Hauv kev lag luam steel, cov phooj ywg feem ntau ntsib ntau yam no, thiab tseem muaj cov phooj ywg uas feem ntau tsis tuaj yeem qhia qhov txawv ntawm lawv:
Puas yog pickling cais ua txias dov lossis kub dov?
Puas yog txoj kev txias txias cais raws li txias dov lossis kub dov?
Puas nyuaj dov tib yam li txias dov?
Cov no yog cov tsim txom uas ntaus tus ntsuj plig hauv kev lag luam steel.Cov pawg tsis meej pem tuaj yeem yooj yim ua rau muaj kev pheej hmoo ntawm kev lag luam thiab kev tsis sib haum xeeb thiab kev thov.
Thaum txheeb xyuas ntau yam, thawj qhov uas yuav tsum tau qhia meej yog lub ntsiab lus ntawm cov khoom no.Cov npe no feem ntau yog xa mus rau qis carbon steel coils:
Pickling: feem ntau yog hais txog cov khoom uas kub-kuav los tiag steel coils undergo ib chav pickling kom tshem tawm oxide nplai.
Hard dov: feem ntau yog hais txog cov kub dov steel coil uas tau muab khaws cia thiab tom qab ntawd thinned los ntawm lub tshuab txias txias, tab sis tsis tau muab tshuaj txhuam.
Txias dov: feem ntau yog hais txog cov khoom ntawm cov dov tawv coils uas tau ua tiav los yog tsis tiav annealed.
Cold forming: feem ntau yog hais txog kub dov pickled nyias strip uas ua los ntawm ESP nruam casting thiab dov txheej txheem.
Qhov sib txawv ntawm cov txheej txheem ntau lawm
Yuav kom nkag siab txog plaub yam khoom no, koj yuav tsum nkag siab qhov sib txawv ntawm cov txheej txheem tsim khoom.
Pickling, nyuaj dov, thiab txias dov khoom yog cov khoom ntawm ntau theem hauv cov txheej txheem ntau lawm.Pickling yog cov khoom kub dov kom tshem tawm cov nplai, thiab cov dov tawv yog cov khoom ua ntej txias dov thiab annealing.
Txawm li cas los xij, kev sib sau txias yog ib yam khoom tshiab uas tsim los ntawm ESP cov kab ntau lawm (uas ua ke ob txoj kev nruam nruam thiab kub dov rau hauv ib chav).Cov txheej txheem no muaj ob yam ntxwv ntawm tus nqi qis thiab nyias kub dov thickness.Nws yog qhov kev xaiv zoo tshaj plaws ntawm ntau cov nroj tsuag hauv tsev.Lub ntsiab lus ntawm kev tawm tsam hauv xyoo tas los.
Kev ua tau zoo thiab qhov sib txawv ntawm kev siv
Piv nrog kub dov coils, lub hauv paus khoom ntawm pickled steel phaj tsis tau hloov thiab feem ntau yog siv nyob rau hauv lub sij hawm uas kub dov steel coils muaj ntau dua nto qhov yuav tsum tau.Hom hom yog SPHC, feem ntau hu ua "pickling C khoom" hauv kev lag luam.
Tus nqi ntawm cov yob yob tsis yog pheej yig, thiab cov formability thiab nto zoo tsis zoo, yog li nws yog feem ntau tsuas yog siv nyob rau hauv ib co kev lag luam nrog nyias specifications thiab tsis tshua muaj kev kawm yuav tsum tau, xws li kaus ribs los yog Hoobkas lockers.Cov qib feem ntau yog CDCM-SPCC, feem ntau hu ua "cov khoom siv txias C" hauv kev lag luam.
Tag nrho cov kev ua tau zoo ntawm txias dov steel coils yog qhov zoo heev, tab sis qhov tsis zoo yog tias nws yog qhov kim tshaj plaws (cov txheej txheem feem ntau, tus nqi siab tshaj).Cov qib sib txawv yog SPCC, feem ntau hu ua "cov khoom siv txias txias C" hauv kev lag luam.
Qhov kev ua tau zoo ntawm cov txheej txheem txias txias yog qhov zoo dua li ntawm cov tawv dov coils, tab sis tsis zoo li qhov txias dov steel coils (feem ntau cuam tshuam los ntawm kev kho cua sov muaj peev xwm thiab loj flattening ua hauj lwm hardening tom qab pickling).Qhov zoo tshaj plaws yog tias tus nqi qis heev, tshwj xeeb tshaj yog nyob rau hauv qhov tuab ntawm 1.0 ~ 2.0, uas yog siv los hloov cov khoom txias-kuav los tiag uas tsis tas yuav tsum muaj kev tsim siab (xws li dov, khoov, thiab lwm yam).
Thaum kawg, qee cov lus qhia:
1. Tuam Tshoj muaj ntau tshaj plaws ntawm ESP ntau lawm kab nyob rau hauv lub ntiaj teb no.Raws li lub hauv paus ntsiab lus hais tias qhov ntau nws ua, qhov kev loj hlob sai, cov txheej txheem no tuaj yeem txhim kho mus rau hauv ib qho loj loj uas tsis muaj nqi nyob rau ob peb xyoos.(Nrog rau semi-kawg dov thiab yob cam khwb cia nyias daim hlau).Tej zaum yuav muaj kev sib tw zoo hauv cov pa roj carbon tsawg yav tom ntej, tab sis thaum tus nqi ntawm cov khoom siv qis qis, cov khoom tsim hauv Suav teb yuav dhau los ua kev sib tw thoob ntiaj teb.
2. Cold-formed coils kuj yog high-zoo kub-dip galvanized substrates.Cov khoom qub tsis zoo tuaj yeem txhim kho nyob rau hauv cov txheej txheem annealing ntawm chav tsev kub-dip galvanizing, thiab cov khoom kub-dip galvanized rau cov duab sib sib zog nqus tuaj yeem tsim.Tsis tas li ntawd, nws cov nqi muaj qhov zoo ntawm dov tshaj hard-dov kub-dip substrates uas tsim los ntawm cov txheej txheem ib txwm muaj.
3. Lub npe ntawm cov khoom ESP yog qhov tsis meej pem, thiab tsis muaj kev pom zoo tiav.
