Momwe Mungasankhire Ng'anjo Yosungunuka M'makampani Odzikongoletsera

Anthu ambiri amakonda kuvala zodzikongoletsera zamtengo wapatali monga zibangili, mikanda, mphete, ndolo, ndi zina zotero. Zitsulo zazikulu zomwe zimagwiritsidwa ntchito pa zodzikongoletsera ndi golide ndi platinamu.

Gawo loyamba popanga zodzikongoletsera zamtengo wapatali ndi kusungunula chitsulo chamtengo wapatali kudzera ang'anjo yosungunuka.Pali mitundu yambiri ya ng'anjo zosungunuka pamsika.Tidzakumana ndi mavuto posankha ng'anjo yosungunuka.Ife sititero't kudziwa ng'anjo yosungunuka yomwe ili yoyenera kwambiri pazosowa zathu zosungunula zitsulo.

M'makampani opanga zodzikongoletsera, ndizofala kugwiritsa ntchito ng'anjo zoyezera kusungunula zitsulo.Ndiye ngati mukufuna kusankha ang'anjo yosungunuka, muyenera kulabadira mfundo zotsatirazi:

M'malo mwake, ng'anjo zosungunuka za induction zimagwiritsidwa ntchito kwambiri pama frequency apakatikati komanso ng'anjo zamagetsi zapamwamba.Kutentha kwakukulu kwa ng'anjo yapakatikati yosungunuka ndi 2600°C. Kutentha kwakukulu kwa ng'anjo yothamanga kwambiri ndi 1600°C. Ndiye ngati mukuyang'ana kugula chitofu cholowera mkati, zimatengera chitsulo chomwe mukufuna kusungunuka.

Malo osungunuka a golide ndi 1064°C, malo osungunuka a platinamu ndi 1768°C, ndipo malo osungunuka a siliva ndi 961°C. Choncho ngati musungunula golide ndi siliva, muyenera kugwiritsa ntchito ng'anjo yotentha kwambiri, osati ng'anjo yapakatikati.Ngati kutentha kusungunuka kuli kwakukulu, kumayambitsa kusintha kwazitsulo.Chitsulo chosungunuka chikhoza kuipitsidwa.

Mwa njira, posankha ng'anjo yosungunuka, tifunikanso kumvetsera mtundu wa crucible.Pali mitundu iwiri ya crucibles: graphite crucible ndi quartz crucible.Kutengera ndi kutentha kosungunuka, ma graphite crucibles amagwiritsidwa ntchito m'ng'anjo zapamwamba kwambiri.Ndipo quartz crucible ya ng'anjo yapakati pafupipafupi.Quartz imalimbana ndi kutentha kwambiri kuposa graphite.Tiyenera kuzindikira kuti siliva amatha kugwiritsidwa ntchito muzitsulo za graphite, osati muzitsulo za quartz.Chifukwa siliva amachitira ndi quartz ndipo amalepheretsa siliva kusungunuka kwathunthu, ndiye amamatira ku crucible ndikupangitsa kutayika kwakukulu.
