Siab zooaluminium ingotntau lawm billet yuav tsum tsis muaj qhov tseem ceeb xoob, porosity, thiab cov ntsiab lus tsawg ntawm hydrogen thiab oxidation suav nrog, nplua nplej. Txhawm rau ua kom zoo tshaj qhov kev faib tawm ntawm cov theem diffusion tom qab alloy qhov nruab nrab, ob-theem nruab nrab txheej txheem ntawm qhov kub thiab txias tuaj yeem siv tau. Tom qab ob-theem nruab nrab, cov dispersion hais nyob rau hauv lub alloy yog ntau tusyees faib thiab zoo. Lub zog siab aluminium alloy muaj qhov dav crystallization ntau thiab muaj kev nyiam ntau dua ntawm eutectic cracking thaum lub sij hawm tsis sib npaug.
Melt electromagnetic stirring thev naus laus zis yog los tsim hluav taws xob hluav taws xob hauv lub pas dej ua ke aluminium, do cov kev ua ntawm txhuas yaj hauv lub pas dej molten, ua kom cov yaj muaj pes tsawg leeg, tsis txhob muaj kuab paug ntawm cov cuab yeej hlau thaum phau ntawv stirring. Hydraulic semi-nruab nrab forging tshuab yog siv rau forging, uas muaj cov yam ntxwv ntawm kev ruaj khov, siab automation thiab siab tswj qhov tseeb. Qhov kawg ua haujlwm ntawm aviation aluminium ingot yog ze rau nws cov qauv.
Yog li ntawd, tsis muaj tawg loj ingot forging yog ib tug loj specification ntawm cov ntaub ntawv ntau lawm yuav tsum tau los daws cov hub poob. Vim cam khwb cia ingot dimension yog loj, lub tshav kub kev nyuaj siab ntawm contraction yog loj, EASY craze. Yuav kom forge loj tawg dawb ingot nrog siab zoo, ib tug series ntawm melting thiab casting technologies tau tsim. Melt electromagnetic stirring yog ib qho tseem ceeb tshaj plaws tshiab technologies. Vim yog cov ntsiab lus siab ntawm cov ntsiab lus tseem ceeb hauv cov hlau, lub zog siab aluminium alloy yog ib qho yooj yim los tsim kev sib cais hauv cov yaj, nyuaj rau faib tusyees, thiab cov nucleation tus nqi txo, cov nplej loj yog ntxhib. Nyob rau tib lub sij hawm, lub ingot billet tau kuaj los ntawm ultrasonic flaw nrhiav kom tau inclusions, tawg, pores thiab lwm yam tsis xws luag. Ntxiv nrog rau cov ntsiab lus hydrogen, qee cov alkali hlau Li, Na, K thiab alkaline ntiaj teb hlau Ca kuj yuav tsum tau tswj nruj me ntsis.
Loj dav thickness ingot yog ib qho yooj yim rau tawg thaum lub sij hawm forging. Kev tswj ruaj khov ntawm cov txheej txheem forging yog qhov tseem ceeb heev rau kev tsim cov txhuas ingot. Qhov kev kho mob nruab nrab tuaj yeem ua rau cov hlau sib xyaw sib npaug sib npaug, tshem tawm qhov tsis sib npaug ntawm crystallization qis melting point theem, spheroidize lub zog thib ob theem, tsim ib coherent dispersion theem rau cov txheej txheem tom ntej los tswj cov qauv ntawm cov khoom, txo cov quenching rhiab heev ntawm cov hlau, txhim kho lub zog thiab toughness ntawm cov khoom rau cov ntaub so ntswg npaj.
