Metallographic qauv
Cov khoom siv ntawm 15nicumonb 5-6-4 samless steel raj (diwa373, WB36) steel yog dab tsi (quenching) + tempering. Tom qab kev kho cua sov kawg ntawm ib txwm ua thiab tempering, microstructure yog bainite + ferrite + sorbite + sorbite + me ntsis ntawm ferrite.
Vuam cov khoom siv
15nicumonb {5-6-4 Cov leeg txheej txheem muaj kev ua haujlwm vuam ua tau zoo. Kev tuav cov ntaub ntawv vuam lod L {2}} (aw-e11016g), aws-e110s) lossis coj mus rau cov ntaub ntawv vuam. Txhawm rau kom tsis txhob vuam tawg, preheating (kub {8}} degree) yuav tsum tau nqa tawm ua ntej vuam. Kev kho mob ntxhov siab lug yuav tsum nqa tawm tom qab vuam.
W36 ua nyob rau hauv Suav teb muaj zoo weldability thiab high in rhiab tawg los ntawm preheating txias ntawm 150 degree, thiab nws tsis rhiab txog kev rov ua kom rov qab tawg. Kev tuav Arc Vuam nrog Vuam Rod Che607NI Rov Qab H10MN2Moa Vuam Hlau Thiab Sj101 Flux Submerged Arc Vuam Vuam. Tom qab {{8} degree post weld kev kho cua sov, nws muaj kev ua tau zoo thiab tuaj yeem ntsib kev tsim khoom.
