Sintered Corundum Brick se yon pwodwi REFRACTORY te fè nan sinterize dans alumina kwiyèr. Sintered Corundum brik gen yon pwen k ap fonn segondè, pèfòmans ki estab nan tanperati ki wo, bon fòs mekanik ak rezistans mete nan tanperati chanm ak tanperati ki wo. Li gen ekselan rezistans nan korozyon metal, oksidasyon ak rediksyon.
Materyèl yo anvan tout koreksyon yo itilize yo pwodwi brik corundum sinter yo se wo-pite alumina endistriyèl, ki se kalsine ak tè tise byen (pafwa yon ti kantite lajan nan MgO aditif yo te ajoute nan amelyore estrikti kristal li yo), bourade nan yon kò vèt, ak kalsine nan pi wo a 1850 degre. High-tanperati kalsinasyon diminye porositë yo nan estrikti nan kò vèt ak ogmante gwosè a grenn jaden pa sou 25 a 40 fwa. Bon kristal corundum sinterize gen yon estrikti plak dans-tankou.
Se korunm nan sinterize ak porositë mwens pase 3% ak dansite esansyèl pi gran pase 3.6 0 g/cm3 se kraze nan gwosè a patikil yo mande pou fè brik. Pwopriyete fizik ak chimik nan matyè premyè yo se jan sa a: Al2o 3 99. 17%~ 99.31%, sio 2 0. 19%~ 0. 0. 0 5%~ 0. 0.6%~ 1.0%, aparan porositë 2.3%~ 3.7%, esansyèl dansite 3.60 ~ 3.66g/cm ', vre dansite 3.69 ~ 3.80g/cm3.

Pwodwi Deskripsyon
The production process of sintered zirconium corundum bricks is to crush the sintered corundum into 3mm coarse particles and some fine powders less than 0.074mm, and some are mixed with a small amount of clay and other binders, and then formed with a high-pressure friction brick press or an oil press. After drying, the bricks are loaded into a high-temperature kiln for firing. Generally, the sintered zirconium corundum bricks with higher purity have a firing temperature of 1750~1800℃. If a small amount of clay or additives are added, the firing temperature can be 1600~1700℃. The physical and chemical properties of sintered corundum bricks are as follows: Al2O3>95%, refractoriness greater than 1790℃, apparent porosity less than 14%, bulk density 3.22g/cm3, compressive strength>1 0 0 MPa, ranpe pousantaj (1550 degre, 50h) 0.5%, ak chaj tanperati adousi (t0.6) pi gran pase 1700 degre. Sintered Corundum brik te fè nan sterded corundum gen segondè pite ak ekselan pwopriyete fizik. Sintered zirkonyòm corundum brik yo sitou itilize nan founo eksplozyon ak raffinage founo deyò gwo founo dife a nan four an vè ak endistri métallurgique. Yo menm tou yo itilize lajman nan four endistriyèl tankou endistri chimik ak elektwonik.
