Nta ntawm cam khwb cia hlau pob:
(1) Tshab saum npoo: Qhov chaw nres nkoj muaj ntxhib yog qhov sib xyaw ua ke thiab deformation thiab poob ntawm kev sib tw thaum siv;
(2) Sab hauv kev xoob: Vim yog cov qauv sab hauv ntawm lub pob yog ntxhib, nrog qhov kev cuam tshuam loj thiab tsawg cuam tshuam nyuaj thaum siv. Cov pob loj dua thiab cov loj dua lub zeb, muaj ntau txoj kev tawg;
(3) Tsis tsim nyog rau cov chaw sib tsoo ntub: cov hnav tsis kam ntawm cov khoom pov tseg nyob ntawm cov ntsiab lus chromium. Ntau dua cov ntsiab lus chromium, ntau cov hnav-tiv taus nws yog. Txawm li cas los xij, cov yam ntxwv ntawm chromium yog tias nws yooj yim rau corrode. Ntau dua cov chromium, qhov yooj yim dua yog yuav corroded, tshwj xeeb tshaj yog cov chromium hauv ore. Sulfur, vim siv cov khoom siv chromium nyob rau hauv cov kev sib tsoo ntub dej los ntub, tus nqi yuav nce thiab cov zis yuav txo.
Nta ntawmtiv thaivCov pob zeb:
(1)Du nto: ua los ntawm kev quav ntseg txheej txheem, cov nplaim tsis muaj qhov tsis xws, tsis muaj deformation, tsis muaj kev poob ntawm kev sib tw, thiab tswj cov nyhuv zoo heev.
(2)Sab hauv nruj: vim tias nws yog forged los ntawm round hlau, tsis xws li tshwm sim los ntawm cov txheej txheem pov thawj hauv lub xeev cam khwb cia. Qhov ceev sab hauv sab hauv yog qhov siab thiab qhov zoo kawg nkaus yog qhov siab, uas ua rau lub pob poob qis thiab cuam tshuam tawv, yog li txo lub pob tawg.
(3)Ob qho tib si sib tsoo thiab ntub dej yog ua tau: Vim yog siv cov khoom lag luam zoo li qub tau tsim los ntawm peb lub tuam txhab uas yus tswj hwm cov ntsiab lus Chromium, yog li txhim kho cov ntsiab lus chromium, yog li kev txhim kho zoo heev. Txhim kho, cov pob txheem no yog qhov tsim nyog rau cov haujlwm ua haujlwm uas cov mines feem ntau ntub kev sib tsoo.
