Aluminium nroj tsuag xaiv silicon cores graded los ntawm purity thiab qib. Ntau hom (xws li 553 #, 441 #, 3303 #, thiab 95% -99.5% purity qib) yog tsim rau cov kev xav tau sib txawv hauv aluminium alloy ntau lawm, xws li deoxidation, alloying, thiab casting optimization. Kev xaiv meej ncaj qha cuam tshuam rau kev ua haujlwm thiab cov nqi tsim khoom ntawm aluminium alloys.
Kev faib tawm thiab cov yam ntxwv ntawm feem ntau siv Silicon Cores hauv Aluminium Cog
| Hom ntawm silicon hlau (Hom) | Qib sib thooj (Qib) | Silicon cov ntsiab lus (Si Ntau dua lossis sib npaug) | Tag nrho impurities (Fe + Al + Ca Tsawg dua lossis sib npaug) | Core Adaptation Scenarios |
|---|---|---|---|---|
| Siab - hom purity | 3303#,2202# | 99.5%,99.7% | 0.63%,0.42% | High-kawg aluminium alloys, precision casting |
| Nruab nrab -purity hom | 441#,421# | 99.0%,99.2% | 0.9%,0.7% | Cov pa cam khwb cia aluminium alloys, wrought aluminium alloys |
| General - hom phiaj | 553# | 98.5% | 1.3% | Ordinary aluminium alloys, deoxidation ntawm molten aluminium |
| Hom kev lag luam | 97%, 95% purity | 97%,95% | 3.0%,5.0% | Tsawg-yuav tsum tau castings, silicon recycled aluminium |
Nco tseg:Cov ntsiab lus impurity ncaj qha cuam tshuam rau kev ua tau zoo ntawm aluminium alloy-Fe yooj yim ua rau txhuas dub thiab txo cov yas; Al (ib qho impurity nyob rau hauv silicon) yooj yim tsim nyuaj thiab nkig inclusions; Ca tau yooj yim cuam tshuam cov dej ntws. High-kawg aluminium alloys xav tau kev tswj hwm nruj dua li peb lub ntsiab lus.
Core Functions thiab Quantitative Effects ntawm Silicon hlau feem ntau siv nyob rau hauv Aluminium Cog
(1) Alloying Strengthening: Txhim kho cov cuab yeej cuab tam ntawm Aluminium Alloys
Mechanism of Action: Silicon atoms integrate rau hauv aluminium matrix los tsim ib qho kev daws teeb meem, los yog tsim cov theem ntxiv (xws li Mg₂Si) nrog magnesium, tooj liab, thiab lwm yam, cuam tshuam kev txav mus los thiab txhim kho lub zog thiab hardness;
(2) Casting Performance Optimization: Txhim kho Flowability thiab tsim cov nyhuv
Mechanism of Action: Silicon txo qhov melting point ntawm aluminium alloys (ntshiab aluminium melting point 660 degree, Al-12Si alloy melting point 577 degree), txo cov solidification shrinkage kev nyuaj siab, thiab txhim kho cov flowability ntawm cov hlau molten;
(3) Aluminium Molten Hlau Deoxidation thiab Purification: Txhim kho cov purity ntawm txhuas cov ntaub ntawv
Mechanism of Action: Silicon reacts nrog oxygen hauv aluminium molten hlau los tsim SiO₂ (density 2.65g / cm³), uas yog qis dua li ntawm aluminium molten hlau (2.7g / cm³), thiab yooj yim floated rau daim slag rau kev tshem tawm;
(4) Silicon Supplementation nyob rau hauv Recycled Aluminium: Regulates Composition Stability
Mechanism of Action: Silicon cov ntsiab lus tau yooj yim hlawv tawm thaum lub sij hawm smelting ntawm recycled txhuas. silicon hlau, raws li ib tug "silicon ntxiv tus neeg sawv cev," kom yog replenishes cov ntsiab lus ntawm silicon, kom ntseeg tau qhov sib xws ntawm alloy kev ua tau zoo;
