Kutakura pombi rudzi rwemusono simbi pombinekupisa-yakaputirwa kana kutonhora-yakaputirwa ( inotonhorera yakadonhedzwa), inoshandiswa kugadzira zvindori zvinotakura zvakajairika.Iyo yekunze dhayamita yepombi inowanzoita 25-180 mm uye nemadziro ukobvu hwe3.5-20 mm.Kutakura simbi inoshandiswa kugadzira bhora, roller uye zvindori zvinotakura zvesimbi.Bearings inoshanda pasi pekumanikidzwa kukuru uye kukweshana, inoda yakakwirira uye yunifomu inotakura kuomarara kwesimbi uye kupfeka kuramba, uye yakakwirira elastic muganho.Kutakura simbi kemikari kuumbwa kufanana, isiri-metallic inclusion content uye kugovera, kugoverwa kwecarbides nezvimwe zvinodiwa zvakanyanya kuoma zvinodiwa zvekugadzirwa kwesimbi mune imwe yemhando dzinonyanya kudiwa dzesimbi.

Kutakura simbi ine yakakwira kunyunguduka zvinodiwa zvinodiwa, panguva iyi, uye zvinoda zvakasimba kudzora sarufa, phosphorus, hydrogen kugutsikana, uye asiri simbi inclusions uye carbides nhamba, kukura uye kuparadzirwa, asiri simbi inclusions uye carbides sezvo nhamba, saizi uye kugovera sevhisi hupenyu hweiyo inotakura simbi pesvedzero huru, kazhinji inotakura kukundikana iri muhombe carbide inclusions kana madiki-akatsemuka anogadzirwa kutenderedza kuwedzera kune.Inclusions content uye oxygen content musimbi yakanyatsoenderana nepamusoro peokisijeni yemukati, iyo yakawanda nhamba ye inclusions, hupenyu hupfupi hunotarisirwa.Uye carbide inclusions yakakura particle size, yakawanda yunifomu kugovera, iyo ipfupi yehupenyu hwesevhisi, uye saizi yavo, kugovera uye kushandiswa kwekunyungudutsa uye kunaka kwekunyungudutsa kwakabatana zvakanyanya, iko zvino kubereka kugadzirwa kwesimbi pamwe nekuita kukuru ndiko kuenderera. kukanda EAF + ESR kunyungudutsa maitiro, pamwe nediki diki revacuum induction vacuum arc kaviri vacuum kana + inodzokororwa vacuum consumable uye imwe tekinoroji yekuvandudza kunaka kwekubereka simbi.

Sezvo kutakura kunofanira kuva nehupenyu hurefu, kunyatsojeka, kupisa kwakadzika, kukurumidza kukuru, kusimba, kuderera kweruzha, kupfeka kwepamusoro uye mamwe maitiro, saka zvinoda kuti pombi inotakura inofanira kuva ne: kuoma kwepamusoro, kuoma kweyunifomu, yakakwirira elastic muganho, yakakwirira. kubata kuneta simba, kunofanirwa kuomarara, kuomarara kunofanirwa kunge kuri mumhepo yemhepo inodzivirira yerubricant.Kuti uwane izvi zvinodikanwa zvekuita, iyo kemikari yesimbi mabearings homogeneity, isiri-metallic inclusion yemukati uye mhando, saizi uye kugovera kwecarbides, decarburization inoda.Yese inotakura simbi kusvika kumhando yepamusoro, kuita kwepamusoro uye kutungamira kwemhando dzakawanda.Kutakura simbi zvinoenderana nehunhu uye nharaunda yekushandisa yakakamurwa kuita: yakakwira kabhoni chromium inobereka simbi, carburizing inotakura simbi, tembiricha inotakura simbi, simbi isina tsvina uye yakakosha inotakura zvinhu zvakakosha.Kuti usangane nepamusoro-tembiricha, yakakwirira-kumhanya, yakakwira mutoro, ngura, anti-radiation zvinodiwa, inoda kukudziridza mutsara wekuita kwakakosha kwesimbi itsva inotakura.Kuti uderedze huwandu hweokisijeni yesimbi inotakura, kuvandudzwa kwevacuum smelting, electroslag remelting, electron beam remelting inobereka simbi yekunyungudutsa tekinoroji.Huwandu hukuru hwekubereka simbi inonyungudutswa nearc kunyunguduka, kuvandudza kuve marudzi ese ekutanga eCanada yekunatsa choto.
