Kuvandudza Kuchengetedzeka kweIndasitiri uye Kubudirira neKushandisa Kwakafanira kweGraphite Crucibles

Mumakore achangopfuura, kushandiswa kwegraphite cruciblesmumaindasitiri kunyungudusa uye kukanda simbi kwave kuwedzera zvishoma nezvishoma, nekuda kweceramic-based dhizaini inopa kusarudzika kwepamusoro-tembiricha kuramba.Nekudaro, mukushandiswa kunoshanda, vazhinji vanofuratira yakakosha preheating maitiro ezvitsva zvegraphite crucibles, zvichitungamira kune njodzi dzinogona kuitika kune wega uye pfuma kuchengetedzwa nekuda kwekutsemuka kwakatsemuka.Kuti tiwedzere zvikomborero zve graphite crucibles, tinopa mazano ezvesayenzi ekushandiswa kwavo kwakakodzera, kuve nechokwadi chekugadzirwa kwakanaka uye kuchengetedzwa kwemaindasitiri.

Hunhu hweGraphite Crucibles

Graphite crucibles inoita basa rakakosha mukunyungudusa simbi uye kukanda nekuda kwekunaka kwavo kwekushisa.Nepo ivo vachiratidzira zvirinani kupisa conductivity zvichienzaniswa nesilicon carbide crucibles, ivo vanotapukirwa neoxidation uye vane mwero wepamusoro wekuputsika.Kuti ugadzirise nyaya idzi, zvakakosha kushandisa hunyanzvi hwesainzi preheating process.

Preheating Guidelines

1. Kuisa pedyo neOiri Furnace ye Preheating: Isa crucible pedyo nechoto chemafuta kwemaawa 4-5 usati watanga kushandiswa.Iyi preheating process inobatsira mukubvisa humidification, kuwedzera kugadzikana kwecrucible.
2. Kupisa Marasha kana Huni: Isa marasha kana huni mukati memuchairi uye pisa kweanenge maawa mana.Iyi nhanho inobatsira mukubvisa humidification uye inovandudza iyo crucible yekudzivirira kupisa.
3. Furnace Temperature Ramp-up: Panguva yekutanga kupisa chikamu, zvishoma nezvishoma wedzera tembiricha muchoto zvichienderana neanotevera nhanho tembiricha kuti uve nechokwadi chekugadzikana uye hupenyu hurefu hweiyo crucible:
   • 0 ° C kusvika 200 ° C: Kupisa zvishoma nezvishoma kwemaawa mana (choto chemafuta) / magetsi
   • 0°C kusvika 300°C: Kudziisa zvishoma nezvishoma kweawa imwe (magetsi)
   • 200°C kusvika 300°C: Kudziisa zvishoma nezvishoma kwemaawa mana (choto)
   • 300°C kusvika 800°C: Kudziisa zvishoma nezvishoma kwemaawa mana (choto)
   • 300°C kusvika 400°C: Kudziisa zvishoma nezvishoma kwemaawa mana
   • 400 ° C kusvika 600 ° C: Kukurumidza kupisa, kuchengetedza kwemaawa maviri
4. Post Shutdown Reheating: Mushure mekuvhara, nguva yekudziisa yemafuta nemagetsi emagetsi yakaita seinotevera:
   • 0°C kusvika 300°C: Kudziisa zvishoma nezvishoma kweawa imwe
   • 300°C kusvika 600°C: Kudziisa zvishoma nezvishoma kwemaawa mana
   • Pamusoro pe600°C: Kupisa nekukasika kusvika kune tembiricha inodiwa

Shutdown Guidelines

• Pamavira emagetsi, zvinokurudzirwa kuchengetedza kuvharidzira kunoramba kuripo kana kusina basa, nekushisa kwakagadzirirwa kutenderera 600 ° C kudzivirira kutonhora nokukurumidza.Kana insulation isingaite, bvisa zvinhu kubva mucrucible kuti uderedze zvakasara zvemukati.
• Kwemavira emafuta, mushure mekuvhara, ita shuwa kuburitsa zvinhu zvakanyanya sezvinobvira.Vhara chivharo chechoto uye zviteshi zvekufefetera kuti uchengetedze kupisa kwasara uye kudzivirira hunyoro hunoputika.

Nekuomerera kune aya akaiswa pasi pesainzi preheating nhungamiro uye kuvharika kwekudzivirira, kuita kwakaringana kwemagraphite crucibles mukugadzirwa kwemaindasitiri kunogona kuvimbiswa, panguva imwe chete ichiwedzera kugadzirwa kwekugadzira uye kuchengetedza kuchengetedzwa kwemaindasitiri.Ngatizvipirei pamwe chete kune hunyanzvi hwekuvandudza tekinoroji kufambisa kufambira mberi kwemaindasitiri.
