Mullite xuab zeb hmoov rau casting

Mullite xuab zeb hmoov rau casting yog tsim los ntawm siab - zoo aluminosilicate raw cov ntaub ntawv, feem ntau muab los ntawm kaolin thiab hloov mus rau hauv mullite los ntawm siab -kub calcination. Cov khoom kawg muaj feem ntau ntawm mullite (3Al₂O₃·2SiO₂) thiab nthuav tawm cov tshuaj lom neeg ruaj khov zoo, ua rau nws zoo tagnrho rau cov ntawv thov precision casting.
Nyob rau hauv cov txheej txheem casting precision, cov khoom siv xuab zeb ncaj qha txiav txim siab qhov roughness ntawm qhov chaw thiab tsim qhov tseeb ntawm cov casting. Mullite hmoov, vim nws zoo heev - kub tsis kam thiab thermal stability, tau dhau los ua ib qho ntawm cov khoom siv dav siv ntau tshaj plaws hauv cov txheej txheem precision casting- ua tshuab.
Piv rau cov xuab zeb zoo tib yam silica xuab zeb, cov hmoov mullite tsis tshua muaj kev hloov pauv thiab hloov pauv ntawm qhov kub thiab txias, tiv thaiv lub plhaub tawg, delamination, thiab qhov chaw tsis xws luag hauv castings. Ib txhij, nws cov tshuaj zoo heev inertness txo qhov yaig ntawm lub plhaub pwm los ntawm cov hlau molten, txhim kho cov txiaj ntsig casting.

Cov khoom no tuaj yeem siv los ua cov xuab zeb saum npoo av, lossis ua cov txheej txheem hloov pauv lossis txheej txheej hmoov zoo raws li cov txheej txheem yuav tsum tau ua, hloov mus rau cov qauv sib txawv thiab cov txheej txheem hlau.
Mullite xuab zeb hmoov rau casting yog cov khoom siv deg refractory tshwj xeeb tsim los siv rau hauv cov txheej txheem casting precision. Nws yog tsim los ntawm siab -zoo hluavtaws los yog sintered mullite los ntawm crushing, grading, sieving, los yog ultrafine sib tsoo. Cov khoom no feem ntau yog siv los ua cov txheej txheem saum npoo los yog hloov pauv hauv lub plhaub - ua cov txheej txheem, ua lub luag haujlwm txiav txim siab hauv qhov zoo ntawm cov castings.
