Tuam Tshoj ncaj qha muag txias dov steel kauj DC01-DC06 siab zog steel yob
piav qhia
Cold dov kauj yog hais txog cov hlau sawb uas yog dov rau hauv ib lub thickness ncaj qha los ntawm cov menyuam ntawm chav tsev kub thiab dov rau hauv tag nrho cov kauj los ntawm lub coiler.Piv nrog kub dov coil, txias dov coil nto ci, siab dua tiav, tab sis yuav ua rau muaj kev ntxhov siab ntau dua, tom qab txias dov feem ntau xav tau kev kho mob annealing.
Kub dov steel kauj yog siv los ua raw khoom, tom qab acid pickling kom tshem tawm cov oxide scale, txias dov, dov rau hauv ib tug nyuaj coil.Lub zog, hardness, toughness thiab plasticity Performance index ntawm dov tawv yob yog txhim kho los ntawm txias ua hauj lwm hardening los ntawm tas mus li txias deformation., yog li qhov kev ua haujlwm stamping yuav tsis zoo, tsuas yog siv tau yooj yim deformation ntawm qhov chaw.Hard dov coils tuaj yeem siv los ua cov ntaub ntawv raw hauv cov nroj tsuag kub-dip galvanizing vim cov kab kub-dip galvanizing yog nruab nrog cov xov hlau deignition.Qhov hnyav ntawm dov tawv yob feem ntau yog 20-40 tons.Kub dov pickling rolls yog txuas ntxiv dov nyob rau hauv chav tsev kub.Sab hauv txoj kab uas hla yog 610mm.
Khoom nta
Vim tsis muaj annealing kev kho mob, siab hardness (HRB> 90), tsis zoo machinability, tsuas yog nqa tawm hauv qab 90 degrees ntawm yooj yim directional dabtsi yog khoov (perpendicular mus rau lub coiling kev taw qhia).
Txhawm rau muab nws yooj yim, txias dov yog ua tiav thiab dov los ntawm lub hauv paus ntawm kub dov kauj.Feem ntau hais lus, nws yog qhov kub dov - pickling - txias dov txheej txheem.
Cov ntawv txias dov yog ua los ntawm cov ntawv kub dov ntawm chav tsev kub.Txawm hais tias qhov kub ntawm cov phaj hlau yuav nce siab thaum ua, nws tseem hu ua txias dov.Vim tsis tu ncua txias deformation ntawm kub dov, txhua yam khoom tsis zoo thiab hardness yog siab dhau.Nws yuav tsum tau annealed los kho nws cov khoom siv kho tshuab, thiab cov uas tsis muaj annealed yog hu ua nyuaj dov coils.Hard dov coils feem ntau yog siv los ua cov khoom uas tsis tas yuav khoov lossis ncab.Coils nrog thickness tsawg dua 1.0 yog dov rau ob sab los yog plaub sab, muaj hmoo.
Daim ntawv thov
Cold rolled strip yog dav siv nyob rau hauv tsheb tsim, khoom siv hluav taws xob, dov Tshuag, aviation, precision instruments, kaus poom zaub mov, thiab lwm yam raws li txias dov phaj, qee zaum yuam kev sau ua txias dov phaj.Cov phaj txias yog kub dov sawb ntawm cov qauv carbon ntau, uas yog ntxiv txias dov rau hauv cov hlau phaj nrog thickness tsawg dua 4 hli.Vim yog qhov kub thiab txias dov, tsis muaj oxide nplai, yog li qhov zoo ntawm cov phaj txias yog qhov zoo, qhov tseeb qhov tseeb, ua ke nrog kev kho annealing, nws cov khoom siv thiab cov txheej txheem ua tau zoo dua li kub dov steel phaj, nyob rau hauv ntau qhov chaw, tshwj xeeb tshaj yog nyob rau hauv cov khoom. teb ntawm cov khoom siv hauv tsev tsim khoom, tau maj mam hloov kub dov steel phaj
