High-carbon ferrosilicon yog ib qho khoom siv tshiab tsim los siv rau hauv kev hloov pauv. Nws yog ib qho kev hloov pauv rau ferrosilicon, silicon carbide, thiab carburezer, thiab yog siv rau hauv cov txheej txheem smelting ntawm converters. Qhov no alloy ua tau zoo, yielding zoo dua hlau piv rau cov pa txoj kev. Tsis tas li ntawd, nws tuaj yeem ua haujlwm los tsim cov khoom siv dav dav, alloy, thiab cov hlau tshwj xeeb, thiab tuaj yeem siv qhov chaw ntawm cov khoom siv hluav taws xob ntau dua hauv kev hloov pauv thiab qhib-hearth steel ntau lawm.
High-carbon ferrosilicon yog dav siv deoxidizer nrog ntau yam txiaj ntsig:
Nws tsis tsim hydrogen thaum lub sij hawm deoxidation txheej txheem, uas txhim kho kev nyab xeeb thiab kev ntseeg tau. Cov pa roj carbon thiab silicon yog cov khoom tseem ceeb rau kev tsim cov hlau. High-carbon ferrosilicon cuam tshuam nrog oxygen hauv cov hlau molten kom tshem tawm cov impurities, thaum cov pa roj carbon monoxide thiab silicon tuaj yeem ua ke rau hauv cov hlau molten los txhawb nws cov qib carbon thiab silicon. Yuav kom tswj tau qhov zoo, steel yuav tsum tau deoxidation. Silicon ua lub zog deoxidizer, txhim kho lub zog, hardness, thiab elasticity ntawm cov hlau.
