Kuzamura umutekano winganda no gukora neza hamwe no gukoresha neza Graphite Crucibles

Mu myaka yashize, ikoreshwa ryaibishushanyo mboneramu byuma byo mu nganda gushonga no gutara byagiye byiyongera, bitewe nubushakashatsi bwabo bushingiye kubutaka butanga ubushyuhe budasanzwe bwo hejuru. Nyamara, mu mikoreshereze ifatika, benshi birengagiza inzira yingenzi yo gushyushya umusaraba mushya wa grafite, biganisha ku ngaruka zishobora guhungabanya umutekano w’umuntu n’umutungo kubera kuvunika gukomeye. Kugirango twongere inyungu zumusaraba wa grafite, turatanga ibyifuzo bishingiye kubumenyi kugirango bikoreshwe neza, byemeze umusaruro mwiza ndetse n’umutekano mu nganda.

Ibiranga Graphite Crucibles

Graphite crucibles igira uruhare runini mugushonga ibyuma no gutara bitewe nubushyuhe budasanzwe bwumuriro. Mugihe zigaragaza neza ubushyuhe bwumuriro ugereranije na kariside ya silicon karbide, zirashobora kwanduzwa na okiside kandi zifite umuvuduko mwinshi wo kumeneka. Kugira ngo ibyo bibazo bikemuke, ni ngombwa gukoresha uburyo bwa siyansi yumvikana neza.

Amabwiriza yo kubanza

1. Gushyira hafi y'itanura rya peteroli kugirango ushushe: Shyira ingirakamaro hafi y'itanura rya peteroli amasaha 4-5 mbere yo kuyakoresha bwa mbere. Ubu buryo bwo gushyushya bufasha hejuru yubutaka, byongera imbaraga zingenzi.
2. Gutwika Amakara cyangwa Igiti: Shira amakara cyangwa ibiti imbere yingenzi hanyuma utwike amasaha agera kuri ane. Iyi ntambwe ifasha mukwangiza no kunoza ubushyuhe bwimbaraga.
3. Ubushyuhe bwa Furnace Ramp-up: Mugihe cyambere cyo gushyushya, gahoro gahoro wongere ubushyuhe mumatara ukurikije ibyiciro byubushyuhe bukurikira kugirango habeho ituze no kuramba byingenzi:
   • 0 ° C kugeza 200 ° C: Gushyushya buhoro amasaha 4 (itanura ryamavuta) / amashanyarazi
   • 0 ° C kugeza 300 ° C: Gushyushya gahoro kumasaha 1 (amashanyarazi)
   • 200 ° C kugeza 300 ° C: Gushyushya buhoro amasaha 4 (itanura)
   • 300 ° C kugeza 800 ° C: Gushyushya buhoro amasaha 4 (itanura)
   • 300 ° C kugeza 400 ° C: Gushyushya buhoro amasaha 4
   • 400 ° C kugeza kuri 600 ° C: Gushyushya byihuse, kubungabunga amasaha 2
4. Ubushyuhe bwa Post Shutdown: Nyuma yo kuzimya, igihe cyo gushyushya amavuta nitanura ryamashanyarazi nibi bikurikira:
   • 0 ° C kugeza 300 ° C: Gushyushya gahoro kumasaha 1
   • 300 ° C kugeza kuri 600 ° C: Gushyushya buhoro amasaha 4
   • Hejuru ya 600 ° C: Gushyushya byihuse ubushyuhe bukenewe

Amabwiriza yo kuzimya

• Ku itanura ry'amashanyarazi, birasabwa gukomeza guhora ukinguye mugihe udafite akazi, hamwe n'ubushyuhe bwashyizwe kuri 600 ° C kugirango wirinde gukonja vuba. Niba insulation idashoboka, kura ibikoresho mubikomeye kugirango ugabanye ibintu bisigaye.
• Ku itanura ryamavuta, nyuma yo kuzimya, menya neza ko wasibye ibikoresho bishoboka. Funga umupfundikizo w'itanura hamwe n'ibyambu bihumeka kugirango ubungabunge ubushyuhe busigaye kandi wirinde ubushuhe bukomeye.

Mu gukurikiza aya mabwiriza ashingiye ku bumenyi bushingiye ku buhanga no kwirinda ingamba zo guhagarika, imikorere myiza y’imisaraba ya grafite mu musaruro w’inganda irashobora gukorwa, icyarimwe ikazamura umusaruro kandi ikarinda umutekano w’inganda. Reka twese hamwe twiyemeze guhanga udushya mu iterambere mu nganda.
