Qhov txawv ntawm kub dov steel sawb thiab txias dov steel sawb

(1) txias dov steel phaj vim muaj qee qhov kev ua haujlwm hardening, toughness yog tsawg, tab sis tuaj yeem ua tau zoo dua flexural zog piv, siv rau lub caij nplooj ntoos hlav txias thiab lwm yam.

(2) Cov phaj txias uas siv cov khaub thuas dov nto tsis muaj oxidized ntawm daim tawv nqaij, zoo zoo. Kub dov steel phaj siv kub dov ua nto oxide daim tawv nqaij, phaj thickness muaj nyob rau hauv qhov sib txawv.

(3) kub dov steel phaj toughness thiab nto flatness tsis zoo, tus nqi qis dua, thaum lub phaj txias dov stretching zoo, toughness, tab sis kim dua.

(4) dov yog muab faib ua txias dov thiab kub dov steel phaj, nrog rau cov recrystallization kub raws li qhov sib txawv.

(5) Txias dov: txias dov feem ntau yog siv rau hauv kev tsim cov sawb, nws dov ceev yog siab dua. Kub dov steel phaj: qhov kub ntawm kub dov yog zoo ib yam li forging.

(6) Qhov saum npoo ntawm kub dov steel phaj yam tsis muaj plating ua xim av xim av, qhov chaw ntawm cov phaj txias txias tsis muaj plating yog grey, thiab tom qab plating, nws tuaj yeem txawv ntawm qhov smoothness ntawm qhov chaw, uas siab tshaj qhov kub. dov steel phaj.

kub dov steel sawb

txias dov steel stripDefinition ntawm kub dov steel sawb

Kub-dov sawb dav tsawg dua los yog sib npaug ntawm 600mm, thickness ntawm 0.35-200mm steel phaj thiab thickness ntawm 1.2-25mm steel sawb.

Kub Rolled Sawb Market Positioning and Development Direction

Kub dov sawb hlau yog ib qho ntawm cov khoom tseem ceeb ntawm cov khoom siv hlau, dav siv hauv kev lag luam, kev ua liaj ua teb, kev thauj mus los thiab kev tsim kho, thiab tib lub sijhawm ua cov yeeb nkab txias, welded yeeb nkab, txias tsim steel thiab lwm yam khoom siv raw rau kev tsim khoom ntawm nws cov khoom. tso zis nyob rau hauv Tuam Tshoj lub xyoo tso zis ntawm steel nyob rau hauv tag nrho cov nyiaj ntawm ib tug loj feem ntawm lub tseem ceeb luag hauj lwm nyob rau hauv zus tau tej cov dov steel.

Nyob rau hauv industrially tsim lub teb chaws, kub dov phaj thiab sawb hlau accounted txog li 80% ntawm tag nrho cov zis ntawm phaj thiab sawb hlau, accounting rau ntau tshaj 50% ntawm tag nrho cov steel ntau lawm, thiab nyob rau hauv lub thoob ntiaj teb kev lag luam kev sib tw nyob rau hauv txoj hauj lwm.

Hauv Suav teb, cov khoom lag luam kub-kuav los tiag strip steel, qis qis ntawm cov thickness ntawm 1.8mm, tab sis qhov tseeb, tsawg heev manufacturers tam sim no tsim kub dov sawb hlau nrog ib tug tuab ntawm tsawg tshaj li 2.0 hli, txawm tias lub nqaim sawb. , lub thickness ntawm cov khoom yog feem ntau ntau dua 2.5 hli.

Yog li ntawd, ib feem tseem ceeb ntawm kev cia siab tias qhov tuab ntawm tsawg dua 2 hli sawb raws li cov neeg siv khoom siv raw, yuav tsum tau siv cov hlua khi txias.

Txias Rolled Sawb

Cold rolled steel strip: hlau nyob rau hauv lub recrystallization kub hauv qab lub dov deformation yog hu ua txias dov, feem ntau yog hais txog lub strip tsis rhuab thiab nyob rau hauv chav tsev kub ncaj dov txheej txheem. Cold dov strip tej zaum yuav kub rau qhov kov, tab sis nws tseem hu ua txias dov.

Cold dov ntau lawm tuaj yeem muab ntau qhov kev ua tau zoo thiab kev ua tau zoo ntawm steel phaj thiab sawb, nws qhov tseem ceeb tshaj plaws yog qhov ua haujlwm qis, piv nrog cov kub dov ntau lawm, nws muaj qhov zoo hauv qab no:

(1) Cov khoom siv txias txias yog qhov tseeb ntawm qhov loj me thiab cov tuab tuab, thiab qhov sib txawv ntawm cov sawb tuab feem ntau tsis ntau tshaj 0.01-0.03mm lossis tsawg dua, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev ua haujlwm siab.

(2) Cov strips nyias nyias uas tsis tuaj yeem tsim los ntawm kub dov tuaj yeem tau txais (qhov thinnest tuaj yeem ncav cuag 0.001mm lossis tsawg dua).

(3) Qhov zoo ntawm cov khoom siv txias txias yog qhov zoo dua, tsis muaj qhov kub dov strip feem ntau tshwm pitting, nias rau hauv cov hlau oxide thiab lwm yam tsis xws luag, thiab tuaj yeem tsim raws li tus neeg siv cov kev xav tau ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov sawb (glossy. nto los yog pitted nto, thiab lwm yam), txhawm rau pab txhawb kev ua cov txheej txheem tom ntej.

(4) Cold rolled strip steel muaj cov khoom siv zoo heev thiab cov txheej txheem ua haujlwm (xws li lub zog siab dua, qis qis qis, kev ua haujlwm zoo sib sib zog nqus, thiab lwm yam).

(5) Kev kub ceev dov thiab puv tas li dov tuaj yeem ua tiav, nrog cov khoom lag luam siab.

Cold Rolled Sawb Steel Classification

Cold rolled strip steel yog muab faib ua ob hom: dub thiab ci.

(1) dub annealed sawb: txias dov strip ncaj qha rhuab mus rau lub annealing kub, xim nto vim kub kub raug rau huab cua dub. Lub cev muaj zog ua mos, feem ntau yog siv rau steel sawb thiab txuas ntxiv siab, stamping, deformation ntawm kev sib sib zog nqus loj dua.

(2) ci ntsa iab annealed strip: thiab dub annealed qhov loj tshaj qhov sib txawv yog tias cov cua sov tsis nyob rau hauv kev sib cuag nrog huab cua, nrog nitrogen thiab lwm yam inert gases muaj kev tiv thaiv, lub nto xim kom tswj thiab txias dov strip, ntxiv rau cov dub annealed. kev siv kuj yog siv rau saum npoo ntawm npib tsib xee plating thiab lwm yam kev kho deg, zoo nkauj thiab dav.

Bright strip steel thiab dub fading sawb steel sib txawv: txhua yam khoom yuav luag tib yam, ci sawb hlau yog nyob rau hauv cov xim dub fading sawb hlau los ntawm ntau tshaj ib kauj ruam ntawm kev kho kom kaj.

Siv: dub fading sawb hlau feem ntau yog ua rau hauv cov khoom kawg ua ntej zoo ua qee qhov kev kho kom zoo nkauj, ci sawb hlau tuaj yeem ncaj qha mus rau hauv cov khoom kawg.

Txias dov steel ntau lawm txheej txheem cej luam

Txias dov sawb ntau lawm tshuab yog lub cim tseem ceeb ntawm theem ntawm kev loj hlob ntawm kev lag luam steel. Nyias steel phaj rau tsheb, tshuab ua liaj ua teb, tshuaj lom neeg kev lag luam, cov kaus poom zaub mov, kev tsim kho, cov khoom siv hluav taws xob thiab lwm yam kev lag luam, tab sis kuj muaj kev sib raug zoo nrog lub neej txhua hnub, xws li tsev neeg tub yees, tshuab ntxhua khaub ncaws, TV thiab lwm yam kev xav tau ntawm nyias steel phaj. . Yog li, nyob rau hauv ib co industrially tsim lub teb chaws, nyias steel phaj accounted rau cov feem ntawm cov hlau nce xyoo los ntawm lub xyoo, nyob rau hauv lub nyias phaj, sawb hlau, txias dov khoom account rau ib tug loj feem.
