Chitsulo chachitsulo cha manganese chapamwamba chitha kugwiritsidwa ntchito pamakina osamva kuvala, kuphatikiza ma crushers, mphero za mpira, zonyamula katundu, zofukula, zidebe za bulldozer ndi masamba, ndi zolumikizira zomangira. Ikhoza kukonzedwa ndi kudula gasi ndi kuwotcherera zosiyanasiyana. Ngakhale mbale yachitsulo imakhala ndi mphamvu zambiri, imakhala ndi malo abwino opindika ozizira ndipo motero imatha kuzizira ndikupangidwa.

Chitsulo chachikulu cha manganese chili ndi 10-15% manganese. Mpweya wake wa carbon ndi wochuluka, nthawi zambiri 0.90-1.50%, ndipo nthawi zambiri, pamwamba pa 1.0%. Mitundu yake yamankhwala (%) ndi: C0.90-1.50, Mn10.0-15.0, Si0.30-1.0, S≤0.05,ndi P≤0.10. Uwu ndiye mtundu womwe umagwiritsidwa ntchito kwambiri pakati pamitundu yonse yazitsulo zapamwamba za manganese.

Chitsulo chachitsulo cha manganese nthawi zambiri chimagwiritsidwa ntchito ngati mbale ya mbale ndi chobvala chophwanyira nsagwada, mbale ya nsagwada ndi mbale yam'mbali ya zophwanya nsagwada, mbiya zophwanyira, mphero za mpira, nyundo zafulati, nyundo, ndi dzino la ndowa zofukula, etc. .

Chibwano chophwanyira nsagwada chomwe timapanga chimapangidwa ndi zida zapamwamba kwambiri kudzera munjira zothira. Kuphatikiza pa chitsulo chochuluka cha manganese, chromium imawonjezedwa kuti ipangitse kuuma kwa chinthucho, kupangitsa kuti mankhwalawo azikhala okhazikika ndikuwonetsetsa kuti makina ake amapangidwa. Nthawiyi, madzi toughening mankhwala anatengera. Pambuyo pamankhwala owumitsa madzi, kuponyera kumakhala ndi mphamvu zolimba kwambiri, ductility, pulasitiki komanso osati maginito, zomwe zimapangitsa kuti mbale ya mano ikhale yolimba. Pamene mphamvu yamphamvu kapena kupunduka kuchokera ku kupsinjika kwakukulu kumachitika ku chinthu panthawi yogwiritsira ntchito, kuuma kwa ntchito kumapanga pamwamba, motero kumapanga kusanjikiza kwambiri pamwamba, pamene wosanjikiza wamkati amasunga ductility wabwino ndipo amatha kupirira katundu wodabwitsa ngakhale atakhalapo. amavalidwa ku mlingo woonda kwambiri.

The mkulu manganese zitsulo liner mbale ya mpira mphero timatulutsa ndi mkulu kuvala kukana, mkulu mphamvu, ductility wabwino, kukana mphamvu, ntchito mkulu mtengo ndi amphamvu kusinthasintha. Pogwiritsa ntchito njira zamakono, timapanga zotheka kuti mbale ya liner ikhale ndi kukana kwabwino, kupititsa patsogolo mphamvu ya mphero yamagetsi pa zipangizo, kupititsa patsogolo kugaya kwa mphero, kuonjezera kutulutsa ndi kuchepetsa kugwiritsa ntchito zitsulo. . Ndi sayansi yochokera ku sayansi komanso njira yoyenera, mbale ya liner imatha kunyamula mphamvu yayikulu, ndikusunga mawonekedwe ake kwanthawi yayitali ikugwira ntchito, kuti iwonetsetse kuchulukira kokhazikika kwa zotulutsa. Mu quenching ndondomeko ya mpira mphero mkulu manganese zitsulo liner mbale, wapadera kawiri-zotsatira quenchant ndi kukhazikika bwino matenthedwe ntchito ngati sing'anga, kulola mankhwala kukwaniritsa mkulu mphamvu, kuuma ndi ductility kukwaniritsa zofunika luso pa kuvala kukana. Poyerekeza ndi mbale za liner wamba, mbale ya liner yomwe timapanga imakhala yotsika mtengo kwambiri ndipo imatha kugwiritsidwa ntchito m'migodi pogaya mphero zonyowa, mphero zowuma komanso mphero zosakanikirana.
