Txoj kev tsim khoom:
Npaj cov ntshiab aluminium ingots, aluminium tsawg lub ntiaj teb alloy ingots, potassium fluorotitanate, potassium fluoroborate thiab lwm yam ntaub ntawv raw raws li cov khoom xyaw ua ntej npaj refiner;Thaum tshav kub kub thiab yaj aluminium ingots thiab txhuas tsis tshua muaj lub ntiaj teb ingots nyob rau hauv ib tug nruab nrab zaus induction rauv, thiab ces ntxiv ntau yam raw khoom;Lub yaj pib ua rau lub siab kub;Tom qab cov tshuaj tiv thaiv tiav, kev txuag hluav taws xob thiab kev tshem tawm slag tiav, thiab tom qab ntawd nws tau muab pov rau hauv ib qho ingot los yog nruam nruam thiab dov rau hauv ib lub pas hlau.Raws li cov txheej txheem saum toj no, rau high-purity aluminium, columnar crystals yuav raug tshem tawm.Rau kev lag luam ntshiab txhuas thiab ntau yam ntawm deformed aluminium alloys, cov nplej loj tuaj yeem ua kom zoo dua li 100 μm.Nws tuaj yeem txo qis kom qis dua 2μm;rau Al-Si alloy, cov nplej loj tuaj yeem ua kom zoo rau hauv qab 150-200μm.Nyob rau tib lub sijhawm, lub zog, plasticity thiab toughness ntawm kev lag luam ntshiab aluminium thiab ntau yam aluminium alloys tau zoo dua.Khoom taw qhia: Nta: refinement, yooj yim rau siv, rau aluminium alloy melt.
Siv txoj kev:
Nws tau siv sab nraum lubrauv, thaum lub txhuas dej tso tawm, ncaj qha ntxig rau txhuas titanium boron hlau rau hauv ceramic ntxhua khaub ncawsdhau ntawmfeederkom yaj thiab ua kom zoo, thiab xyuas kom meej tias cov txhuas titanium boron hlau thiab txhuas cov dej nyob rau hauv kev sib cuag rau ntau tshaj 1 feeb (nyiam dua 2-10 feeb).Qhov ntau npaum li cas0.8-1.3kg / tonntawm aluminium (txoj kab uas hla ntawm aluminium-titanium-boron hlau yog9.5mm ib, thiab qhov hnyav yog0.192kg / m).
Txog Φ9.5mm hlau,Txhua yob yog hais txog 100 kg (170 kg), alloy hlau muaj pes tsawg leeg yog 5% T 1% B, Cov ntsiab lus ntawm cov khoom xyaw thiab impurities ua tau raws li cov kev cai ntawm lub teb chaws tus qauv GB8736-88.
