Nzira dzekudzivirira oxidative decarburization ye choto chemagetsi chekuedza workpieces

1. Surface coating paste

Iyo nzira yekuputira paste pamusoro peiyo workpiece yakaderera mumutengo, iri nyore mukushanda, uye haidi yakakosha michina.

Kunyangwe iyo nzira yekuisa paste iri nyore uye iri nyore, pane njodzi yekupwanya uye kupenengura paste panguva yekupisa, iyo inogona kuramba ichikonzera yemuno oxidation uye decarburization. Panguva imwecheteyo, iyo paste iripo pamusoro peiyo workpiece, iyo inokanganisa kunaka kwekudzima, uye iyo yakadzimwa workpiece haisi nyore kuchenesa. Uye, chidimbu chebasa chakaputirwa nenamira chichaunza hutsi hwakawanda kana inopisa, iyo inokanganisa kushandiswa kwechoto chemagetsi.

2. Kufukidzwa kwehupfu hwemarasha

Shandisa marasha ehupfu, kana kuwedzera chiyero chakakodzera chesimbi filings uye slag (saizi yezviyo 1 ~ 4mm) kuhupfu hwemarasha sechidziviriro chekudzivirira, kufukidza workpiece uye kupisa muchoto, iyo inogona kunyatso kudzivirira workpiece kubva kune oxidizing decarburization reaction. Iyi nzira iri nyore uye iri nyore kushandisa, uye mari yakaderera, asi nguva yekupisa inoda kuwedzerwa zvakakodzera.

3. Kudzivirirwa kweakakosha-shaped workpieces

Kune mamwe akasarudzika-akaumbwa workpieces, zvakaoma kudzivirira oxidative decarburization nekuisa coating kana marasha poda coating. Panguva ino, humwe hupfu hwemarasha hunogona kuiswa muchoto netirayiti, uye ipapo kutonhora kwechoto kunogona kuwedzerwa kusvika kune yakakwirira. Tembiricha inofanirwa kunge yakakwira kupfuura 30 ~ 50 ℃, kuitira kuti marasha adyidzane nemhepo kuti abudise huwandu hwakakwana hwekabhoni, kuitira kuti gasi riri muchoto ive munzvimbo isina kwayakarerekera, uyezve ma workpiece akakosha anotakurwa, anogona kuderedza kana. kudzivirira chiitiko che oxidative decarburization.
