Ua ntej ntawm tag nrho cov, los ntawm kev xav ntawm lub cev muaj zog, qhov ceev ntawm silicon-carbon alloy yog me dua li ntawm cov hlau, tab sis nws hardness yog siab dua hlau, uas qhia cov yam ntxwv ntawm siab zog, siab hardness thiab siab toughness.Tsis tas li ntawd, nws cov hluav taws xob thiab thermal conductivity kuj zoo dua li cov hlau.Cov khoom siv lub cev no muab cov khoom siv silicon-carbon alloys tseem ceeb hauv kev tsim cov cuab yeej carbide, cov khoom siv tshuab tsis siv neeg, thiab cov hlau ceev ceev.
Kev siv ntawm silicon carbon alloy hauv steelmaking
Silicon-carbon alloys ua si ntau lub luag haujlwm tseem ceeb hauv steelmaking.Ua ntej ntawm tag nrho cov, silicon-carbon alloy, raws li ib tug composite deoxidizer, yog tsuas yog siv rau diffusion deoxidation thaum smelting zoo tib yam carbon hlau.Txoj kev deoxidation no tuaj yeem txo lub sijhawm oxygen, yog li txuag lub zog, txhim kho steelmaking efficiency, txo cov khoom siv raw, txo cov pa phem, thiab txhim kho kev ua haujlwm.Tsis tas li ntawd, silicon-carbon alloy kuj muaj cov nyhuv carburizing, uas yog qhov tseem ceeb rau kev txhim kho cov txiaj ntsig zoo ntawm cov hluav taws xob rauv taws.
Thaum lub sij hawm steelmaking txheej txheem, cov khoom silicon nyob rau hauv silicon-carbon alloy reacts nrog oxygen los deoxidize cov pa hauv cov hlau molten thiab txhim kho hardness thiab zoo ntawm cov hlau.Cov tshuaj tiv thaiv no kuj muaj cov yam ntxwv uas molten steel tsis txaws, ua rau cov txheej txheem steelmaking muaj kev nyab xeeb thiab ruaj khov dua.Tib lub sijhawm, silicon-carbon alloy kuj muaj qhov zoo ntawm kev sau slag.Nws tuaj yeem sib sau ua ke cov oxides sai sai hauv cov txheej txheem steelmaking thiab pab kev pom, yog li ua rau cov hlau molten purer thiab zoo heev txhim kho qhov ntom thiab hardness ntawm cov hlau.
