Pombi yesimbi inotonhora inogadzirwa nenzira inotonhora-yakakungurutswa.Cold-rolling iri pakamuri tembiricha kuti iwedzere kukungurutswa kune yakanangwa ukobvu hwendiro yakatetepa.Uye kuenzanisa yesimbi inopisa-yakakungurutswa, inotonhora yakakungurutswa simbi simbi ukobvu ndiyo yakanyatsojeka, uye pamusoro payo inotsvedzerera, yakanaka, asi zvakare ine akasiyana emhando yepamusoro michina zvinhu, kunyanya kugadzirisa mashandiro.Nekuti brittle inotonhora yakakungurutswa coil, haina kukodzera kugadzikiswa, saka mumamiriro ezvinhu akajairika inoda inotonhora-yakakungurutswa simbi pepa mushure mekuvhara, pickling uye kushata kwepamusoro kwakapihwa mutengi.Ukobvu hwepamusoro i0.1–8.0MM isingatonhore-yakakungurutswa, inotonhora-yakakungurutswa simbi ukobvu sezvo mazhinji emafekitori ari 4.5MM mashoma;Ukobvu hudiki, hupamhi hunoenderana nehukuru hwemidziyo uye kudiwa kwemusika kunotemerwa chirimwa chimwe nechimwe.

Cold yakakungurutswa simbi uye inopisa-yakakungurutswa simbi kunyungudutsa maitiro haasiyanise, asi pane kutenderedza tembiricha, kana kupisa kwekupedzisira tembiricha.Iyo yekupedzisira tembiricha yekutenderedza yakaderera pane recrystallization tembiricha yesimbi zvinhu inova iyo inotonhora-yakakungurutswa simbi.Easy rolling inopisa yakakungurutswa simbi, yakakwirira kukwenenzvera kunyatsoita, asi iyo oxidation yesimbi inopisa yakakungurutswa mamiriro, iyo chigadzirwa chepamusoro chakasviba grey rima.Inotonhora-yakakungurutswa simbi chigayo zvinodiwa simba, yakaderera kukungurukira kushanda, uye rolling maitiro kuitira kubvisa basa-kuomesa asiwo yepakati annealing, saka mutengo wakakwira, asi inotonhora-yakakungurutswa simbi inopenya pamusoro, yakanaka mhando, inogona kushandiswa zvakananga. yekugadzira zvigadzirwa zvakapedzwa, kunyanya simbi inotonhorera inoratidzirwa zvakanyanya.

Kupisa-yakakungurutswa simbi coil seyakagadzirwa, mushure mekutonhora kukungurutsa pickling descaling, chigadzirwa chakapedzwa chiri kukungurutsa mavhoriyamu, nekuda kwekuenderera mberi kwebasa kuoma kunokonzerwa nekutonhora deformation kukungurutsa mavhoriyamu akaoma esimba, kuomarara kwakawedzera kuoma kwepurasitiki index yakadonha.Naizvozvo kuita kwechitambi kunozodzikira, chete nekuda kwekuchinja kuri nyore kwezvikamu.Kukungurutsa mavhoriyamu akaomarara anogona kushandiswa sembatya yekupisa dip galvanizing chirimwa, nekuti inopisa dip galvanizing line inopihwa annealing line.Kutenderedza vhoriyamu yakaoma huremu kazhinji kubva pa6 kusvika 13.5 matani, simbi coils pakamuri tembiricha, inopisa-yakakungurutswa yakanyungudutswa coils yekuenderera ichikunguruka.Iyo yemukati dhayamita inosvika 610mm.
