Simbi inotonhoramachira uye inotonhora-yakakungurutswa simbi coils inogadzirwa kubva inopisa-yakakungurutswa simbi coils, akakungurutswa pakamuri tembiricha pazasi recrystallization tembiricha, kusanganisira mahwendefa uye coils.Chii chinounzwa mupepa chinonzi ndiro yesimbi, inozivikanwawo sebhokisi kana kuti flat plate;kureba kwakareba, uye kunounzwa mumakoiri kunonzi simbi tambo, inozivikanwawo sekoiri.Vakafanana vakangonzi zvakasiyana.
Coil ndeyemhando yeplate musimbi, inonyatso kureba uye nhete uye inowanikwa mumipumburu yendiro yesimbi yakatetepa, rolls uye flat plate inenge iri pasuru yakachekwa.
Panyaya yezvitemerwa, ukobvu hwesimbi inotonhora yakakungurutswa simbi mune coil inowanzo 0.2-4mm, yakafara 600-2000mm, uye kureba 1200-6000mm, iyo density chaiyo inotsamira pane zvakatemwa zvesimbi inotonhora yakakungurutswa ndiro, asi pane zvinoenderana. .Kazhinji kutaura, density yekutonhora yakakungurutswa kabhoni simbi ndiro yakatenderedza 7.85g/cm3.
Muchiverengero cheformula inotevera: kureba X hupamhi X ukobvu X density, nekuda kwehuwandu hweyuniti yemagiramu, saka kazhinji inoda kuve yekutanga unit yezviri pamusoro kuita masendimita, isati yawedzera maverengero ekuenzanisa.
Simbi inotonhora yakakungurutswa coil (annealed state): inopisa yakakungurutswa coil inowanikwa nekunhonga, kutonhora kutenderedza, hood annealing, levelling, (kupedza).
1. Hunhu hwakanaka hwepamusoro
Mushure menguva zhinji dzekuumburudza uye kupisa kurapwa, iyo inotonhora yakakungurutswa coil ine yakatsetseka uye kunyange pamusoro pasina makwara ari pachena, ganda rine oxidized, burrs uye humwe hurema, hunogona kusangana nepamusoro zvinodiwa zvekugadzirisa pamusoro pezvinodiwa.
2. High dimensional kururama
Cold yakakungurutswa simbi inogadziriswa kuburikidza nemaitiro akawanda akadai sekunyatso kutonga kwedimensional chikamu, pa-line kudzora kweplate chimiro uye ukobvu panguva yekukunguruka, uye annealing, nezvimwewo, uye chimiro cheplate yavo uye kurongeka kwedimensional kunogona kusangana nemazvo zvinodiwa zvemaindasitiri akasiyana.
3. Stable mechanical properties
Cold rolled coil kana ichienzaniswa neyakajairika inopisa yakakungurutswa coil nekuti yakakungurutswa uye nekupisa-yakagadziriswa kakawanda, zviyo zvayo zvakanaka, yunifomu yemagetsi zvivakwa, nepo iine yakanaka inotonhora yekushanda zvivakwa, inogona kuwana yakakwira ductility uye kuoma kuitira kuti ive nehupamhi. zvakasiyana-siyana zvemaapplication.
1. Indasitiri yemidziyo yemumba
Cold rolled sheet simbi inogona kushandiswa kugadzira magomba uye zvimiro zvemidziyo yemumba senge magororo emuchina wokuwachisa, mapaneru emasuo efiriji, magomba emhepo anofefetera uye zvichingodaro.
2. indasitiri yemotokari
Cold-yakakungurutswa kabhoni simbi coil inogona kushandiswa kugadzira mapaneru emuviri, mapaneru emagonhi, mahodhi, marekeni emukwende uye zvimwe zvikamu zvemotokari, zvine kusimba uye kusimba.
3. indasitiri yekuvaka
Cold rolled coils inogona kushandiswa kugadzira mapaneru ekuvaka, zvivakwa zvesimbi, mateko edenga uye zvimwe zvinhu zvekuvaka, zvine ngura yakanaka uye kusapfeka.
4. Indasitiri yemuchadenga
Mashizha anotonhora akakungurutswa anogona kushandiswa kugadzira mabhomba endege, zvikamu zveinjini uye zvimwe midziyo yemuchadenga.
Inopisa yakakungurutswa ine plastiki yakanaka, iri nyore kuumba, haina kushushikana kwemukati mushure mekuumba simbi, nyore kugadzirisa zvinotevera maitiro.Zvakadai sekugadzirwa kwesimbi mbariro, inoshandiswa kutsika mahwendefa esimbi, kugadzirwa nemichina uye kupisa-kupisa simbi inopisa-yakakungurutswa.Cold yakakungurutswa nebasa rinotonhora rinoomesa zvinhu.Nekuda kwekutonhora kwakakungurutswa kune zvirinani zvemichina, mazhinji akananga kushandiswa kwesimbi ari kushandisa inotonhora yakakungurutswa simbi.Zvakadai semasimbi anotonhora-akamonyoroka, waya yesimbi inotonhora, uye ndiro inotonhora inokungurutswa.
