ST12 chitsulo chozizira kwambiri ndi chitsulo chotentha chomwe chakonzedwanso. Chitsulo chotentha chikazirala, chimakulungidwa kuti chikwaniritse miyeso yeniyeni komanso mawonekedwe abwino a pamwamba.
Cold rolled steel sheet (CR steel sheet) ndi chitsulo chotentha chomwe chakonzedwanso
Chitsulo chozizira 'chogudubuzika' chimagwiritsidwa ntchito kufotokoza njira zingapo zomalizitsira - komabe, mwaukadaulo, 'kuzizira kozizira' kumangogwira ntchito pamapepala omwe amapanikizana pakati pa odzigudubuza. Zinthu monga mipiringidzo kapena machubu 'amakokedwa,' osati kugudubuza. Njira zina zomaliza zozizira zimaphatikizapo kutembenuza, kugaya ndi kupukuta-chilichonse chimagwiritsidwa ntchito kusintha zinthu zomwe zilipo kale kuti zikhale zoyengedwa kwambiri.
ST12 ozizira adagulung'undisa koyilo yachitsulo nthawi zambiri amatha kudziwika ndi izi:
1.Cold adagulung'undisa zitsulo zili bwino, malo omalizidwa kwambiri ndi kulolerana kwapafupi
2.Pamalo osalala omwe nthawi zambiri amakhala amafuta mpaka kukhudza pazitsulo zachitsulo za CR
3.Mipiringidzo ndi yowona ndi yozungulira, ndipo nthawi zambiri imakhala ndi m'mphepete mwabwino komanso ngodya
4.Tubes ali ndi mawonekedwe abwino kwambiri komanso owongoka, opangidwa kuchokera kuzinthu zoziziritsa kuzizira.
5. Cold rolled steel coil yokhala ndi mawonekedwe abwino pamwamba kuposa chitsulo chotenthetsera chotentha, n'zosadabwitsa kuti chitsulo chozizira chozizira chimagwiritsidwa ntchito kwambiri mwaukadaulo kapena komwe kukongola kuli kofunikira. Koma, chifukwa cha kukonzanso kowonjezera kwa zinthu zozizira zomaliza, zimabwera pamtengo wapamwamba.
Potengera mawonekedwe awo, zitsulo zozizira zimakhala zolimba komanso zolimba kuposa zitsulo zotentha zotentha. Izi zili choncho chifukwa kutsirizitsa zitsulo zozizira kumapangitsa kuti pakhale chinthu chovuta kwambiri. Ndizofunikira kudziwa kuti mankhwala owonjezerawa amathanso kuyambitsa kupsinjika kwamkati mkati mwazinthuzo. Mwa kuyankhula kwina, popanga zitsulo zozizira—kaya kuzidula, kuzipera kapena kuziwotcherera—zikhoza kumasula mikangano ndi kuyambitsa kumenyana kosayembekezereka.
