Kodi choviikidwa mu hot-rolled, choviikidwa mu cold-rolled, ndi kusiyana pakati pa ziwirizi?

 

1. Kugubuduza Kotentha
Ma slabs opitilira kapena ma slabs oyambira ozungulira ngati zopangira, otenthedwa ndi ng'anjo yotentha yoyendera, kuponderezedwa kwa madzi othamanga kwambiri mu mphero yozungulira, zinthu zozungulira podula mutu, mchira, kenako mu mphero yomaliza, kukhazikitsa kugwedezeka kolamulidwa ndi kompyuta, kugwedezeka komaliza komwe kumachitika pambuyo pa kuzizira kwa laminar flow (kuzizira kolamulidwa ndi kompyuta) ndi kupotoza makina ozungulira, kumakhala ma rolls owongoka a tsitsi. Mutu ndi mchira wa coil yolunjika tsitsi nthawi zambiri zimakhala ndi mawonekedwe a lilime ndi mchira wa nsomba, makulidwe, kulondola kwa m'lifupi kumakhala koipa, nthawi zambiri kumakhala m'mphepete wooneka ngati mafunde, m'mphepete wopindika, nsanja ndi zolakwika zina. Kulemera kwake ndi kolemera, m'mimba mwake wamkati wa coil yachitsulo ndi 760mm. (Makampani ambiri opanga chitoliro amakonda kugwiritsa ntchito.) Chozungulira tsitsi cholunjika pogwiritsa ntchito mutu wodula, mchira, m'mphepete wodula ndi kuwongola kopitilira kamodzi, kulinganiza ndi zina zomaliza, kenako kudula mbale kapena kubwerezanso, zomwe zimapangitsa kukhala: mbale yachitsulo yotentha yozungulira, ma coils achitsulo otentha ozungulira, mzere wodula wautali ndi zinthu zina. Ma coils otsiriza otentha ozungulira ngati pickling achotsa khungu la oxide ndikudzola mu coil yotentha yozungulira yozungulira. Chithunzi chili pansipa chikuwonetsachozungulira chotentha.

 

2. Wozizira Wozungulira
Ma coil achitsulo otentha opindidwa ngati zinthu zopangira, pambuyo pochotsa khungu la oxide kuti lizizizira, chinthu chomalizidwa cha voliyumu yolimba yopindidwa, chifukwa cha kusintha kosalekeza kwa kuzizira komwe kumachitika chifukwa cha kuuma kozizira kwa voliyumu yolimba yopindidwa, kuuma, kulimba ndi kuchepa kwa zizindikiro za pulasitiki, kuwonongeka kwa magwiridwe antchito, kungagwiritsidwe ntchito kokha pakusintha kosavuta kwa ziwalo. Chozungulira cholimba chingagwiritsidwe ntchito ngati zinthu zopangira chomera chotenthetsera madzi otentha, chifukwa chipangizo chotenthetsera madzi otentha chimayikidwa ndi mzere wothira madzi. Kulemera kwa chozungulira cholimba nthawi zambiri kumakhala matani 6 ~ 13.5, m'mimba mwake wa chozungulira ndi 610mm. Chozungulira chozungulira chozizira chonse, chozungulira chiyenera kukhala chopitilira kulowetsa madzi (CAPL unit) kapena chithandizo cha ng'anjo chotsekedwa ndi hood, kuti muchotse kuuma kozizira ndi kupsinjika kwa kugwedezeka, kuti mukwaniritse mawonekedwe amakina omwe afotokozedwa muzizindikiro zokhazikika. Ubwino wa pamwamba pa mbale yachitsulo yozizira, mawonekedwe, kulondola kwa miyeso ndikwabwino kuposa mbale yotentha yopindidwa. Chithunzi chotsatira chikuwonetsakoyilo yozizira yozungulira.

 

Kusiyana kwakukulu pakati pachitsulo chokulungidwa chozizira poyerekeza ndi chitsulo chotentha chokulungidwaPali ukadaulo wokonza zinthu, kuchuluka kwa momwe zimagwiritsidwira ntchito, mawonekedwe a makina ndi mtundu wa pamwamba, komanso kusiyana kwa mitengo. Izi ndi zomwe zafotokozedwa mwatsatanetsatane:
Kukonza. Kugubuduza kotentha kumachitika kutentha kwambiri, pomwe kugubuduza kozizira kumachitika kutentha kwa chipinda. Kugubuduza kotentha kumapitirira kutentha kwa crystallization, pomwe kugubuduza kozizira kumapitirira kutentha kwa crystallization.

 
Kugwiritsa Ntchito: Chitsulo chokulungidwa chotentha chimagwiritsidwa ntchito makamaka m'mapangidwe achitsulo kapena m'zigawo zamakanika, kuphatikizapo kumanga mlatho, pomwe chitsulo chokulungidwa chozizira chimagwiritsidwa ntchito kwambiri m'makampani opanga magalimoto kapena m'zida zazing'ono, makina ochapira, mafiriji, ndi zina zotero, kuphatikizapo zipangizo zomangira.

 
Kapangidwe ka makina. Kapangidwe ka makina ozunguliridwa ndi ozizira nthawi zambiri kamakhala bwino kuposa kotentha, chifukwa njira yozunguliridwa ndi ozizira imapangitsa kuti kuuma kapena kuuma kuzizira kukhale kozizira, zomwe zimapangitsa kuti kuuma ndi mphamvu ya pamwamba pa pepala lozunguliridwa ndi ozizira zikhale zapamwamba, koma kulimba kwake kumakhala kotsika, pomwe kapangidwe ka makina ka pepala lozunguliridwa ndi otentha ndi kochepa kwambiri kuposa pepala lozunguliridwa ndi ozizira, koma limakhala ndi kulimba komanso kusinthasintha kwabwino.

 
Ubwino wa pamwamba. Ubwino wa kapangidwe ka pamwamba pa chitsulo chokulungidwa chozizira udzakhala wabwino kuposa chitsulo chokulungidwa chotentha, zinthu zokulungidwa zozizira zimakhala zolimba komanso zosalimba kwambiri, pomwe zinthu zokulungidwa zotentha zimakhala ndi pamwamba polimba komanso lokhala ndi mawonekedwe osalala.

 
Kukhuthala kwa mafotokozedwe. Ma coil ozungulira ozizira nthawi zambiri amakhala opyapyala kuposa ma coil ozungulira otentha, ndipo makulidwe a coil ozungulira ozizira amakhala pakati pa mamilimita 0.3 mpaka 3.5, pomwe ma coil ozungulira otentha amakhala pakati pa mamilimita 1.2 mpaka 25.4.

Mtengo: Kawirikawiri, kupukutira kozizira kumakhala kokwera mtengo pang'ono kuposa kupukutira kotentha. Izi zili choncho chifukwa kupukutira kozizira kumafuna kugwiritsa ntchito zida zamakono zokonzera zinthu komanso ukadaulo wovuta kwambiri, ndipo kupukutira kozizira kumatha kukhala ndi zotsatira zabwino pakukonza pamwamba, kotero kuti mtundu wa zinthu zopukutira zozizira nthawi zambiri umakhala wokwera, mtengo wake umakhala wokwera. Kuphatikiza apo, chitsulo chopukutira chozizira popanga zinthu chimafuna ukadaulo wokhwima kwambiri wokonza zinthu komanso zovuta kwambiri pakukonza, zida zopangira, mipukutu ndi zida zina ndizofunikira kwambiri, zomwe zingayambitsenso kukwera kwa ndalama zopangira.
