Say submerged arc furnace- ya tatawagen met ya electric arc furnace odino electric resistance furnace-et manunan uusaren parad reductive smelting na saray raw materials a singa say ores, carbonaceous reducing agents, tan fluxes. Saya so manunan kagawaan ed industriya parad panaggawa na ferroalloys (singa say ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, tan silicomanganese alloys) tan saray kemikal ya materyales a singa say calcium carbide.
Say hurnoan et mankikimey ya uusaren so carbonaceous o magnesia refractory lining tan self-baking electrodes. Mankikimey iya panamegley na tuloytuloy a proseso ya mangilalanor ed submerged-arc operation-ditan et iiyan iray electrode ed furnace charge-tan manguusar na parehon arc energy tan resistance heating (ya napapawala legan ya onlalabas so kuryente ed charge) pian natunaw so metal; say panagkarga et tuloytuloy ya gagawaen, bangta say panag-tap ed tinunaw a metal tan slag et nagagawa ed panapanaon. Say transformer ya manseserbi ed hurnoan et mankikimey ed silong na tuloytuloy tan malet ya karga tan walaan na abeban impedance voltage, dakel a voltage regulation steps ya walaan na melag iran increments, tan atagey ya overload capacity. Sarayan transformer et walay duaran klase: on-load voltage regulation tan off-circuit (no-excitation) voltage regulation. Kaslakan, mangiiter ira na pirmin power output ed gapoan na boltahe tan pirmin kuryente ed ontumbok iran steps.
