Chii chinonzi carburant?

Kune akawanda marudzi ema carburizers, anosanganisira marasha, echisikigo graphite, artificial graphite, coke uye zvimwe kabhoni zvinhu.Zviratidzo zvemuviri zvekuferefeta nekuyera macarburizers anonyanya kunyungudika, kukurumidza kunyungudika, uye nzvimbo yekubatidza.Iwo makuru emakemikari zviratidzo ndeye Carbon content, sulfur content, nitrogen content, uye hydrogen content.Sulfur nehydrogen zvinhu zvinokuvadza.Mukati mechikamu chakati, nitrogen chinhu chakakodzera.Mukugadzirwa kwesimbi yakakandwa yesimbi, iyo carburizer ine mhando iri nani inonzi Inonyanya kukosha ndeye graphitized recarburizer, nekuti pasi pemamiriro ekushisa kwakanyanya, maatomu ekabhoni akarongwa mune microscopic fomu yegraphite, saka inonzi graphitization.Carburizers inogona kuwedzera zvakanyanya huwandu hwesimbi yakarashwa inoshandiswa mukukanda, uye kuona kushandiswa kwesimbi shoma kana isina yenguruve.

Carburizer basa:
Carburizer chinhu chakakosha mbishi chekunyungudutsa simbi yakanyungudutswa muchoto chekupinza, uye hunhu hwayo uye mashandisiro zvinokanganisa kunaka kwesimbi yakanyungudutswa.Castings ane zvimwe zvinodikanwa zvekabhoni, saka carburizers anoshandiswa kuwedzera kabhoni yemukati musimbi yakanyungudutswa.Zvinhu zvinowanzo shandiswa muchoto mukunyungudutsa simbi yenguruve, simbi yakaraswa, uye zvinhu zvinogadzikiswazve.Kunyange zvazvo carbon content yenguruve iron yakakwirira, mari yacho inenge yakakwirira kudarika iyo yesimbi yakasakara.Nokudaro, kushandiswa kwerecarburizer kunogona kuwedzera kuwanda kwesimbi yakasvibiswa uye kuderedza huwandu hwesimbi yenguruve, kuitira kuti kuderedza mari yekukanda.
Classification ye carburizers:
Graphite recarburizer inoreva shanduko yemamorekuru ezvigadzirwa zvekabhoni kuburikidza nekushisa kwepamusoro kana dzimwe nzira, uye kune kurongeka kwenguva dzose.Mugadziriro iyi yemamorekuru, kureba kwema molecular kabhoni kwakapamhama, izvo zvinonyanya kubatsira pakuora uye kuumbwa musimbi yakanyungudutswa kana simbi.nuclear.Iwo magraphite recarburizer parizvino ari pamusika anowanzo kubva nenzira mbiri, imwe ndeye kucheka kwemarara emagetsi egraphite, uye imwe yacho ndeye graphitization chigadzirwa chepetroleum coke pa3000 degrees.

Coal-based carburizer chigadzirwa chinoverengerwa pasi petembiricha yepamusoro uchishandisa anthracite seyakagadzirwa.Iyo ine hunhu hwepamusoro yakagadziriswa kabhoni yemukati, yakasimba oxidation kuramba uye yakaderera yemukati yezvinhu zvinokuvadza.Inogona kushandiswa sechinhu chinoderedza muhutano hwekunyungudutsa.Munguva yekugadzira simbi yearc choto, coke kana anthracite inogona kuwedzerwa se carburizer paunenge uchichaja.
