Alumina ceramic raj yog ib yam khoom siv ceramic nrog alumina (Al2O3) raws li lub cev tseem ceeb, uas tuaj yeem siv rau hauv aerospace, cov cuab yeej siv tub rog yog ib hom kev siv dav siv ceramics, yog li cov teeb meem dab tsi yuav tsum tau them rau hauv kev teeb tsa ntawm alumina ceramic raj?

1. Thaum txhim kho cov kav dej alumina ceramic, yog siv cov kav dej hloov tau yooj yim, ob qhov kawg ntawm cov kav dej hloov tau yooj yim hauv lub tes tsho nkag yuav tsum tau kho symmetrically.
Vim tias qhov nthuav dav coefficient ntawm cov kav dej tsuas yog kwv yees li ib feem peb ntawm cov hlau, uas yog hais, qhov sib txawv ntawm qhov nthuav dav yuav raug txo los ntawm 3-5MM. Tsis tas li ntawd, lub ntsej muag kawg ntawm cov yeeb nkab sib xyaw thiab lub ntsej muag kawg ntawm flange yuav tsum tau yaug nrog ib leeg thaum txuas cov flanges.
2. Lub alumina-lined ceramic raj muaj lub sijhawm siv ntev heev thiab muaj zog hardness thiab toughness. Txawm li cas los xij, nws yuav tsum tau ua tib zoo saib xyuas thaum lub sijhawm thauj mus los thiab kev teeb tsa, thiab kev sib tsoo yog nruj me ntsis txwv tsis pub, thiab kev saib xyuas tshwj xeeb yuav tsum tsis txhob kov cov cuab yeej hlau.
Vim muaj kev ua haujlwm siab, cov raj xa dej tuaj yeem txuas nrog vuam. Thaum welding cov khoom siv nozzle, 45 degree -60 degree "V" hom nqes hav P yuav tsum yog 2-4mm, thiab tom qab ntawd txuas nrog lub me me tam sim no, tsis muaj qhov sib txawv thaum lub sij hawm tsim kho.
3. Thaum txhim kho alumina ceramic yeeb nkab, xyuas kom meej tias cov kab nruab nrab ntawm cov yeeb nkab alumina ceramic yog ua raws li qhov nruab nrab ntawm cov yeeb nkab, thiab theem qhov siab kom ntseeg tau tias ob lub ntsej muag kawg yog txuas nrog.
Lub misalignment ntawm ob qhov kawg yuav tsum tau tswj nyob rau hauv 1.0mm, thiab cov kev taw qhia ntawm cov ntws ntawm lub conveying nruab nrab yuav tsum tau raws li cov kev taw qhia qhia los ntawm lub xub thaum lub sij hawm installation, thiab ntev kawg yog cov kev taw qhia ntawm lub qhov hluav taws xob.
