Kuvala kwachitsulo cha chromium chokwera kwambiri-chitoliro chosamva
High-chromium cast iron ndi anti-zovala zogwira ntchito bwino kwambiri, ndipo kapangidwe kake kake makamaka kamaphatikizapo carbon, chromium, manganese, silicon ndi maelementi ena. Mpweya wa carbon ndi wochuluka, ukhoza kufika kupitirira 3.0%, zomwe zili mu chromium nthawi zambiri zimakhala pafupifupi 26%, silicon ndi manganese ndizochepa, zinthuzi zimagwirira ntchito limodzi kuti zikhale ndi mphamvu, kulimba komanso kutentha kwakukulu kwa zinthuzo. Komanso, mkulu chromium kuponyedwa chitsulo mulinso kuchuluka koyenera aloyi zinthu monga faifi tambala, molybdenum ndi mkuwa, amene chromium ndi chinthu chachikulu, zili pakati pa 10% -30%, kawirikawiri 15% -22%. Nkhaniyi imadziwika chifukwa chokana kuvala kwambiri, kulimba kwambiri, kulimba kwambiri, komanso kutentha kwapamwamba komanso kukana dzimbiri, ndipo imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana oletsa kuvala.
Chitoliro chapamwamba cha chromium cast iron wear resistance chitoliro ndi chinthu chokhala ndi kukana kwamphamvu kwambiri komanso kukana dzimbiri, chomwe chimagwiritsidwa ntchito kwambiri m'magawo ambiri.
1. Zovala zapamwamba-zovala zachitsulo za chrome-zosagwira ntchito m'mafakitale amigodi, zimagwiritsidwa ntchito kwambiri potumiza makina amigodi. Chifukwa cha kuwonongeka kwa zinthu zanga, kugwiritsa ntchito -zinthu zosagwira ntchito kuti makina azikhala ndi moyo wabwino. High chromium kuponyedwa chitsulo kuvala kukana chitoliro ali mkulu kuvala kukana, akhoza bwino kukana kuvala kwa zipangizo, kuti patsogolo moyo utumiki wa makina.
2. Zovala zapamwamba-zovala zachitsulo zachromium-zosagwira ntchito zimagwiritsidwanso ntchito kwambiri m'makampani opanga magetsi. M'mafakitale a malasha,-mapaipi osamva chitsulo cha chromium amagwiritsidwa ntchito kwambiri potengera malasha ndi makina opera a malasha. Chifukwa cha kutha kwa zinthu zoyendera malasha komanso makina opera amalasha m'mafakitale a malasha-mafakitale amalasha, pakufunika kuvala-zinthu zosagwira ntchito kuti zida zikhale ndi moyo wathanzi. Chitoliro chapamwamba cha chromium choponyedwa chitsulo chimakhala ndi kukana kwamphamvu kwambiri, kumatha kukana kuvala kwazinthu, motero kumapangitsa moyo wautumiki wa zida.
3. Makampani opanga zida zomangira amavala chitsulo cha chromium chapamwamba-chitoliro chosamva pamakampani opanga zida zomangira amagwiritsidwanso ntchito kwambiri pantchito zomangira. Pafakitale ya simenti, kuvala kwachitsulo cha chromium chokwera kwambiri-chitoliro chosagwira ntchito kumagwiritsidwa ntchito kwambiri mu mphero za simenti ndi fani yayikulu ndi zida zina. Chifukwa cha zovuta kwambiri zogwirira ntchito za zipangizozi, kuvala kwakuthupi ndi kuwonongeka kwa mpweya kumayambitsa kuwonongeka kwakukulu kwa zipangizo. High chromium kuponyedwa chitsulo kuvala chitoliro kukana chitoliro ali mkulu kuvala kukana ndi kukana dzimbiri, akhoza bwino kukana kuvala kwa zipangizo ndi dzimbiri mpweya, motero kusintha moyo utumiki wa zida.
4. Zovala zapamwamba-zovala zachitsulo za chrome-zosamva zitoliro zimagwiritsidwanso ntchito kwambiri m'makampani opanga mankhwala. M'mafakitale, -mapaipi osamva chitsulo cha chromium amagwiritsidwa ntchito kwambiri m'ma reactor, mapampu ndi mavavu osiyanasiyana. Chifukwa cha kusagwira bwino ntchito kwa zidazi, dzimbiri la asidi, alkali, mchere ndi mankhwala ena komanso kuvala kwa zida kumayambitsa kuwonongeka kwakukulu kwa zida. High chromium kuponyedwa chitsulo kuvala kukana chitoliro ali mkulu kuvala kukana ndi kukana dzimbiri, akhoza bwino kukana kuvala kwa zipangizo ndi dzimbiri mankhwala, kuti kusintha moyo utumiki wa zida.
5. Kuphatikiza pa minda yomwe ili pamwambayi, kuvala kwachitsulo cha chrome{1}}chitoliro chosagwira ntchito kumagwiritsidwanso ntchito kwambiri pa ulimi wothirira. Mipaipi ya ulimi wothirira madzi nthawi zambiri imatha ndikuwonongeka chifukwa cha zinthu monga nthaka ndi mizu ya zomera. Kuvala kwachitsulo chachitsulo cha chrome-chitoliro chosagwira ntchito chimakhala cholimba kwambiri komanso kuti chisamachite dzimbiri, chomwe chimatha kuthana ndi kuwonongeka kwa zinthuzi ndikuwonetsetsa kuti ulimi wothirira umagwira ntchito bwino. Panthawi imodzimodziyo, chifukwa cha kulimba kwake kwamphamvu, imathanso kuchepetsa kusinthasintha kwa chitoliro m'malo ndi kuchepetsa mtengo wokonza. Kuphatikiza pa minda yomwe ili pamwambapa, chitoliro chapamwamba cha chitsulo chopanda chitsulo cha chrome chimagwiritsidwanso ntchito m'magawo ena ambiri. Mwachitsanzo, m'makampani amafuta amafuta, machubu achitsulo opangidwa ndi chrome apamwamba amagwiritsidwa ntchito kunyamula mafuta osapsa ndi zinthu zoyengedwa; m'makampani opanga zombo, machubu apamwamba a chrome otayira chitsulo amagwiritsidwa ntchito pamakina amafuta a sitima ndi ma hydraulic system; poyendera njanji, machubu olimba a chitsulo cha chrome akugwiritsidwa ntchito m'mabuleki a sitima, ndi zina zotero. Kugwiritsa ntchito m'maderawa kwasonyeza kufalikira kwa machubu a chromium cast iron wear apamwamba{9}}osamva.
