Ukusebenzisa i-Gold Assaying Crucible

Indlela yokuvavanya umlilo yegolide imisela umxholo wesinyithi esixabisekileyo ngokobungakanani ngokunyibilikisa ore kunye neemveliso zetsimbi kunye ne-flux. ,

I-crucible assay crucible inokumelana nokushisa okulungileyo, ukusetyenziswa kwexesha elide kwi-1300 ℃, ixesha elifutshane le-1550 ℃, kunye nokuchasana kakuhle nokupholisa ngokukhawuleza kunye nokushisa, akukho lula ukuqhuma. Emva koko kufuneka sinikele ingqalelo kula manqaku alandelayo xa usebenzisa i-crucible test.

1. isampuli yokulinganisa

Ngokweemfuno ezintsonkothileyo zeesampulu ezingenayo, zilinganise kwaye uzifake iinombolo ngokulandelelana kwazo. Yongeza i-crucible yodongwe kunye nezithako ezisisiseko ezikhoyo kuyo, uze udibanise isitashi esinyibilikayo (quasi-weight) kunye ne-oxide ekhokelayo ngokwezithako ngokuhlelwa kwesampulu kunye neemfuno, uze uyibeke kwi-hood yomsi ukuze uvuselele ngokupheleleyo. .

2. ukufudumala kobushushu ngoko kufakwe eziko

Xa iqondo lobushushu eziko liphakama ukuya kuma-750-900℃, cima unikezelo lwamandla ekhabhathini (ukuphepha ukonakalisa i-silicon carbon rod), kwaye ubeke i-crucible yodongwe equlethe isampuli kwiziko ngokwenani. eziko, cima iswitshi kuqala, emva koko unikezelo lwamandla; Emva kokungena eziko, vala ucango lwesithando somlilo, vula iswitshi yamandla, lungisa ubushushu ukuya kuma-750 ℃, kwaye ulinde imizuzu engama-30 xa ubushushu buphakama ukuya kuma-750 ℃; lungisa iqondo lokushisa ukuya kwi-1100 ℃, kwaye ulinde imizuzu engama-20 xa ubushushu buphakama ukuya kwi-1100 ℃.Qhubeka ukutshisa imizuzu eyi-10.

3. Phuma

Cima isithando sombane, thatha isampuli eshushu enyibilikayo kwisithando somlilo ngokwenani, uthele kwi-crucible yentsimbi kwaye uvumele ukuba ipholile.

4. Ukuthoba

Thatha i-slag epholileyo kwi-iron crucible, ukhuphe i-slag kwi-lead ngaphakathi ngokwenani kwaye uyibethe kwisikwere ukuze i-tweezers ithathe.

Viyisha iqhosha kwaye ubale ngenani.
