Idla ngokusetyenziswa kwishishini lentsimbi, ngokuchasene ne-coil eshushu.Ibhekisela kumgca wensimbi ogqitywe kwi-thickness ethile ngokuthe ngqo ngumqulu kwaye ujikeleze kumqulu wonke nge-winder kwiqondo lokushisa eliqhelekileyo.Xa kuthelekiswa nekhoyili eshushu esongwayo, umphezulu wekhoyili oqengqelekayo oqaqambileyo, ukugqiba okuphezulu, kodwa uya kuvelisa ngakumbi uxinzelelo lwangaphakathi, rhoqo emva konyango lokuqengqeleka olubandayo.
Ngenxa yokuba akukho kufudumala kwinkqubo yokuvelisa, akukho ziphene ze-pitting kunye ne-oxide sheet ezihlala zivela kwi-hot rolling, kwaye umgangatho womphezulu ulungile kwaye ukugqiba kuphezulu.Ngapha koko, ukuchaneka komgangatho weemveliso eziqengqelekayo ziphezulu, kwaye iipropathi kunye nolungelelwaniso lweemveliso zinokuhlangabezana neemfuno ezithile, ezinjengeepropathi zombane, iipropathi ezinzulu zokuzoba, njl.
