Njira yopanga

Njira yopangira yotentha yotenthakoyilo yachitsulondi chida chofunikira pakupanga zitsulo. Zimapanga kwambiri billet yachitsulo mu mawonekedwe ofunikira a mbale kupyolera mu kutentha kwakukulu. Zotsatirazi ndi zake zazikulu:

Kukonzekera Zakuthupi
Zopangira zake zimakhala ngati slab mosalekeza kapena pachimake, pafupifupi 150-300 mm wandiweyani.
Pansi pa slab amatsuka (mwachitsanzo, kuwotcha moto kapena kugaya ndi makina) kuti achotse sikelo ndi zolakwika kuti zitsimikizire kugudubuza.
Kutentha
Silabu imadyetsedwa mu ng'anjo yamtengo woyenda ndikutenthedwa mpaka 1100-1300 ° C kuti ifike ku austenitization ndikuwongolera ductility.
Kutentha nthawi ndi kufanana kwa kutentha kuyenera kuyendetsedwa kuti zisatenthe kapena kutentha pang'ono.
Zovuta
Silabu amakulungidwa m'mipiringidzo yapakati 30-50 mm wokhuthala mu mphero yokhotakhota (mwachitsanzo, mphero yotalika ziwiri kapena zinayi).
Pambuyo pa kugubuduza kulikonse, kutsika kwamadzi othamanga kwambiri kumatha kuchitidwa kuti muchotse wosanjikiza wa oxide pamwamba.
Kumaliza
Mipiringidzo yapakatikati imalowa mu mphero yomaliza (yomwe imakhala ndi mphero zisanu ndi ziwiri kapena zisanu ndi ziwiri kapena zisanu ndi chimodzi), pomwe imachepetsedwa pang'onopang'ono mpaka makulidwe a chandamale (mwachitsanzo, 1.2-25 mm) kudzera mukugudubuza kosalekeza. Automatic gauge control (AGC) ndi machitidwe owongolera ma flatness amagwiritsidwa ntchito kuwonetsetsa kulondola komanso kusalala.
Pakugubuduza, mipukutuyo imafunika kuziziritsa ndi kuthira mafuta kuti zisawonongeke komanso kuvala.
Kuziziritsa
Dongosolo lozizira la laminar limaziziritsa mwachangu chingwe chachitsulo kuchokera ku kutentha komaliza (pafupifupi 800 ° C) mpaka kutentha kwa chipinda poyang'anira kuchuluka kwa madzi ndi kuzizira (mwachitsanzo, 30-50 ° C / sekondi).
The kuzirala ndondomeko mwachindunji zimakhudza microstructure (mwachitsanzo, ndi ferrite kuti pearlite chiŵerengero) ndi makina katundu wa koyilo.
Kuzungulira
Mzere wachitsulo umakulungidwa muzozungulira pogwiritsa ntchito pinch rolls ndi coiler. Kulimbanako kumayendetsedwa pakati pa 100-500 N/mm² kuti muwonetsetse mawonekedwe olimba komanso osasunthika.
Kutentha kozizira nthawi zambiri kumayendetsedwa pakati pa 550-700 ° C kuti kukhathamiritsa katundu.
Pambuyo pokonza
Kuchiza pamwamba: Chithandizo chapamwamba chimaphatikizapo pickling kuchotsa sikelo ya oxide kapena zokutira monga galvanizing kapena aluminizing.
