Lub luag haujlwm hauv Kev Lag Luam Cast Iron

Inoculants thiab spheroidizers. cam khwb cia hlau yog cov khoom siv hlau tseem ceeb hauv kev lag luam niaj hnub no, uas yog pheej yig dua li cov hlau, yooj yim rau yaj thiab smelt, thiab muaj kev ua haujlwm zoo tshaj plaws thiab zoo dua seismic tsis kam tshaj hlau. Tshwj xeeb tshaj yog nodular cam khwb cia hlau, nws cov cuab yeej cuab tam ncav cuag los yog mus kom ze rau cov khoom siv hlau. Ntxiv ib qho nyiaj ntawm ferrosilicon rau cam khwb cia hlau tuaj yeem tiv thaiv kev tsim cov carbides thiab txhawb cov nag lossis daus thiab spheroidization ntawm graphite. Yog li ntawd, ferrosilicon yog ib qho tseem ceeb inoculant (pab kom precipitate graphite) thiab spheroidizing tus neeg sawv cev nyob rau hauv zus tau tej cov ductile hlau.
