1. Kev taw qhia luv luv ntawm cov phaj txias-kuav los tiag
Nws yog ib qho khoom tau los ntawm kev nias txias ntawm cov ntawv kub dov. Vim muaj ntau qhov txias dov, nws qhov zoo ntawm qhov chaw zoo dua li cov ntawv kub dov, thiab tom qab kev kho cua sov, cov khoom siv zoo tuaj yeem tau txais.
1. Kev faib tawm ntawm kev siv cov phaj txias-kuav los tiag
Raws li cov kev xav tau sib txawv ntawm cov tuam txhab tsim khoom, cov ntawv txias txias feem ntau muab faib ua:
Feem ntau siv cov ntawv txias-kuav los tiag, stamping-qib txias-kuav los tiag daim ntawv, sib sib zog nqus-kos duab, ntxiv-sib sib zog nqus-kos duab thiab ultra-dav duab-qib txias-kuav los tiag ntawv,
Feem ntau xa hauv coils thiab cov ntawv tiaj tus, lub thickness yog qhia hauv millimeters,
Qhov dav yog feem ntau: 1000mm thiab 1250mm, thiab qhov ntev yog feem ntau 2000mm thiab 2500mm.
2. Qib zoo tib yam txias dov phaj
Cov qhab-nees feem ntau yog:
Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06, thiab lwm yam.
Qauv: ST12
Qhia tawm raws li qib steel feem ntau, cov khoom siv yog tib yam li Q195, SPCC, thiab DC01 qib;
TSW 13/14:
Cov qib steel tau hais tias qib stamping yog qhov tseem ceeb ntawm cov khoom ntawm 08AL, SPCD, DC03/04 qib;
Qauv: ST15/16
Cov qib steel tau qhia tias qib stamping yog qhov tseem ceeb ntawm cov khoom ntawm 08AL, SPCE, SPCEN, DC05/06 qib.
3. Cov txheej txheem ntawm kev nthuav qhia qib thiab qhov loj ntawm cov ntawv txias txias-kuav los tiag
Piv txwv li, ST12 ua los ntawm Taishan Industrial Development Group Hlau thiab hlau Co., Ltd., 1 * 1250 * 2500 / C, qhia raws li: qib ST12 zoo tib yam txias phaj, thickness yog 1 hli, dav yog 1250 hli, ntev yog 2500 hli los yog C coil .
Lub ntsej muag yog ntim nrog cov tawv nqaij dawb hlau, thiab cov khoom siv kho tshuab yog cov qib steel ntau tshaj plaws thiab yooj yim, uas tsuas yog siv rau kev khoov thiab sib sau, tsis yog rau stamping. Siv rau mechanical tom,
Piv txwv li, lub plhaub ntawm lub tub yees, roj tank ntawm lub tsheb, thiab lwm yam.
Cov khoom siv saum toj no ST13 yog siv rau hauv kev lag luam uas xav tau kev kos duab sib sib zog nqus, xws li kev tsim tsheb, roj tso tsheb hlau luam rau cov cav tov diesel, thiab lwm yam, uas yuav siv tau yog nyob ntawm qhov xav tau sib sib zog nqus.
Qhov sib txawv ntawm ST12 thiab SPCC: Cov khoom siv kho tshuab ntawm ob yam khoom yuav luag tib yam, tab sis txoj kev xa rov qab txawv. Cov khoom tensile ntawm ST12 cov khoom muaj zog dua li ntawm SPCC.
Japanese JIS 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 hais tias coj mus muag (Commercial), uas yog Japanese JIS tus qauv.
Yog tias koj xav tau kom lub zog tensile, ntxiv T thaum kawg ntawm qib, uas yog: SPCCT.
SPCD - qhia cov ntawv txias-kuav los tiag carbon steel ntawv thiab sawb rau stamping, uas yog sib npaug rau Tuam Tshoj tus 08AL (13237) zoo carbon structural steel.
SPCE - Qhia cov ntawv txias-dov carbon steel thiab sawb rau kev sib sib zog nqus kos duab, uas yog sib npaug rau Tuam Tshoj tus 08AL (5213) sib sib zog nqus nqus hlau.
Yog tias yuav tsum tsis ua raws sijhawm, ntxiv N thaum kawg ntawm qib ua SPCEN.
Cold-rolled carbon steel ntawv thiab steel sawb quenching thiab tempering code: annealed xeev yog A, txheem quenching thiab tempering yog S, 1/8 hardness yog 8, 1/4 hardness yog 4, 1/2 hardness yog 2, tag nrho hardness yog 1. Nto ua code: D rau npub tag dov, B rau ci tiav dov.
Piv txwv li, SPCC-SD sawv cev rau tus qauv quenched thiab tempered, matte tiav dov dav dav-lub hom phiaj txias-kuav los tiag carbon ntawv.
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 txhais tau hais tias ib qho nyuaj matt tiav txias-kuav los tiag carbon steel ntawv.
Txoj kev qhia ntawm cov qib steel rau cov khoom siv tshuab yog: S + carbon cov ntsiab lus + tsab ntawv code (C, CK), qhov twg 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 carburizing steel. . Piv txwv li, carbon knot coil S20C muaj cov ntsiab lus carbon ntawm 0.18-0.23%.
Tuam Tshoj GB txheem khoom lub ntsiab lus
Hauv paus muab faib ua:
Q195, Q215, Q235, Q255, Q275, thiab lwm yam.
Q sawv cev rau thawj tsab ntawv ntawm Suav pinyin ntawm lo lus "Qu" ntawm 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 tshuaj muaj pes tsawg leeg, qis carbon steel qib:
Qhov loj dua qib ntawm Q195, Q215, Q235, Q255, thiab Q275, qhov siab dua cov ntsiab lus carbon thiab manganese cov ntsiab lus, thiab ruaj khov dua cov yas.
2. Kev taw qhia luv luv ntawm kub-dip galvanized steel ntawv (nyiaj dawb)
Nws yog tsim los ntawm kub-kuav los tiag steel sawb los yog txias-kuav los tiag steel sawb raws li lub substrate los ntawm tas mus li kub-dip galvanizing txheej txheem, uas yuav tiv thaiv lub nto ntawm nyias steel phaj thiab steel sawb los ntawm corrosion thiab xeb.
Cov ntawv kub-dip galvanized yog muab los ua ib lub phaj tiaj tiaj los ntawm kev hla hla; lub kub-dip galvanized kauj yog muab raws li ib tug yob los ntawm coiling.
Vim yog siv cov substrates sib txawv, cov ntawv kub-dip galvanized steel ntawv tuaj yeem muab faib ua cov ntawv kub dov galvanized coils thiab txias dov kub-dip galvanized sheet coils, uas yog siv hauv kev tsim kho, khoom siv hauv tsev, tsheb, ntim, tsheb thauj mus los thiab kev lag luam hauv tsev. Tshwj xeeb tshaj yog steel qauv tsim, tsheb tsim, steel qhov rais manufacturing thiab lwm yam lag luam.
1. Cov yam ntxwv ntawm kub-dip galvanized steel ntawv
Muaj zog corrosion kuj, zoo nto zoo, zoo rau kev sib sib zog nqus ua, yig thiab siv tau, thiab lwm yam.
2. Kev faib tawm thiab cov cim ntawm kub-dip galvanized steel ntawv
Raws li kev ua tau zoo, nws tau muab faib ua: lub hom phiaj dav dav (PT), kev sib cuam tshuam (JY), kos duab sib sib zog nqus (SC), super sib sib zog nqus kev laus (CS), thiab cov qauv (JG);
Raws li qhov hnyav ntawm zinc txheej: saum npoo ntawm zinc ntshiab yog muab faib ua: 100/100 (qhov hnyav ntawm zinc txheej yog tsawg dua 100g / m2),
120/120, 200/200, 275/275, 350/350, 450/450, 600/600;
