Ol 'submerged arc furnaces' i gat tupela kain 'electrode' i stap long en: ol dispela we i gat ol 'electrode' i stap long wanpela 'triangle' (wantaim ol 'circular' na 'triangular' 'furnace') na ol dispela we i gat ol 'electrode' i stap long wanpela stretpela lain (olsem ol 'rectangular' na 'elliptical' 'furnace'). Ol eksampel em ol 'circular furnace' (olsem 'ferroalloy furnaces') na 'rectangular furnaces' (olsem 'matte smelting furnaces').
Taim yumi skelim wantaim ol 'rectangular furnace', ol 'circular furnace' i gat ol dispela samting:
1) Ol tripela 'electrodes' i stap long wanpela 'equilateral triangle', na dispela i mekim na ol i gat 'balanced three-phase loads (working resistance) na pawa distribusen;
2) Hai-tempereja zon i stap longpela taim, na dispela i larim 'furnace core area' (namel long tripela 'electrodes') long kisim bikpela tempereja;
3) 'Furnace wall heat-dissipation surface area long wanwan yunit kros-seksen bilong 'molten pool' i liklik; dispela i no daunim lus bilong hat tasol tu i larim pawa i stap longpela taim;
4) Ol i ken tanim bodi bilong 'furnace' long rot bilong masin long mekim ol samting i ron gut na muv gut insait long 'furnace'.
Taim yumi skelim wantaim ol 'circular furnace', ol 'rectangular furnace' i gat ol dispela samting:
1) Straksa bilong 'furnace' em i isi tru, na 'layout' bilong ol 'auxiliary electromechanical equipment' (ol 'transformer', ol masin bilong sasim na rausim ol masin) i gutpela moa;
2) Ol i ken holim 6-pela 'electrode', na dispela i mekim 'smelting zone' i go bikpela;
3) Ol 'electrodes' i no save putim planti tambu long muvmen bilong ol samting, na dispela i mekim isi long rausim ol ges we i kamap taim ol i wokim smelting;
4) Ol senis long tempereja long olgeta hap bilong 'molten pool' i liklik, na dispela i mekim na 'localized overheating' i no inap kamap.
Ol i save yusim ol 'rectangular furnace' long ol wok olsem 'matte smelting', 'calcium carbide' prodaksen, na 'ferromanganese' prodaksen. Planti 'ferroalloy' oven i save raunpela; ol i save yusim ol 'circular furnace' tu long ol non-ferrous smelting indastri, olsem, long smelting bilong nikel oksait ore na kobalt slag.
'Summerged arc furnace' em i wanpela kain 'smelting furnace'; ol bikpela samting bilong bodi bilong 'furnace' em ol 'molten pool'-speseli longpela, bikpela (o diamita), na dip bilong en. Long wanem, ol dispela 'furnace' i save yusim pawa bilong hatim, 'molten pool' i save stap olsem gutpela hap bilong senisim pawa pawa i go long hat; olsem na, ol sais bilong 'molten pool' i save kamap planti taim long 'electrode diameter'.
Ol 'rectangular furnace' i save gat rup bilong 'furnace' na ol i save wok olsem ol 'enclosed units'; ol bikpela mak bilong ol i gat longpela, bikpela, na dip bilong 'molten pool', na tu, namel-i go long-spela namel bilong ol 'electrodes' na antap bilong 'furnace chamber'.
