Four arc submergé ñu ngi ko xaaj ñaari xeetu electrode: four yi am electrode yuñ raññe ci ñatti kaar (muy four yu wër ak ñatti kaar) ak yi am electrode yuñ raññe ci liiñ bu jub (muy four yu rectangle ak elliptique). Ay misaal yuñ gëna xam ñooy four yu am wërngël (lu melni four ferroalloy) ak four yu am rektangul (lu melni four yuy fonder matt).
Buñu ko méngale ak four rectangle yi, four circulaire yi dañu am màndarga yii:
1) Ñatti electrode yi dañu leen raññe ci benn triangle bu tolloo, loolu moo jur sargu ñatti fase yu ekilibre (resistance buy liggéey) ak séddaleb doole;
2) Zone bi tàngoor wi yéeg dafay gëna bari, loolu mooy tax barabu core furnace bi (diggante ñatti electrode yi) mëna yegg ci tàngoor yu gëna kawe;
3) Miir bu tàngoor -disipation surface surface ci unité croix-section piscine melten bi moo gëna ndaw; loolu du wàññi tàngoor wi kese, waaye dafay tax kuuraŋ bi di gëna gudd fan;
4) Yaramam four bi mën nañu ko wëlbati ci anam wu mekanik ngir mëna dem bu baax ak dem bi ak dikk bi ci biir four bi.
Buñu ko méngale ak four yu wërngël yi, four yu rectangle yi dañu am màndarga yii:
1) Four bi dafa yomb, te xeetu aparey electromecanique yiy jàppale (transformatër yi, masin yiy sarse ak yiy desarse) ñoo gëna yomba;
2) Mën nañu tëye 6 electrode, loolu mooy yaatal zone smelting bi;
3) Electrodes yi dañuy wàññi lu bari ci dem bi ak dikk bi ci macceer, suko defee ñu mëna bàyyi gaz yiy génn ci smelting bi;
4) Differens tamperatiir yi ci biir piscine molten yi ñoo gëna ndaw, moo tax tàngoor wi gëna néew.
Four yu am ñatti wërsëg lañuy jëfandikoo ngir defar ay mbir yu melni fonde matt, defar carbure de calcium, ak defar ferromanganèse. Four ferroalloy yu bari dañu wër; four yu wërngël yi dañu leen di jëfandikoo itam ci liggéeyum fondeur bu amul fer, ci misaal, ci fondement mineraal oxide de nickel ak cobalt.
Four arc submergé benn xeetu four la buy fonder; dimension yi gëna am solo ci yaramu four bi mooy piscine molten-espesialeman guddaayam, yaatuwaayam (wala diametre), ak xóotaayu. Ginaaw four yooyu dañuy njëkka jëfandikoo kuuraŋ ngir tàngal, ci theorie piscine biy seey mooy zone bi gëna am solo ngir soppi energie electrik ci tàngoor; Kon, dimension piscine molten yi dañuy gëna bari diametre electrode bi.
Four yu am ñatti wërsëg dañuy faral di am kaw four buy dox ci anam wu tëju; seen dimension bu njëkk mooy guddaay bi, yaatuwaayam, ak xóotaayu piscine biy seey, ak itam diggante -ba-diggu electrode yi ak kawewaayu néegu four bi.
