3.Qhov yog lwm txoj hauv kev los siv nws?
Kev siv hluav taws xob rau lub cev / kho kom zoo dua qub: yog qee cov khoom siv ua ntej, nws tuaj yeem siv sijhawm ntau dua (piv txwv li, nws qee zaum tau ntxuav ib ntus kom tshem tau cov hmoov xoob thiab av). Hauv cov rooj plaub no, stripping txheej yog tsis tsim nyog; Tsuas yog txoj kev xoob yuav tsum tau muab tshem tawm. ◦ Kev Tsim Lwm Yam Khoom Tsawg: Hauv qee zaus, nws yuav tau muab cov khoom siv tsis muaj chaw nyob lossis siv cov khoom siv uas tsis zoo, tab sis feem ntau khaws cov txheej. Stripping txheej txheej nce siab thiab tus nqi. ◦ coating rov ua dua tshiab thiab tsis paub qab): thaum nws yog qhov muaj txiaj ntsig ntawm cov khoom siv los ntawm cov khoom sib cais (piv txwv li tsis muaj peev xwm ua tau zoo thiab tsis muaj peev xwm, thiab cov khoom siv tsis muaj txiaj ntsig, thiab cov khoom siv tsis muaj txiaj ntsig, thiab cov khoom siv sib cais tsis muaj txiaj ntsig. Tam sim no, txoj hauv kev no tsis muaj cov ntawv thov kev lag luam tus nqi. Nws yog qhov nqi tsawg dua-ua tau zoo dua li rov ua dua cov hlau substrate.
4.Yog li cas yog lub tswv yim ntawm "Pufting tawm txheej" impractical thiab tsis pom zoo?
Kev nyuaj nyuaj: txheej yog nruj nreem rau lub substrate, tshwj xeeb tshaj yog cov txheej txheem zoo. Kev Stripping lub cev (xws li scraping thiab sib tsoo) yog qhov tsis muaj txiaj ntsig zoo thiab tuaj yeem ua rau cov hlau ua kom loj. Tshuaj stripping yuav tsum siv cov corrosive lossis cov kuab tshuaj organic, uas yog muaj nqi, txaus ntshai, yuav tsum muaj kev phom sij kom muaj kev phom sij tshwj xeeb uas yuav tsum muaj pov tseg tshwj xeeb.
Tsis zoo nyiaj txiag kev ua tau zoo: Cov nqi ntawm kev ua haujlwm stripping (ua haujlwm, cov khoom siv, thiab pov tseg khib nyiab) tuaj yeem ua kom ntev dua cov neeg hlau rov qab. Steel Mills Hloov Dua Scrap hlau raws li cov ntsiab lus hlau. Qhov sib txawv hauv tus nqi ntawm cov coated scrap xim-txheej coils thiab stripped cov txheej txheem huv (txij li cov txheej huv (txij li cov txheej huv (txij li cov txheej txheej huv (vim tias cov rauv taws), tsis tau tus nqi ntawm stripping yog ntau.
Kev muaj kuab paug ib puag ncig: tshuaj stripping tsim cov khoom pov tseg loj uas muaj cov hlau hnyav, cov teeb meem organic, thiab muaj zog acids / alkalis. Lub cev stripping ua cov txheej txheej-muaj cov plua plav (uas yuav muaj cov hlau hnyav thiab cov teeb meem). Cov no yuav tsum muaj kev phom sij tsis zoo los tiv thaiv kev ua qias tuaj tseem ceeb theem qub.
Cov khoom pov tseg: Cov txheej txheem stripping nws tus kheej noj lub zog thiab khoom siv, thiab qhov tshwm sim pov tseg yog ib qho tsis sib xws, uas yog qhov tsis sib xws nrog cov qauv ntawm kev lag luam ncig.
5.Qhov twg yog cov ntsiab lus tseem ceeb kom mloog thaum rov ua dua cov khib nyiab xim?
Sorting thiab collection: txheeb los ntawm hom substrate (piv txwv li, galvanized, galvanized, galvanized) lossis qib steel tau pom zoo kom pab txhawb cov hlau zeb batching.
Kev tawm tsam kev tshem tawm: thaum tsoo txheej tsis tsim nyog, loj uas tsis yog xim hlau accessories (piv txwv li cov hlua yas, ntoo, thiab cov av yas) yuav tsum tau muab tshem tawm. Cov impurities no tuaj yeem cuam tshuam cov txheej txheem steelmaking thiab molten hlau zoo.
Kev cog lus thiab ua kom tawg: rau kev yooj yim ntawm kev thauj mus los thiab txhim kho cov cua sov chaw tsim khoom, seem xim-txheej coils feem ntau yog ua kom sib xyaw thiab ua kom tawg rau hauv cov block.
Xaiv lub npe nrov tshaj tawm Channel: kom ntseeg tau tias cov qauv hloov kho tsim nyog los yog ncaj qha rau nws nkag mus rau cov kuab paug smelting thiab tsis txhob muaj cov kuab paug smelting thiab tsis txhob muaj kuab paug ib puag ncig los ntawm pov tseg.
Kev ceev faj kev nyab xeeb (thaum txiav cov khoom siv hnub nyoog (piv txwv li cov hmoov av muaj zog (piv txwv li cov hlau hnyav, seem uas muaj kev phom sij, thiab lwm yam). Cov neeg ua haujlwm yuav tsum hnav cov qhov ntswg tiv thaiv thiab cov tsom iav.
