Sei mamwe maovheni ekupisa anonyanya kupisa anosarudza ma electrode e graphite sezvinhu zvinodziisa?

Mamwe mavacuum heater anosarudza ma graphite electrodes sezvinhu zvinodziisa nekuda kwekubatsira kwakazara kwe graphite mumamiriro ekupisa kwakanyanya, zvichiita kuti ive sarudzo yakakodzera yezvinhu zvinodziisa muvacuum heater. Ongororo chaiyo ndeiyi inotevera:

1. Kuramba Kupisa Kwakakwirira: Nzvimbo Yekunyunguduka Uye Kugadzikana Kwekupisa kweGraphite
   Graphite ine poindi yekunyunguduka inosvika 3,652°C uye inogona kushanda zvakadzikama pamusoro pe2,000°C munzvimbo dzine vacuum cleaner, ine mimwe michina yepamusoro inosvika 2,200°C. Kudzivirira kupisa kwakanyanya uku kunoita kuti ikwanise kutsungirira mamiriro ekupisa akanyanya, zvichiita kuti ive yakakodzera kushandiswa mukugadzira zvinhu zvakaita sesimbi dzinopisa kana kuti dzinochinja-chinja zvinhu zveceramics dzinoshanda zvakanaka uye simbi dzisingashande zvakanaka. Kusiyana neizvi, zvinhu zvinopisa zvesimbi zvinowanzo pfava kana kuputika pakupisa kwakanyanya, nepo graphite ichiramba iine simba rayo remuchina pasi pe2,500°C uye inotopfuura maoxide nesimbi dzese pa1,700°C.

2. Kugadzikana kweMakemikoro: Kuramba Kuora uye Kuoxidation muVacuum Environments
   Mumamiriro ezvinhu evacuum, uko huwandu hwemagasi anooxidating senge oxygen hwakaderera zvakanyanya, kuramba kweoxidation kwegraphite kunovandudzika zvakanyanya. Pamusoro payo hapanyanyi kuumba oxide layers, zvichidzivirira kuora kwekushanda kana kupera kweelectrode kunokonzerwa neoxidation. Pamusoro pezvo, graphite inodzivirira ngura zvakanyanya kune akawanda maacid, alkalis, uye munyu, zvichiita kuti ive yakakodzera kugadzirisa zvinhu zvine kuchena kwakanyanya (semuenzaniso, semiconductors, magnetic materials) uye kudzivirira kusvibiswa kana shanduko mukugadzirwa kwemakemikari.

3. Kufambisa Kwekupisa: Kupisa Kwakanaka Uye Kwakafanana Nekuchengetedza Simba
   Graphite inyanzvi yekupisa yakanakisa, inopfuura zvinhu zvakawanda zvesimbi mukutamisa kupisa. Mumachoto evacuum, maelectrode egraphite anogona kukurumidza kuendesa kupisa kuzvinhu zvakagadzirwa, zvichipfupisa nguva yekupisa uye zvichiwedzera kushanda zvakanaka kwekugadzira. Panguva imwecheteyo, chiyero chayo chidiki chekuwedzera kupisa (kuchinja kushoma kwehukuru panguva yekupisa nekutonhodza) chinoita kuti kupararira kwekupisa kwakafanana, nekusiyana kwekushisa kwechoto kuchidzorwa mukati me ±5°C, kudzivirira kutsemuka kwezvinhu kana kushanduka nekuda kwekupisa kwakanyanya kana kutonhora kusina kuenzana. Uyezve, hunhu hwe graphite hwekuputira kupisa hunoderedza kurasikirwa nekupisa, zvichideredza kushandiswa kwesimba.

4. Kuramba Kupisa Nekuvhunduka: Kuchinjika Kukurumidza Kupisa Uye Kutonhodza
   Graphite inodzivirira kupisa zvakanyanya, inoramba kupisa nekutonhora nekukurumidza pasina kutsemuka kana kuchinja. Izvi zvinoita kuti ive yakakodzera kune mamwe maitiro anoda shanduko dzekupisa nekukurumidza, senge kurapwa kwegraphitization yekupisa kwakanyanya, ukuwo ichiwedzera hupenyu hwebasa re electrode.

5. Zvakanakira zveMaumbirwo uye Kugadziriswa: Kuchinjika uye Kuchinjika kweMagadzirirwo
   Maelectrode eGraphite anogona kugadzirwa nemazvo achishandisa matekiniki eCNC akanyatsogadzirwa kuita maumbirwo akasiyana-siyana (semuenzaniso, tsvimbo dzinodziya, mibhedha yefurnace, maguides) kuti akwane marudzi akasiyana efurnace uye zvinodiwa pakuita basa. Kuchinjika kwavo uye nyore kwekuisa kunoderedza kuoma kwekugadzirwa kwemidziyo. Pamusoro pezvo, maelectrode eGraphite anogona kushanda mabasa akawanda sezvinhu zvinodziya, thermal insulation layers, uye support structures, zvichiita kuti zvive nyore kuvaka mukati memafurnace evacuum.

6. Kuchenesa Nzvimbo Yevacuum: Dhizaini Yesisitimu Yakareruka
   Mumagumbeze evacuum, trace carbon inoburitswa kubva kuma graphite electrodes inopindirana ne residual oxygen ne water vapor mu gasi, zvichipa kuchenesa. Izvi zvinoderedza kuomarara uye mutengo we vacuum system, mukana mukuru mumabasa anoda vacuum conditions yakakwira zvakanyanya.

7. Mabhenefiti Ezvehupfumi Nezvakatipoteredza: Kushanda Nesimba Kwemari Kwenguva Refu Uye Kutevedzera Mutemo
   Kunyangwe mutengo wekutanga wema graphite electrodes ungave wakakwira kupfuura mamwe ma electrodes esimbi, hupenyu hwawo hwekushanda kwenguva refu, zvinodiwa zvishoma zvekugadzirisa, uye kushanda nesimba zvinoderedza zvakanyanya mari yekushandisa kwenguva refu. Uyezve, graphite haina radioactive uye yakagadzikana pakupisa kwakanyanya, ichizadzisa mitemo yezvakatipoteredza uye ichidzivirira kuburitswa kwemhepo kunokuvadza.
