Titanium Extrusion Casting Moulding Technology

Titanium extrusion casting molding tshuab, zoo ib yam li yav dhau los hais txog aluminium alloy extrusion casting, kuj muab faib ua ncaj qha extrusion thiab indirect extrusion ob txoj kev. Vim lub siab melting point ntawm titanium hlau, kev ua ub no, cov khoom siv thiab cov txheej txheem txheej txheem muaj cov kev cai nruj dua.
Direct extrusion casting: nyob rau hauv cov pwm qhib ncaj qha mus rau hauv lub xeev molten ntawm titanium hlau, ua raws li los ntawm ceev ceev ntawm pwm thiab daim ntawv thov kev kub siab, thiaj li hais tias cov titanium hlau nyob rau hauv siab solidification thiab microplastic deformation, thiaj li mus tau ib tug tuab dawb paug. los yog qhov chaw. Txoj kev no yuav tsum muaj kev tswj xyuas nruj ntawm qhov kub thiab txias ntawm cov titanium hlau los tiv thaiv oxidation ntawm cov hlau thiab roj nkag.
Indirect squeeze casting: Lub molten los yog semi-solid titanium hlau yog solidified los ntawm kev siv lub siab los ntawm ib tug punch thiab nias rau hauv lub kaw pwm kab noj hniav. Txoj kev no muab kev tswj xyuas zoo dua ntawm cov dej ntws ntawm cov hlau ua kua thiab cov txheej txheem solidification, txo qhov tsim ntawm qhov tsis xws luag.
Kev tshawb fawb theoretical ntawm titanium hlau nyem casting molding
Nyob rau hauv extrusion casting molding txheej txheem ntawm titanium hlau, siab kuj yog ib qho tseem ceeb tsis tau. Lub siab tsis tsuas yog cuam tshuam rau tus cwj pwm solidification ntawm titanium hlau, tab sis kuj tseem hloov nws cov microstructure thiab txhua yam khoom.

Cov txiaj ntsig ntawm kev ua kom muaj zog ntawm kev coj tus cwj pwm: kev kub siab tuaj yeem txhawb kev sib zog sai ntawm titanium hlau, ua kom zoo dua cov nplej, thiab txhim kho qhov ntom ntom thiab lub zog ntawm cov khoom. Tsis tas li ntawd, lub siab kuj tseem tuaj yeem txo qhov kub thiab txias ntawm titanium hlau, ua kom lub sij hawm solidification.
Kev cuam tshuam ntawm lub siab ntawm microstructure: Nyob rau hauv siab, cov nplej ntawm titanium hlau yuav ua kom zoo dua thiab sib npaug, uas pab txhim kho cov khoom siv dag zog thiab qaug zog ntawm cov khoom.
Qhov cuam tshuam ntawm kev ua haujlwm siab ntawm cov khoom siv kho tshuab: titanium qhov chaw ua los ntawm nyem casting feem ntau muaj lub zog ntau dua thiab muaj zog dua, uas tuaj yeem ua tau raws li qhov xav tau ntau dua.
Titanium extrusion txheej txheem txheej txheem
Titanium hlau nyem casting txheej txheem kuj muaj xws li ncaj qha extrusion, indirect extrusion thiab convex pwm pressurized solidification thiab lwm txoj kev. Hauv kev xyaum, raws li cov duab tshwj xeeb ntawm cov khoom, qhov loj me thiab kev ua haujlwm yuav tsum xaiv cov txheej txheem tsim nyog.
Titanium extrusion casting cov ntaub ntawv tshawb fawb
Titanium hlau nyob rau hauv lub nyem casting molding tshuab nyob rau hauv daim ntawv thov ntawm kev tshawb fawb tsis yog tsuas yog txhawj xeeb txog nws cov yooj yim lub cev thiab tshuaj zog, tab sis kuj muaj xws li cov khoom hloov kho, alloying thiab cov ntaub ntawv sib xyaw.
Titanium alloy: los ntawm kev ntxiv cov khoom tsim nyog ntawm alloying ntsiab (xws li txhuas, vanadium, molybdenum, thiab lwm yam), lub zog thiab corrosion kuj ntawm titanium hlau tuaj yeem txhim kho ntxiv kom tau raws li qhov xav tau ntawm ntau yam kev siv.
Titanium matrix composites: los ntawm compounding titanium hlau nrog ceramics, intermetallic tebchaw thiab lwm yam reinforcing theem, titanium matrix composites nrog zoo heev kev ua tau zoo yuav npaj tau. Cov khoom sib xyaw no muaj cov ntawv thov dav dav hauv aerospace, tiv thaiv thiab lwm yam haujlwm.
