Kushanda maitiro e Vacuum mhepo choto

Vacuum atmosphere furnace tekinoroji yakazara inosanganisa vacuum tekinoroji uye kupisa kurapwa. Zvinoreva kuti zvose uye chikamu chekugadzirisa kupisa kunoitwa munzvimbo yevacuum. nyika yangu inokamura vacuum kuita yakaderera, yepakati, yakakwira uye yepamusoro-yepamusoro vacuum. Parizvino, iyo yekushanda vacuum yeakawanda emhepo furnaces ndeye 1.33 ~ 1.33 × 10ˉ3Pa.

Iyo vacuum yemhepo yevira inogona kupotsa maitiro ese ekurapa kupisa, sekudzima, kumisa, kupisa, carburizing uye nitriding. Mukuita kudzima, inogona kuona kudzimwa kwegasi, kudzima mafuta, kudzima nitrate, kudzima mvura, nezvimwe, pamwe nekuvharisa brazing. , Sintering, kurapwa kwepamusoro, nezvimwe.

Choto chine hunyanzvi hwekushisa, chinogona kukurumidza kupisa uye kutonhora, haigone kuwana oxidation, hapana decarburization, hapana carburization, inogona kubvisa phosphorus machipisi pamusoro peiyo workpiece, uye ine mabasa ekudzikisa uye kubvisa gasi, kuitira kuti uwane. mhedzisiro yekucheneswa kwakajeka kwepamusoro. Kazhinji kutaura, iyo yakagadziridzwa workpiece inodziiswa zvishoma nezvishoma muvacuum yemhepo muchoto, iyo yemukati yekupisa mutsauko idiki, kushushikana kwekupisa kudiki, uye deformation idiki.

Panguva imwecheteyo, chiyero chakakodzera chevacuum atmosphere furnace zvigadzirwa zvakakwirira. Inogona kuderedza mari uye ine degassing effect, nekudaro inovandudza mashandiro emakanika uye hupenyu hwebasa rebasa. Nzvimbo yekushanda yakanaka, kushanda kwakachengeteka, uye hapana kusvibiswa uye kusvibiswa. Iko hakuna njodzi yehydrogen embrittlement yeyakagadziriswa workpiece, uye pamusoro pehydrogen embrittlement inodzivirirwa kune titanium uye refractory simbi mabhomba, uye kugadzikana uye kudzokororwa kwemhepo muchoto muitiro wakanaka. Neiyi nhevedzano yemabhenefiti, kuvandudzwa kwemidziyo yevira remumhepo uye tekinoroji yakabhadharwa zvakanyanya uye zvakanyanya kutariswa uye zvakanyanya uye zvakanyanya kushandiswa zvakanyanya.
