Kub Rolled Steel Chev
Kub-dov coils yog ua los ntawm cov slabs (feem ntau yog nruam nruam daim hlau) ua raw khoom.Tom qab cua sov, lawv tau ua rau hauv sawb hlau los ntawm cov ntxhib dov zeb thiab lub tshuab tiav.Qhov kub steel sawb los ntawm qhov kawg dov zeb ntawm kev ua tiav dov yog txias rau qhov kub thiab txias los ntawm laminar ntws, thiab tom qab ntawd coiled rau hauv cov hlau sawb kauj los ntawm lub coiler, thiab txias steel strip coil.
Cold-dov coil (annealed): Kub-dov coil yog tau los ntawm pickling, txias dov, tswb annealing, flattening thiab (tiav).
Ntawd yog, qhov sib txawv loj tshaj plaws ntawm kub dov kauj thiab txias dov kauj yog cov txheej txheem kho cua sov.(Cov txheej txheem Annealing)
Piv nrog kub dov coils, txias dov coils muaj qhov ci ntsa iab thiab ntau dua tiav, tab sis lawv yuav ua rau muaj kev ntxhov siab ntau dua, thiab feem ntau annealed tom qab txias dov.
Kub dov steel sawb: Kub-dov hlau sawb, tseem hu ua kub dov steel sawb, feem ntau hu ua kub phaj.Kub-dov steel sawb nrog qhov dav ntawm tsawg dua lossis sib npaug ntawm 600mm, steel phaj nrog tuab ntawm 0.35-200mm thiab steel strip nrog thickness ntawm 1.2-25mm.Lub zog ntawm cov phaj kub-kuav los tiag yog qhov tsawg, thiab qhov zoo ntawm qhov chaw tsis zoo (nrog oxidation #92; qis tiav), tab sis nws muaj cov yas zoo.Feem ntau, nws yog nruab nrab thiab hnyav phaj, txias dov phaj, siab zog, siab hardness, siab nto tiav, thiab feem ntau nyias phaj.Raws li ib tug stamping board.
Cold-rolled strip steel: txias-dov strip steel thiab cov ntawv hlau feem ntau muaj cov tuab ntawm 0.1-3mm thiab dav ntawm 100-2000mm;lawv txhua tus siv cov kub dov los yog steel phaj ua raw khoom, thiab dov mus rau hauv cov khoom los ntawm txias dov mills ntawm chav tsev kub.
Cov phaj txias-kuav los tiag steel phaj muaj qee qhov kev ua haujlwm hardening thiab tsis tshua muaj zog, tab sis tuaj yeem ua tiav cov txiaj ntsig zoo dua.Nws yog siv rau cov ntawv txias-tsim caij nplooj ntoos hlav thiab lwm qhov chaw.
Feem ntau, seb daim ntawv yog kub-dov los yog txias-dov yog hais txog cov tuab thiab cov ntsiab lus carbon.
Lub phaj xav tau yuav tsum muaj cov hlau tuab dua kom kub dov.Txias dov yuav tsim cov yas loj deformation, uas yuav ua rau muaj kev ntxhov siab nyob hauv cov khoom thiab ua rau muaj kev ntxhov siab tawg.Nyob rau tib lub sijhawm, daim hlau uas muaj cov ntsiab lus siab dua cov pa roj carbon monoxide tsis haum rau qhov txias dov, thiab cov khoom siv nrog cov ntsiab lus carbon siab muaj lub zog siab, uas tsis yog qhov zoo rau cov yas deformation loj.
