Muindasitiri yemetallurgical, kushandiswa kwezvinhu zvemhando yepamusoro kwakakosha kuve nechokwadi chekugadzirwa kwakanaka uye kwakavimbika kwesimbi uye alloys. Pakati pezvinhu zvakasiyana-siyana zvakashandiswa, graphite crucibles yakawana mukurumbira wakakosha nekuda kweiyo yakasarudzika corrosion resistance properties. Ichi chinyorwa chinoongorora corrosion resistance properties yegraphite cruciblesuye basa ravo rinokosha mumetallurgical process.
Corrosion Resistance yeGraphite Crucibles
Graphite, fomu yekabhoni, inoratidza kuramba kunoshamisa kurwiswa kwemakemikari uye tembiricha yakakwira, zvichiita kuti ive chinhu chakanakira macrucibles muindasitiri yesimbi. Iyo corrosion resistance ye graphite crucibles inonzi inokonzerwa nemhando dzakasiyana dze graphite pachayo. Graphite ine hunhu husingadzokerike, hunoita kuti isaite nemaasidhi mazhinji, alkalis, uye zvimwe zvinhu zvinopisa zvinosangana nazvo panguva yekunyunguduka kwesimbi nekugadzira alloy.
Acid Resistance:Graphite cruciblesratidza kuramba kwakanakisa kunzvimbo dzine acidic. Vanokwanisa kumira nekuora kweasidhi yakadai sesulfuric acid, hydrochloric acid, uye nitric acid. Hunhu uhwu hwakakosha mumatanho anosanganisira mabatirwo easidhi, senge kugadzirwa kwemamwe simbi uye simbi oxides.
Alkali Resistance: Mukuwedzera kune acids,graphite crucibleskuratidza kushorwa kune alkalis. Alkaline zvinhu, zvakaita sesodium hydroxide uye potassium hydroxide, zvinowanzoshandiswa mune dzakasiyana siyana metallurgical application.Graphite cruciblesramba usingabatanidzwi neaya alkali, kuve nechokwadi chekuvimbika uye hupenyu hurefu hwecrucible panguva dzakadaro.
Oxidation Resistance: Graphite ine yakanakisa oxidation kuramba, kunyangwe pakupisa kwakanyanya. Kana iri pasi pekupisa kwakanyanya, graphite inoumba chidziviriro che graphite oxide pamusoro payo, iyo inoshanda sechipingamupinyi kurwisa kuwedzera oxidation. Ichi chivakwa chinonyanya kubatsira mukushandisa uko macrucibles anoratidzwa kune oxidizing mamiriro ekunze, sekunyungudika nekukwenenzvera kwesimbi.
Thermal Shock Resistance: Chimwe chinhu chakakosha chegraphite cruciblesndiko kupikisa kwavo kuvhunduka kwekupisa. Graphite ine yakakwira yekupisa conductivity uye yakaderera coefficient yekuwedzera kwekupisa, zvichiita kuti ikwanise kumira nekukurumidza kuchinja kwekushisa pasina kutsemuka kana kutyora. Uku kupokana nekuvhundutswa kwekupisa kwakakosha mumatanho anosanganisira kudzokororwa kupisa uye kutonhora kutenderera, sekukanda simbi uye kugadzirwa kwealloy.
Zvakanakira Graphite Crucibles
Iyo corrosion resistance properties yegraphite crucibles inopa mabhenefiti akati wandei muindasitiri yesimbi:
Hupenyu Hwakareba: Ma graphite crucibles ane hupenyu hurefu kana achienzaniswa neakareruka macrucibles akagadzirwa nezvinhu zvakaita sevhu kana ceramic nekuda kwekupokana kwazvo nekuora uye kuvhunduka kwemafuta.
Yakavandudzwa Chigadzirwa Hunhu: Iyo isiri-reactive chimiro chegraphite crucibles inova nechokwadi chekuti simbi yakanyungudutswa kana alloy inoramba isina kusvibiswa, zvichitungamira kune emhando yepamusoro zvigadzirwa.
Kushanda Kwesimba: Graphite crucibles ine yakanaka yekupisa conductivity, inogonesa kufambisa kupisa kwakanaka, kugovera tembiricha yakafanana, uye kuderedzwa kwesimba rekushandisa panguva yekunyungudika.
Mutengo-Kushanda: Kunyangwe pakutanga ichidhura pane zvimwe zvinorovera zvinhu, magraphite crucibles 'akawedzera hupenyu uye kuita kwepamusoro kunoita kuti ive sarudzo inodhura nekufamba kwenguva.
Mhedziso
Graphite crucibles inoita basa rakakosha muindasitiri yesimbi, ichipa yakasarudzika corrosion resistance properties, thermal shock resistance, uye oxidation kuramba. Kugona kwavo kumira nemamiriro akaomarara anowanikwa panguva yekunyunguduka kwesimbi uye kugadzirwa kwealloy kunoita kuti ive yakakosha mumhando dzakasiyana dzesimbi. Nekusarudza ma graphite crucibles, vagadziri vanogona kuve nechokwadi chekuvandudzwa kwemhando yechigadzirwa, kurebesa crucible hupenyu, kugona kwesimba, uye yakazara mutengo-kubudirira. Sezvo indasitiri yemetallurgical ichienderera mberi, magirafu crucibles acharamba ari akavimbika uye akakosha chikamu mukutsvaga inoshanda uye yemhando yepamusoro kugadzirwa kwesimbi.
