Njira yopangira coil yachitsulo chotenthedwa ndi chinthu chofunikira kwambiri popanga zitsulo. Imapanga makamaka chipolopolo chachitsulo kukhala mawonekedwe ofunikira a mbale kudzera mu kugwedezeka kwa kutentha kwambiri. Izi ndi njira zake zazikulu:
Kukonzekera Zinthu Zopangira
Gwiritsani ntchito billet yopangira yopitilira kapena billet yoyambira yopangira ngati zopangira, ndipo makulidwe a billet nthawi zambiri amakhala 150-300mm.
Chidebecho chimatsukidwa pamwamba (monga kutsuka malawi kapena kupukusa makina) kuti chichotse oxide scale ndi zolakwika kuti zitsimikizire kuti zikuyenda bwino.
Kutentha
Chidebecho chimatumizidwa ku ng'anjo yotentha yoyendera pansi ndipo chimatenthedwa kufika pa 1100-1300 ℃ kuti chidebecho chifike kutentha kowonjezereka ndikuwonjezera kusinthasintha.
Yang'anirani nthawi yotenthetsera ndi kutentha komwe kumafanana kuti mupewe kutentha kwambiri kapena kutentha kosakwanira.
Kuzungulira Koyipa
Kukhuthala kwa billet kumachepetsedwa kufika pa 30-50mm kudzera mu mphero yozungulira yosinthika (monga mphero ya ma roll awiri kapena ma roll anayi) kuti apange billet yapakati.
Kuchotsa madzi opanikizika kwambiri kungachitike pambuyo pa kusuntha kulikonse kuti muchotse pamwamba pa oxide wosanjikiza.
Kumaliza Kuzungulira
Chikwama chapakati chimalowa mu mphero yomaliza (nthawi zambiri mphero 6-7 zokhala ndi mipukutu inayi kapena mipukutu isanu ndi umodzi), ndipo pang'onopang'ono chimachepetsedwa kufika pa makulidwe oyenera (monga 1.2-25mm) kudzera mu kugwedezeka kosalekeza.
AGC (automatic thickness control) ndi dongosolo lowongolera mawonekedwe a mbale zimagwiritsidwa ntchito kuti zitsimikizire kulondola kwa miyeso ndi kulunjika kwa mawonekedwe a mbale.
Ma rollers ayenera kuziziritsidwa ndi kupakidwa mafuta akamazungulira kuti kutentha kusamasinthe komanso kutha.
Kuziziritsa
Dongosolo loziziritsira laminar limagwiritsidwa ntchito kuziziritsa msanga chingwe chachitsulo kuyambira kutentha komaliza kozungulira (pafupifupi 800℃) mpaka kutentha kwa chipinda mwa kulamulira kuchuluka kwa madzi ndi liwiro loziziritsira (monga 30-50℃/s).
Njira yozizira imakhudza mwachindunji kapangidwe kake (monga chiŵerengero cha ferrite ndi pearlite) ndi mphamvu za makina a coil yachitsulo.
Kuzungulira
Chingwe chachitsulo chimakulungidwa mu coil yachitsulo kudzera mu pinch roller ndi coiler, ndipo mphamvu imayendetsedwa pa 100-500N/mm² kuti zitsimikizire kuti mawonekedwe a coil ndi olimba ndipo palibe coil yotayirira.
Kutentha kwa coil nthawi zambiri kumayendetsedwa pa 550-700℃ kuti kugwire bwino ntchito.
Chithandizo Chotsatira
Chithandizo cha pamwamba: pickling yochotsa oxide scale, kapena galvanizing, aluminiyamu plating ndi mankhwala ena opaka.
Kuphimba: kumawonjezera kusinthasintha kwa zinthu (monga kubwezeretsanso mphamvu ya crystallization annealing musanayike mufiriji).
Kusalala: kuchotsa nsanja yopezera phindu ndikukonza mawonekedwe a pamwamba kudzera mu kusuntha pang'ono.
Kuyang'anira ndi kulongedza bwino: yang'anani kukula, mawonekedwe a makina ndi mtundu wa pamwamba, ndipo pindani, phatikizani ndi kuyika chizindikiro malinga ndi zosowa za makasitomala.
