Qhov txawv ntawm Silicon thiab Ferrosilicon yog dab tsi?
Hlau silicon thiab ferrosilicon yog yam txawv. Cov txheej txheem ntau lawm zoo ib yam, tab sis cov qauv siv sib txawv, thiab cov khoom siv kuj sib txawv. Qhov taw qhia nyuaj-rau-tswj hauv cov xim hlau silicon yog cov ntsiab lus hlau, thaum ferrosilicon kuj yooj yim, nrog ib tus ntiv tes. Nyob rau hauv cov nqe lus ntawm raw cov ntaub ntawv, ferrosilicon kuj yuav siv tau raws li ib tug alloying neeg sawv cev nyob rau hauv steelmaking.
Ntxiv qee qhov nyiaj ntawm silicon rau cov hlau tuaj yeem txhim kho lub zog, hardness thiab elasticity ntawm cov hlau, ua kom cov hlau nplaum permeability ntawm cov hlau, thiab txo cov hysteresis poob ntawm transformer steel.
Nws yog dav siv nyob rau hauv qis alloy structural steel, bonded steel, caij nplooj ntoos hlav steel, bearing steel, kub-resistant steel thiab hluav taws xob silicon steel. Nws feem ntau yog siv los tsim ib qho siv lead ua silicon lossis npaj cov hlau tsis muaj hlau.
Thermal conductivity ntawm steel: High thermal conductivity tuaj yeem txo cov cua sov ntawm cov hlau ntawm cov pwm, yog li txo cov thermal qaug zog ntawm cov hlau.
Nws yog feem ntau ntseeg tias thermal conductivity ntawm hlau muaj feem xyuam rau cov ntsiab lus carbon. Thaum cov ntsiab lus carbon siab, thermal conductivity tsawg. Thaum cov ntsiab lus carbon tsawg dhau, qhov hardness thiab lub zog ntawm cov hlau yuav txo qis. Yog li ntawd, nruab nrab carbon steel feem ntau yog siv los ua haujlwm kub pwm hauv kev tsim khoom.
Kev cuam tshuam ntawm cov ntsiab lus tseem ceeb ntawm cov hlau: Feem ntau, qhov siab dua qhov tseem ceeb ntawm cov hlau, qhov qis dua thermal qaug zog ntawm cov hlau. Yog li ntawd, lub thermal qaug zog tsis kam ntawm lub mesh feem ntau txhim kho los ntawm kev ntxiv cov ntsiab lus hlau Cr, W, thiab Si kom nce qhov tseem ceeb ntawm cov mesh.
Vim tias qhov ua haujlwm kub thiab cov khoom thauj khoom sib txawv, thiab nws tsis tuaj yeem ua rau txhua yam pwm hlau kom muaj lub zog thermal, hnav tsis kam, tawg tsis kam, thermal qaug zog, thiab lwm yam tib lub sijhawm.
Thaum xaiv, peb tsuas tuaj yeem tsom mus rau qhov tseem ceeb ntawm kev ua haujlwm ntawm pwm kom ntseeg tau qhov tseem ceeb, thiab tom qab ntawd xaiv cov khoom siv coj los siv rau lwm yam khoom.
