Momwe Mungasungunulire Mkuwa Wosavuta

Kusankha zakuthupi
The zopangira kukoma ayenera kusintha ndi kukomamkuwamitundu.Mukasungunula mkuwa wosafunikira, ngati mtengo wake uli wodalirika, nthawi zina kugwiritsa ntchito zinthu zakale kumatha kufika 100%.Komabe, pofuna kuonetsetsa kuti chisungunukocho chikuyenda bwino komanso kuti chichepetse kuyaka, kugwiritsa ntchito ndalama zogawanika bwino monga utuchi kapena tchipisi ta zinki siziyenera kupitirira 30%.Kuyesa pamwamba: Mukamagwiritsa ntchito 50% cathode copper ndi 50% zamkuwa zamkuwa, nthawi yosungunula ndiyo yayitali kwambiri ndipo kugwiritsa ntchito mphamvu ndikokwera kwambiri.Ngati ingot ya zinc imatenthedwa mpaka 100 ~ 150 ℃ ndikudyetsedwa m'magulu, ndizopindulitsa kwambiri kuti imire ndikusungunuka mu dziwe losungunuka mwamsanga, zomwe zingachepetse kutaya kwachitsulo.Kuwonjezera pang'ono phosphorous akhoza kupanga zotanuka okusayidi filimu wopangidwa ndi 2ZnO.p2o2 pamwamba pa dziwe losungunuka.Kuwonjezera pang'ono zotayidwa, monga 0.1% ~ 0.2%, akhoza kupanga Al2O3 zoteteza filimu pamwamba pa dziwe losungunuka, ndi kuthandiza kupewa ndi kuchepetsa volatilization nthaka ndi kusintha zinthu kuponyera.Pamene zinthu zambiri zakale zimagwiritsidwa ntchito kusungunula mkuwa, chiwongola dzanja choyenera chiyenera kupangidwa pa zinthu zina zomwe zimatayika kwambiri.Mwachitsanzo, chiwongola dzanja cha zinki chisanachitike ndi 0.2% posungunula mkuwa wa zinki wochepa, chiwongolero cha zinki chisanachitike ndi 0.4% -0.7% pomwe mkuwa wapakati-zinki umasungunuka, ndipo chiwongolero cha zinc chisanachitike. 1.2% -2.0% pamene mkuwa wambiri wa zinki umasungunuka.
Kuwongolera njira yosungunuka
Dongosolo lazowonjezera pakusungunula mkuwa ndi: mkuwa, zinthu zakale ndi zinki.Mukasungunula mkuwa kuchokera kuzitsulo zenizeni, mkuwa uyenera kusungunuka poyamba.Nthawi zambiri, mkuwa ukasungunuka ndikutenthedwa ndi kutentha kwina, uyenera kusungunuka bwino (mwachitsanzo ndi phosphorous) ndiyeno nthaka iyenera kusungunuka.Pamene chiwongoladzanja chili ndi chiwongoladzanja chakale cha mkuwa, ndondomeko yotsatsira ikhoza kusinthidwa moyenera malinga ndi momwe zinthu zilili zenizeni monga mawonekedwe a zigawo za alloy ndi mtundu wa ng'anjo yosungunuka.Chifukwa zinthu zakale zokha zimakhala ndi zinc, kuti muchepetse kusungunuka kwa chinthu cha zinc, zinthu zakale zamkuwa ziyenera kuwonjezeredwa ndikusungunuka kumapeto.Komabe, zolipiritsa zazikulu sizoyenera kulipiritsa komaliza ndikusungunuka.Ngati mtengowo uli wonyowa, suyenera kuwonjezeredwa mwachindunji kusungunuka.Ngati chiwongolero chonyowa chikuwonjezedwa pamwamba pa ndalama zina zosasungunuka, zidzapanga nthawi yowumitsa ndi kutenthedwa musanayambe kusungunuka, zomwe sizothandiza kokha kupewa kusungunula inhalation, komanso kupewa ngozi zina.Zinc Kuwonjezera pa kutentha kochepa ndi mfundo yofunikira yomwe iyenera kutsatiridwa pafupifupi njira zonse zosungunulira mkuwa.Kuwonjezera nthaka pa kutentha otsika sikungangochepetsa kuyaka imfa ya nthaka, komanso kuthandiza chitetezo cha smelting ntchito.Mukasungunula mkuwa mu ng'anjo yoyatsira chitsulo, nthawi zambiri sikofunikira kuwonjezera deoxidizer chifukwa sungunulo lokha, ndiye kuti, dziwe losungunuka lokhazikika, lili ndi zinki yambiri.Komabe, pamene khalidwe losungunuka liri losauka, 0.001% ~ 0.01% phosphorous ikhoza kuwonjezeredwa molingana ndi kulemera kwa chiwongoladzanja chothandizira deoxidation.Kuonjezera kaphatikizidwe kakang'ono ka mkuwa wa phosphorous kusungunuka kungathe kuonjezera madzi osungunuka asanayambe kutuluka mu ng'anjo.Potengera chitsanzo cha H65 brass, malo ake osungunuka ndi 936 ° C.Pofuna kupanga mpweya ndi magazini mu sungunula kuyandama ndi kukhetsa mu nthawi, popanda kuchititsa zambiri volatilization zinki ndi inhalation wa kusungunula, kutentha kusungunula zambiri ankalamulira pa 1060 ~ 1100 ° C.Kutentha kumatha kukwezedwa moyenerera mpaka 1080 ~ 1120 ℃.Pambuyo "kulavulira moto" 2 mpaka 3 nthawi, imaponyedwa mu chosinthira.Phimbani ndi makala ophika panthawi yosungunula, ndipo makulidwe a chophimbacho chiyenera kukhala chachikulu kuposa 80mm.
