NBS GH 48KW Yakazara Otomatiki Yemagetsi Heating Steam Jenareta inoshandiswa kune Steel Steam Oxidation Kurapa Maitiro

Muchoto chakazvigadzira chega chega, nzira yekurapa neutsi yeinowanzo shandiswa kabhoni 45# simbi yakadzidzwa, uye nzira yekukwenya, X-ray, SEM nedzimwe nzira dzakashandiswa kudzidza simba rekubatanidza, ukobvu, kuumbwa uye kuumbwa. yeiyo steam-treated surface oxide film.Hunhu hunoenderana.

Mhedzisiro yacho inoratidza kuti iyo yakanyanya kunaka yekurapa dhizaini kupisa pa570 ° C, inobata kwemaawa matatu, uye inodonha mvura pa 0.175ml/min.Simba rekubatana nefirimu rakasimba kudarika tsika yekusviba.Nekudaro, kuwanda kweiyo steam-treated oxide film yakashata kupfuura iyo yakasviba, uye mutoro wakakomba unodzikira sezvo nguva yekubata inowedzera pasi petembiricha yekudziya imwechete uye huwandu hwekudonha.

Chii chinonzi steam treatment?Ndezvipi zvikamu zvakakodzera kugadzirwa?Iyo inonzi steam treatment inzira iyo simbi inodziiswa mumhepo yakazadza pa540 kusvika 560 ° C kuti iite yunifomu, dense, yebhuruu remagineti Fe3O4 firimu rine ukobvu hwemamita maviri kusvika mashanu pamusoro pesimbi. .Iine kumira zvakanaka kuCorrosion uye anti-rust athari, uku ichivandudza hupenyu hwesevhisi yechishandiso.

Kubva pakuona kwekurapwa kweutsi, sezvo tembiricha yayo yekushanda iri pamusoro pe500 ° C, mutengo wayo wakakwirisa uye midziyo yekurapa yakakosha inodiwa.Nobis steam jenareta inogona kugadzirisa yakakwirira-tembiricha uye yakakwira-kudzvanya majenareta kuti agadzire yakakwira-tembiricha yakazara mutsi, inova Steam kurapwa kwezvikamu zvesimbi inogona kuwana mibairo mikuru!

High tembiricha uye high pressure steam jenareta

Nobeth yakakwirira tembiricha uye yakanyanya kudzvanywa steam jenareta ine akawanda mabasa.Nekuda kwehunhu hwayo hwekupisa, hunoshandiswa zvakanyanya mumaindasitiri akasiyana ekugadzira nekugadzirisa:

① Steam kurapwa ndiyo inonyanya kukodzera simbi yekumhanya uye yakakwirira-alloy simbi maturusi.Sezvo tembiricha yekupisa yezvishandiso zvesimbi zvekumhanya zvakanyanya ichienderana nazvo, iyo steam kurapwa maitiro zvakare inzira yekupisa.Panguva imwecheteyo, firimu reFe3O4 rinoumbwa, rinogona kuvandudza kusagadzikana kwekuora uye Hupenyu hwebasa ndeye 20% kusvika 30%.Inogona kudzivirira chizvarwa che oxide scale (Fe2O3 · FeO) muchoto chemhepo, kuve nechokwadi chekururama kwechigadzirwa.Carbon simbi uye general low-alloy simbi inokonzeresa kuderera kwekuomarara pane ino tembiricha, saka haina kukodzera kushandiswa.

② Inokodzera kurapwa kwepamusoro kwesilicon simbi mapepa, ayo anogona kuwana yakakura uye yunifomu yekupikisa kukosha, kuchengetedza yakakosha insulating pendi.

③Inokodzera anti-ngura uye gomba kuzadza kurapwa kwehupfu metallurgy kuvandudza kuoma kwayo uye kumanikidza simba.

④Inokodzera kurapwa kwepamusoro kwemamwe asiri-alloy workpieces kuti avandudze kuramba kwavo ngura.

⑤ Inokodzera kurapa kwepamusoro kwe screws uye nzungu dzakagadzirwa nekabhoni simbi kuti iwedzere kutaridzika uye anti-ngura kugona.

Nobeth high-temperature uye high-pressure steam jenareta anogadzirwa zvinoenderana nerudzi rwekumanikidza ngarava zviyero.Iwo akashongedzerwa nemapombi emvura akanyanya-kudzvanywa, anogona kuzadza mvura kana paine kumanikidza kwakanyanya mumudziyo.Iwo akanyanya-kumanikidza kuputika-uchapupu uye chiyero-isina magadzirirwo.Simba rinogona kugadziriswa zvachose.Izvo zviri nyore kushandisa, zvakachengeteka uye zvinobudirira!
