Uncover Cov Cast Iron nyob rau hauv "magic Element" Titanium Magic Role

Nyob rau hauv cov txheej txheem smelting ntawm cam khwb cia hlau, muaj ib lub ntsiab uas plays lub luag hauj lwm tseem ceeb, uas yog titanium. Nws yog zoo li lub caij nrog cov khawv koob, muaj peev xwm hloov cov yam ntxwv thiab kev ua tau zoo ntawm cov hlau cam khwb cia, nqa qhov tsis muaj qhov kawg rau kev tsim thiab siv cov cam khwb cia hlau.
Ua ntej tshaj plaws, titanium muaj peev xwm ua kom muaj zog los tiv thaiv cov ntsiab lus nitrogen siab. Thaum cov ntsiab lus nitrogen hauv cam khwb cia hlau siab dhau, nws tuaj yeem ua rau muaj qhov tsis xws li porosity, uas cuam tshuam rau qhov zoo ntawm cov cam khwb cia hlau. Titanium, ntawm qhov tod tes, muaj peev xwm ntawm kev sib xyaw nrog nitrogen thiab cov pa roj carbon monoxide los tsim cov xim liab titanium carbon-nitride hais, uas ua rau muaj kev cuam tshuam tsis zoo ntawm nitrogen. Tsis tas li ntawd, qhov tsim nyog ntawm titanium txhawb kev tsim cov khoom zoo D- thiab E-hom graphite, uas yog qhov tseem ceeb tshwj xeeb hauv kev tsim cov iav fwj pwm thiab silicon-muaj cov cua sov-resistant cam khwb cia hlau, txo qhov nkag ntawm oxides rau hauv lub graphite flake thiab txhim kho lub durability ntawm cam khwb cia hlau.
Txawm li cas los xij, qhov ntawd tsis yog txhua yam titanium tuaj yeem ua tau. Nyob rau hauv cov hlau cam khwb cia hlau, txawm hais tias muaj ntau dhau ntawm titanium yuav tsum tau zam, vim tias titanium ntau dhau tuaj yeem ua rau muaj qhov tsis xws li hydrogen pinholes, qee zaum, los ntawm kev tswj hwm tus nqi ntawm titanium, nrog rau kev sib ntxiv ntawm lwm cov ntsiab lus alloying, peb. Txawm tias muaj peev xwm ua kom zoo dua ntawm titanium cov khoom los txhim kho microstructure ntawm cov hlau cam khwb cia hlau thiab txhim kho nws cov khoom siv kho tshuab.

Rau zus tau tej cov creep cam khwb cia hlau, titanium plays lub luag hauj lwm ntawm inhibiting lub tsim ntawm spheroidal graphite. Nyob rau hauv txoj kev kho magnesium, los ntawm kev tswj hwm tus nqi ntawm titanium ntxiv, peb tuaj yeem paub txog qhov ua tiav ntawm cov hlau cam khwb cia, thiaj li tau txais kev ua haujlwm zoo ntawm cov hlau cam khwb cia.
Titanium kuj tseem ua lub luag haujlwm tseem ceeb hauv cam khwb cia hlau uas muaj 30% chromium. Los ntawm kev ntxiv tus nqi ntawm titanium, peb tuaj yeem ua kom zoo dua qub ntawm cov khoom lag luam ntawm cov hlau cam khwb cia, ua kom nws lub zog tensile, txo qhov nyiam ntawm thermal cracking, yog li txhim kho cov khoom siv ntawm cov hlau cam khwb cia.
Yog li cas koj zoo ntxiv titanium rau cam khwb cia hlau? Qhov no yeej yog ib txoj hauj lwm technical. Peb tuaj yeem xaiv siv cov khoom seem hlau titanium, titanium-hlau alloy, titanium-muaj ferrosilicon thiab lwm yam ntaub ntawv raws li qhov chaw ntawm titanium. Thaum lub sij hawm ntxiv txheej txheem, peb yuav tsum tau tswj qhov tsim nyog kub thiab ceev kom ntseeg tau tias titanium tuaj yeem sai sai thiab tag nrho yaj hauv cov dej hlau kom tsis txhob oxidation poob. Tsis tas li ntawd, peb yuav tsum xav txog cov ntsiab lus titanium uas yuav muaj nyob rau hauv cov ntaub ntawv raw thiaj li xam cov titanium kom raug ntxiv.
Hauv kev xaus, titanium, uas yog ib qho tseem ceeb ntawm cov hlau cam khwb cia, muaj ntau yam kev ua haujlwm zoo. Los ntawm kev tshawb fawb thiab tsim nyog tswj tus nqi ntawm titanium ntxiv thiab txoj kev nws ntxiv, peb tuaj yeem ua kom zoo dua cov microstructure thiab cov khoom siv hluav taws xob ntawm cov hlau cam kom tau raws li qhov xav tau ntawm kev siv sib txawv. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho txuas ntxiv ntawm cov txheej txheem, peb ntseeg tias daim ntawv thov ntawm titanium hauv cam khwb cia hlau yuav yog qhov dav thiab qhov tob.
