Cov ntsiab lus Al2O3 siab Cenospheres rau cov tes tsho riser insulating tes tsho,
Cov ntsiab lus Al2O3 siab Cenospheres,
Cov ntawv thov ntawm cenospheres hauv Foundries yog dab tsi?

1. Cov Khoom Siv Refractory Sib DuaCenospheres yog cov khoom me me, tsis hnyav thiab khoob. zoo heev rwb thaiv tsev cov khoom. Lawv tuaj yeem ntxiv rau cov khoom siv refractory siv hauv cov chaw tsim khoom kom txo qhov ceev ntawm cov khoom siv yam tsis muaj kev cuam tshuam nws lub zog. Qhov no pab ua tiav kev txuag hluav taws xob thiab txhim kho cov txheej txheem foundry qhov kev ua haujlwm tag nrho.

2. Kev Sau Cov Core: Cenospheres siv tau ua cov khoom siv rau cov hlau ua los ntawm cov hlau. Cov hlau ua los ntawm cov hlau yog siv los tsim cov qhov thiab cov duab nyuaj hauv cov castings. Los ntawm kev ntxiv cenospheres rau cov hlau, qhov hnyav ntawm cov hlau raug txo, ua rau nws yooj yim dua rau kev tuav thiab ua rau kev siv cov hlau kim dua tsawg dua.

3. Cov Khoom Siv Xuab Zeb: Cov cenospheres tuaj yeem sib xyaw nrog cov xuab zeb foundry kom txhim kho lawv cov yam ntxwv. Kev ntxiv cov cenospheres tuaj yeem txhim kho qhov ntws ntawm cov xuab zeb, txo nws qhov ceev, thiab txhim kho qhov zoo ntawm kev casting. Cenospheres kuj muab cov cua sov rwb thaiv tsev rau pwm, ua rau lub sijhawm solidification txo qis thiab txhim kho qhov tiav casting.

4. Cov Txheej Txheem Tiv Thaiv KubCov Cenospheres siv tau rau hauv cov txheej txheej thermal barrier (TBCs) siv rau cov pwm thiab cov cores hauv cov pwm. TBCs siv los tiv thaiv cov pwm thiab cov cores los ntawm kev kub siab, tiv thaiv kev tawg thiab txhim kho lawv lub neej tag nrho. Cov Cenospheres siv tau rau hauv cov qauv TBC los txhim kho lawv cov khoom rwb thaiv tsev thiab txo qhov hloov pauv cua sov.

5. Kev lim dejCov Cenospheres siv tau ua cov khoom siv lim dej hauv cov chaw tsim khoom. Lawv tuaj yeem ntxiv rau cov lim dej siv hauv cov tshuab lim hlau molten kom ntes cov khoom tsis huv thiab cov khoom khov, ua rau cov hlau huv dua thiab zoo dua qub.

6. Cov Khoom Siv Sib Nqus: Cenospheres tuaj yeem siv ua cov khoom siv sib nqus hauv cov khoom siv hlau, xws li cov tshuaj pleev xim thiab cov khoom sib xyaw. Lawv txhim kho qhov sib piv ntawm lub zog thiab qhov hnyav ntawm cov khoom kawg, txo qhov ceev, thiab txhim kho cov khoom rwb thaiv tsev.

Zuag qhia tag nrho, cenospheres pom ntau yam kev siv hauv cov chaw tsim khoom, xws li cov khoom siv refractory sib dua mus rau qhov chaw sau cov hauv paus, cov khoom ntxiv xuab zeb, cov txheej txheem tiv thaiv thermal, kev lim dej, thiab cov khoom ntim sib dua. Lawv cov yam ntxwv tshwj xeeb ua rau lawv yog cov khoom ntxiv muaj txiaj ntsig rau kev ua kom zoo dua cov txheej txheem tsim khoom thiab txhim kho qhov zoo thiab kev ua haujlwm ntawm kev ua haujlwm casting.

Cov cenospheres yog cov khoom me me uas tsis hnyav, hollow microspheres uas feem ntau siv los ua cov khoom siv rau hauv ntau yam kev siv, suav nrog cov txheej txheem foundry xws li casting. Riser sleeves, tseem hu ua feeders, yog siv rau hauv casting los muab cov khoom siv hlau molten kom ruaj khov los them rau kev shrinkage thaum cov hlau txias thiab khov. Ntxiv cenospheres rau riser sleeves tuaj yeem muab qee qhov zoo, tab sis lawv siv yuav tsum tau xav txog zoo.

Nov yog li cas cenospheres siv tau rau hauv riser tes tsho thiab cov txiaj ntsig zoo:

Txo Qhov Hnyav: Cenospheres tsis hnyav, uas tuaj yeem pab txo qhov hnyav tag nrho ntawm lub riser sleeve. Qhov no tuaj yeem pab tau rau cov ntawv thov uas qhov hnyav ntawm lub riser xav tau kom tsawg.

Kev rwb thaiv tsev: Cov cenospheres muaj cov khoom rwb thaiv tsev zoo. Ntxiv lawv rau hauv lub tes tsho riser tuaj yeem pab txo qhov poob cua sov ntawm cov hlau molten, ua rau nws nyob twj ywm molten ntev dua thiab ua kom muaj kev pub mov zoo dua ntawm cov casting thaum nws khov.

Kev Tswj Txias: Cov khoom rwb thaiv tsev ntawm cenospheres tuaj yeem ua rau kev tswj thiab maj mam txias ntawm cov hlau molten hauv lub tes tsho riser. Qhov kev tswj txias no tuaj yeem txo qhov kev tsim cov qhov tsis zoo xws li kua muag kub thiab tawg hauv qhov casting.

Kev Them Nyiaj Rau Qhov Ntsws: Cov Cenospheres tuaj yeem pab them rau qhov kev ntsws ntawm cov khoom khov los ntawm kev muab cov hlau uas yaj thaum lub casting txias. Qhov no tuaj yeem txhim kho qhov zoo ntawm qhov casting los ntawm kev txo qhov yuav tshwm sim ntawm qhov tsis zoo uas cuam tshuam nrog kev ntsws.
