Qhov saum npoo ntawm lub phaj txias-kuav los tiag muaj ib qho gloss thiab zoo nkaus li du, zoo ib yam li lub khob steel ntau siv rau cov dej haus.2. Yog tias cov phaj kub kub tsis yog pickled, nws zoo ib yam li cov phaj hlau zoo tib yam ntawm ntau lub khw.Qhov chaw xeb yog xim liab, thiab qhov chaw tsis muaj xeb yog xim liab-dub (hlau oxide).

Qhov kev ua tau zoo ntawm cov ntawv txias dov thiab cov ntawv kub dov yog:

(1) siab dua, thickness sib txawv ntawm txias dov strip tsis ntau tshaj 0.01 ~ 0.03mm.

(2) Thinner me me, thinnest txias dov tuaj yeem yob 0.001mm steel sawb;Kub dov tam sim no mus txog qhov tsawg kawg nkaus thickness ntawm 0.78mm.

(3) Qhov zoo tshaj plaws nto, txias dov steel phaj tuaj yeem tsim daim iav nto;Qhov saum npoo ntawm kub - dov phaj muaj qhov tsis xws li hlau oxide thiab pitting.

(4) Cov ntawv txias-dov tuaj yeem hloov kho raws li cov neeg siv khoom xav tau ntawm nws cov khoom siv xws li lub zog tensile thiab cov txheej txheem cov khoom xws li cov khoom stamping.

Txias dov thiab kub dov yog ob qho sib txawv steel dov tshuab, raws li lub npe cuam tshuam, txias dov yog khi hlau ntawm chav tsev kub, qhov hardness ntawm cov hlau no loj.Kub dov yog thaum hlau khi ua ke ntawm qhov kub thiab txias.Kub dov ntawv muaj tsawg hardness, yooj yim ua thiab zoo ductility.Cov ntawv txias dov hardness yog siab, kev ua haujlwm yog qhov nyuaj, tab sis tsis yooj yim rau deformation, siab zog.Kub dov phaj lub zog yog qhov tsawg, qhov zoo ntawm qhov yuav luag (oxidation, tsis tshua muaj tiav), tab sis zoo plasticity, feem ntau nruab nrab tuab phaj, txias dov phaj: siab zog, siab hardness, siab nto tiav, feem ntau nyias phaj, tuaj yeem siv los ua ib qho stamping phaj.Kub dov steel phaj, mechanical zog yog nyob deb inferior rau txias ua, kuj inferior rau forging ua, tab sis muaj zoo toughness thiab ductility.Txias dov steel phaj vim muaj qee qhov kev ua haujlwm hardening, tsis tshua muaj zog, tab sis tuaj yeem ua tiav qhov zoo flexural piv, siv rau lub caij nplooj ntoos hlav txias thiab lwm yam, tib lub sijhawm vim tias qhov taw tes tawm los ze dua rau lub zog tensile, yog li kev siv phom sij tsis yog kev twv ua ntej, thaum lub nra hnyav tshaj qhov kev tso cai thauj khoom yog qhov ua rau muaj xwm txheej.Los ntawm kev txhais, steel ingot los yog billet yog qhov nyuaj rau deform thiab txheej txheem ntawm chav tsev kub.Nws yog feem ntau rhuab mus rau 1100 ~ 1250 ℃ rau dov.Cov txheej txheem dov no hu ua kub dov.Cov hlau feem ntau yog dov los ntawm kub dov.Txawm li cas los xij, vim tias cov hlau saum npoo yog ib qho yooj yim los tsim cov oxide ntawv ntawm qhov kub thiab txias, qhov saum npoo ntawm kub dov hlau yog ntxhib thiab qhov loj me hloov pauv, yog li cov hlau nrog du nto, qhov loj me thiab cov khoom siv kho kom zoo yuav tsum muaj, thiab kub. dov semi-tiav khoom los yog cov khoom tiav yog siv los ua raw khoom thiab tom qab ntawd ua los ntawm txoj kev txias dov.Rolling nyob rau hauv chav tsev kub yog feem ntau to taub raws li txias dov.Los ntawm qhov kev xav ntawm kev tshawb fawb hlau, tus ciam teb ntawm qhov txias dov thiab kub dov yuav tsum txawv ntawm recrystallization kub.Ntawd yog, qhov dov hauv qab qhov kub ntawm recrystallization yog txias dov, thiab dov saum toj no lub recrystallization kub yog kub dov.Lub recrystallization kub ntawm steel yog 450 ~ 600 ℃.Kub dov, raws li lub npe implies, dov qhov chaw ntawm qhov kub thiab txias, yog li lub deformation kuj yog me me, tuaj yeem ua tiav qhov loj deformation.Noj steel phaj dov ua piv txwv, lub thickness ntawm nruam casting billet yog hais txog 230mm, thiab tom qab ntxhib dov thiab tiav dov, qhov kawg thickness yog 1 ~ 20mm.Nyob rau tib lub sijhawm, vim tias qhov sib piv ntawm cov hlau phaj me me, qhov tseeb qhov tseeb yog qhov tsawg, nws tsis yooj yim rau pom qhov teeb meem zoo, feem ntau yog tswj cov yas.Lub microstructure thiab mechanical zog ntawm sawb hlau tuaj yeem tswj tau los ntawm kev tswj cov dov kub, dov kub thiab crimping kub.Txias dov, feem ntau tsis muaj txheej txheem cua sov ua ntej dov.Txawm li cas los xij, vim tias cov strip thickness me me, nws yog ib qho yooj yim los tshwm sim cov teeb meem.Ntxiv mus, tom qab txias dov yog cov khoom tiav lawm, yog li ntawd, txhawm rau tswj qhov tseeb qhov tseeb thiab qhov zoo ntawm cov sawb hlau, ntau txoj kev tedious heev yog siv.Txias dov ntau lawm kab yog ntev, ntau yam khoom siv, txheej txheem nyuaj.Nrog rau kev txhim kho ntawm cov neeg siv cov kev xav tau ntawm qhov tseeb qhov tseeb, cov duab thiab qhov zoo ntawm cov sawb hlau, muaj ntau cov qauv tswj, L1 thiab L2 systems thiab cov qauv tswj cov txheej txheem hauv txias dov zeb dua li kub dov zeb.Ntxiv mus, qhov kub thiab txias ntawm cov menyuam thiab sawb kuj yog ib qho tseem ceeb tswj kev ntsuas.Cov khoom siv txias txias thiab cov khoom kub dov cov ntawv kab, yog qhov sib txawv ntawm cov txheej txheem dhau los thiab cov txheej txheem tom ntej, cov khoom kub dov yog cov khoom siv raw khoom ntawm cov khoom siv txias txias, txias dov tom qab pickling kub dov steel coil tshuab siv cov menyuam zeb, dov, yog txias ua molding, feem ntau dov tuab kub dov phaj rau hauv nyias specifications txias dov phaj, Feem ntau xws li 3.0 hli kub dov phaj ntawm lub tshuab dov yuav ua tau 0.3-0.7 hli txias dov coil, lub ntsiab ntsiab yog siv lub hauv paus ntsiab lus ntawm extrusion. yuam deformation.
