CHII CHINONZI Stainless Steel?
Simbi isina tsvina isimbi uye chromium alloy. Nepo isina tsvina ichifanirwa kunge iine inosvika 10.5% chromium, iyo chaiyo zvikamu uye zviyero zvichasiyana zvichienderana negiredhi rakumbirwa uye chinangwa chekushandiswa kwesimbi.
KUGADZIRWA KWASIMBA KWESIMBA
Nzira chaiyo yegiredhi resimbi isina tsvina ichasiyana mumatanho ekupedzisira. Kuti giredhi resimbi rakaumbwa sei, rinoshanda uye rakapedzwa sei rinoita basa rakakosha pakuona kuti rinotaridzika sei uye rinoita sei.
Usati wagadzira chigadzirwa chesimbi chinotakurika, unofanirwa kutanga wagadzira iyo yakanyungudutswa alloy.
Nekuda kweizvi mamakisi mazhinji esimbi anogovana matanho ekutanga.
Danho 1: Kunyunguduka
Kugadzira simbi isina tsvina kunotanga nekunyungudusa simbi dzakaraswa nezvinowedzerwa muvira remagetsi arc (EAF). Ichishandisa magetsi emagetsi epamusoro, EAF inopisa simbi mukati memaawa akawanda kugadzira musanganiswa wakanyungudutswa, wemvura.
Sezvo simbi isina simbi iri 100% inogona kushandiswazve, akawanda maodha asina tsvina ane zvakawanda se60% simbi yakadzokororwa. Izvi zvinobatsira kwete kudzora mitengo chete asi kuderedza kukanganisa kwezvakatipoteredza.
Kupisa chaiko kuchasiyana zvichienderana negiredhi resimbi yakagadzirwa.
Danho 2: Kubvisa Carbon Content
Carbon inobatsira kuwedzera kuoma uye kusimba kwesimbi. Nekudaro, kabhoni yakawandisa inogona kuunza matambudziko-akadai sekunaya kwecarbide panguva yewelding.
Usati wakanda simbi yakanyungudutswa isina tsvina, kuenzanisa uye kudzikiswa kwekabhoni yemukati kusvika padanho rakakodzera kwakakosha.
Pane nzira mbiri dzinowanikwa dzinodzora kabhoni yemukati.
Yekutanga ndeyeArgon Oxygen Decarburization (AOD). Kupinza argon gasi musanganiswa musimbi yakanyungudutswa kunoderedza kabhoni nekurasikirwa kushoma kwezvimwe zvinhu zvakakosha.
Imwe nzira inoshandiswa ndeye Vacuum Oxygen Decarburization (VOD). Nenzira iyi, simbi yakanyungudutswa inoendeswa kune imwe kamuri umo okisijeni inopinzwa musimbi uku kupisa kuchiiswa. Vacuum inobva yabvisa magasi anobuda mukamuri, zvichiwedzera kuderedza kabhoni.
Nzira mbiri idzi dzinopa kutonga kwakaringana kwekabhoni kuti ive nechokwadi chekusanganiswa kwakakodzera uye hunhu chaihwo mune yekupedzisira simbi isina tsvina chigadzirwa.
Danho rechitatu: Tuning
Mushure mekudzikisa kabhoni, kuenzanisa kwekupedzisira uye homogenization yekushisa uye chemistry kunoitika. Izvi zvinova nechokwadi chekuti simbi inosangana nezvinodiwa zvegiredhi yayakada uye kuti kuumbwa kwesimbi kunoenderana mubatch yese.
Mienzaniso inoedzwa uye inoongororwa. Kugadziriswa kunobva kwaitwa kusvikira musanganiswa wasangana nechiyero chinodiwa.
Nhanho 4: Kugadzira kana Kukanda
Nesimbi yakanyungudutswa yakagadzirwa, muvambi unofanirwa kugadzira chimiro chekare chinoshandiswa kutonhodza nekushanda simbi. Chimiro chaicho uye zviyero zvinoenderana nechigadzirwa chekupedzisira.
