Saray submerged arc furnaces (SAFs) et manguuman ed enerhiya na kuryente ed arc heat tan resistance heat panamegley na saray electrode, ya direktan mamapainit ed ore odino metal ya materyales pian naabot so atagey a temperatura na panagtunaw. Sayan artikulo et mangibiig ed saray kabiangan na istruktura, lohika na panagpasimbalo na enerhiya, tan saray kaslakan ya aplikasyon ed industriya.
Saray Manunan Kabiangan na Istruktura
Say manunan istruktura na SAF so mandetermina ed inkaepektibo tan inkapekder na enerhiya to, ya tugyopen na taloran manunan yunit:
- Electrode System: Kaslakan et manguusar na graphite electrodes pian makaloob so kuryente ed silir na hurnoan tan makagawa na electric arc.
- Istruktura na Hurnoan: Walay ag-onsisinag ya lining tan bakal ya shell; kaukolan ya makaanos ed temperatura ya onlampas ed 1600 degree.
- Cooling System: Protektaan to ray importantin kabiangan-singa saray electrode holders tan say furnace shell-panamegley na danum-cooling circuits.
- Design Key: Say ratio na kapal na lining ed diametro na electrode et direktan mangaapekta ed inkapara na thermal field.
Proseso na Panguman na Enerhiya
Say energy transfer chain, manlapud suplay na kuryente anggad panagtunaw, et walaan na taloran yugtan:
- Saray transformer et manguuman ed atagey-boltahe na kuryente ed abeban-boltahe, atagey-kuryente ya matukoy parad arc stability.
- Saray control system et mangi-adjust na posisyon na electrode pian napansiansia so sankaabigan ya arc length ed baetan na saray electrode tan saray raw materials.
- Say resistensya na petang et napapawala legan ya onlalabas so kuryente ed karga na hurnoan; saya so mankasakey ed petang na arc pian manporma na nankakasakey a lapuan na petang.
- Saray Manunan Parametro: Say segundaryon boltahe tan say densidad na kuryente na electrode so mandetermina ed gradient na temperatura na tinunaw a pool.
Kaslakan ya Aplikasyon ed Industriya
Say direktan panagpainit na kuryente to so manggagawa ed satan ya nakaukolan ed duaran klase na senaryo:
- Metal Smelting: Reduction reactions parad saray refractory metals a singa say ferroalloys tan silicomanganese alloys.
- Panagproseso na Mineral: Saray kemikal a reaksion ed atagey a temperatura a singa say defluorination na phosphate rock odino say panagtunaw na titanium slag.
- No ikompara ed saray electric arc furnace (EAFs), saray SAFs et mas matukoy parad panagproseso na saray pulbos ya hilaw a materyales tan saray proseso na panag-asikaso ya mankaukolan na andukey a panag-ala na petang.
Saray Manunan Sistema na Tulong
Say tuloytuloy tan malet ya operasyon et mandedependi ed koordinasyon na taloran auxiliary units:
- Electrode Regulator: Dinamikon manbabayad ed konsumo na electrode pian napansiansia so arc stability.
- Temperature Monitoring System: Kaiba iray infrared pyrometers tan in-furnace cameras pian nabantayan so kipapasen na tinunaw a pool.
- Dust Removal Unit: Manproseso na atagey a temperatura na flue gas ya napapawala legan na panagtunaw.
- Safety Note: Saray sukat na kapal na dingding na hurnoan et importante pian naprebentaan so aksidente ed pakabuyak na hurnoan.
O&M Consumables System
Taloran kategorya na saray nausar et mankaukolan na manunan panangasikaso legan na inagew-agew a produksyon:
- Saray materyales ed pangapiger na lining na hurnoan: Magnesia- odino carbon-based refractories ya uusaren ed pangapiger ed saray naderal ya dingding na hurnoan.
- Slag conditioning agents: Uusaren pian na-adjust so slag fluidity tan naprotektaan so lining na hurnoan.
- Electrode paste: Conductive material ya kaukolan so panapanaon ya pan-replenish parad tuloytuloy ya self-baking electrodes.
- Mas mabiskeg ya paraan: Manggawa na kurba na korelasyon ed baetan na temperatura na panag-sinter na electrode paste tan say current load.
