Zapamwamba Zapamwamba za Q235B Q345B Zomangira Zopangira Zitsulo Zotentha

Kufotokozera Kwachidule:

Koyilo yoyaka moto imatanthawuza kukanikiza kwa ma billets mu makulidwe ofunikira achitsulo pa kutentha kwambiri. Pakugudubuzika kotentha, chitsulo chimakulungidwa chikatenthedwa ku pulasitiki, ndipo pamwamba pamakhala oxidized ndi ovuta. Hot adagulung'undisa koyilo zambiri tolerances lalikulu dimensional ndi otsika mphamvu ndi kuuma, ndi oyenera zomangamanga nyumba, makina zigawo zikuluzikulu popanga, mapaipi ndi muli.

Njira yopanga

Njira yopangira zitsulo zotentha zotentha ndi njira yofunikira pakupanga zitsulo. Zimapanga kwambiri billet yachitsulo mumpangidwe wofunikira wa mbale kupyolera mu kutentha kwakukulu. Zotsatirazi ndi zake zazikulu:
Kukonzekera Zakuthupi
Gwiritsani ntchito billet mosalekeza kapena kugudubuza koyambirira ngati zopangira, ndipo makulidwe a billet nthawi zambiri amakhala 150-300mm.
Billet imatsukidwa pamwamba (monga kuyeretsa lawi kapena kugaya makina) kuchotsa oxide sikelo ndi zolakwika kuti zitsimikizire kugudubuza.
Kutentha
Billet imatumizidwa ku ng'anjo yowotchera masitepe ndikutenthedwa mpaka 1100-1300 ℃ kuti billet ifike kutentha kotentha ndikuwonjezera pulasitiki.
Yang'anirani nthawi yotentha ndi kufanana kwa kutentha kuti musatenthe kwambiri kapena kutentha kosakwanira.
Kugudubuzika Kwambiri
Kukula kwa billet kumachepetsedwa kukhala 30-50mm kudzera pa mphero yokhotakhota yosinthika (monga mipukutu iwiri kapena mphero zinayi) kuti apange billet yapakatikati.
Kutsika kwamadzi othamanga kwambiri kumatha kuchitika pakadutsa chiphaso chilichonse kuti muchotse wosanjikiza wa oxide pamwamba.
Kumaliza Rolling
Billet yapakatikati imalowa mu mphero yomaliza (kawirikawiri 6-7 gitala zinayi kapena zisanu ndi chimodzi), ndipo pang'onopang'ono imachepetsedwa mpaka makulidwe a chandamale (monga 1.2-25mm) kupyolera mosalekeza.
AGC (automatic makulidwe control) ndi dongosolo lowongolera mawonekedwe a mbale amagwiritsidwa ntchito kuwonetsetsa kulondola kwake komanso kuwongoka kwa mbale.
Zodzigudubuza zimayenera kuziziritsidwa ndi kuthiridwa mafuta panthawi yogubuduza kuti zisawonongeke komanso kuti zisamawonongeke.
Kuziziritsa
Dongosolo lozizira la laminar limagwiritsidwa ntchito kuziziritsa mwachangu chingwe chachitsulo kuchokera pakutentha komaliza (pafupifupi 800 ℃) mpaka kutentha kwa chipinda powongolera kuchuluka kwa madzi ndi kuzizira (monga 30-50 ℃/s).
Kuzizira kumakhudza mwachindunji microstructure (monga chiŵerengero cha ferrite ndi pearlite) ndi makina opangira zitsulo.
Kuzungulira
Mzere wachitsulo umakulungidwa mu koyilo yachitsulo kudzera pa pinch roller ndi coiler, ndipo kupsinjika kumayendetsedwa pa 100-500N/mm² kuonetsetsa kuti mawonekedwe a koyilo ndi olimba ndipo palibe koyilo yotayirira.
Kutentha kozizira nthawi zambiri kumayendetsedwa pa 550-700 ℃ kuti muwongolere magwiridwe antchito.
Chithandizo Chotsatira
Chithandizo chapamwamba: pickling kuchotsa oxide sikelo, kapena galvanizing, aluminiyamu plating ndi mankhwala ❖ kuyanika.
Annealing: Sinthani ductility zinthu (monga recrystallization annealing pamaso ozizira anagubuduza).
Kufewetsa: Kuchotsa nsanja yokolola ndikuwongolera kutsirizira kwapamwamba kudzera pakuwongolera pang'ono kochepetsa.
Kuyang'anira khalidwe ndi kulongedza: onani kukula, katundu makina ndi pamwamba khalidwe, ndi mpukutu, mtolo ndi chizindikiro malinga ndi zofuna za makasitomala.
