Kusagwira ntchito mokhazikika kwa ng’anjo yosungunuka kungayambitse ngozi zazikulu
Kusagwira ntchito mokhazikika kwa ng’anjo yosungunuka kungayambitse ngozi zazikulu
The chowotcha kutentha palokha ndi mgwirizano wa machitidwe atatu a magetsi, madzi, ndi mafuta. Kuchita zinthu mosasamala nthawi zambiri kumabweretsa ngozi zoopsa. Zotsatirazi ndizoletsedwa kwambiri:
(1) Malipiro osayenerera ndi kusinthasintha kumawonjezedwa ku ng’anjo;
(2) Lumikizani chitsulo chosungunula chokhala ndi kansalu kolakwika kapena konyowa;
(3) Chophimba cha ng’anjo chikupezeka kuti chawonongeka kwambiri, ndipo kusungunuka kumapitirirabe;
(4) Kugwedezeka kwamphamvu kwamagetsi pazitsulo za ng’anjo;
(5) Ng’anjoyo imayenda popanda madzi ozizira;
(6) Chitsulo chosungunuka kapena thupi la ng’anjo limagwira ntchito popanda maziko;
(7) Thamangani pansi pa chitetezo chokwanira chachitetezo chamagetsi;
(8) Ngati ng’anjoyo ilibe mphamvu, perekani ndalama, ramming charge, sampuli, ndi kuwonjezera.
Aloyi yamagulu, kuyeza kutentha, kuchotsa slag, etc. Ngati ntchito zina zomwe tatchulazi ziyenera kuchitidwa ndi magetsi, njira zotetezera ziyenera kuchitidwa, monga kuvala nsapato zotetezera ndi kuvala magolovesi a asibesitosi.
Ntchito yokonza ng’anjo ndi zida zake zothandizira magetsi ziyenera kuchitika pamene mphamvu ikulephera.
Pamene ng’anjo ikugwira ntchito, m’pofunika kuyang’anitsitsa kutentha kwachitsulo, chizindikiro cha ngozi, kutentha kwa madzi ozizira komanso kuthamanga kwa madzi panthawi ya smelting. Mphamvu ya ng’anjo ya ng’anjo imasinthidwa kukhala pamwamba pa 0.9, ndipo gawo lachitatu kapena lachisanu ndi chimodzi lamakono ndiloyenera. Kutentha kwamadzi kutulutsa kwa sensor, etc. sikudutsa mtengo wapamwamba womwe umafotokozedwa pamapangidwewo. Malire apansi a kutentha kwa madzi ozizira nthawi zambiri amatsimikiziridwa ngati palibe condensation yomwe imapezeka pakhoma lakunja la sensa, ndiko kuti, kutentha kwa madzi ozizira kumakhala kokwera pang’ono kuposa kutentha kwa mpweya wozungulira. Ngati izi sizikukwaniritsidwa, condensation idzachitika pamwamba pa sensa, ndipo kuthekera kwa kuwonongeka kwa sensa kudzawonjezeka kwambiri.
Pambuyo popanga mankhwala ndi kutentha kwa chitsulo chosungunula chikakwaniritsa zofunikira, mphamvu iyenera kudulidwa ndipo chitsulocho chiyenera kudulidwa mu nthawi.
Kumapeto kwa ntchito yosungunula, chitsulo chosungunuka chatha. Pofuna kupewa kuzirala kofulumira kumapanga ming’alu yayikulu mu ng’anjo yamoto, njira zoyenera zoziziritsa pang’onopang’ono ziyenera kuchitidwa, monga kuwonjezera mbale za asibesitosi pachivundikiro cha crucible; dzenje lapampopi latsekedwa ndi njerwa zotchinjiriza ndi mchenga wachitsanzo; Kusiyana pakati pa chivundikiro cha ng’anjo ndi pakamwa pa ng’anjo kumasindikizidwa ndi dongo losasunthika kapena mchenga wachitsanzo.
Kwa ng’anjo zosungunuka za crucible zokhala ndi mphamvu zokulirapo, mutatha kusungunula, yesetsani kupewa kuziziritsa kwathunthu kwa ng’anjoyo. Njira zotsatirazi zingagwiritsidwe ntchito:
(1) Khalani mbali ya chitsulo chosungunula mu ng’anjo ndi nyonga pa otsika voteji kusunga kutentha kwa chitsulo chosungunula pafupifupi 1300 ℃;
(2) Ikani chotenthetsera chamagetsi kapena gwiritsani ntchito choyatsira gasi mu crucible kuti kutentha kwa crucible kukhale 900~1100℃;
(3) Mukayimitsa ng’anjoyo, sindikizani chivundikiro cha ng’anjo, ndikuchepetsani madzi ozizira a inductor, kotero kuti ng’anjo ya ng’anjoyo imakhazikika pang’onopang’ono mpaka pafupifupi 1000 ℃, ndiyeno chipika chachitsulo chokhetsedwa mwapadera chokhala ndi mawonekedwe omwewo. monga crucible koma ang’onoang’ono kukula Yembekezani mu ng’anjo, ndi kulimbikitsa kutentha kusunga kutentha pa 1000 ℃. Pamene ng’anjo yotsatira iyamba kusungunula ntchito, ingot imagwiritsidwa ntchito ngati frit.
Ngati ng’anjo ikufunika kutsekedwa kwa nthawi yayitali, palibe chifukwa chokhalira kutentha kwa crucible. Pofuna kusunga bwino ng’anjo yamoto pansi pa madzi ozizira kwathunthu, chitsulo chosungunuka mu crucible chitatha, frit imakwezedwa ndipo kutentha kumakwera mpaka 800 ~ 1000 ℃, ndiye chivundikiro cha ng’anjo chimatsekedwa, mphamvu. wadulidwa, ndi ng’anjo Kutentha ndi kuziziritsa pang’onopang’ono. Ming’alu idzawoneka mosakayikira muzitsulo za crucible pambuyo poti ng’anjo yatsekedwa kwa nthawi yayitali. Akasungunukanso ndi kugwiritsidwa ntchito, ayenera kuyang’anitsitsa ndi kukonzanso. Mukasungunuka, kutentha kumayenera kukwezedwa pang’onopang’ono kuti ming’alu yaing’ono yomwe imapangidwa mu ng’anjo ya ng’anjo itseke yokha.
Panthawi yogwira ntchito ya ng’anjo, momwe ng’anjoyo imakhalira iyenera kuyang’aniridwa pafupipafupi kuti zitsimikizidwe kuti zikhale zotetezeka komanso zimasintha moyo wa ng’anjo. Njira zosayenera zogwirira ntchito nthawi zambiri zimapangitsa kufupikitsa moyo wa ng’anjo, choncho zolakwika zotsatirazi ziyenera kupewedwa:
(1) Chophimba cha ng’anjo sichimadulidwa, kuphikidwa ndi kutenthedwa motsatira ndondomeko yoperekedwa;
(2) Mapangidwe ndi mawonekedwe a kristalo azitsulo sizimakwaniritsa zofunikira, ndipo zimakhala ndi zonyansa zambiri
(3) Kutentha kwakukulu kwachitsulo chosungunula kumapeto kwa smelting kumapitirira malire ovomerezeka;
(4) Kugwira ntchito molakwika ndi kugwedezeka kwamphamvu kwamphamvu kunagwiritsidwa ntchito ponyamula zinthu zolimba kapena kutsekereza chifukwa cha kutulutsa kwa ng’anjo yamoto, zomwe zimawononga kwambiri zitsulo zotchinga;
(5) Pambuyo pa kutsekedwa kwa ng’anjo, ng’anjo ya ng’anjo imazimitsidwa ndipo ming’alu yayikulu imachitika.
Ngati ng’anjo imasokonekera, kuchuluka kwa madzi ozizira kwa sensa kumatha kuchepetsedwa moyenera, koma sikuloledwa kuzimitsa madzi ozizira, apo ayi kutentha kotsalira kwa ng’anjo ya ng’anjo kumatha kuwotcha wosanjikiza wa sensor. Pokhapokha pamene kutentha kwa pamwamba pa ng’anjo kutsika pansi pa 100 ° C, madzi ozizira a inductor akhoza kuzimitsidwa.
