Muchokwadi, mabheti esimbi kubva paguyo resimbi anongori semi-apedzwa zvigadzirwa, uye anofanirwa kukungurutswa muchigayo anokunguruka asati akwanisa kuva zvigadzirwa zvesimbi.Kupisa kukunguruka uye kutonhora kutenderedza zvinhu zviviri zvakajairika kukunguruka.Kukunguruka kwesimbi kunonyanya kupisa-kupisa, uye kutonhora-kunoputika kunonyanya kushandiswa kugadzira zvikamu zviduku uye mapepa.Izvi zvinotevera simbi inotonhora-yakakungurutswa uye inopisa-yakaputirwa: Waya: 5.5-40 mm muhupamhi, yakavharidzirwa, yose inopisa-yakaputirwa.Mushure mekudhirowa kunotonhora, ndeye inotonhora inodhonzwa zvinhu.Simbi yakatenderedzwa: Pamusoro pezvinhu zvinopenya zvine hukuru chaihwo, kazhinji inopisa-yakakungurutswa, uye kune zvakare zvinhu zvekugadzira (maki ekugadzira pamusoro).Strip simbi: ese ari maviri anopisa-akakungurutswa uye anotonhora-akakungurutswa, uye inotonhora-yakakungurutswa zvinhu zvinowanzo kutetepa.Simbi ndiro: inotonhora-yakakungurutswa ndiro kazhinji dzakatetepa, senge mahwendefa emotokari;kune akawanda anopisa-akakungurutswa epakati uye anorema mahwendefa, ane makobvu akafanana kune anotonhora-akakungurutswa, uye chitarisiko chavo chiri pachena chakasiyana.Angle simbi: yose inopisa yakakungurutswa.Simbi pombi: Zvose zvinopisa-zvakakungurutswa uye zvinotonhora-zvinodhonzwa zviripo.Channel simbi uye H-beam: inopisa yakakungurutswa.Reinforcing bar: inopisa yakakungurutswa zvinhu.
Ese ari maviri anopisa anokungururuka uye anotonhora kukungururuka maitiro ekugadzira mahwendefa esimbi kana maprofile, uye ane simba guru pane chimiro uye zvimiro zvesimbi.Kukunguruka kwesimbi kunonyanya kuenderana nekupisa kunopisa, uye kutonhora kutenderedza kunowanzo shandiswa chete kugadzirwa kwezvikamu zvidiki-diki uye mashizha ane chaiwo zviyero.Iyo tembiricha yekumisa yekutenderera inopisa kazhinji 800 kusvika 900 ° C, uyezve inotonhodzwa mumhepo, saka iyo inopisa yekutenderera mamiriro yakaenzana nekugadzirisa kurapwa.Masimbi mazhinji anokungurutswa nenzira inopisa yekukungurutsa.Nekuda kwekushisa kwakanyanya, simbi inounzwa munzvimbo inopisa-yakatenderedzwa ine musara wesimbi oxide sikeri pamusoro, saka ine kumwe kupikisa corrosion uye inogona kuchengetwa mumhepo yakashama.Nekudaro, iyi layer ye iron oxide scale inoitawo kuti pamusoro pesimbi inopisa-yakakungurutswa uye saizi inochinja zvakanyanya.Naizvozvo, iyo simbi ine yakatsetseka pamusoro, saizi chaiyo uye yakanaka michina zvimiro inodiwa, uye inopisa-yakakungurutswa semi-yakapedzwa zvigadzirwa kana zvakapedzwa zvigadzirwa zvinoshandiswa sezvigadziriso zvekutonhora kutenderedza kugadzirwa.Zvakanakira: kukurumidza kuumba kukurumidza, kuburitsa kwakakwira, uye hapana kukuvadzwa kwejasi, inogona kugadzirwa mumhando dzakasiyana-siyana dzepamuchinjikwa kuti isangane nezvinodiwa zvemamiriro ekushandiswa;kutonhora kunotonhora kunogona kukonzera kushanduka kukuru kwepurasitiki yesimbi, nekudaro kuvandudza goho resimbi point.Kukanganisa: 1. Kunyange zvazvo pasina kupisa kwepurasitiki kusungirirwa panguva yekugadzira, kuchine kusara kunetseka muchikamu, izvo zvichange zvichikanganisa maitiro ose uye emunharaunda buckling yesimbi;2. Chikamu chesimbi chinotonhora chinowanzova chikamu chakazaruka, zvichiita kuti chikamu chacho chisunungurwe.Torsional kuoma kwakaderera.Inowanzoita torsion panguva yekukotama, uye kukotama-torsional buckling inowanzoitika panguva yekumanikidza, uye kuita kwe torsional kwakashata;3. Ukobvu hwemadziro esimbi inotonhora-yakakungurutswa yekugadzira idiki, uye haina kuomeswa pamakona apo mahwendefa akabatanidzwa, saka inogona kumira kushushikana kwenzvimbo.Kugona kuisa pfungwa pamitoro hakuna simba.Cold rolling Kukunguruka (Cold rolling) zvinoreva nzira yekukunguruka yekushandura chimiro chesimbi nekuburitsa simbi nekutsikirira kwemupumburu patembiricha yekamuri.Kunyangwe iyo gadziriso ichipisawo simbi simbi, ichiri kunzi inotonhora rolling.Kunyanya, iyo inopisa-yakakungurutswa yesimbi coil yechando inotenderera inoshandiswa seyakaomeswa, uye iyo oxide chiyero inobviswa ne pickling, uye ipapo kudzvanywa kunoitwa, uye chigadzirwa chakapedzwa icoil yakaoma-yakatenderedzwa.Kazhinji, simbi inotonhora-yakakungurutswa senge galvanized simbi uye ruvara simbi ndiro inofanirwa kuvharirwa, saka plastiki uye kureba zvakare zvakanaka, uye inoshandiswa zvakanyanya mumotokari, midziyo yemumba, hardware uye mamwe maindasitiri.Kumusoro kwepepa rinotonhora-rakakungurutswa rine imwe dhigirii yekutsvedza, uye ruoko runonzwa runyoro, kunyanya nekuda kwekunhonga.Kupedzwa kwepamusoro peshizha rinopisa-rakakungurutswa kazhinji harizadzise zvinodiwa, saka simbi inopisa yakatenderedzwa inoda kutonhora-yakakungurutswa.The thinnest inopisa-yakakungurutswa simbi tambo kazhinji 1.0mm, uye inotonhora-yakakungurutswa simbi tambo inogona kusvika 0.1mm.Kupisa kutenderera kuri kutenderera pamusoro peiyo crystallization tembiricha poindi, uye kutonhora kutenderera kuri kuyerera pazasi peiyo crystallization tembiricha poindi.Shanduko yechimiro chesimbi nekukunguruka kunotonhora ndeyekuenderera kunotonhora deformation, uye kutonhora kuomarara kunokonzerwa nekuita uku kunowedzera kusimba, kuomarara uye kuoma uye epurasitiki index yeakakungurutswa coil yakaoma.Kuti upedze kushandiswa, kutonhora kutenderedza kunokanganisa kutsika zvivakwa, uye chigadzirwa chakakodzera kune akareruka deformation zvikamu.Zvakanakira: Inogona kuparadza chimiro chekukanda cheingot, kunatsa zviyo zvesimbi, uye kubvisa kukanganisa kweiyo microstructure, kuitira kuti chimiro chesimbi chive chakaoma uye michina yemagetsi inovandudzwa.Kuvandudzwa uku kunonyanya kuratidzwa mugwara rekukunguruka, kuitira kuti simbi haisisiri isotropic muviri kune imwe nhanho;iwo mabhubhu, kuputika uye porosity yakaumbwa panguva yekukanda inogona zvakare kusungirirwa pasi pechiito chekushisa kwakanyanya uye kudzvanywa.Kukanganisa: 1. Mushure mekupisa kunopisa, iyo isiri-metallic inclusions (kunyanya sulfides uye oxides, uye silicates) mukati mesimbi inomanikidzwa mumashizha matete, uye delamination inoitika.Delamination inoshatisa zvakanyanya kusimba kwesimbi kuburikidza neukobvu, uye pane mukana wekubvarura interlaminar sezvo weld inoderera.Nharaunda yemunharaunda inokonzerwa nekuderera kwe weld inowanzosvika kakawanda kune imwe nzvimbo yegoho, iyo yakakura zvikuru kupfuura iyo inokonzerwa nemutoro;2. Kushungurudzika kwakasara kunokonzerwa nekutonhora kusina kuenzana.Residual stress is the stress of internal self-phase equilibrium pasina simba rekunze.Kupisa-yakaputirwa chikamu simbi yezvikamu zvakasiyana-siyana ine kushushikana kwakasara kwakadaro.Kazhinji, iyo yakakura chikamu chechikamu chesimbi yechikamu, iyo yakanyanya kusara kunetseka.Kunyange zvazvo kushushikana kwakasara kuri kuzvidzora, kunoramba kune imwe simba pamusoro pekushanda kwenhengo yesimbi pasi pekuita kwesimba rekunze.Semuenzaniso, inogona kuva nemigumisiro yakaipa pa deformation, kugadzikana, uye kuramba kuneta.
