Cov yam tseem ceeb uas cuam tshuam raurov ua dua lub sijhawmntawmhlau txhaj / gritfeem ntau suav nrog qhov zoo ntawm cov hlau (cov khoom siv, qhov nyuaj, qhov ceev, qhov tsis zoo sab hauv), cov txheej txheem tsim khoom (kev tswj cov txheej txheem tsim khoom), ib puag ncig ua haujlwm (xws li cov av noo lossis cov xov xwm corrosive), thiab txoj kev siv (kev sib phim qhov nyuaj, zaus ntxuav, thiab kev txawj ua haujlwm). Cov yam no ua ke txiav txim siab qhov hnav thiabrelub voj vooglub sijhawmntawm cov hlau txhaj / grit.
Cov Khoom Siv thiab Qhov Zoo
Khoom siv: Cov ntaub ntawv sib txawv (hlau cam khwb cia, hlau tsis xeb, hlau sib xyaw) muaj qhov ruaj khov sib txawv. Hlau tsis xeb yog cov khoom siv uas tiv taus xeb, thaum hlau cam khwb cia yog cov khoom siv uas pheej yig tab sis yooj yim puas tsuaj.
Qhov nyuaj thiab qhov ceev:Kev txhaj tshuaj hlaunrog rau qhov nyuaj nruab nrab (tawv dhau thiab nws tawg yooj yim, mos dhau thiab nws hnav sai) thiab qhov ceev siab muaj lub neej ntev dua, tuaj yeem tiv taus kev cuam tshuam siab, thiab tsis tshua muaj kev tawg.
Qhov Tsis Zoo Sab Hauv: Qhov porosity, kab nrib pleb, thiab qhov shrinkage ua rau lub neej luv dua.
Cov Txheej Txheem Tsim Khoom
Kev Kho Mob Kub: Cov txheej txheem quenching thiab tempering zoo yog qhov tseem ceeb rau kev ua kom muaj zog sib xws thiab hnav tsis kam ntawmhlau txhaj.
Kev Tswj Xyuas Kev Tsim: Xyuas kom meej tias muaj qhov ntev sib xws thiab lub voj voog zoo kom txo qhov poob ntawm qhov txhaj tshuaj tsis xwm yeem.
Ib puag ncig ua haujlwm
Kev Huv Si: Qhov huv ntawm qhov chaw ua haujlwm thiab tsis muaj cov khoom tsis huv.
Av noo: Cov chaw noo noo yooj yim ua rau xeb (tshwj xeeb tshaj yog cov hlau uas muaj carbon tsawg), cuam tshuam rau nws cov khoom siv thiab lub neej ntev.
Kev xeb: Cov tshuaj lom neeg ua rau xeb sai dua; cov hlau tsis xeb muaj qhov zoo dua hauv qhov chaw ib puag ncig no.
Kev Ua Haujlwm thiab Kev Siv:
Kev Sib Tw Qhov Nyuaj: Qhov nyuaj ntawm cov hlau txhaj yuav tsum phim qhov nyuaj thiab qhov ntxhib ntawm qhov chaw ua haujlwm uas yuav tsum tau ntxuav. Qhov nyuaj dhau yuav ua rau nws tus kheej hnav sai dua.
Siv Zaus: Kev tua phom/zom zaus ntau dua ua rau hnav sai dua.
Cov Txheej Txheem Ua Haujlwm: Cov yam ntxwv ntawm cov khoom siv kom raug (qhov ceev ntawm huab cua, lub kaum sab xis ntawm lub tshuab tawg) tuaj yeem txo qhov hnav tsis zoo.
Kev xaus lus: Zoo heev, ceev ceevhlau txhaj/grittsis muaj qhov tsis zoo sab hauv, nyob rau hauv qhov nyuaj thiab ib puag ncig tsim nyog, ua ke nrog kev ua haujlwm kom zoo, tuaj yeem ua tiav qhov ntev tshaj plawsrov ua dua lub sijhawm.
