1400 – vharafu mhepo yemoto \ 1400 madigiri echokwadi sintering vira

Ndeapi mafufu emuchadenga mafesi? Vacuum atmosphere mavira anoverengerwa pa1000 ° C, 1200 ° C, 1400 ° C, 1700 ° C, 1800 ° C, 2000 ° C, nezvimwewo. Zvinoenderana neakasiyana tembiricha uye akasiyana atmospheres, akasiyana kudziyisa zvinhu zvinogona kusarudzwa, uye pa nguva imwechete, zvinhu zvakasiyana zvekudziya zvinogona kushandiswa. Yakakosha sintering yeakanyanya-tembiricha kuyedza kweichi chiitiko.

Iyo 1400 degree bhokisi-mhando yekutsvaira mhepo choto inoshandisa silicon carbide tsvimbo sezvinhu zvinopisa zvinhu, inotora yakangwara tembiricha yekudzora system, uye thyristor kutonga; choto chinoshandisa alumina polycrystalline fiber zvinhu, zvine yakanaka kupisa kuchengetedza maitiro; mbiri-rukoko girafu dhizaini nemhepo kutonhora uye Iyo mvura-inotonhorera system inogona kukurumidza kutonhora pasi, uye musuwo wevira unogadzirirwa nemvura-kutonhora kudzivirira iyo yekuisa chisimbiso mhete kubva mukukasira nekukurumidza, uye kuve nechokwadi chekunamatira chisimbiso chegedhi remoto uye choto.

Ndeipi yekutsvaira mhepo yevira mugadziri iri nani? 1400 ° C bhokisi-mhando vharuvhu mhepo inovhenekera, 1600 ° C vharuvhu molybdenum waya sintering choto, 2400 ° C vharafu tungsten chubhu sintering choto, 2200 ° C graphite yekutsvaira sintering choto, 2000 ° C tantalum kudziya choto.

Iyo vharuvhu mhepo inovhenekerwa inogona kubviswa uye akasiyana magasi, uye vharuvhu yekudzora ine yakarongedzwa yekudyira vharuvhu, yekuzadza vharafu, uye yevhavhavha yevhavha. Inogona kupfuudza akasiyana magasi, argon, nitrogen, uye oxygen. Iyo yevhavha system inotora mizhinji-nhanho O-mhando yekuisa chisimbiso, kupisa-kusagadzikana rabha gaskets kunovimbisa yakavimbika chisimbiso, diki vharu leakage, uye nyore mashandiro evhavha mamiriro mamiriro.

Kushanda nzvimbo yevhavha yemhepo muchoto:

Iyo yekutsiva yemhepo choto inogona kuiswa kune iyo kupisa kurapwa maitiro ezvigadzirwa zvemagetsi, zvitsva zvinhu uye hupfu zvinhu pasi pevhuvhu kana mhepo mamiriro. Iyo inoshandiswawo mune pre-kupfura, sintering, brazing uye mamwe maitiro ezvigadzirwa zvemagetsi zvedongo mune simbi, michina, indasitiri yakajeka, kuongorora zvigadzirwa, mayunivhesiti nemasainzi ekutsvagisa sainzi, mabhizimusi uye emabhizinesi emakambani.

Zvimiro zvevhavha yemhepo choto:

1. Bhokisi-rudzi rwemuchadenga unopikisa choto inotora yakapetwa-marara ganda chimiro, uye ndiro yeganda yemuviri bhokisi rakagadzirwa nemhando yepamusoro kabhoni simbi uye inotonhora-yakakungurutswa simbi simbi, iyo yakatemwa, yakapetwa, uye yakasungwa neyakajeka. CNC maturusi emuchina, iyo yakasimba uye yakasimba;

2. Iyo yekudziya element inotora silicon kabhoni tsvimbo, uye choto inotora alumina polycrystalline fiber zvinhu, iyo ine yakanaka kupisa kuchengetedza kuchengetedza, kusimba, yakakwira tensile simba, uye inovandudza zvakanyanya hupenyu hwebasa;

3. Inogona kubviswa uye inogona kupfuura munzvimbo dzakasiyana-siyana dzekudzivirira (kunze kwemagasi anopisa, anoputika, uye anoparadza zvakanyanya);

4. Otomatiki kumanikidzwa kumanikidzwa kwekudzvinyirira, yakanyanya tembiricha alarm uye kudzima magetsi, kudzivirira leakage, nyore kushanda;

5. Izvo ndezvokusarongeka kudzora iyo yekubvisa system, inflation system uye tembiricha yekudzvanya sisitimu kuburikidza neyekubata skrini yekushandisa nzira, iri nyore uye yakajeka.
