Njira yosungunula zitsulo ndi zitsulo zosasunthika mu ng’anjo yosungunuka

Before the induction furnace is charged, the residue in the furnace should be removed, and the damage of the furnace lining should be checked. The severely damaged parts have become black due to rapid cooling and should be repaired. The grain size of the repairing material should be slightly smaller than that of the knotted material, and the binder used should be slightly more. Large-scale furnaces that are severely damaged can be hoisted into the furnace iron mold to fill in knots.

Popeza kutentha kwa ng’anjo yopangira ng’anjo kumatsika mofulumira pambuyo pogogoda, iyenera kulipidwa mwamsanga ndipo iyenera kudzazidwa ndi migolo momwe mungathere. Pofuna kufulumizitsa kusungunuka, zinthuzo ziyenera kugawidwa moyenera malinga ndi kugawidwa kwa kutentha mu ng’anjo. Kugawidwa kwa kutentha mu ng’anjo yolowetsamo kukuwonetsedwa mu Chithunzi 4-25. Chifukwa cha khungu lamakono, malo ozungulira a chigawo chakuthupi (zone I) pafupi ndi khoma la volute ndi malo otentha kwambiri.

Pansi ndi pakati (I, TT zone) zimakhala ndi kutentha kochepa, komwe kumakhala malo otentha kwambiri, ndipo kumtunda (IV zone) kumakhala ndi kutentha kwa maginito komanso kutaya kwakukulu kwa kutentha, komwe kumakhala malo otsika kwambiri.

Kuti mupange slag pasadakhale, 1% ya zinthu za slag ndi kulemera kwake zitha kuwonjezeredwa pansi pa ng’anjo musanalipire, laimu ndi fluorite zimawonjezeredwa kung’anjo yamchere, ndipo galasi la galasi limawonjezeredwa kung’anjo ya asidi.

Kumayambiriro kwa kusungunuka, chifukwa inductance ndi capacitance pa mzere sizingafanane mofulumira komanso moyenera, panopa ndi yosakhazikika, kotero ikhoza kuperekedwa ndi mphamvu yochepa mu nthawi yochepa. Zapano zikakhazikika, ziyenera kusinthidwa kukhala zonyamula katundu. Panthawi yosungunuka, capacitor iyenera kusinthidwa nthawi zonse kuti zipangizo zamagetsi zikhale ndi mphamvu zambiri. Mlanduwo utatha kusungunuka, chitsulo chosungunuka chimatenthedwa mpaka kufika pamlingo wina, ndiyeno mphamvu yolowera imachepetsedwa malinga ndi zofunikira za smelting.

Nthawi yoyenera yosungunuka iyenera kuyendetsedwa. Ngati nthawi yosungunuka ndi yochepa kwambiri, izi zimabweretsa zovuta pakusankha ma voliyumu ndi capacitance. Ngati italika kwambiri, idzawonjezera kutaya kwa kutentha kosathandiza. Nsalu zosayenera kapena dzimbiri lambiri mu ng’anjo ya ng’anjo zingayambitse “kutsekereza” chodabwitsa, chomwe chiyenera kuchitidwa panthawi yake. “Bridge” imalepheretsa zinthu zosasungunuka zomwe zili kumtunda kuti zisagwere muzitsulo zosungunuka, kusuntha yuhua, ndipo kutenthedwa pansi kwa chitsulo chosungunuka kungawononge mosavuta ng’anjo ya ng’anjo, komanso kumapangitsa kuti chitsulo chosungunula chitenge zambiri. wa gasi.

Chifukwa cha kugwedezeka kwamagetsi, pakati pa zitsulo zosungunula zimaphulika, ndipo slag nthawi zambiri imathamangira m’mphepete mwa crucible ndikumamatira ku khoma la ng’anjo. Choncho, slag iyenera kuwonjezeredwa mosalekeza malinga ndi momwe ng’anjo imapangidwira panthawi yosungunuka.
