Dab tsi yog Ceramic Foam Lim siv rau? daws teeb meem Casting thoob plaws kev lag luam

Yog tias koj nyob rau hauv cov hlau casting, koj paub tias yuav raug nqi npaum li cas xws li porosity, inclusions, los yog tawg tuaj yeem ua tau.Ceramic Foam Lim (CFF) tsis yog "filters" xwb - lawv yog cov cuab yeej tseem ceeb los ntxuav cov hlau molten, txhim kho kev ncaj ncees, thiab txiav cov khoom pov tseg. Tab sis dab tsi yog lawv siv rau? Cia peb rhuav tshem lawv cov ntawv thov tseem ceeb los ntawm kev lag luam thiab hom hlau, yog li koj tuaj yeem pom tias lawv haum koj li cas

1. Non-Ferrous Hlau Casting: Ua Aluminium, Tooj, Zinc Castings Flawless

Cov hlau tsis-ferrous (aluminium, tooj liab, zinc, magnesium) tau siv dav hauv kev pib, hluav taws xob, thiab kav dej - tab sis lawv cov melts yog nquag oxide inclusions thiab gas npuas. Ceramic Foam Filters kho qhov no los ntawm kev ntxiab impurities ua ntej lawv ncav cuag cov pwm

Kev siv tseem ceeb ntawm no:

Aluminium Casting (qhov loj tshaj plaws uas tsis yog-ferrous siv rooj plaub):

Cov lim dej tshem tawm Al₂O₃ oxides thiab cov khib nyiab me me los ntawm molten aluminium, kom ntseeg tau tias du, muaj zog castings. Zoo meej rau:

Auto qhov chaw:Log, cav thaiv, kis tau tus mob vaj tse (tsawg dua tsis xws luag txhais tau tias lub neej ntev).

Aerospace Cheebtsam:Lub teeb yuag aluminium alloys rau aircraft thav duab (xav tau ultra-ntshiab hlau).

Cov khoom siv:Aluminium cookware, laptop casings (tsis muaj qhov chaw blemishes).

Copper & Brass Casting:

Traps sulfide inclusions thiab refractory fragments, tiv thaiv leaks hauv:

Cov kav dej kav dej:Valves, fittings, kav dej (tseem ceeb rau kev ua haujlwm ntawm cov dej nruj).

Cov khoom siv hluav taws xob:Brass connectors, terminals (ntshiab tooj liab kom zoo conductivity).

Zinc & Magnesium Casting:

Lim tswj oxide buildup nyob rau hauv high-pressure tuag casting (HPDC) rau:

Electronics:Zinc alloy xov tooj rooj plaub, magnesium laptop thav ntawv (cov phab ntsa nyias xav tau tsis muaj qhov tsis xws luag).

Kho vajtse:Zinc door handles, magnesium fais fab cuab tam qhov chaw (zoo ib yam).

2. Ferrous Hlau Casting: Kho Hlau, Hlau Castings rau Kev Siv Hnyav

Ferrous hlau (steel, cam khwb cia hlau) kov cov kev ntxhov siab - tab sis lawv cov kub kub melts (1500 ° C +) xav tau cov lim tawv tawv. Ceramic Foam Filters ntawm no thaiv cov slag, graphite fragments, thiab oxides uas rhuav tshem lub zog.

Kev siv tseem ceeb ntawm no:

Hlau & Stainless Hlau Casting:

Withstands kub steel melts los tsim txhim khu kev qha qhov chaw rau:

Industrial machinery:Hlau li qub, twj tso kua mis lub cev, gearboxes (tsis muaj kev tawg sab hauv = tsawg downtime).

Kev tsim kho:Stainless hlau structural brackets, rebar connectors (resists corrosion).

Cov cuab yeej kho mob:Stainless hlau phais cov cuab yeej, tsev kho mob dab dej (ntshiab hlau = siv nyab xeeb).

Hlau Casting:

Txhim kho microstructure rau:

Automotive:Grey hlau nres discs, ductile hlau crankshafts (kuav kev sib txhuam thiab torque).

Khoom siv hnyav:Cam khwb cia hlau tsheb laij teb qhov chaw, crusher puab tsaig (xav tau hnav tsis kam).

Cov kav dej:Grey hlau cov kav dej (tsis muaj qhov xau los ntawm kev suav nrog).

3. Tshwj xeeb High-Temp Casting: Tackle Titanium, Refractory Alloys

Rau kev siv huab cua (aerospace, nuclear), qhov twg hlau yog super-kub (1800 ° C +) lossis reactive (titanium), cov qauv lim tsis ua haujlwm. Ceramic Foam Lim (tshwj xeeb yog ZrO₂-raws li) yog tib txoj kev daws teeb meem.

Kev siv tseem ceeb ntawm no:

Titanium Alloy Casting:

Titanium melts react nrog rau feem ntau cov ntaub ntawv-tab sis ZrO₂ lim nyob twj ywm inert, ua:

Aerospace qhov chaw:Titanium cav hniav, aircraft tsaws iav (xav tau ultra-ntshiab hlau rau qhov siab).

Kev kho mob implants:Titanium hip hloov, kho hniav abutments (tsis muaj paug = biocompatible).

Refractory Alloy Casting:

Filter non-ferrous superalloys (nickel-based, cobalt-based) rau:

Kev tsim hluav taws xob:Nickel-alloy gas turbine qhov chaw ( tuav 1000 ° C + tso pa).

Nuclear kev lag luam:Zirconium alloy roj cladding (tiv thaiv hluav taws xob thiab kub kub).

Vim li cas Ceramic Ua Npuas Ncauj Lim Ntaus Lwm Cov Kev Xaiv?

Tsis zoo li hlau mesh lossis xuab zeb lim, CFFs:

Muaj cov qauv 3D ntxeem tau (cuav ntau impurities, txawm tias me me).

Tiv thaiv huab cua kub (1200-2200 ° C, nyob ntawm cov khoom siv).

Ua haujlwm nrog txhua yam hlau loj (txhuas rau titanium).

Txiav cov nqi seem los ntawm 30-50% (txuag sijhawm thiab nyiaj txiag).

Tau txais CFF Txoj Cai rau Koj Cov Cai Siv

Txawm hais tias koj tab tom casting txhuas qhov chaw pib, stainless hlau li qub, lossis titanium implants, peb muaj Ceramic Foam Lim raws li koj xav tau. Peb cov ntxaij lim dej ua tau raws li ISO / ASTM cov qauv, thiab peb pab neeg pab koj xaiv cov khoom tsim nyog (Al₂O₃ rau txhuas, SiC rau hlau, ZrO₂ rau titanium).
