Njira yochiza ya ngozi ya makina osungunula induction
Chithandizo njira ya induction smelting machine ngozi
Ngozi sizidziwika. Kuti muthane ndi ngozi zosayembekezereka modekha, modekha, komanso molondola, mutha kuteteza ngozi kuti isakule ndikuchepetsa kuchuluka kwa zomwe zimachitika. Chifukwa chake, ndikofunikira kudziwa bwino za ngozi zomwe zingachitike ndi smelter yoyambira, komanso njira yolondola yothanirana ndi ngozizi.
1. Makina osungunula a induction satha mphamvu chifukwa cha ngozi monga overcurrent and grounding of power supply network kapena ngozi ya induction smelting machine yokha. Pamene dera lolamulira ndi dera lalikulu likugwirizanitsidwa ndi gwero lamphamvu lomwelo, pampu yamadzi yoyendetsera madzi imasiyanso kugwira ntchito. Ngati kutha kwa magetsi kungathe kubwezeretsedwanso kwakanthawi kochepa, ndipo kutha kwa magetsi sikudutsa mphindi 5, palibe chifukwa chogwiritsa ntchito gwero lamadzi losunga zobwezeretsera, dikirani kuti mphamvuyo ipitirire. Koma pakadali pano, kukonzekera kwa gwero lamadzi lomwe likuyenera kukhazikitsidwa ndikofunikira. Ngati mphamvu yazimitsidwa kwanthawi yayitali, chosungunulira chosungunula chimatha kulumikizidwa nthawi yomweyo ndi gwero lamadzi losunga. Gwero la madzi limaperekedwa ndi wogwiritsa ntchito.
2. Ngati mphamvu yazimitsidwa ndi yopitilira mphindi zisanu, gwero lamadzi loyimilira liyenera kulumikizidwa. Nthawi iliyonse ng’anjoyo ikayatsidwa, fufuzani ngati gwero la madzi loyimilira lili bwino.
3. Chifukwa cha kulephera kwa mphamvu ndi kuyimitsidwa kwa madzi a koyilo, kutentha komwe kumachitika kuchokera kuchitsulo chosungunula kumakhala kwakukulu kwambiri. Ngati madzi sakuyenda kwa nthawi yayitali, madzi a mu koyilo amatha kukhala nthunzi, zomwe zingawononge kuziziritsa kwa koyilo, ndipo chubu la rabara lomwe limagwirizanitsidwa ndi koyilo ndi kutsekemera kwa koyilo lidzawotchedwa. Chifukwa chake, pakutha kwamphamvu kwanthawi yayitali, sensa imatha kusinthidwa kukhala madzi am’mafakitale kapena kuyambitsa pampu yamadzi yadzidzidzi yamafuta amafuta. Kuzimitsa magetsi chifukwa cha makina osungunula opangira induction
Momwemo, kotero kuti madzi a koyilo akuyenda ndi 1/3 mpaka 1/4 ya smelting yamphamvu.
4. Ngati nthawi yozimitsa mphamvu ndi yosakwana 1h, sungani madzi achitsulo pamwamba ndi makala kuti muteteze kutentha, ndipo dikirani kuti mphamvuyo ipitirire. Nthawi zambiri, palibe njira zina zomwe zimafunikira, komanso kutentha kwachitsulo chosungunuka kumakhalanso kochepa. Kwa ng’anjo ya 6t, kutentha kumatsika ndi 50 ℃ kokha mphamvu itatha kwa 1h.
5. Ngati nthawi yozimitsa mphamvu ndi yoposa 1h, pazitsulo zazing’ono zosungunula, chitsulo chosungunuka chikhoza kulimba. Ndi bwino kusintha mphamvu ya mpope yamafuta kuti ikhale yosungira mphamvu pamene chitsulo chosungunula chikadali madzimadzi (magetsi adzidzidzi amaperekedwa ndi wogwiritsa ntchito), kapena gwiritsani ntchito mpope wosungira pamanja kutsanulira chitsulo chosungunula panthawi yadzidzidzi. choyimirira chitsulo chosungunula ladle kapena mu dzenje ladzidzidzi kutsogolo kwa ng’anjo , Thumba ndi dzenje ziyenera kukhala zouma komanso zopanda zinthu zina zoyaka ndi kuphulika. Kuchuluka kwa choyikirapo chachitsulo choyimirira mwadzidzidzi ndi dzenje ladzidzidzi kuyenera kukhala kokulirapo kuposa kuchuluka kwa choyezera choyezera. Payenera kukhala chivundikiro chachitsulo cha gululi pamwamba pa dzenje ladzidzidzi, ngati chitsulo chosungunuka chotsalacho chalimba mu crucible. Komabe, chifukwa cha zifukwa zosiyanasiyana, chitsulo chosungunuka sichingatsanulidwe kwakanthawi, ndipo ferrosilicon ena akhoza kuwonjezeredwa kuti achepetse kutentha kwachitsulo chosungunuka ndikuchedwetsa kulimba kwake. Ngati chitsulo chosungunula chayamba kulimba, yesani kuwononga kutumphuka wosanjikiza pamwamba ndi kukhomerera dzenje. Chosungunula chachikulu chosungunula chimakhomerera mabowo 3 mpaka 6 kuti atsegule mkati kuti athandizire kuchotsedwa kwa gasi atasungunuka ndikuletsa mpweya kuti usakule ndikupangitsa ngozi ya kuphulika.
6. Pamene chiwongolero cholimba chikhala champhamvu ndikusungunuka kachiwiri, ndi bwino kupendekera kutsogolo kwa smelter pakona inayake, kuti chitsulo chosungunuka chomwe chili pansi chitulutse mbali ina ya m’munsi mwake kuti zisawonongeke.
7. Pali kuzima kwa magetsi panthawi yomwe kuzizira kumayamba kusungunuka. Mlanduwu sunasungunuke kwathunthu ndipo sufunika kukanidwa. Zisungeni momwe zilili, pitirizani kupereka madzi, ndipo dikirani kuti mphamvu yotsatira iyambe kusungunuka.
