Raws li cov xwm txheej sib txawv, cov khoom siv hlau yog rhuab mus rau qhov kub thiab txias, thiab tom qab ntawd txias hauv ntau txoj hauv kev los hloov cov qauv metallographic ntawm cov khoom siv hlau thiab tau txais cov khoom tsim nyog.Cov txheej txheem no feem ntau hu ua cov khoom siv hlau ua kom sov.Peb cov txheej txheem dab tsi suav nrog hauv kev kho cua sov ntawm carbon steel hlab?

Kev kho cua sov ntawm cov ntaub ntawv hlau yog muab faib ua kev kho cua sov tag nrho, kev kho cua sov saum npoo thiab kev kho cua sov.Kev kho cua sov ntawm carbon seamless steel raj feem ntau txais kev kho cua sov tag nrho.

Cov kav hlau hlau yuav tsum tau mus los ntawm cov txheej txheem yooj yim xws li cua sov, txuag hluav taws xob thiab cua txias thaum kho cua sov.Hauv cov txheej txheem no, cov kav hlau steel yuav muaj qhov tsis zoo.Kev kho cua sov tsis xws luag ntawm cov yeeb nkab steel feem ntau suav nrog cov qauv tsis tsim nyog thiab kev ua haujlwm ntawm cov kav hlau steel, qhov ntev tsis tsim nyog, tawg tawg, khawb, oxidation hnyav, decarburization, overheating lossis overburning, thiab lwm yam.

Thawj txheej txheem ntawm carbon steel tube cua sov kho yog cua sov.Muaj ob qhov cua kub sib txawv: ib qho yog cua sov hauv qab ntawm qhov tseem ceeb Ac1 lossis Ac3;lwm qhov yog cua sov tshaj qhov tseem ceeb ntawm Ac1 lossis Ac3.Nyob rau hauv ob qhov cua kub kub, qhov kev hloov ntawm cov yeeb nkab steel yog txawv kiag li.Cov cua kub hauv qab ntawm qhov tseem ceeb Ac1 lossis AC3 yog qhov tseem ceeb kom ruaj khov ntawm cov hlau thiab tshem tawm cov kev ntxhov siab sab hauv ntawm cov yeeb nkab steel;Cov cua kub saum Ac1 lossis Ac3 yog austenitize cov hlau.

Qhov thib ob txheej txheem ntawm carbon steel tube cua sov kho yog thaum tshav kub kub preservation.Nws lub hom phiaj yog txhawm rau ntsuas qhov ntsuas kub ntawm cov yeeb nkab steel kom tau txais cov qauv cua sov tsim nyog.

Qhov thib peb txheej txheem ntawm carbon steel raj cua sov kho yog txias.Cov txheej txheem cua txias yog cov txheej txheem tseem ceeb ntawm steel yeeb nkab kho cua sov, uas txiav txim siab cov qauv metallographic thiab txhua yam khoom ntawm cov yeeb nkab steel tom qab txias.Hauv kev tsim khoom tiag tiag, muaj ntau txoj hauv kev txias rau cov kav hlau.Feem ntau siv cov txheej txheem cua txias xws li cua txias, cua txias, roj txias, polymer txias, dej txias, thiab lwm yam.
