Pamusoro pendiro inotonhora ine kumwe kupenya uye inonzwa yakatsetseka, yakafanana nekapu yesimbi yakajairika inoshandiswa kunwa mvura.2. Kana ndiro inopisa yakakungurutswa isina kubikwa, inofanana nepamusoro pemahwendefa akawanda esimbi pamusika.Nzvimbo ine ngura yakatsvuka, uye pasi isina ngura ipepuru-dema (iron oxide).

Mabhenefiti ekuita kweanotonhora akakungurutswa pepa uye rinopisa rakatenderedzwa pepa ndeaya:

(1) kurongeka kwepamusoro, musiyano wekukobvu wechando chakakungurutswa tambo haina kupfuura 0.01 ~ 0.03mm.

(2) Saizi yakatetepa, iyo thinnest inotonhora inotenderera inogona kukungurutsa 0.001mm simbi tambo;Kupisa kutenderedza iko zvino kunosvika pahukobvu hudiki hwe 0.78mm.

(3) Hunhu hwepamusoro hwepamusoro, inotonhora yakakungurutswa simbi ndiro inogona kutogadzira girazi pamusoro;Iyo pamusoro pe inopisa - yakakungurutswa ndiro ine hurema hwakadai se iron oxide uye gomba.

(4) Pepa rinotonhora-rakakungurutswa rinogona kugadziridzwa zvinoenderana nezvinodiwa nemushandisi zvezvivakwa zvaro zvekumhanya senge tensile simba uye maitiro ekuita senge stamping zvivakwa.

Cold rolling uye inopisa kukunguruka imhando mbiri dzakasiyana dzesimbi yekukungurusa tekinoroji, sezvinoreva zita, kutonhora kutenderedza ndiko kusungira simbi pane tembiricha yekamuri, kuoma kwesimbi iyi yakakura.Kupisa ndiko kusungirirwa kwesimbi pamwe chete pakupisa kwakanyanya.Pepa rinopisa rakatenderedzwa rine kuomarara kwakaderera, kugadzirisa kuri nyore uye yakanaka ductility.Cold yakakungurutswa pepa kuoma kwakakwira, kugadzirisa kunenge kwakaoma, asi hazvisi nyore deformation, yakakwirira simba.Simba rinopisa rakakungurutswa ndiro rinenge rakaderera, mhando yepamusoro inenge (oxidation, yakaderera kupera), asi yakanaka plasticity, kazhinji yepakati gobvu ndiro, inotonhora yakakungurutswa ndiro: kusimba kwepamusoro, kuoma kwepamusoro, kupera kwepamusoro, kazhinji ndiro yakatetepa, inogona kushandiswa se stamping ndiro.Inopisa yakakungurutswa simbi ndiro, michina zvivakwa zvakaderera zvakanyanya kune inotonhora kugadzirisa, zvakare yakaderera kune yekugadzira kugadzirisa, asi ine nani kuoma uye ductility.Cold yakakungurutswa simbi ndiro nekuda kweimwe dhigirii yebasa kuomesa, kuomarara kwakaderera, asi inogona kuwana yakanaka flexural ratio, inoshandiswa kutonhora kupeta zvidimbu zvechitubu uye zvimwe zvikamu, panguva imwe chete nekuti iyo goho poindi iri padyo nesimba rekusimba, saka. kushandiswa kwengozi hakusi kufanotaura, kana mutoro unopfuura mutoro unobvumirwa unowanzoita njodzi.Netsanangudzo, ingot yesimbi kana billet yakaoma kutsvedza uye kugadzirisa pane tembiricha.Inowanzo kupiswa kusvika 1100 ~ 1250 ℃ yekukunguruka.Kukunguruka uku kunodaidzwa kuti hot rolling.Simbi zhinji inokungurutswa nekukunguruka kunopisa.Nekudaro, nekuti pamusoro pesimbi iri nyore kugadzira oxide sheet pakupisa kwepamusoro, pamusoro pesimbi inopisa yakakungurutswa ine hutsinye uye saizi inochinja zvakanyanya, saka simbi ine nzvimbo yakatsetseka, saizi chaiyo uye yakanaka michina zvinhu zvinodiwa, uye inopisa. akakungurutswa semi-apedzwa zvigadzirwa kana zvakapedzwa zvigadzirwa zvinoshandiswa seyakagadzirwa uye zvino kugadzirwa neinotonhora yekutenderedza nzira.Kukunguruka patembiricha yekamuri kunowanzo nzwisiswa sekutonhora kukunguruka.Kubva pakuona kwesainzi yesimbi, muganho uri pakati pekutonhora kukunguruka uye kupisa kunopisa kunofanirwa kusiyaniswa nekupisa tembiricha.Ndiko kuti, kukunguruka pazasi recrystallization tembiricha inotonhora kukunguruka, uye kutenderera pamusoro peiyo tembiricha recrystallization inopisa kukunguruka.Iyo tembiricha recrystallization yesimbi ndeye 450 ~ 600 ℃.Kupisa kutenderedza, sezvinoreva zita, kutenderedza zvikamu zvekushisa kwakanyanya, saka iyo deformation kuramba idiki, inogona kuwana yakakura deformation.Kutora ndiro yesimbi ichikunguruka semuenzaniso, ukobvu hwekuramba uchikandira billet hunenge 230mm, uye mushure mekukunguruka nekupedza kukunguruka, ukobvu hwekupedzisira ndeye 1 ~ 20mm.Panguva imwe chete, nokuti ukobvu reshiyo simbi ndiro idiki, dimensional kururama yakaderera, hazvisi nyore kuoneka chimiro dambudziko, kunyanya kudzora korona.Iyo microstructure uye michina zvimiro zve strip simbi inogona kudzorwa nekudzora tembiricha inotenderera, tembiricha yekutenderera uye tembiricha yecrimping.Cold rolling, kazhinji hapana nzira yekudziya isati yakunguruka.Nekudaro, nekuti iyo mitsetse ukobvu idiki, zviri nyore kuoneka dambudziko rechimiro.Uyezve, mushure mekutonhora kukungurutswa kwapera chigadzirwa, saka, kuitira kudzora kurongeka kwedimensional uye yemhando yepamusoro ye strip simbi, yakawanda inonetesa maitiro inoshandiswa.Cold rolling production line yakareba, yakawanda midziyo, yakaoma maitiro.Nekuvandudzwa kwezvido zvevashandisi pachiyero chedimension, chimiro uye nepamusoro mhando yestrip simbi, kune akawanda ekudzora modhi, L1 uye L2 masisitimu uye maitiro ekudzora maumbirwo muchigayo chinotonhora chinokunguruka pane chigayo chinopisa.Uyezve, tembiricha ye roller uye strip zvakare yakakosha kutonga index.Cold yakakungurutswa zvigadzirwa uye inopisa yakakungurutswa chigadzirwa pepa mutsara, ndiwo mutsauko pakati peiyo yapfuura maitiro uye inotevera maitiro, zvinopisa zvakakungurutswa zvigadzirwa ndizvo zvigadzirwa zvezvinotonhora zvakakungurutswa zvigadzirwa, inotonhora yakakungurutswa mushure mekunhonga inopisa yakakungurutswa simbi coil muchina uchishandisa roller chigayo, kukunguruka, zviri. kutonhora kugadzira kuumba, kunyanya kukungurutsa gobvu inopisa yakakungurutswa ndiro kuita yakatetepa dhizaini inotonhora yakakungurutswa ndiro, Kazhinji senge 3.0mm inopisa yakakungurutswa ndiro pamushini inokunguruka inogona kuburitsa 0.3-0.7mm inotonhora yakakungurutswa coil, musimboti mukuru kushandisa musimboti weextrusion. kumanikidzwa deformation.
