Ceramic Sand rau Poob Foam Casting

Lus piav qhia luv luv:

Ceramic xuab zeb rau foundry muaj kev ua tau zoo rov qab siv dua: cov kev xav tau qis rau cov khoom siv kho xuab zeb, kev siv hluav taws xob tsawg thiab tus nqi qis rau kev kho xuab zeb. Cov xuab zeb rov qab mus txog 98%, tsim cov khib nyiab tsawg dua. Vim tias tsis muaj binder, qhov poob ua npuas dej puv xuab zeb muaj qhov rov qab zoo dua thiab tus nqi qis dua, ncav cuag 1.0-1.5kg / tuj ntawm xuab zeb noj ntawm castings.

Product Detail

Khoom cim npe

Nyob rau hauv xyoo tas los no, poob ua npuas ncauj casting tuam txhab tau cuam tshuam los ntawm ntau yam, uas ua rau tsis tshua muaj peev xwm ntawm cov tiav castings. Ntawm lawv, cov nqi ntau lawm ntawm castings, siab tsis zoo tus nqi thiab tsis zoo tau dhau los ua peb qhov teeb meem nyob rau hauv lub poob ua npuas ncauj casting tuam txhab nyob rau hauv Suav teb. Yuav ua li cas los daws cov teeb meem no thiab txhim kho cov nqi kev ua tau zoo ntawm cov khoom siv casting thaum ntxov tau dhau los ua ib qho ntawm cov haujlwm saum toj kawg nkaus ntawm cov tuam txhab foundry. Raws li peb txhua tus paub, kev xaiv cov xuab zeb hauv cov txheej txheem casting yog ib feem tseem ceeb ntawm tag nrho cov txheej txheem. Thaum cov xuab zeb tsis raug xaiv kom raug, nws yuav cuam tshuam rau tag nrho cov xwm txheej. Yog li ntawd, qhov poob ua npuas ncauj casting tuam txhab yuav tsum tau siv zog ntau dua hauv kev xaiv cov xuab zeb.

Raws li cov ntaub ntawv tseem ceeb, feem ntau cov tuam txhab nrhiav tau txhim kho lawv cov kev xaiv ntawm cov xuab zeb, tsis lees txais cov tsoos quartz xuab zeb lossis forsterite xuab zeb, thiab siv hom tshiab ntawm cov xuab zeb ceramic los txhim kho qhov teeb meem casting. Cov xuab zeb tshiab no muaj qhov zoo ntawm cov refractoriness siab, zoo fluidity, siab gas permeability thiab tib bulk ntom nrog quartz xuab zeb. Nws daws qhov tsis xws luag hauv casting ntau lawm rau qee yam, thiab tau muaj kev txhawj xeeb thoob ntiaj teb kev lag luam foundry. Peb qhov teeb meem loj ntawm cov nqi casting, qhov tsis zoo thiab qhov ua tau zoo ntawm kev poob ua npuas ncauj casting tuam txhab tau raug kho kom zoo, thiab cov pob zeb zeb ceramic kuj tau hlub los ntawm ntau lub lag luam.

Qhov zoo

● High refractoriness (＞1800°C)，can be used for casting various materials. There is also no need to use different sand type according to material.

● High reclamation tus nqi. Cov xuab zeb rov qab mus txog 98%, tsim cov khib nyiab tsawg dua.

● Zoo heev fluidity thiab filling efficiency vim yog kheej kheej.

● Tsawg Thermal expansion thiab Thermal Conductivity. Casting qhov ntev yog qhov tseeb dua thiab qis conductivity muab pwm ua haujlwm zoo dua.

● Tsawg qhov ntom ntom. Raws li cov xuab zeb dag ceramic yog ib nrab ntawm lub teeb li fused ceramic xuab zeb (dub pob xuab zeb), zircon thiab chromite, nws tuaj yeem tig tawm li ob zaug ntawm cov pwm ntawm ib chav tsev qhov hnyav. Nws tseem tuaj yeem ua haujlwm yooj yim heev, txuag kev ua haujlwm thiab hloov cov nqi hluav taws xob.

● Kev muab khoom ruaj khov. Txhua xyoo muaj peev xwm 200,000 MT kom ceev thiab ruaj khov khoom.
