Mu makampani opanga aluminiyamu osungunula ndi osungunula aluminiyamu,ma rotor a graphitezakhala pafupifupi zida zodziwika bwino. Mafakitale ambiri amadziwa bwino kuti popanda chophimba chotsutsana ndi okosijeni, rotor idzagwiritsidwa ntchito mwachangu. Chifukwa chake, "zophimba zosiyanasiyana zotsutsana ndi okosijeni" zadzaza msika. Komabe, pankhani ya malo enieni opangira zinthu, funso lodziwika bwino limabuka: chifukwa chiyani chophimbacho, chomwe chikuyenera kuteteza rotor ya graphite, nthawi zambiri chimakhala gawo loyamba kulephera pansi pa kutentha kwambiri, kwa nthawi yayitali, komanso koopsa? Akatswiri omwe ali ndi zaka zambiri mumakampani opanga ma semiconductor nthawi zambiri amakumana ndi mavuto otere. Chifukwa chake, kuti musankhe ndikugwiritsa ntchito bwino zophimba zotsutsana ndi okosijeni za graphite rotor, ndikofunikira choyamba kumvetsetsa njira zolephera za zophimbazo kenako ndikuwona momwe kampani yomwe ili ndi luso lokonza pamwamba pa zinthu ingasiyanitsire m'malo ofunikira.

I. N’chifukwa chiyani ma rotor a graphite sangachite popanda chophimba choletsa okosijeni?
Graphite yokha ndi "yochezeka" kwambiri ndi aluminiyamu yosungunuka:

• Kulemera kochepa komanso kopepuka, kuchepetsa katundu wotumizira;
• Kukana kutentha bwino, sikungathe kusweka chifukwa cha kutentha mobwerezabwereza;
• Kukonza kosavuta, zomwe zimathandiza kuti pakhale mapangidwe ovuta a rotor impeller omwe amathandiza kusakaniza madzi a aluminiyamu ndi kufalitsa thovu.

Komabe, ilinso ndi kufooka koopsa: idzasungunuka nthawi zonse ndikugwiritsidwa ntchito m'malo otentha kwambiri okhala ndi mpweya wochuluka.

Mu mikhalidwe yachizolowezi yosungunula aluminiyamu:

• Kutentha kwa aluminiyamu yosungunuka nthawi zambiri kumakhala pakati pa 720–780°C, ndipo zinthu zina zimakhala zokwera kwambiri;
• Gawo lina la rotor limaonekera mumlengalenga wa ng'anjo, komwe mpweya ndi zinthu zoyaka sizingapeweke;
• Chozunguliracho chimazungulira mofulumira kwambiri, nthawi zonse chikuwonetsa graphite yatsopano yotentha kwambiri mumlengalenga.

Popanda chophimba chothandiza chotsutsana ndi okosijeni, rotor idzawonetsa:

• Zigawo za pamwamba zikuwotchedwa pang'onopang'ono, ndi kuchepa kwakukulu koonekera pakatha milungu kapena masiku;
• Pamwamba pamakhala poyipa komanso pobowola, zomwe zimapangitsa kuti thovu lifalikire mosagwirizana komanso kuchepetsa mphamvu yotulutsa mpweya m'thupi;
• Ufa wosungunuka ndi zinyalala zimagwa, zomwe zimakhala magwero ophatikizidwa mu aluminiyamu yosungunuka.

Cholinga cha chophimba chotsutsana ndi okosijeni ndikuthandiza graphite kupirira "nkhondo yogwiritsidwa ntchito nthawi yayitali" iyi pansi pa kutentha kwambiri, mpweya wochuluka, komanso malo osungunuka a aluminiyamu ndi slag.
