Cold Rolled Duplex Strip ASTM A240 201 304 316 409 Chitsulo Chopanda chitsulo

The pamwamba processing wa coils zosapanga dzimbiri zitsulo ndi NO.1, 2B, No. 4, HL, No. 6, No. 8, BA, TR molimba, Rerolled yowala 2H, kupukuta owala ndi zina pamwamba akumaliza, etc.

NO.1: No. 1 pamwamba imatanthawuza pamwamba omwe amapezeka ndi chithandizo cha kutentha ndi pickling pambuyo pa kupukuta kotentha kwa chingwe chosapanga dzimbiri.Ndiko kuchotsa sikelo yakuda ya okusayidi yomwe imapangidwa pakugudubuzika kotentha ndi chithandizo cha kutentha pogwiritsa ntchito pickling kapena njira zina zochizira.Ichi ndi Nambala 1 processing pamwamba.No.1 pamwamba ndi silvery woyera ndi matt.Amagwiritsidwa ntchito makamaka m'mafakitale osamva kutentha komanso kuzizira omwe safuna gloss pamwamba, monga mafakitale a mowa, makampani opanga mankhwala ndi zotengera zazikulu.

2B: Pamwamba pa 2B ndi yosiyana ndi 2D pamwamba kuti ndi yosalala ndi yosalala wodzigudubuza, kotero ndi yowala kuposa 2D pamwamba.Pamwamba pa roughness Ra mtengo woyezedwa ndi chida ndi 0.1 ~ 0.5μm, womwe ndi mtundu wofala kwambiri wokonza.Mtundu woterewu wazitsulo zosapanga dzimbiri ndizomwe zimagwiritsidwa ntchito kwambiri, zomwe zimagwiritsidwa ntchito nthawi zambiri, zomwe zimagwiritsidwa ntchito kwambiri mu mankhwala, mapepala, mafuta, mankhwala ndi mafakitale ena, komanso zingagwiritsidwe ntchito ngati khoma lotchinga nyumba.

TR Hard Finish: Chitsulo chosapanga dzimbiri cha TR chimatchedwanso chitsulo cholimba.Makalasi ake oyimira zitsulo ndi 304 ndi 301, amagwiritsidwa ntchito pazinthu zomwe zimafuna mphamvu zambiri komanso kuuma, monga magalimoto a njanji, malamba oyendetsa, akasupe ndi ma gaskets.Mfundo yake ndikugwiritsa ntchito mawonekedwe owumitsa a austenitic chitsulo chosapanga dzimbiri kuti awonjezere mphamvu ndi kuuma kwa mbale yachitsulo ndi njira zozizira zogwirira ntchito monga kugudubuza.Zinthu zolimba zimagwiritsa ntchito maperesenti angapo mpaka makumi angapo peresenti ya kugudubuzika pang'ono m'malo mwa kutsetsereka pang'ono kwa 2B base surface, ndipo palibe annealing imachitika mutagubuduza.Chifukwa chake, gawo lolimba la TR lazinthu zolimba ndizomwe zimakulungidwa pambuyo pozizira kwambiri.

Kubwereza Bright 2H: Pambuyo pakugudubuza.zitsulo zosapanga dzimbiri zidzasinthidwa kukhala annealing owala.Mzerewu ukhoza kuziziritsidwa mwachangu ndi mzere wopitilira wa annealing.Liwiro loyenda la chingwe chachitsulo chosapanga dzimbiri pamzerewu ndi pafupifupi 60m ~ 80m/min.Pambuyo pa sitepe iyi, kumalizidwa kwapamwamba kudzakhala 2H yowoneka bwino.

No.4: Pamwamba pa No. 4 ndi mawonekedwe opukutidwa bwino omwe amawala kwambiri kuposa pamwamba pa No. m'munsi ndi kupukuta ndi lamba abrasive ndi kukula kwa njere 150-180 # Pamakina pamwamba.Kukula kwapamtunda Ra mtengo woyezedwa ndi chida ndi 0.2 ~ 1.5μm.NO.4 pamwamba imagwiritsidwa ntchito kwambiri m'malesitilanti ndi zida zakukhitchini, zida zamankhwala, zokongoletsera zomangamanga, zotengera, ndi zina.

HL: HL pamwamba nthawi zambiri amatchedwa hairline finish.Muyezo wa JIS waku Japan umanena kuti lamba wonyezimira wa 150-240# umagwiritsidwa ntchito kupukuta tsitsi losalekeza ngati lamba lomwe limapezeka.Muyeso waku China wa GB3280, malamulowo ndi osamveka bwino.Kumaliza kwa HL kumagwiritsidwa ntchito kwambiri popanga zokongoletsera monga ma elevator, ma escalator, ndi ma facade.

No.6: Pamwamba pa No.Pamwambapa pali zonyezimira zabwino zachitsulo komanso zofewa.Chiwonetserocho ndi chofooka ndipo sichiwonetsera chithunzicho.Chifukwa cha malo abwinowa, ndi abwino kwambiri popanga makoma a nsalu zotchinga ndikumanga zokongoletsera zam'mphepete, komanso amagwiritsidwa ntchito kwambiri ngati ziwiya zakukhitchini.

BA: BA ndi malo omwe amapezeka ndi chithandizo cha kutentha kowala pambuyo pozizira.Kuchiza kutentha kowala ndikumangirira pansi pamlengalenga woteteza womwe umatsimikizira kuti pamwamba sikhala ndi okosijeni kuti asungire gloss ya pamwamba-yozizira, ndiyeno gwiritsani ntchito mpukutu wosalala bwino kwambiri kuti muwongolere kuwala kuti muwoneke bwino pamwamba.Pamwambapa pali pafupi ndi galasi lomaliza, ndipo roughness pamwamba Ra mtengo woyezedwa ndi chida ndi 0.05-0.1μm.BA pamwamba imakhala ndi ntchito zambiri ndipo imatha kugwiritsidwa ntchito ngati ziwiya zakukhitchini, zida zapakhomo, zida zamankhwala, zida zamagalimoto ndi zokongoletsera.

No.8: No.8 ndi galasi lopangidwa ndi galasi lokhala ndi mawonekedwe apamwamba kwambiri opanda njere za abrasive.Makampani opanga zitsulo zosapanga dzimbiri amatchanso ngati mbale za 8K.Nthawi zambiri, zida za BA zimagwiritsidwa ntchito ngati zida zopangira galasi kumalizitsa pokhapokha popera ndi kupukuta.Pambuyo pa galasi lomaliza, pamwamba pake ndi zojambulajambula, choncho amagwiritsidwa ntchito kwambiri pomanga zokongoletsera pakhomo ndi kukongoletsa mkati.
