Dab tsi yog kev siv ntawm silicon calcium alloy?
Silicon calcium alloy yog ib yam tshiab ntawm ferroalloy khoom. Silicon calcium alloy yog kev sib xyaw ntawm silicon thiab calcium. Nws muaj zog deoxidation nyhuv hauv cov txheej txheem steelmaking. Vim tias nws muaj kev sib raug zoo nrog cov pa oxygen, cov hlau molten raug txo rau tib lub sijhawm. Yog tias tsis muaj txaws, lub caij nyoog ntawm cov neeg ua haujlwm raug scalded yuav raug txo kom tsawg,
Kev siv cov khoom siv silicon hauv silicon calcium alloy:
Silicon yog cov khoom qub uas muaj ntau yam kev siv, tab sis hauv silicon calcium alloy, peb tsuas yog siv dav hauv kev lag luam steelmaking. Cov khoom siv silicon hauv silicon calcium alloy tuaj yeem txo cov hlau molten zoo heev thiab muaj cov neeg ua haujlwm txo qis, vim tias yuav muaj cov pa ntau hauv cov hlau molten thaum lub sij hawm steelmaking. Yog tias muaj cov pa oxygen ntau dhau, yuav muaj ntau cov oxides uas cuam tshuam rau qhov zoo ntawm cov hlau. Silicon calcium alloy tuaj yeem tshem tawm cov pa tawm sai sai los ntawm cov hlau los tsim cov silicon dioxide, yog li nws muaj peev xwm ua kom huv huv cov hlau molten los txhim kho cov hlau zoo.
Kev siv cov calcium hauv silicon calcium alloy:
Calcium yog ib qho tseem ceeb hauv kev tsim cov hlau. Nws lub hom phiaj tseem ceeb yog txhawm rau txhim kho qhov fluidity ntawm molten steel thiab txhim kho lub zog thiab txiav kev ua tiav ntawm cov hlau tiav. Kev siv cov calcium silicon alloy tuaj yeem tiv thaiv lub qhov ncauj los ntawm kev thaiv, kom cov impurities hauv cov hlau molten tuaj yeem ua haujlwm zoo dua. Cov dej ntws zoo txhim kho kev ua haujlwm ntawm cov hlau tiav.
Lwm yam kev siv ntawm calcium silicon alloy:
Silicon calcium alloy tseem siv los tsim cov hlau thiab cov khoom tshwj xeeb steel. Nyob rau tib lub sijhawm, silicon calcium alloy kuj tseem siv los ua cov khoom siv cua sov, thiab lawv feem ntau siv hauv kev hloov pauv smelting!
