Kuyenga wothandizila angagwiritsidwe ntchito ankagwiritsa ntchito zitsulo smelting ndi kuponyera makampani, ndi zosiyanasiyana zinthu anaphatikizana, kuwonjezera yabwino kusungunula zitsulo. Mu ndondomeko ya smelting zitsulo deoxidation, desulfurization, phosphorous kuchotsa, kuchotsa mpweya ndi zovuta kwambiri, tsopano ndi woyenga wothandizila akhoza mogwira kuchotsa zonyansa zamitundu yonse, kuti chitsulo choyera kwambiri.

Kuonjezera woyenga kumathandiza kwambiri kusungunula zitsulo

Ngatinso mu ndondomeko smelting zitsulo popanda yake kuchotsa mpweya ndi zosafunika, padzakhala porosity, ming'alu, ozizira kulekana, shrinkage ndi zolakwika zina, chifukwa cha kuchepa kwa mankhwala khalidwe. Pambuyo powonjezera kuyenga wothandizila akhoza kuthetsa zofooka luso anakumana mu ndondomeko zitsulo kuponyera, pambuyo powonjezera akhoza yeretsani njere, kumapangitsanso fluidity wa zitsulo, ndipo yake kusaganizira zosafunika mu zitsulo Sungunulani.

Komanso, mu smelting ndondomeko zitsulo adzakhala wothira oxides osiyanasiyana, sulfides, silicates, etc., pambuyo kuwonjezera zonyansa izi akhoza kuchotsedwa kusintha makina katundu zitsulo. Pakusungunula, ngati chitsulo chamadzimadzi chikukhudzana ndi mlengalenga, padzakhala zolakwika zamtundu wa porosity, kotero kuti mpweya wazitsulo muzitsulo uyenera kuchotsedwa panthawi yake kuti ukhale wabwino.

Kuwonjezera akhoza kuyeretsa zitsulo Sungunulani, yake kuthetsa utsi mpweya mu Sungunulani, ndi ntchito zoonekeratu za deoxygenation, desulfurization ndi dephosphorization, motero kuchepetsa zili zosafunika mu Sungunulani. Kuwonjezera kwa woyengetsa wothandizira kungathe kulekanitsa zotsalirazo, mwa kusakaniza ndi madzi kuti athetse bwino mpweya wotulutsa mpweya ndikuletsa mapini, kuphatikizapo kupewa slag, phulusa, porosity, nodules, zipinda zozizira ndi zolakwika zina.

Woyenga wothandizila ayenera kugwiritsidwa ntchito mogwirizana ndi njira ochiritsira, chifukwa kuchuluka kwa woyenga wothandizila ndi ochepa, kotero inu simungakhoze kuyembekezera kuchepetsa alipo ndi deoxidation amatha pokonza. Ngati pali crusts ndi slag pamwamba pa smelting ndondomeko, pamwamba zoyandama slag ayenera kuchotsedwa mu nthawi pamaso kuthira.
