DAIM NTAWV THOV
Cov hlau no feem ntau yog siv rau cov kav dej thiab cov flanges forged.
Kev ntaus nrig
LF1 thiab LF2 qib yuav zoo tagnrho yuav raug forged ntawm ib ncig ntawm 2250-2300ºF (1230-1260ºC) thiab ua tsis tau forged hauv qab 1650-1700ºF (900-925ºC.) Lub Qib LF3 yuav raug forged ntawm ib ncig ntawm 2150-2200ºF (1175-1205ºC) thiab ua tsis tauforged hauv qab 1700ºF (925ºC.)
VUAM/KHO KUB
Kev kho cua sov ntawm cov kav dej hlau yuav tsis muaj qhov tsis ntseeg tias yuav ua tiav tas mus li tom qab vuam. Cov qauv ntawm cov hlau no yuav raug txiav txim siab thawj zaug los ntawm cov txheej txheem dov / forging. Lub kav dej nws tus kheej yuav tau txais los ntawm cov hlau kub-kub dov, cov flanges thiab lwm yam los ntawm kev forgings. Cov txheej txheem vuam tiag tiag yuav yog qhov tseem ceeb hauv kev ua kom ntseeg tau tias qhov haum thiab kev ruaj ntseg ntawm cov kav dej thiab nws cov kev ua tau zoo tom qab. Kev kho cua sov ua ntej thiab tom qab cua sov yog qhov tseem ceeb.
Peb qib teev ntawm no yooj yim weldable los ntawm txhua txoj kev sim thiab kuaj.
Kev Siv Tau Tshuab
Hauv cov ntaub ntawv ntawm cov khoom siv forged thiab flanges, cov qib no tauyuav tsum tau ua kom raws li qhov xav tau, thiab kev paub dhau los yuav txiav txim siab seb qhov kev ua kom zoo tshaj plaws ntawm cov qauv forged, cov qauv normalized lossis cov qauv annealed. Txawm li cas los xij, vim yog qhov xwm txheej tseem ceeb ntawm kev siv kawg, cov lus qhia yuav tsum tau txais los ntawm lub tuam txhab kho cua sov uas tau lees paub..
