Preheating Guidelines
- Ho beoa haufi le Sebōpi sa Oli bakeng sa Preheating: Beha crucible haufi le sebōpi sa oli bakeng sa lihora tsa 4-5 pele o sebelisoa pele. Ts'ebetso ena ea ho futhumatsa pele e thusa ho fokotsa mongobo holim'a metsi, ho matlafatsa botsitso ba crucible.
- Ho chesoa ha Mashala kapa Patsi: Beha mashala kapa patsi ka har'a crucible 'me u chese lihora tse ka bang nne. Mohato ona o thusa ho tlosa mongobo 'me o ntlafatsa ho hanyetsa mocheso oa crucible.
- Ramp-up ea Mocheso oa Sebōpi: Nakong ea mohato oa pele oa ho futhumatsa, butle-butle eketsa mocheso ka sebōping ho latela mehato e latelang ea mocheso ho netefatsa botsitso le bophelo bo bolelele ba crucible:
- 0°C ho isa ho 200°C: Ho futhumala butle ka lihora tse 4 (sebopi sa oli) / motlakase
- 0°C ho isa ho 300°C: Ho futhumala butle ka hora e le 1 (motlakase)
- 200°C ho isa ho 300°C: Ho futhumala butle ka lihora tse 4 (sebōpi)
- 300°C ho isa ho 800°C: Ho futhumala butle ka lihora tse 4 (sebōpi)
- 300°C ho isa ho 400°C: Ho futhumala butle ka lihora tse 4
- 400 ° C ho 600 ° C: Ho futhumatsa ka potlako, ho boloka lihora tse peli
- Post Shutdown Reheating: Kamora ho koala, nako ea ho futhumatsa oli le libopi tsa motlakase ke e latelang:
- 0°C ho isa ho 300°C: Ho futhumala butle bakeng sa hora e le 1
- 300°C ho isa ho 600°C: Ho futhumala butle ka lihora tse 4
- Ka holimo ho 600°C: Ho futhumatsa ka potlako ho fihlela mocheso o hlokahalang
Litaelo tsa ho koala
- Bakeng sa libono tsa motlakase, ho eletsoa ho boloka ho kenngoa ha mocheso o tsoelang pele ha o sa sebetse, ka mocheso o behiloeng ho pota 600 ° C ho thibela ho pholile ka potlako. Haeba ho sa khonehe, ntša lisebelisoa ho crucible ho fokotsa lintho tse setseng.
- Bakeng sa libopi tsa oli, kamora ho koala, etsa bonnete ba ho ntša lisebelisoa ka hohle kamoo ho ka khonehang. Koala sekoahelo sa sebōpi le likou tsa moea ho boloka mocheso o setseng le ho thibela mongobo o ka hare.
Ka ho latela litataiso tsena tsa mahlale tsa preheating le litemoso tsa ho koala, ts'ebetso e nepahetseng ea li-graphite crucibles tlhahiso ea indasteri e ka netefatsoa, ka nako e ts'oanang e ntlafatsa katleho ea tlhahiso le ho sireletsa polokeho ea indasteri. Ha re kopaneleng boitlamo ba boiqapelo ba theknoloji ho tsamaisa tsoelopele ea indasteri.
