Andalusite Mullite Cib rau Kub Blast Qhov cub

Andalusite Mullite Cib muaj kev ua tau zoo dua li cov cib andalusite zoo tib yam los yog mullite cib, Nws muaj qhov zoo dua spalling tsis kam, thermal shock kuj thiab cua yaig kuj. Nws yog feem ntau siv nyob rau hauv regenerator ntawm kub moj tej tawg qhov cub, loj phab ntsa txoj hauj lwm, steel-ua rauv thiab high-temperature industrial furnace nrog cov nyhuv zoo.

1, Kev piav qhia ntawm Andalusite Mullite Cib rau Kub Blast Qhov cub:: cua sov andalusite mus rau 1300 degree yuav hloov mullite theem, txhim khu cov khoom tiv thaiv kom txias txias thiab cua sov, txhim kho cov khoom cuam tshuam thiab load softening kub. Hongzhu pob zeb tuaj yeem ncaj qha ntxiv yam tsis muaj calcination los txhim kho cov creep kuj ntawm mullite cib. Qhov zoo ntawm cov cib sib xyaw no muaj kev ua haujlwm zoo oxidation, kub tsis kam, tsis kam tiv taus, kub compressive zog thiab flexural zog. Yog li ntawd, cov khoom siv dav siv hauv cov chaw tseem ceeb ntawm kilns.Qhov ntim nthuav dav ntawm mullite hauv cov txheej txheem ntawm mullite tsim ntawm qhov kub thiab txias tuaj yeem cuam tshuam cov sintering shrinkage ntawm qhov kub thiab txias, yog li ua rau lub ntim ntawm cov khoom ruaj khov. Qhov sib ntxiv ntawm andalusite ntawm qhov kub thiab txias yog hloov mus rau hauv mullite, uas txhim kho cov ntsiab lus ntawm mullite. Nyob rau tib lub sijhawm, cov qauv interweaved tsim los ntawm koob kab mullite txhim kho cov thermal shock stability ntawm cov khoom.Andalusite tsis tag mullitized, tsim ib tug xov tooj ntawm composite lug, thiab thermal shock stability ntawm cov khoom yog zoo dua vim lub mismatch ntawm expansion coefficients ntawm ntau yam minerals. Thaum andalusite ntxiv rau hauv lub matrix, lub microstructure ntawm knitted mullite interwoven nrog ib leeg yog tsim nyob rau hauv matrix tom qab Mullitization ntawm andalusite ntawm qhov kub thiab txias, uas muaj peev xwm zoo txhim kho lub load softening kub thiab creep kuj ntawm cov khoom.
