Calcium-silicon alloys ua lub luag haujlwm tseem ceeb hauv kev lag luam steel. Lawv feem ntau yog siv rau:
(1) Calcium-silicon alloys yog siv los ua deoxidizers thiab desulfurizers hauv kev lag luam steel. Silicon thiab calcium nyob rau hauv calcium-silicon alloys muaj ib tug muaj zog affinity rau oxygen, thiab calcium kuj muaj ib tug muaj zog affinity rau sulfur. Deoxidation thiab desulfurization cov khoom ntab yooj yim rau saum npoo, txhim kho cov khoom ntawm cov hlau thiab nce nws cov ductility thiab toughness. Yog li ntawd, calcium-silicon alloys yog ib qho zoo heev deoxidizer. Tam sim no, calcium-silicon alloy tuaj yeem hloov pauv aluminium raws li qhov kawg deoxidizer thiab tau siv dav hauv cov hlau ntau lawm. Calcium-silicon alloy tseem xav tau rau deoxidation hauv nruam casting.
(2) Calcium-silicon alloy tuaj yeem siv los ua ib txoj hauv kev zoo kom nce qhov kub thiab txias. Ntxiv calcium-silicon alloy hmoov rau cov hlau ingot taub hau ua tus neeg sawv cev cua sov tuaj yeem txhim kho cov hlau zoo thiab cov txiaj ntsig ntawm qhov zoo.
(3) Calcium-silicon alloy yog siv los ua deoxidizer thiab desulfurizer hauv kev tsim cov hlau cam. Calcium-silicon alloy muaj txiaj ntsig zoo dua li ferrosilicon hauv kev txhim kho cov khoom ntawm cam khwb cia hlau. Calcium-silicon alloy tuaj yeem deoxidize, dephosphorize thiab nce cov ntsiab lus ntawm silicon ntawm cam khwb cia hlau, thiab yog ib qho zoo inoculant uas txhawb kev tsim ntawm nodular graphite. Nyob rau hauv qhov tseeb ib puag ncig, thiaj li yuav ua kom zoo siv lub luag hauj lwm ntawm calcium-silicon alloy, particle loj ntawm lub alloy yuav tsum yog hais txog 2 hli, thiab nws yuav tsum tau ntxiv ncaj qha mus rau lub molten hlau tank, npua hlau sib tov rauv los yog molten hlau. ladle.
