Aggregates ndiwo musana wekuumbwa kwerefractory uye inopa kugadzikana kwedimensional kune zvigadzirwa zvinoramba. Iwo akaomesesa mafractions anowedzera kupisa kutyisa uye corrosion kuramba uye mafiindi akaunganidzwa anogonesa kugovera saizi yechikamu uye anowedzera kuramba kwechigadzirwa.
Unhu hunopindirana hweTabular alumina ndiyo mhedzisiro yeinodzorwa zvakanaka sinter process ine kupisa kwekushisa kunopfuura 1800 ° C. Kushandiswa kwekushisa kwekushisa kwepamusoro nehunyanzvi hwemazuva ano kunobvumira densification yezvinhu zvakasarudzwa zvakasvibirira pasina sintering aids iyo inogona. zvinokanganisa zvakanyanya kupisa kwekushisa kweiyo refractories.
Nekuda kweiyo sinter process, iwo akaunganidzwa anoratidza yakafanana mineralogical uye makemikari kuumbwa kwezvikamu zvese. Kupesana nezvigadzirwa zvakasanganiswa apo tsvina inoungana mufaindi, kushandiswa kwe sintered aggregates mukugadzira refractory kunovimbisa kugadzikana uye kuvimbika maitiro.
Junsheng inopa masaizi akasiyana-siyana ezvikamu kubva kune zvakakasharara kusvika kune akatsetseka-pasi saizi ye <45 μm uye <20 μm. Kupwanya uye kugaya kunoteverwa neyakaomesesa de-ironing matanho anokonzeresa yakaderera yemahara iron mukati mezvikamu zvakasiyana.
Tabular Alumina ndicho chinhu chesarudzo mune isina kuumbwa yakakwira performance refractories inoshandiswa mumaindasitiri akasiyana siyana anosanganisira simbi , foundry , simende , girazi , prtrochemical , ceramic , uye tsvina incineration . Zvimwe zvakajairika zvisiri-refractory application zvinosanganisira kushandiswa kwayo muchoto fenicha uye nekusefa kwesimbi.
