Aluminium alloy manufacturers feem ntau ntsib qhov mob tseem ceeb: cov khoom siv silicon hlau dhau los kuaj cov tshuaj muaj pes tsawg leeg, tab sis cov khoom tsim los yog cov ntaub ntawv rov ua dua cov teeb meem xws li lub zog hloov pauv, qhov tsis xws luag, lossis kev ua haujlwm tsis zoo. Lub hauv paus ua rau yog tias tsuas yog ua tau raws li cov qauv thoob ntiaj teb (xws li Si Ntau dua lossis sib npaug li 98.5%) tsis txaus. Lub microstructure thiab kev faib tawm ntawm cov teeb meem impurity (Fe, Ca, Al) muaj kev txiav txim siab rau qhov kawg alloy qhov kev ua tau zoo.

Tus nqi tseem ceeb ntawm silicon nyob rau hauv aluminium alloys nyob rau hauv nws lub hom phiaj "impurity tswj pob":

Hlau (Fe):Cov hlau ntau dhau los yog tsis raug xa tawm tuaj yeem ua rau ntxhib, rab koob-zoo li lossis Suav cim- zoo li -FeSiAl₅ theem, ua rau cov ntsiab lus kev ntxhov siab thiab ua rau cov hlau tsis muaj zog, qaug zog, thiab ua kom tiav.

Calcium (Ca):Nws yooj yim tsim tsawg- melting- taw tes eutectics nrog txhuas thiab silicon, ua kom yaj viscosity, ua rau txo qis casting fluidity, thiab tej zaum yuav ua rau cov pob tawv tawv uas ua rau pwm hnyav dua.

Aluminium (Al):Raws li ib qho los ntawm - cov khoom lag luam, nws cov ntsiab lus cuam tshuam rau nucleation thiab kev loj hlob ntawm silicon theem; cov ntsiab lus ntawm aluminium tsis ruaj khov tuaj yeem ua rau batch-rau-batch kev hloov pauv.

Tsis zoo liferrosilicon(uas muaj cov hlau siab), qhov tshwj xeeb hlau silicon no txo qis impurity - vim qhov tsis xws luag (piv txwv li, Fe-Al-Si nkig theem), ua kom muaj kev ua haujlwm ntawm aluminium alloy.

Khoom Description

Q: Kuv yuav ua li cas yog tias cov ntsiab lus hlau ntau dua tus qauv thaum siv 441 silicon hlau hauv ADC12 smelting txheej txheem?

A: Qhov no feem ntau tshwm sim los ntawm ob qho laj thawj: Ua ntej, cov ntsiab lus hlau ntawm silicon hlau nws tus kheej tsis ruaj khov, qhia txog qhov tseem ceeb ntawm kev xaiv tus neeg muag khoom nrog kev tswj xyuas nruj zoo li AON Hlau; Thib ob, hlau paug los ntawm lub tshuab ua cua sov hauv ob sab phlu, cov cuab yeej, lossis cov khoom seem thaum lub sij hawm smelting. Peb pom zoo ua ntej kuaj cov ntshiab silicon hlau raw cov ntaub ntawv nkag mus rau hauv lub qhov cub kom paub qhov chaw ntawm qhov teeb meem. Nyob rau tib lub sijhawm, ua kom zoo dua cov txheej txheem smelting thiab tsis txhob sib zog ntau dhau ntawm qhov siab -kub molten aluminium siv cov cuab yeej hlau.

Q: Peb tab tom tsim A356 lub log siv 3303 silicon hlau thiab strontium modifiers, tab sis qhov kev hloov kho tsis zoo. Yuav ua li cas yog vim li cas?

A:Dhau li ntawm kev ua kom cov hlau silicon muaj cov ntsiab lus calcium tsawg (Ca Less dua lossis sib npaug li 0.03%), cov hauv qab no kuj yuav tsum tau sau tseg: 1) Melting kub thiab tswm ciab: Qhov kev hloov kho kub feem ntau yog 720-740 degree, thiab lub sij hawm txaus yuav tsum tau tso cai rau strontium faib tusyees; 2) Phosphorus (P) cov ntsiab lus hauv cov yaj: Phosphorus tuaj yeem "tshuaj lom" kev hloov pauv ntawm strontium, yog li nws yog ib qho tsim nyog los xyuas kom meej tias cov ntsiab lus phosphorus ntawm thawj lossis rov siv dua txhuas cov ntaub ntawv siv yog tsawg heev.

Q: Dab tsi yog qhov kev coj ua zoo tshaj plaws rau lub sijhawm thiab cov txheej txheem ntawm kev ntxiv silicon hlau?

A: Lub sijhawm zoo tshaj yog ntxiv nws thaum cov kua txhuas yog yaj tag thiab nce mus txog 730 degree. Nws raug nquahu kom ntxiv nws rau hauv cov khoom sib xyaw nrog kev nplawm kom ntseeg tau tias muaj kev sib xyaw ua tiav thiab sib xyaw ua ke. Rau granular silicon, nws tuaj yeem muab ntxiv tom qab hauv cov txheej txheem melting siv lub tshuab pub mis tsis siv neeg, uas muaj txiaj ntsig zoo dua. Tsis txhob ntxiv cov khoom loj ntawm silicon ncaj qha rau saum npoo ntawm cov kua txhuas ntawm qhov kub thiab txias, vim qhov no yuav ua rau kub hnyiab heev - tawm thiab tsis sib xws.
