Submerged arc furnace hi electrode inrem dan azirin chi hnih ah then a ni a, chungte chu electrode triangle-a dah (circular leh triangular furnace te pawh tel) leh electrode line dik taka dah (rectangular leh elliptical furnace te pawh tel) te an ni. Entirna tlangpui chu circular furnace (ferroalloy furnace ang chi) leh rectangular furnace (matte smelting furnace ang chi) te hi a ni.
Rectangular furnace nena khaikhin chuan circular furnace hian a hnuaia mi ang hian a nei a:
1) Electrode pathumte hi equilateral triangle-ah an dah a, chu chuan three-phase load (working resistance) leh power distribution chu a inthlau hle a
2) High-temperature zone chu a concentrate deuh a, furnace core area (electrode pathum inkar) chu temperature sang zawk a thleng thei a
3) Furnace wall heat-dissipation surface area chu unit cross-section khata molten pool-a a tlem zawk a; hei hian heat loss a tihtlem mai bakah power-off period rei zawk a siam thei bawk;
4) Furnace chhunga thil awmte chu a kal tluang thei ang bera kal theih nan leh furnace body chu mechanically rotate theih a ni.
Circular furnace nena khaikhin chuan rectangular furnace hian a hnuaia mi ang hian a nei a:
1) Furnace siam dan hi a awlsam hle a, auxiliary electromechanical equipment (transformer, charging leh disharging machinery) te layout pawh a awlsam zawk a
2) Electrode paruk an dah thei a, chu chuan smelting zone a tizau a;
3) Electrode hian thil kal danah khapna tlem zawk a siam a, chu chuan smelting-a gas lo chhuakte chu a chhuah awlsam phah a;
4) Melten pool huam chhunga temperature danglamna a tlem zawk avangin localized overheating a awm lo.
Rectangular furnace hi matte smelting, calcium carbide siamna, ferromanganese siamna atan te hman a ni. Ferroalloy furnace tam zawk hi chu circular an ni a; circular furnace hi non-ferrous smelting industry-ah pawh hman a ni a, entirnan, nickel oxide ore leh cobalt slag smelting-ah te pawh hman a ni.
Submerged arc furnace hi smelting furnace chi khat a ni a; furnace taksa dimension pawimawh ber chu molten pool-a bik takin a sei zawng, a zau zawng (or diameter), leh a thuk zawng te hi a ni. Heng furnace te hian lumna atan electric an rinchhan ber avangin, molten pool hi theoretically chuan electrical energy chu heat-a chantirna tur effective zone angin a thawk a chuvangin, molten pool dimension te hi a tlangpuiin electrode diameter multiples a ni.
Rectangular furnace-ah hian furnace roof dah a ni tlangpui a, enclosed unit angin an thawk a; an dimension bulpui ber chu molten pool sei zawng, zau zawng leh thuk zawng bakah electrode-te center-to-center inkar leh furnace chamber san zawng te a ni.
