Cold rolling in recrystallization tembiricha iri pazasi inonzi inotonhora-yakakungurutswa, inopisa-yakakungurutswa coil seyakabikwa, inowanzoshandiswa mu acid pickling kubvisa oxide ganda mushure mekutonhora kukunguruka, chigadzirwa chakapedzwa chakaoma, nekuda kwekutonhora kwebasa kuoma kunokonzerwa ne deformation yekuenderera. kutonhora kutenderedza hard roll simba, kuwedzera kuomarara, kuomarara uye indekisi yepurasitiki yakadzikira, saka kuita kwechitambi kunozodzikira, kunogona kungoshandiswa kune nyore deformation yezvikamu.
Hard coil inogona kushandiswa seyakagadzirwa, inopisa dip galvanized fekitori yekupisa dip galvanizing unit Settings are annealed wire.
Yakaoma vhoriyamu uremu mu20 - kazhinji
40 matani, simbi coil, pakamuri tembiricha kuti rirambe richikungurutswa inopisa yakakungurutswa pickling mavhoriyamu.
Cold rolled chigadzirwa maficha: nekuti hapana mushure mekurapa annealing, kuomarara kwakakwira zvakanyanya (
HRB yakakura kupfuura makumi mapfumbamwe)
, mechanical processing performance haina kunaka, chete yakapusa ine directivity isingasviki 90 degree bend processing.

Cold akakungurutsa nzira yekugadzirisa.
Cold rolling iri pasi pemamiriro ekugadziriswa nendiro inopisa yekukungurusa, apo mukugadzira machining ekukungurutsira kuchaita tembiricha yesimbi, zvakadaro inonzi inotonhora rolling.
Nekuda kwekupisa kunotenderedzwa kuburikidza nekuenderera kunotonhora musiyano weinotonhora yakakungurutswa mukuita kwemakanika kushomeka, kuomarara kwakanyanya, saka kunofanirwa kupfuura nemu annealing kudzoreredza ma mechanic properties, pasina annealing yakaoma.
Hard coil inowanzo shandiswa kuita pasina kukotama, kutambanudza zvigadzirwa, 1.
Pazasi zero ukobvu pamativi ese eiyo yakaoma rombo rakanaka kana quadrilateral kukotama.
Cold yakakungurutswa kazhinji mushure mekurapwa kweanealing.
Inofanirwa kushandiswa mukuita kutonhora kutenderedza kutonhora kutenderedza oiri, mabhenefiti ekushandisa anotonhora anotenderedza mafuta ndeaya: 1, zvinonyatso dzikisa friction coefficient, inopa inoenderana inotenderedza simba, kutenderedza yakaderera simba rekushandisa, inogutsa inotenderera paramita;
2, ita kupenya kwepamusoro kwepamusoro uye ukobvu hwakafanana hwekunonoka kukunguruka;
3, yakanaka kutonhora mhedzisiro, inogona kukurumidza kubvisa inopisa kutenderera, kudzivirira roll uye chidimbu chinotenderedza.
Anealing performance yakanaka, haiburitse mafuta ekupisa chiitiko;
4, ine nguva pfupi-yenguva inopesana ne-rust performance, inogona kupa yenguva pfupi yekudzivirira ngura yezvidimbu zvakakungurutswa.
Inopisa yakakungurutswa inopisa-yakakungurutswa (

Ndeyekushanda kunopisa kwekukunguruka.
Kupisa kwakatenderedzwa kwakakwira kugadzirwa kwehunyanzvi, hukuru hukuru, kushomeka kwesimba, mutengo wakaderera, wakakwira dhigirii rekugadzira, otomatiki, yakakodzera kugadzirwa kwakawanda mumutsara, ndeimwe yeakanyanya kukosha simbi yekumanikidza kugadzirisa nzira.
Kupisa kwakatenderedzwa nekugadzirisa simbi deformation kuramba yakaderera uye mapurasitiki uye anoshandiswa zvakanyanya.
Asi sezvo tembiricha yakatenderedzwa isiri nyore kuenzana kana ichikunguruka, tin oxide pamusoro iripo, saizi yechigadzirwa uye kushata kwepamusoro zvinhu zvishoma zvinotonhora zvakakungurutswa.
Chigayo chikuru chekupisa chigayo.
Inoshandiswa muchigayo inopisa ine phyletic yakawanda, kune maviri roll mill, matatu roll mill, roll mill yekuuraya, ina high rolling mill, Y type rolling mill, two-high skew rolling mill, three-roll skew rolling mill. , cross rolling mill, universal mill nemarudzi ese ezvigayo zvakakosha zvichingodaro.
Zvinoenderana nezvinodiwa pakugadzirwa kwemhando dzakasiyana dzezvigadzirwa, mhando yechigadzirwa, kugadzirwa, mamiriro esaiti, nezvimwe, kune akawanda mafomu ekutenderedza mill yeanopisa anotenderedza workshop dhizaini, senge imwe muchina dhizaini, imwechete kana akawanda makoramu eyakavhurika chitima. kuronga, chirongwa chekutevera, rolling type dhizaini, chessboard mhando yakashongedzwa, nezvimwe.
Kupisa kutenderedza kugadzirwa kwemaitiro kunowanzo sanganisira kugadzirwa kwezvinhu, kudziyisa, kutenderedza, kupedzisa uye zvichingodaro akati wandei maitiro.
Hot rolling inogona kushandiswa kukungurutsa ingot yesimbi kana big billet, kugadzirwa kwehukuru hukuru zvigadzirwa.
Senge ingot hombe yekukungurutsira 70 t mukati nekutenderedza 50 t hombe billet, gadzira ukobvu hwe500 mm gobvu ndiro, isina musono pombi ye1070 mm mudhayamita, 1200 mm x 530 MMH simbi uye 78 kg/m njanji, nezvimwe.
Muchipisa chekukungurutsa, tembiricha yakatenderedzwa zvishoma nezvishoma inodzikira, deformation yemidziyo kuramba inowedzera zvishoma nezvishoma, pakupedzisira haigone kuita nzvimbo inopisa.
Saka haisi saizi yezvigadzirwa zvinopisa zvakakungurutswa zvingave zvidiki, zvinogona kungove 1 mm gobvu shizha rekukunguruka, 20 mm dhayamita seamless simbi pombi, dhayamita ye5.
0 mm waya, nezvimwewo.
Mutsara.
Saka haisi saizi yezvigadzirwa zvinopisa zvakakungurutswa zvingave zvidiki, zvinogona kungove 1 mm gobvu shizha rekukunguruka, 20 mm dhayamita seamless simbi pombi, dhayamita ye5.
0 mm waya, nezvimwewo.
Kupisa kutenderedza kunogona kuve nehukuru hwekugadzira, gore negore kuburitsa 6 miriyoni t ye rough rolling mill, kana iripo, ine gore negore kugona kwe6 miriyoni inopisa yakakungurutswa DaiGangChang nezvimwe.
Zvigadzirwa zvinopisa zvakatenderedzwa zvinogona kukamurwa nemuchinjika chimiro chimiro cheanopisa akakungurutswa tambo, inopisa yakakungurutswa seamless simbi pombi, inopisa yakakungurutswa simbi uye yakakosha simbi inopisa inotenderedza makirasi mana.
Kupisa kunotenderedzwa nekukunguruka nzira inonyanya kukamurwa kuita longitudinal rolling, skew rolling uye rolling.
Musiyano pakati peinotonhora yakakungurutswa uye inopisa yakakungurutswa, inotonhora yakakungurutswa muzvikamu 1 kubvumira yenzvimbo buckling chikamu, iyo inogona kushandisa zvizere bar buckling kutakura kugona mushure;
Local buckling uye inopisa yakakungurutswa simbi haibvumiri chikamu chemuchinjikwa.
2, izvo zvinokonzeresa inopisa yakakungurutswa simbi uye inotonhora yakakungurutswa simbi yakasara kushushikana kwakasiyana, saka kugoverwa kwechikamu chemuchinjikwa kunewo musiyano mukuru kwazvo.
Cold-formed thin-walled steel cross section pane yasara stress distribution yakakombama, uye inopisa yakakungurutswa simbi kana welded simbi yasara stress kuparadzirwa pamuchinjikwa chikamu ifirimu nhete.
3, simbi inopisa yakakungurutswa yemahara torsional rigidity yakakwira pane inotonhora yakakungurutswa simbi, saka torsion zvimiro zveinopisa-yakakungurutswa simbi iri nani pane inotonhora yakakungurutswa simbi.
