Mafuro akadzika arc akaiswa muzvikamu negadziriro ye electrode mumhando mbiri: idzo dzine maelectrodes akarongwa mugonyo (kusanganisira denderedzwa netrianngular furnaces) uye ayo ane maelectrodes akarongwa mumutsara wakatwasuka (kusanganisira rectangular uye elliptical furnaces). Mienzaniso yakajairika inosanganisira mavhiri akatenderedzwa (akadai semafuta eferroalloy) uye makombi ane rectangular (senge matte smelting furnaces).
Kuenzaniswa nevira rectangular, mavhiri akatenderera anoratidza zvinotevera maitiro:
1) Maelectrode matatu akarongwa mugonyonhatu yakaenzana, zvichiita kuti pave nepakati pematatu-mitoro yechikamu (kushanda kuramba) uye kugovera magetsi;
2) Iyo yakakwirira-nzvimbo yetembiricha yakadzikama, zvichibvumira nzvimbo yepakati pechoto (pakati pemaelectrode matatu) kuti isvike kupisa kwakanyanya;
3) Kupisa kwemudhuri wechoto{1}}nzvimbo yekurasira pachikamu chimwe nechimwe -chikamu chedziva rakanyungudutswa idiki; izvi hazvingodzikisi kurasikirwa nekupisa chete asiwo zvinobvumira simba rakareba-kudzima nguva;
4) Muviri wechoto unogona kutenderedzwa nemichina kuti ive nechokwadi chekuyerera uye kufamba kwezvinhu mukati mechoto.
Kuenzaniswa nevira denderedzwa, makombi ane rectangular ane anotevera maitiro:
1) Chimiro chechoto chiri nyore, uye dhizaini yeanobatsira electromechanical midziyo (transformers, kuchaja uye kuburitsa muchina) iri nyore;
2) Vanogona kugadzirisa ma electrode matanhatu, nekudaro vachiwedzera nzvimbo yekunyungudutsa;
3) Electrodes inoisa zvirambidzo zvishoma pakufamba kwezvinhu, zvichiita kuti zvive nyore kuburitsa magasi anogadzirwa panguva yekunyungudutswa;
4) Misiyano yetembiricha mhiri kwedziva rakanyungudutswa idiki, zvichiita kuti kupisa kwenzvimbo kuite kushoma.
Rectangular furnaces anoshandiswa kuita senge matte smelting, calcium carbide kugadzirwa, uye ferromanganese kugadzirwa. Mafuro akawanda eferroalloy ane denderedzwa; circular furnaces anoshandiswawo mune isiri-ferrous smelting industry, semuenzaniso, mukunyungudutsa nickel oxide ore necobalt slag.
The undermerged arc furnace imhando ye smelting furnace; iwo akanyanya kuomesesa emuviri wechoto ndeaya edziva rakanyungudutswa{0}kunyanya kureba, kufara (kana dhayamita), nekudzika. Sezvo mavira aya vanotsamira zvikurukuru pamagetsi pakudziisa, dziva rakanyungudutswa redzidziso rinoshanda senzvimbo inobudirira yekushandurwa kwesimba remagetsi mukupisa; nokudaro, kukura kwedziva rakanyungudutswa kazhinji kacho kuwanda kwedhayamita ye electrode.
Rectangular furnaces inowanzogadzirirwa nedenga rechoto uye inoshanda sezvikamu zvakavharwa; hukuru hwavo hunosanganisira kureba, kufara, nekudzika kwedziva rakanyungudutswa, pamwe nepakati-ku-pakati pepakati pema electrode uye kureba kwekamuri rechoto.
