Ukusebenzisa i-Gold Assaying Crucible

Indlela yokuhlola umlilo yegolide iwukunquma inani lezinsimbi eziyigugu ngobuningi ngokuncibilikisa insimbi nemikhiqizo yensimbi ene-flux. Ekuhlaziyweni kokulamula kokuqukethwe kwegolide nesiliva, indlela yokuhlola umlilo ivame ukusetshenziswa njengoba inokunemba okuphezulu kanye nokunemba kwemiphumela yokunquma. ,

I-fire assay crucible inokumelana okuhle kwezinga lokushisa, ukusetshenziswa kwesikhathi eside ku-1300 ℃, isikhathi esifushane ngu-1550 ℃, nokumelana okuhle nokupholisa okusheshayo nokushisa, akulula ukuqhuma. Khona-ke sidinga ukunaka amaphuzu alandelayo lapho sisebenzisa i-test crucible.

1. isisindo sesampula

Ngokwezidingo eziyinkimbinkimbi zamasampuli angenayo, zikale bese uzibhala izinombolo ngokulandelana kwazo. Faka i-crucible yobumba nezinye izithako eziyisisekelo ezikhona kuwo, bese wengeza isitashi esincibilikayo esidingekayo (isisindo esiyi-quasi) kanye ne-lead oxide ngokwezithako ngokuya ngezigaba zesampula kanye nezidingo, bese usifaka ku-hood yomusi ukuze ugqugquzele ngokugcwele. .

2. lokushisa ukufudumala ke wafaka esithandweni

Lapho izinga lokushisa lomlilo likhuphukela ku-750-900 ℃, vala amandla ekhabhinethi (ukugwema ukulimaza i-silicon carbon rod), bese ufaka i-crucible yobumba equkethe isampula esithandweni ngokwenombolo. vala isithando somlilo kuqala, bese ufaka amandla kagesi; Ngemva kokungena esithandweni somlilo, vala umnyango wesithando somlilo, vula iswishi yamandla, ulungise izinga lokushisa libe ku-750 ℃, bese ulinda imizuzu engu-30 lapho izinga lokushisa likhuphuka lifinyelele ku-750 ℃; lungisa izinga lokushisa libe ngu-1100℃, bese ulinda imizuzu engu-20 lapho izinga lokushisa likhuphuka libe ngu-1100℃.Qhubeka nokushisa imizuzu engu-10.

3. Phuma

Vala isithando somlilo sikagesi, thatha isampula encibilikayo eshisayo esithandweni ngokwenombolo, uthele ku-crucible yensimbi bese uvumela ama-cooltes.

4. Ukudiliza

Khipha i-slag epholile ku-iron crucible, ukhiphe i-slag ekuholeni ngaphakathi ngokwenombolo bese uyishaya ibe isikwele ukuze ama-tweezers athathe.

Kala ibhande bese ubala ngenombolo.
