Zvinogona kuita sezviri pachena kuti kuziva kwekushandisa kunogona kubatsira kudzivirira kushandisa zvakanyanya kupfuura zvinodiwa pazvigadzirwa.Inogonawo kuchengetedza nguva nemari pakuwedzera kugadzirisa.Mune mamwe mazwi, kunzwisisa mutsauko pakati pesimbi inopisa uye inotonhora yakakungurutswa ichabatsira vanogadzira uye mainjiniya kuwana mhedzisiro iri nani-uye pamutengo wakanakisisa unobvira.

Musiyano mukuru pakati pemhando mbiri idzi dzesimbi ndeimwe yemaitiro.Sezvaungafungidzira,“kupisa kukunguruka”zvinoreva kugadzirisa kunoitwa nekupisa.“Cold rolling”zvinoreva maitiro anoitwa patembiricha yemumba.Kunyangwe matekiniki aya achikanganisa kuita kwese uye mashandisirwo, haafanire kuvhiringika neakamisikidzwa uye mamakisi esimbi, ayo ane chekuita nemetallurgical kuumbwa uye kuita ratings.Simbi dzemagiredhi akasiyana uye zvirevo zvinogona kunge zvichipisa zvakakungurutswa kana kutonhora zvakakungurutswa-kusanganisira yakakosha kabhoni uye mamwe masimbi alloy.

Hot Rolled Steel

Simbi inopisa yakakungurutswa yakatsikirirwa pakupisa kwakanyanya (kupfuura 1,700˚F), iyo iri pamusoro pekushisa kwe-crystallization kune akawanda masimbi.Izvi zvinoita kuti simbi ive nyore kugadzira, uye inoguma mune zvigadzirwa zviri nyore kushanda nazvo.

Kugadzira simbi inopisa yakakungurutswa, vagadziri vanotanga nehombe, rectangular billet.Iyo billet inopisa uye inotumirwa kune pre-processing, iyo inoputirwa mumupumburu mukuru.Kubva ipapo, inochengeterwa pakupisa kwepamusoro, uye simbi inopenya-inopisa inofambiswa kuburikidza neyakatevedzana yekumanikidza rollers kuti iwane zviyero zvayo zvakapedzwa.Pamashizha esimbi, vagadziri vanoruka simbi yakamonerwa kuita makoiri vosiya kuti itonhore.Kune mamwe mafomu, akadai semabhawa uye mahwendefa, zvinhu zvakakamurwa uye zvakaputirwa.

Simbi inodzikira zvishoma sezvainotonhora.Nekuti simbi inopisa yakakungurutswa yakatonhodzwa mushure mekugadziriswa, pane kushomeka kwekutonga pamusoro pechimiro chayo chekupedzisira, zvichiita kuti isanyanya kufanirwa nemashandisirwo chaiwo.Simbi inopisa yakakungurutswa inowanzoshandiswa kana mitezo chaiyo isina't yakakosha-munjanji uye muzvirongwa zvokuvaka, somuenzaniso.

Simbi inopisa yakakungurutswa inogona kazhinji kuzivikanwa neanotevera maitiro:

•Scaled surfaces, zvisaririra zvekutonhodza kubva pakupisa kwakanyanya.

•Zvishoma zvakatenderedzwa mipendero uye makona ezvigadzirwa zvebhari neplate (nekuda kwekuderera uye kushomeka kupedzisa).

•Kukanganisa kudiki, uko kutonhora kunogona kusiya zvishoma trapezoidal mafomu pane kuti anyatso mativi emakona.

Simbi inopisa yakakungurutswa kazhinji inoda kugadziridzwa kushoma pane inotonhora yakakungurutswa, izvo zvinoita kuti idhure zvakanyanya.Kupisa kwakaputirwa simbi inobvumidzwawo kutonhora pakamuri tembiricha, saka izvozvo's chaizvo zvakajairika, zvichireva kuti's isina kushushikana kwemukati kunogona kumuka panguva yekudzima kana kushanda-kuomesa maitiro.

Simbi inopisa yakakungurutswa yakanakira uko kushivirira kwedimensional't yakakosha sesimba rezvinhu zvese, uye uko kupera kwepamusoro kusipo'ta key concerned.Kana kupera kwepamusoro kuri kunetseka, kuyera kunogona kubviswa nekukuya, kuputika kwejecha, kana kunyura-asidhi yekugezera.Kana kuyera kwabviswa, akasiyana brashi kana girazi kupera anogona kuiswa.Descaled steel inopawo nzvimbo iri nani yekupenda uye mamwe machira epamusoro.

Cold Rolled Steel

Cold yakakungurutswa simbi inopisa yakakungurutswa simbi yakapfuura nekumwe kugadzirwa.Kuti vawane simbi inotonhora yakakungurutswa, vagadziri vanowanzotora simbi yakatonhodzwa-inopisa voikungurutsira zvakanyanya kuti vawane hukuru chaihwo uye hunhu huri nani hwepamusoro.

Asi izwi“yakakungurutswa”inowanzoshandiswa kutsanangura nzira dzekupedzisa dzakadai sekushandura, kukuya, uye kupukuta, imwe neimwe inoshandura iripo inopisa yakamonerwa muzvigadzirwa zvakanatswa.Nehunyanzvi,“chando chakakunguruka”inoshanda chete kumashiti anodzvanywa pakati pema rollers.Asi mafomu akaita semabhawa kana machubhu ari“kudhonzwa,”kwete kukungurutswa.Saka mbariro dzinopisa dzakakungurutswa uye machubhu, kana atonhodzwa, anogadziriswa kuita anonzi“kutonhora kwapera”machubhu nembariro.

Cold rolled steel inogona kazhinji kuzivikanwa neanotevera maitiro:

•Mamwe mapeji akapedzwa ane kushivirira kuri pedyo.

•Nzvimbo dzakapfava dzinowanzova nemafuta kusvika pakubata.

•Mabhawa ndeechokwadi uye akaenzana, uye kazhinji ane akatsanangurwa mipendero nemakona.

•Machubhu ane zvirinani concentric kufanana uye kutwasuka.

Nehunhu huri nani hwepamusoro pane simbi inopisa yakakungurutswa, iyo'Hazvishamisi kuti simbi inotonhora inokungurutswa inowanzo shandiswa kune zvakanyanya hunyanzvi hwekushandisa kana uko aesthetics yakakosha.Asi, nekuda kwekuwedzera kwekugadziriswa kwezvinhu zvinotonhora zvapera, zvinouya nemutengo wepamusoro.

Panyaya yehunhu hwavo hwemuviri, kurapwa kunoshanda kunotonhora kunogonawo kugadzira kushushikana kwemukati mukati mechinhu.Nemamwe mashoko, kugadzira inotonhora yakashanda simbi-kungave nokuicheka, nokukuya, kana nokuchipisa-inogona kusunungura kusawirirana uye kutungamirira kuhondo isingatarisirwi.

Zvichienderana nezvauri'rekutsvaga kuvaka, mhando dzakasiyana dzezvishandiso imwe neimwe ine mabhenefiti ayo uye zvinokanganisa.Kumapurojekiti akasiyana kana kugadzirwa kumwe chete, zvigadzirwa zvesimbi zvakagara zvakagadzirirwa zvinogona kupa zvivharo zvekuvaka chero zvimiro zvegadziriso zvinofungidzirwa.

Kune mapurojekiti kwaunenge uchigadzira akawanda mayuniti, kukanda imwe sarudzo inogona kuchengetedza nguva mukugadzira uye kusangana.Zvikamu zvekukanda zvinogona kuitwa kunenge chero fomu mumhando yemhando yezvinhu.
