Hauv kev ua hlau casting, qhov zoo ntawm molding xuab zeb ncaj qha cuam tshuam rau qhov tseeb, zoo thiab kev tsim khoom ntawm castings. Raws li cov khoom siv refractory aluminosilicate ua tau zoo,mullite xuab zeb rau castingyog nyiam los ntawm kev lag luam casting siab kawg vim nws qhov kev tiv taus kub zoo heev, kev ruaj khov ntawm qhov ntev thiab kev tsis muaj tshuaj lom neeg. Tsab xov xwm no tsom mus rau kev qhia txog nws cov ntawv thov tseem ceeb thiab cov txiaj ntsig, pab koj nkag siab txog qhov tseem ceeb ntawm mullite xuab zeb rau kev casting hauv kev ua kom zoo dua cov txheej txheem thiab txo cov nqi.
Cov Ntawv Thov Tseem Ceeb
1. Kev Ua Peev Xwm Precision Casting:Nws yog cov khoom siv tseem ceeb rau kev ua plhaub hauv kev casting ploj-wax, siv rau hauv txheej thaub qab thiab txheej txhawb nqa. Sib xyaw nrog silica sol thiab mullite hmoov, nws tuaj yeem tsim lub plhaub ntom thiab muaj zog, uas tuaj yeem tiv taus kev hloov pauv thiab tawg thaum lub sijhawm ci thiab nchuav, ua kom ntseeg tau qhov tseeb ntawm cov khoom xws li aero-engine turbine blades thiab lub cav tsheb.
2. Kev Ua Haujlwm Hnyav:Nrog rau qhov refractoriness ntawm ≥1750 ℃, nws tuaj yeem tiv taus qhov kub siab tshaj 1600 ℃ thiab tiv taus qhov kev yaig ntawm cov hlau molten thiab slag. Raws li molding xuab zeb lossis core xuab zeb rau cov hlau loj castings thiab hlau castings, nws tuaj yeem tswj tau qhov kev ncaj ncees ntawm cov pwm, zam kev puas tsuaj xws li xuab zeb suav nrog, thiab txo cov nqi ua haujlwm ntawm kev ntxuav tom qab nchuav.
3. Kev Sib Tov Tshwj Xeeb:Nws cov hlau tsawg thiab titanium cov ntsiab lus thiab kev ruaj khov tshuaj zoo tuaj yeem tiv thaiv kev tsis haum tshuaj nrog cov hlau tshwj xeeb molten (xws li stainless hlau thiab cov hlau kub siab), zam kev ua qias tuaj thiab oxide suav nrog, thiab xyuas kom meej qhov huv thiab qhov tiav ntawm cov castings.
Cov txiaj ntsig tseem ceeb
Mullite xuab zeb rau kev casting daws cov teeb meem mob ntawm cov xuab zeb molding ib txwm muaj: kev tiv taus kub siab heev (≥1750 ℃) ua kom muaj kev ruaj khov ntawm pwm; cov coefficient nthuav dav thermal qis tswj qhov tseeb ntawm qhov ntev; kev tsis muaj tshuaj lom neeg tiv thaiv kev casting zoo; kev nkag tau zoo ntawm huab cua txo cov qhov tsis zoo xws li qhov cua. Nws tuaj yeem txhim kho tus nqi tsim nyog ntawm kev castings thiab txo cov nqi tom qab ua tiav, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov xwm txheej casting uas xav tau ntau.
Cov Lus Qhia Txog Mesh
Peb cov xuab zeb mullite rau kev casting muaj ntau yam kev qhia mesh, npog cov kev xav tau ntawm ntau yam xwm txheej casting. Cov qhov loj me me ib txwm muaj xws li 8-16 mesh, 16-30 mesh, 30-60 mesh, 60-80 mesh thiab 80-120 mesh. Peb kuj muab cov lus qhia hmoov mullite xws li 200 mesh thiab 300 mesh, uas tuaj yeem phim ncaj qha nrog cov txheej txheem sib txawv ntawm kev nqis peev precision casting, hnyav-duty casting, tshwj xeeb alloy casting, thiab lwm yam. Ntawm lawv, 30-60 mesh feem ntau yog siv rau kev tsim cov slurry thaub qab, thiab 16-30 mesh yog qhov tsim nyog rau kev siv txheej txhawb nqa, ua tau raws li cov kev xav tau tshwj xeeb ntawm ntau yam txheej txheem.
Kev Pabcuam Kev Kho Kom Haum
Peb siv cov kab tsim khoom ntse niaj hnub thiab pab pawg R&D tshaj lij, peb muaj peev xwm hloov kho tau zoo. Peb tuaj yeem tsim cov khoom xuab zeb mullite nrog cov qhov loj me tshwj xeeb (tuaj yeem hloov kho los ntawm 10 mesh txog 325 mesh), kev huv thiab kev hloov pauv me me raws li cov neeg siv khoom cov txheej txheem casting tshwj xeeb, cov ntaub ntawv casting thiab cov kev xav tau kev ua tau zoo. Txij li kev xaiv cov khoom siv raw, kev hloov kho qhov loj me me mus rau kev tshuaj xyuas zoo, peb muab kev pabcuam ib-rau-ib tag nrho, hloov kho tau yooj yim rau cov kev xav tau ntawm ntau yam lag luam xws li kev tsav dav hlau, tsheb thiab metallurgy. Tib lub sijhawm, peb xyuas kom meej tias muaj kev ruaj khov ntawm kev muab khoom thiab kev sib xws ntawm qhov zoo, pab cov neeg siv khoom txhim kho cov txheej txheem tsim khoom thiab txhim kho kev sib tw khoom.
