Kodi kuchotsa dzimbiri kanasonkhezereka zitsulo chitoliro?
Choyamba, ikani zosungunulira kunja kwa zitsulo kuchotsa zinthu zamoyo.Dzimbiri angathenso kuchotsedwa pickling pambuyo kutsuka dzimbiri kupewa, kuyeretsa kapena chitsulo, dzimbiri, kuwotcherera slag, etc. Galvanizing lagawidwa mu ❖ kuyanika thermoelectric ndi ozizira ❖ kuyanika.Kupaka kwa thermoelectric sikophweka kuchita dzimbiri komanso kuzizira kumakhala kosavuta kuchita dzimbiri.

Chitoliro chaposachedwa chamadzi amoto tsopano chimagwiritsa ntchito chitoliro chamalata, ndipo chitoliro chakunja chamalata chimagwiritsidwa ntchito pansanjika ya utoto.Zitha kuwoneka kuti chitoliro chozimitsa moto kwenikweni ndi malata.Mu kapangidwe kazitsulo, uinjiniya wowotcherera umagwira nawo ntchito.Choncho, ntchito pafupipafupi kanasonkhezereka zitsulo chitoliro chingalepheretse zimachitika dzimbiri zinthu kwa nthawi yaitali.

Kusakaniza kwachitsulo kumatengedwa ngati chitsulo cha alloy pamene manganese ndi aakulu kuposa 1.65%, silicon kupitirira 0.5%, mkuwa pamwamba pa 0.6%, kapena zinthu zina zochepa zowonjezera monga chromium, nickel, molybdenum, kapena tungsten zilipo.Mitundu yambiri yamitundu yosiyanasiyana imatha kupangidwira chitsulocho polowetsa zinthu izi mu Chinsinsi.

Njira yokonzanso zitsulo zosapanga dzimbiri pochepetsa mpweya wa carbon

Kuchuluka kwa mpweya muzitsulo zosapanga dzimbiri kuyenera kukhala kocheperako poyerekeza ndi chitsulo cha kaboni kapena chitsulo chochepa cha aloyi (ie chitsulo chokhala ndi alloying element pansi pa 5%).Ngakhale ng'anjo yamagetsi yamagetsi (EAF) ndi njira wamba yosungunula ndi kuyenga zitsulo zosapanga dzimbiri, AOD ndiyowonjezera pazachuma, chifukwa nthawi yogwira ntchito ndi yayifupi komanso kutentha kumakhala kotsika kuposa kupanga zitsulo za EAF.Kuphatikiza apo, kugwiritsa ntchito AOD pakuyenga zitsulo zosapanga dzimbiri kumawonjezera kupezeka kwa EAF pazolinga zosungunuka.

Chitsulo chosungunuka, chosayeretsedwa chimasamutsidwa kuchokera ku EAF kupita ku chotengera china.Kusakaniza kwa argon ndi okosijeni kumawombedwa kuchokera pansi pachombocho kudzera muzitsulo zosungunuka.Mankhwala oyeretsa amawonjezeredwa ku chotengera pamodzi ndi mpweya umenewu kuti athetse zonyansa, pamene mpweya umaphatikizana ndi carbon muzitsulo zosakanizidwa kuti zichepetse mpweya wa carbon.Kukhalapo kwa argon kumawonjezera kuyanjana kwa mpweya wa mpweya ndipo motero kumathandizira kuchotsa mpweya.

Kuwonongeka kwachitsulo chokhazikika ndi njira ya electrochemical yomwe imafuna kupezeka kwa chinyezi ndi mpweya panthawi imodzi.Kupanda kutero, dzimbiri sizichitika.Kwenikweni, chitsulo muzitsulo chimapangidwa ndi okosijeni kuti chipange dzimbiri, zomwe zimakhala pafupifupi ka 6 kuchuluka kwa zinthu zoyamba zomwe zimadyedwa panthawiyi.Mchitidwe wa dzimbiri wamba wafotokozedwa apa.
