1. Kev taw qhia txog cov ntawv txias txias txias yog cov khoom tau los ntawm cov ntawv kub dov los ntawm kev ua haujlwm txias.
Vim muaj ntau qhov txias dov, qhov zoo ntawm qhov chaw zoo dua li ntawm cov ntawv kub dov, thiab cov khoom siv zoo tuaj yeem tau txais tom qab kev kho cua sov.
1. Kev faib tawm ntawm kev siv cov ntawv zoo tib yam txias-kuav los tiag Raws li cov kev xav tau sib txawv ntawm cov tuam txhab, cov nplooj ntawv txias-kuav los tiag feem ntau yog muab faib ua: cov ntawv txias-kuav los tiag, stamping-qib txias-dov los xij, sib sib zog nqus-kos duab, ntxiv-dov- daim duab thiab ultra-dav duab txias-kuav los tiag cov ntawv, feem ntau xa hauv cov ntawv coils thiab cov ntawv tiaj tus, cov tuab yog qhia hauv millimeters, qhov dav feem ntau yog 1000mm thiab 1250mm, thiab qhov ntev yog feem ntau 2000mm thiab 2500mm.
2. Cov qib zoo ntawm cov ntawv txias txias yog: Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC 0DC, thiab lwm yam .;ST12: qhia cov qib steel ntau tshaj plaws, uas yog qhov pib zoo ib yam li Q195, SPCC, DC01 qib;ST13/14: qhia txog qib stamping steel qib, uas yog qhov pib zoo ib yam li qib 08AL, SPCD, DC03/04;ST15/16: qhia tias Nws yog qib stamping steel, yeej zoo ib yam li 08AL, SPCE, SPCEN, DC05/06 qib.
3. Qhov loj sawv cev txoj kev ntawm qib ntawm cov ntawv txias txias, xws li ST12 ua los ntawm Anshan Hlau thiab Hlau, 1 * 1250 * 2500 / C, qhia raws li: qib ST12 cov ntawv txias txias, thickness 1mm, dav 1250mm, ntev 2500mm los yog C coil.Cov tsos yog zoo ntim hauv cov hlau dawb, thiab cov khoom siv kho tshuab yog cov qib siab tshaj plaws thiab qib steel, uas tsuas yog siv tau rau kev khoov thiab sib sau, tsis yog rau stamping.Siv rau cov neeg kho tshuab tom, xws li lub tub yees plhaub, lub tsheb roj tso tsheb hlau luam, thiab lwm yam. Cov khoom siv saum toj no ST13 yog siv rau hauv kev lag luam uas yuav tsum tau muaj kev sib sib zog nqus nqus, xws li tsheb tsim, roj tso tsheb hlau luam rau lub cav diesel, thiab lwm yam. Cov hom tshwj xeeb yuav tsum tau siv yog nyob ntawm qhov sib sib zog nqus kev xav tau.
Qhov sib txawv ntawm ST12 thiab SPCC: Cov khoom siv kho tshuab ntawm ob yam khoom yuav luag tib yam, tab sis txoj kev annealing txawv.Cov khoom tensile ntawm ST12 cov ntaub ntawv muaj zog dua SPCC.Japanese JIS tus qauv cov khoom siv lub ntsiab lus SPCC-S txhais tau tias steel (Steel), P txhais tau tias phaj (Plate), C txhais tau tias txias (Cold), C txhais tau tias kev lag luam (Kev lag luam), uas yog Japanese JIS tus qauv.Txhawm rau kom muaj zog tensile, ntxiv T thaum kawg ntawm qib: SPCT.SPCD - sawv cev rau cov ntawv txias-kuav los tiag carbon steel ntawv thiab sawb rau stamping, uas yog sib npaug rau Tuam Tshoj 08AL (13237) zoo carbon structural steel.SPCE - sawv cev rau cov ntawv txias dov carbon steel thiab sawb rau kev sib sib zog nqus kos duab, uas yog sib npaug rau Tuam Tshoj 08AL (5213) sib sib zog nqus nqus hlau.Txhawm rau kom tsis txhob ncua sijhawm, ntxiv N thaum kawg ntawm qib kom ua SPCEN.Cold-rolled carbon steel ntawv thiab strip quenching thiab tempering code: annealing xeev yog A, txheem quenching thiab tempering yog S, 1/8 hardness yog 8, 1/4 hardness yog 4, 1/2 hardness yog 2, thiab tag nrho hardness yog 1. Cov txheej txheem deg: npub tiav dov yog D, ci ntsa iab dov yog B. Piv txwv li, SPCC-SD sawv cev rau lub hom phiaj ntawm cov ntawv txias-kuav los tiag nrog cov txheej txheem quenching thiab tempering thiab matte tiav dov.Lwm qhov piv txwv yog SPCCT-SB, uas txhais tau hais tias tus txheej txheem quenching thiab tempering, ci ua, thiab txias-dov cov ntawv carbon uas yuav tsum tau guaranteed txhua yam khoom.Lwm qhov piv txwv yog SPCC-1D, uas sawv cev rau ib qho nyuaj matte tiav-dov txias-kuav los tiag carbon steel ntawv.
Txoj kev sawv cev ntawm qib steel rau cov qauv siv tshuab yog: S + carbon cov ntsiab lus + tsab ntawv code (C, CK), uas cov ntsiab lus carbon yog sawv cev los ntawm tus nqi nruab nrab * 100, tsab ntawv C sawv cev rau carbon, thiab tsab ntawv K sawv cev rau cov hlau. rau carburizing.Xws li carbon knot coil S20C, nws cov ntsiab lus carbon yog 0.18-0.23%.Lub ntsiab lus ntawm Suav GB txheem cov ntaub ntawv yog muab faib ua: Q195, Q215, Q235, Q255, Q275 thiab hais txog.Q sawv cev rau thawj tsab ntawv ntawm Suav pinyin ntawm lo lus "Qu" rau lub ntsiab lus ntawm cov hlau, thiab 195, 215, thiab lwm yam. sawv cev rau tus nqi ntawm qhov taw tes tawm los.Nyob rau hauv cov nqe lus ntawm cov tshuaj muaj pes tsawg leeg, qis carbon steel qib: Q195, Q215, Q235, Q255, Q275 Qhov siab dua cov ntsiab lus carbon thiab manganese cov ntsiab lus, qhov ruaj khov nws plasticity yog.
2. Kev taw qhia ntawm cov ntawv kub-dip galvanized steel ntawv (nyiaj dawb) yog tsim los ntawm cov txheej txheem kub-dip galvanizing nrog kub-dip steel sawb los yog txias-kuav los tiag steel sawb raws li lub substrate, uas tuaj yeem tiv thaiv qhov saum npoo ntawm nyias steel phaj thiab hlau. strip los ntawm corroding thiab rusting.Cov ntawv kub-dip galvanized yog muab rau hauv cov ntawv tiaj tiaj tiaj tom qab hla hla;Kub-dip galvanized coils yog nkag rau hauv coils tom qab coiling.Vim yog siv cov substrates sib txawv, cov nplooj ntawv kub-dip galvanized steel tuaj yeem muab faib ua cov ntawv kub dov galvanized thiab coils thiab txias-dip kub-dip galvanized nplooj ntawv thiab coils, uas yog siv hauv kev tsim kho, khoom siv hauv tsev, tsheb, ntim, kev thauj mus los thiab kev lag luam hauv tsev.Tshwj xeeb tshaj yog nyob rau hauv steel qauv tsim, tsheb tsim, steel qhov rais manufacturing thiab lwm yam lag luam.
1. Cov yam ntxwv ntawm kub-dip galvanized steel ntawv yog muaj zog corrosion kuj, zoo nto zoo, haum rau kev sib sib zog nqus ua, yig thiab siv tau, thiab lwm yam.
2. Kev faib tawm thiab cov cim ntawm cov ntawv kub-dip galvanized steel ntawv tau muab faib ua: lub hom phiaj dav dav (PT), kev sib koom ua ke (JY), kos duab sib sib zog nqus (SC), super sib sib zog nqus kev laus laus (CS), qauv (JG) raws li cov kev ua tau zoo;Qhov hnyav tau muab faib ua: zinc txheej ntshiab yog muab faib ua: 100/100 (zinc txheej hnyav yog tsawg dua 100g / m2), 120/120, 200/200, 275/275, 350/350, 450/450, 600/600 ;zinc-hlau alloy nto Muab faib ua: 90/90 (qhov hnyav ntawm zinc-hlau alloy txheej yog tsawg dua 90g / m2), 100/100, 120/120, 180/180;Raws li cov qauv saum npoo: ib txwm spangle Z, me spangle X, du spangle GZ, Zinc-hlau alloy XT;Raws li qhov zoo ntawm qhov chaw, nws muab faib ua: I pawg (I), II pawg (II);Raws li qhov tseeb qhov tseeb, nws tau muab faib ua: siab tshaj precision A, zoo tib yam precision B;Raws li kev kho saum npoo, nws tau muab faib ua: chromic acid passivation L, txheej roj Y, chromic acid passivation ntxiv rau roj LY.
Baosteel kub-dip galvanized steel ntawv: Baosteel Phase II Kub-dip Galvanizing Baosteel Theem II kub-dip galvanizing yog tsim los ntawm kev nruam dipping galvanizing ntawm txias tandem los yog kub tandem dov hlau nyob rau hauv 2030 chav tsev rau lub hom phiaj los yog cov qauv siv.
Lub Scope ntawm kev muab khoom ntawm theem ob ntawm kub-dip galvanizing: thickness (0.3-0.3) dav (800-1830) ntev (phaj 1000-6000, coil puab txoj kab uas hla 610) unit mm.
Qhov thib ob-theem kub-dip galvanizing yog muab faib raws li cov qauv saum npoo: Z txhais tau tias ib txwm spangle, N txhais tau tias xoom spangle, X txhais tau tias me me spangle, thiab G txhais tau tias du spangle.
Qhov thib ob-theem kub-dip galvanizing yog muab faib raws li kev kho deg: L txhais tau tias chromic acid passivation, Y txhais tau tias oiling, LY txhais tau tias chromic acid passivation + oiling yog tsuas yog txo los yog tsis txhob xeb dawb thaum thauj los yog cia.
