Tsim nyog rau cov ntawv thov zoo li qub, xws li cov springs thiab cov khoom siv me me elastic hauv cov tshuab zoo tib yam |
| Siv nyob rau hauv cov xwm txheej uas hnyav dynamic loads raug, xws li valve springs nyob rau hauv lub tsheb cav los yog lwm yam springs nrog siab qaug zog. |
Cov txheej txheem ntau lawm
Vim cov kev xav tau ntau dua ntawm kev ua haujlwmVDSiCr, kev tswj cov txheej txheem steelmaking, refining degree, kho cua sov thiab lwm yam kev sib txuas thaum lub sij hawm nws cov khoom yog nruj dua li ntawm FDSiCr. Nws xav tau cov cuab yeej tsim khoom ntau dua thiab cov txheej txheem meej tswj kom muaj kev ruaj ntseg ntawm cov hlau zoo thiab kev ua haujlwm zoo ib yam.
