Dab tsi yog lub luag haujlwm tseem ceeb ntawm Silicon Hlau hauv Aluminium Alloy Production?
Silicon hlau yog thawj alloying thiab txheej txheem - tswj lub hauv paus ntawm aluminium manufacturing, feem ntau ntxiv nyob rau hauv ntau yam2%–25% Si nyob ntawm qib alloy (piv txwv li, ADC12, A356, Al-Si casting alloys). Nws txhim khofluidity, txo shrinkage, txhim khu kev hnav tsis kam, thiab stabilizes casting kev ua tau zoo ntawm melting kub nyob ib ncig ntawm 660-750 degree.
Peb muab kev lag luam silicon hlau hauv0-10mm, 10-50mm, 50-100mm, thiab customized pob loj, nrog purity qib mus txog99.0% – 99.5% Si, optimized rau aluminium alloy ntau lawm sib xws thiab yaj efficiency.
Vim li cas Silicon hlau siv hauv Aluminium Alloy Manufacturing?
Silicon hlau yog siv nyob rau hauv aluminium alloy manufacturing vim nws fundamentally hloov tus cwj pwm ntawm molten aluminium. Yog tsis muaj silicon, aluminium melts yog qhov ua rau tsis zoo castability, siab shrinkage defects, thiab tsis ruaj khov.
Nyob rau hauv industrial casting systems, silicon ua raws li ib tugeutectic hloov kho, txo qhov melting point ntawm aluminium alloys (los ntawm ntshiab Al ~ 660℃mus rau ~ 577℃hauv Al-Si eutectic systems). Qhov no txhim kho ntws mus rau hauv cov pwm geometries thiab txo cov porosity tsim thaum lub caij txias.
Los ntawm txoj kev tsim khoom, silicon hlau tsis yog ib qho khoom ntxiv xwb - nws yog ib qhotxheej txheem stability khoomuas ncaj qha txiav txim siab npaum li cas, qhov sib piv, thiab qhov kawg ntawm kev ua haujlwm zoo sib xws hauv automotive, aerospace, thiab tuag-casting applications.

Yuav ua li cas Silicon hlau txhim kho Aluminium Alloy Casting Performance?
Silicon hlau ho txhim kho txhuas casting tus cwj pwm nyob rau hauv peb txoj kev metallurgical tseem ceeb.
Ua ntej, nws txhim khofluidity ntawm molten aluminium, tso cai rau cov hlau ua kom nyias nyias -phab ntsa thiab cov kab noj hniav nyuaj uas tsis muaj qhov ua tsis tiav casting. Qhov no tseem ceeb heev nyob rau hauv automotive engine blocks thiab gearbox vaj tse.
Qhov thib ob, nws txosolidification shrinkage, uas ncaj qha minimizes internal voids thiab porosity. Nyob rau hauv cov nqe lus ntawm ntau lawm, qhov no nce yield tus nqi thiab txo downstream machining pov tseg.
Thib peb, silicon stabilizes lubAl-Si eutectic microstructure, uas txhim kho qhov ruaj khov ntawm qhov ntev thiab txo qhov kev sib tsoo thaum lub sij hawm thermal cycling.
Nyob rau hauv industrial foundries, txawm a1% kev hloov pauv hauv cov ntsiab lus silicon tuaj yeem pom muaj feem cuam tshuam rau qhov tsis xws luag, ua kev tswj silicon hlau ntxiv ib qho tseem ceeb zoo lever.
