Hlau silicon 3303yog ib qho khoom siv ntau yam ntxiv thiab txhim kho hauv kev tsim khoom aluminium. Nws tuaj yeem txhim kho lub cev thiab tshuaj lom neeg zoo ntawm aluminium alloys, txhim kho kev tsim khoom thiab cov khoom zoo, yog li nws muaj ntau daim ntawv thov thiab qhov tseem ceeb hauv kev lag luam aluminium alloy.
Tshuaj muaj pes tsawg leeg:
| Qib | Si | Fe | Al | Ca | P |
| 3303 | 99.37% | 0.3% | 0.3% | 0.03% | <=0.005% |
Nws feem ntau ua lub luag haujlwm hauv qab no:
Deoxidizer thiab desulfurizer:Silicon hlau 3303 yog siv los ua adeoxidizernyob rau hauv cov txheej txheem aluminium smelting los pab tshem tawm cov pa oxygen thiab lwm yam oxides los ntawm txhuas yaj. Qhov no yog vim hais tias silicon tuaj yeem tsim SiO₂ nrog oxygen, yog li txo cov pa oxygen thiab tshem tawm ntawm cov yaj, txo cov pa seem thiab txhim kho cov purity thiab zoo ntawm txhuas. Tsis tas li ntawd, silicon kuj muaj qee yam desulfurization nyhuv, pab txo cov sulfur ntsiab lus hauv aluminium alloys.
Alloy additives:Silicon 3303 yogntxiv rau aluminium alloyslos txhim kho cov khoom siv ntawm cov hlau, xws li lub zog tensile, hardness thiab hnav tsis kam. Silicon tsim ib qho kev daws teeb meem hauv aluminium alloys, ntxiv dag zog rau cov qauv lattice ntawm cov hlau, thiab txhim kho nws lub zog tensile thiab qaug zog, ua rau nws haum rau cov ntawv thov uas xav tau lub zog siab.
Grain refiner:Si 3303 kuj tseem siv tau los ua cov khoom siv nplej kom txo tau cov nplej loj ntawm txhuas alloys. Grain refinement pab ua kom lub zog thiab plasticity ntawm cov hlau, thiab tuaj yeem txhim kho cov khoom ua haujlwm thiab corrosion kuj ntawm alloy.
Thaum tshav kub kub kuj thiab corrosion kuj:Cov khoom siv ntxiv dag zog rau cov nyhuv ntawm silicon tuaj yeem txhim kho kev ruaj ntseg thiab ua haujlwm ntev ntawm aluminium alloys nyob rau hauv qhov kub thiab txias thiab corrosive ib puag ncig, ua rau nws tsim nyog rau kev siv nyob rau hauv industrial teb uas yuav tsum tau kub kub thiab corrosion kuj.
