Hom thiab kev siv ntawm Tuam Tshoj Cast Carbon Steel
Tshaj tawm los ntawmAdmin
Muaj ntau ntau hom cam khwb cia Carbon Steel muaj nyob rau hauv kev ua lag luam.Cov hlau no tau muab faib ua ntau pawg nyob ntawm kev siv lawv npaj rau.Lawv tau muab faib ua peb hom tseem ceeb, uas yog annealed, normalized thiab stainless hlau.Lawv tseem tuaj yeem muab faib ua cov txheej txheem, tshuab tsim thiab cov hlau alloy.Cov khoom ntawm cov hlau no nyob ntawm seb hom kev kho cua sov thiab cov ntsiab lus carbon.Ntxiv rau qhov ntawd, lawv cov hardness qhov tseem ceeb nyob ntawm seb hom kev kho cua sov.Qhov sib xyaw ntawm cam khwb cia Carbon Steel nyob ntawm nws cov ntsiab lus ntawm carbon.Cov khoom siv alloying no yog qhov tseem ceeb tshaj plaws.Cov seem ntawm cov ntsiab lus yog cov lej.Ntawm cov khoom no yog silicon, manganese, thiab hlau.Cov uas muaj cov ntsiab lus qis ntawm cov ntsiab lus no hu ua low-alloy steels.High-quality cam khwb cia Carbon Steels feem ntau muaj ntau tshaj 0.5% carbon.Lawv paub txog lawv lub zog siab, toughness, thiab tus nqi qis.Muaj ntau txoj hauv kev los ntsuas lub zog thiab tawv ntawm cam khwb cia Carbon Steel.Piv txwv li, lub dav hlau-strain fracture toughness yog txiav txim los ntawm SN nkhaus.Cov ntaub ntawv no tuaj yeem siv rau hauv cov qauv sib npaug.Rau kev qaug zog, SN nkhaus yog ib qho piv txwv ntawm kev sib raug zoo ntawm lub neej thiab kev qaug zog.Nws lub neej muaj feem xyuam rau qhov siab tshaj plaws kev ntxhov siab thov.Kev ntsuam xyuas tas li-amplitude yog siv los txiav txim siab qhov rhiab heev ntawm cov khoom kom qaug zog.Lwm txoj hauv kev los ntsuam xyuas lub zog ntawm cov hlau yog los ntawm kev tawg toughness.Muaj ntau qhov kev ntsuam xyuas los ntsuas qhov hnyav, suav nrog Charpy V-notch impact test, drop-weight test, and the dynamic tear test.Ntxiv mus, cov txheej txheem tshwj xeeb yog siv los ntsuas lub dav hlau-strain fracture toughness.Tsis tas li ntawd, SN nkhaus muab cov ntaub ntawv ntawm lub zog ntawm cov khoom.SN nkhaus qhia txog kev sib raug zoo ntawm lub neej ntawm tus qauv qaug zog thiab qhov siab tshaj plaws thov kev ntxhov siab.Muaj ntau hom Carbon Steel.Muaj cov pa roj carbon tsawg thiab high-carbon steels.Qhov sib txawv ntawm lawv yog nyob rau hauv tus nqi ntawm carbon nyob rau hauv cov hlau.Cov hlau nruab nrab muaj cov pa roj carbon tsawg dua 0.2 feem pua ntawm cov pa roj carbon monoxide thiab cov pa roj carbon ntau muaj nyob nruab nrab ntawm 0.2% thiab 0.5 feem pua ntawm cov pa roj carbon.Qhov siab dua cov ntsiab lus carbon, qhov ntau dua lub zog ntawm cov khoom.Cov tom kawg yog siv rau cov motors.Ntxiv nrog rau cov lus hais saum toj no, cam khwb cia Carbon kuj tseem siv tau rau lwm lub hom phiaj.Cov khoom siv hluav taws xob ntawm Carbon steel yog rhiab heev rau qhov kub thiab txias.Thaum lub sij hawm kub siab, cov khoom ntawm cov khoom siv kho tshuab degrade thiab nws ua rau tsis ua hauj lwm ntxov.Tsis tas li ntawd, cov hlau yog nquag oxidation, hydrogen puas, carbide instability thiab sulphite scaling.Nws toughness yog heev txo nyob rau hauv qis kub.Yog li ntawd, tshwj xeeb Low-temperature Steel yog muaj los daws cov teeb meem no.Cov ntsiab lus alloying nce lub toughness ntawm carbon steel casting.
