Hom Si Target hauv HSLA
0.15-0.35% yog '(nws txawv ntawm qib)
FeSi72 tso cai rau kev ua tiav ntawm qhov ntau yam tsis muaj kev pheej hmoo ntawm kev sib tw, uas tuaj yeem cuam tshuam kev weldability lossis formability.
Txheej txheem kev koom ua ke
Ntxiv theem: Feem ntau hauvladleTom qab tapping los ntawm EAF lossis BOF.
Kev suav tshuaj: Raws li pib yaj O thiab lub hom phiaj Si; Piv txwv li, nce Si los ntawm 0.05% mus rau 0.25% hauv 100 t cua sov:
Si xav tau=(0.25−0.05)%×100t=200kg Si
FeSi 72=0.72200≈278kg
Sib tovUa kom zoo sib xws ua ntej casting.
Cov txiaj ntsig hauv HSLA
Txhim kho lub zog - rau - qhov hnyav pivntawm Si strengthening.
Zoo dua toughnesslos ntawm finer grain qauv.
Cov hlau huv huvnrog tsawg inclusions → enhanced qaug zog kuj.
