Dab tsi yog calcium silicon alloys siv rau hauv steel

Calcium-silicon alloys ua lub luag haujlwm tseem ceeb hauv kev tsim cov hlau. Lawv yog siv rau:
Calcium-silicon alloys yog siv los tshem tawm impurities ntawm hlau. Silicon thiab calcium nyob rau hauv calcium-silicon alloys muaj zog khi rau oxygen thiab sulfur. Cov khoom ntab yooj yim rau saum npoo, txhim kho cov hlau thiab ua kom yooj yim dua thiab ruaj khov. Calcium-silicon alloys ua haujlwm zoo heev ntawm kev tshem tawm impurities. Calcium-silicon alloy tuaj yeem hloov pauv aluminium raws li qhov kawg deoxidizer thiab siv hauv steel ntau lawm. Calcium-silicon alloy yog xav tau rau deoxidation hauv nruam casting.
(2) Calcium-silicon alloy nce qhov kub thiab txias. Ntxiv calcium-silicon alloy hmoov rau cov hlau ingot txhim kho cov khoom zoo thiab tawm los.
(3) Calcium-silicon alloy yog siv los tshem tawm impurities ntawm cam khwb cia hlau. Calcium-silicon alloy txhim kho qhov zoo ntawm cam khwb cia hlau zoo dua ferrosilicon. Calcium-silicon alloy tuaj yeem deoxidize, dephosphorize thiab nce cov ntsiab lus ntawm silicon ntawm cam khwb cia hlau. Nws kuj pab tsim cov nodular graphite. Txhawm rau kom tau txais txiaj ntsig zoo tshaj plaws ntawm calcium-silicon alloy, xyuas kom meej tias qhov loj me yog li 2 hli.
