Dab tsi yog lub luag haujlwm ntawm silicon calcium alloy hauv kev lag luam steel?
Silicon calcium alloy plays lub luag haujlwm tseem ceeb hauv kev lag luam steel. Nws feem ntau yog siv rau:
(1) Silicon calcium alloy yog siv los ua deoxidizer thiab desulfurizer hauv kev lag luam steelmaking. Silicon thiab calcium nyob rau hauv silicon calcium alloy muaj ib tug muaj zog affinity rau oxygen, thiab calcium muaj ib tug muaj zog affinity rau sulfur. Cov khoom deoxidation thiab desulfurization tuaj yeem yooj yim ntab thiab tshem tawm, txhim kho kev ua haujlwm ntawm cov hlau thiab ua rau nws cov plasticity thiab cuam tshuam toughness. Yog li ntawd, silicon calcium alloy yog ib tug zoo composite deoxidizer. Tam sim no, silicon calcium alloy tuaj yeem hloov pauv aluminium kawg deoxidation thiab yog siv dav hauv steel ntau lawm. Nruam casting tseem yuav tsum tau silicon calcium alloy deoxidation.
(2) Silicon calcium alloy tuaj yeem siv los ua cov khoom ua kom sov. Ntxiv silicon calcium alloy hmoov rau lub taub hau ntawm cov hlau ingot ua tus neeg sawv cev cua sov tuaj yeem txhim kho cov hlau zoo thiab cov txiaj ntsig tau zoo.
(3) Silicon calcium alloy yog siv los ua deoxidizing, desulfurizing thiab inoculant hauv cam khwb cia hlau ntau lawm. Silicon calcium alloy txhim kho kev ua haujlwm ntawm cam khwb cia hlau zoo dua ferrosilicon. Silicon calcium alloy tuaj yeem deoxidize, deoxidize thiab nce silicon hauv cam khwb cia hlau, thiab nws kuj yog ib qho zoo inoculant los txhawb kev tsim ntawm spheroidal graphite. Hauv kev siv tiag tiag, txhawm rau ua kom zoo dua lub luag haujlwm ntawm silicon calcium alloy, qhov loj me ntawm cov hlau yuav tsum yog li 2 hli, thiab nws yuav tsum tau ntxiv ncaj qha rau cov hlau ntws trough, hlau sib tov rauv lossis hlau ladle.
