Kumvetsetsa Njira Zochizira Pamwamba Pazitsulo Zosapanga zitsulo: Buku Lokwanira

M'dziko lazitsulo zopangidwa ndi zitsulo, chithandizo chapamwamba cha zitsulo zosapanga dzimbiri ndi njira yovuta kwambiri yomwe imapangitsa kuti zinthu zikhale zolimba, zokongola komanso zosagwirizana ndi dzimbiri. Ku Jindalai Steel Company, timakhazikika popereka zinthu zazitsulo zosapanga dzimbiri, ndipo timamvetsetsa kufunikira kwa njira zochizira pamwamba. Blog iyi ifufuza zaukadaulo wosiyanasiyana wazitsulo zosapanga dzimbiri, ndikuwunika kwambiri njira zodziwika bwino: pickling ndi passivation.

Kodi Njira Zochizira Pamwamba Pazitsulo Zosapanga zitsulo ndi ziti?

Njira zochizira pamwamba pazitsulo zosapanga dzimbiri zitha kugawidwa m'makina ndi mankhwala. Njira zamakina zimaphatikizirapo kupukuta, kugaya, ndi kuphulitsa, zomwe zimasintha pamwamba pake kuti zitheke bwino ndikuchotsa zolakwika. Komano, njira zama mankhwala zimaphatikizapo kugwiritsa ntchito njira zinazake kuti mukwaniritse zomwe mukufuna, monga kulimbikira kukana dzimbiri.

Pickling ndi Passivation: Njira Zofunika

Njira ziwiri zomwe zimagwiritsidwa ntchito kwambiri ndi mankhwala opangira zitsulo zosapanga dzimbiri ndi pickling ndi passivation.

Pickling ndi njira yomwe imachotsa ma oxides, sikelo, ndi zonyansa zina pamwamba pazitsulo zosapanga dzimbiri. Izi zimatheka pogwiritsa ntchito chisakanizo cha zidulo, monga hydrochloric kapena sulfuric acid. Kutolerako sikumangoyeretsa pamwamba komanso kumakonzekeretsanso chithandizo china, kuonetsetsa kuti zokutira kapena zomaliza zimamatira bwino.

Komano Passivation, ndi njira yomwe imapangitsa kuti oxide yachilengedwe ikhale yosanjikiza pazitsulo zosapanga dzimbiri, zomwe zimapereka chotchinga chowonjezera kuti chisawonongeke. Izi kawirikawiri zimatheka pochiza chitsulo ndi yankho lomwe lili ndi citric kapena nitric acid. Passivation ndiyofunikira pakusunga umphumphu wa chitsulo chosapanga dzimbiri m'malo ovuta, ndikupangitsa kuti ikhale gawo lofunikira kwambiri pakuchiritsa pamwamba.

Malangizo Enieni a Pickling ndi Passivation

Pankhani ya pickling ndi passivation, kutsatira malangizo enieni ndikofunikira kuti mupeze zotsatira zabwino.

1. Malangizo Ochizira Pickling:
- Onetsetsani kuti pamwamba pazitsulo zosapanga dzimbiri ndi zoyera komanso zopanda mafuta kapena dothi.
- Konzani njira yopangira pickling molingana ndi malangizo a wopanga, kuwonetsetsa kuti ma asidi ali olondola.
- Miwiritsani zitsulo zosapanga dzimbiri mu njira yothetsera nthawi yovomerezeka, nthawi zambiri kuyambira mphindi zochepa mpaka maola angapo, malingana ndi makulidwe a oxide wosanjikiza.
- Muzimutsuka bwino ndi madzi kuti muchepetse asidi ndikuchotsa zotsalira zilizonse.

2. Malangizo a Chithandizo cha Passivation:
- Mukatha kukolola, tsukani zitsulo zosapanga dzimbiri kuti muchotse asidi otsala.
- Konzani yankho la passivation, kuonetsetsa kuti likukwaniritsa zofunikira.
- Miwiritsani chitsulo chosapanga dzimbiri mu njira yopititsira patsogolo nthawi yoyenera, nthawi zambiri pakati pa mphindi 20 mpaka 30.
- Muzimutsuka ndi madzi osakaniza kuti muchotse njira yotsalira ndikuwumitsa magawowo.

Kusiyana Pakati pa Pickling ndi Passivation

Ngakhale kuti pickling ndi passivation ndizofunikira pazitsulo zosapanga dzimbiri, zimagwira ntchito zosiyanasiyana. Pickling imayang'ana kwambiri pakuyeretsa pamwamba ndikuchotsa zowononga, pomwe passivation ikufuna kupititsa patsogolo kusanjikiza kwa oxide, kukulitsa kukana kwa dzimbiri. Kumvetsetsa kusiyana kumeneku n'kofunika kwambiri posankha njira yoyenera yochiritsira potengera momwe akugwiritsira ntchito komanso momwe chilengedwe chikuyendera.

Mapeto

Ku Jindalai Steel Company, timazindikira kuti chithandizo chapamwamba cha zitsulo zosapanga dzimbiri si sitepe chabe pakupanga; ndi gawo lofunikira lomwe limatsimikizira moyo wautali ndi ntchito ya chinthu chomaliza. Pogwiritsa ntchito njira zamakono zothandizira zitsulo zosapanga dzimbiri, kuphatikizapo pickling ndi passivation, timaonetsetsa kuti katundu wathu akukwaniritsa miyezo yapamwamba kwambiri komanso yolimba. Kaya mukusowa zitsulo zosapanga dzimbiri zomangira, zamagalimoto, kapena makampani ena aliwonse, ukatswiri wathu pazamankhwala azitsulo amakutsimikizirani kuti mumalandira mayankho abwino kwambiri pazosowa zanu.
