Moyo wautumiki wa graphite silicon carbide crucibles

Moyo wautumiki wagraphite silicon carbide cruciblesndichinthu chofunikira kuganizira mukamagwiritsa ntchito m'mafakitale osiyanasiyana. Ma crucibles amagwiritsidwa ntchito kwambiri posungunula ndi kuponyera njira m'mafakitale azitsulo ndi zoyambira. Kumvetsetsa zinthu zomwe zimakhudza moyo wautumiki wa ma crucibles ndikofunika kwambiri kuti ntchito yawo ikhale yolimba komanso yolimba.

Kutentha kwa ntchito kumagwira ntchito yofunika kwambiri pakuzindikira moyo wautumiki wa graphite silicon carbide crucibles. Kukwera kwa kutentha kwa ntchito, kumachepetsa moyo wautumiki wa crucible. Izi ndichifukwa choti ma crucibles amakumana ndi kupsinjika kwakukulu pa kutentha kwambiri ndipo amatha kusweka. Ndikofunikira kugwiritsa ntchito ma crucibles mkati mwa kutentha komwe akulimbikitsidwa kuti atsimikizire kuti moyo wautali wautumiki ndi kupewa kulephera msanga.

Kuchuluka kwa ntchito kudzakhudzanso moyo wautumiki wa graphite silicon carbide crucible. Pambuyo pa ntchito iliyonse, ma crucibles amatha kuvala ndi dzimbiri, zomwe zimapangitsa moyo wawo wautumiki kuchepa pang'onopang'ono. Kuchuluka kwa ntchito kumakhudza mwachindunji moyo wautumiki wa crucible, kotero ndikofunikira kuyang'anira ndikuwunika mkhalidwe wa crucible pambuyo pa kuzungulira kulikonse. Kusamalira moyenera komanso kuyang'anira pafupipafupi kungathandize kukulitsa moyo wa crucible yanu ndikuwonetsetsa kuti ntchito yayitali komanso yokhazikika.

Chilengedwe chamankhwala chomwe crucible chimagwiritsidwa ntchito chimakhudza kwambiri moyo wake wautumiki. Ma graphite silicon carbide crucibles amawonetsa kukana kwa dzimbiri m'malo osiyanasiyana amankhwala. Kuwonetsedwa ndi zinthu zowononga kumathandizira kuwonongeka kwa crucible, zomwe zimapangitsa moyo waufupi wautumiki. Ndikofunika kusankha zinthu zoyenera zowonongeka pogwiritsa ntchito malo enieni a mankhwala omwe crucible idzagwiritsidwa ntchito kuti zitsimikizidwe kuti zikugwira ntchito bwino komanso kukhala ndi moyo wautali.

Momwe crucible imagwiritsidwira ntchito zimakhudzanso moyo wake wautumiki. Kugwiritsa ntchito molakwika, monga kuyika crucible ku kusintha kwadzidzidzi kutentha kapena kuika zinthu zozizira mmenemo, kungasokoneze kulimba kwake. Kusamalira moyenera ndikutsata njira zogwiritsiridwa ntchito zomwe zalangizidwa ndizofunikira kwambiri pakukulitsa moyo wovuta komanso kupewa kulephera msanga.

Kumanga ndi kupanga zigawo za oxide mkati mwa crucible zingakhudzenso ntchito yake ndi moyo wautumiki. Zinthu izi zimatha kulepheretsa crucible kupirira kutentha kwambiri komanso malo owononga, zomwe zimapangitsa kuti moyo ukhale waufupi. Kuyeretsa nthawi zonse ndi kukonza kungathandize kuchepetsa zotsatira za adhesion ndi oxide mapangidwe, ndikuthandizira kukulitsa moyo wa crucible yanu.

Powunika moyo wautumiki wa graphite silicon carbide crucibles, ndikofunikira kuganizira momwe mungagwiritsire ntchito komanso momwe mungagwiritsire ntchito. Moyo weniweni wautumiki ukhoza kusiyanasiyana kutengera zinthu monga njira yogwiritsira ntchito, kutentha, malo opangira mankhwala, komanso kuchuluka kwa ntchito. Kuyesa mozama ndi kuunika m'malo omwe akugwiritsidwira ntchito kungapereke chidziwitso chofunikira pa moyo wautumiki woyembekezeredwa wa crucible.

Ma graphite silicon carbide crucibles athu adapangidwa kuti azipereka magwiridwe antchito odalirika komanso moyo wautali wautumiki mumitundu yosiyanasiyana yosungunuka. Akagwiritsidwa ntchito kusungunula aluminium, ma crucibles athu amapereka moyo wautumiki wa miyezi 6-7, pamene amagwiritsidwa ntchito kusungunula mkuwa, moyo wautumiki ndi pafupifupi miyezi itatu. Popereka chidwi chapadera pakugwiritsa ntchito, kutentha kwa ntchito ndi malo opangira mankhwala, ma crucibles athu amatha kukulitsa moyo wawo wautumiki, kupereka magwiridwe antchito okhazikika, ogwirira ntchito pamafakitale osungunuka ndi kuponya.
