Kusankha ndi Kupita patsogolo Kwaukadaulo kwa Zida Zowukira Zopangira Ma Coreless Induction Furnaces

Induction ng'anjo ndi chipangizo chomwe chimagwiritsa ntchito mfundo ya electromagnetic field induction kutembenuza mphamvu yamagetsi kukhala mphamvu ya kutentha kuti itenthe ndikusungunula chitsulo. Malinga ndi kapangidwe kake, amagawidwa m'magulu awiri: ng'anjo yoyambira komanso ng'anjo yopanda coreless.

Mng'anjo ya coreless induction ili ndi ubwino wogwiritsa ntchito bwino kwambiri, kupulumutsa mphamvu, kuwononga pang'ono, kusintha kosavuta kwa mawonekedwe, kuwongolera mosavuta mlengalenga, kutentha kwamphamvu, komanso kugwira ntchito kwapakatikati. ng'anjo yolowera imagawidwa kukhala: ng'anjo yamagetsi yamagetsi (mkati mwa 50Hz); ng'anjo yapakati pafupipafupi (50Hz-10000Hz) ndi ng'anjo yowotcha pafupipafupi (pamwamba pa 10000Hz). M'zaka zaposachedwapa, ndi chitukuko ndi kudalirika kusintha mkulu-mphamvu thyristor variable pafupipafupi magetsi, wapakatikati pafupipafupi ng'anjo pang'onopang'ono m'malo mphamvu pafupipafupi ng'anjo. Poyerekeza ndi ng'anjo yamagetsi yamagetsi, ng'anjo yapakatikati imakhala ndi kutentha kwambiri komanso mphamvu zamagetsi, nthawi yochepa yosungunuka, kugwiritsa ntchito mphamvu zochepa, komanso kukhazikitsa kosavuta. ubwino wa automation. Kuphatikiza apo, ng'anjo yolowera ikukula molunjika ku mphamvu yayikulu komanso mphamvu yayikulu, yomwe ili ndi zofunikira zapamwamba pazida zokanira.

Refractory lining ndi chinthu chofunikira chomwe chimatsimikizira kutuluka kwa ng'anjo yolowera, kuponyedwa kwabwino ndi chitetezo ndi kudalirika kwa kupanga ndi kugwira ntchito. Kuti tipeze chingwe chokanira chokhala ndi khalidwe labwino komanso moyo wautali wautumiki, choyamba tiyenera kumvetsetsa zikhalidwe zogwiritsira ntchito: (1) Makulidwe azitsulo zokanira ndizokwera kwambiri. Wopyapyala, kutentha kwa gradient ndi kwakukulu; (2) Kugwedezeka kwamagetsi kwachitsulo chosungunula mu ng'anjo kumayambitsa kukokoloka kwa makina otchinga; (3) Chingwe cha refractory chimazimitsidwa mobwerezabwereza ndikukhudzidwa ndi thermally.

Choncho, osankhidwa zipangizo refractory ayenera kukhala: mokwanira mkulu refractoriness ndi kufewetsa kutentha pansi katundu; kukhazikika kwamphamvu kwamafuta; palibe mankhwala amachitira ndi zitsulo ndi slag; wina mkulu kutentha makina mphamvu; kutchinjiriza bwino ndi kusungunula; kumanga kwabwino, kachulukidwe wodzaza kwambiri, sintering yosavuta, kukonza kosavuta; chuma chochuluka cha zopangira refractory, mitengo yotsika, etc. Kukula kwa ng'anjo yolowera kumagwirizana kwambiri ndi kupita patsogolo kwaukadaulo kwa zida zotsutsa. Kapangidwe ka ng'anjo yayikulu yamphamvu yama frequency crucible induction nthawi zambiri imayambira pakusankhidwa kwa zida zotsutsa komanso kuyesa koyerekeza kwa ng'anjo yamoto. Mulimonsemo, kusankha kwa ng'anjo yopangira ng'anjo kumachokera ku kugwiritsidwa ntchito ndi chuma cha ng'anjo. Pofuna kugwirizanitsa zolimba pazida zamagetsi, kucheperachepera kwa makulidwe azitsulo, kumakhala bwino popanda kukhudza moyo wautumiki.
