Alumina castable refractory muaj cov hmoov av, xuab zeb zoo li thiab yog cov khoom siv amorphous refractory. Nws yog tsim los ntawm raw alumina li aggregate, hmoov thiab binder rau hauv ib homogeneous sib tov uas tuaj yeem yooj yim molded thiab ntsia tau rau hauv ntau hom kev siv kub. Alumina refractory castables muaj cov cua kub zoo heev, thermal shock tsis kam thiab siab zog. Nws yog feem ntau siv nyob rau hauv ntau yam kub kub hnyav ib puag ncig, xws li hauv ob sab phlu ntawm high-temperature kilns, moj tej tawg rauv, incinerators thiab lwm yam khoom siv.

Qhov zoo ntawm Alumina Castable Refractory
Kub-kub Resistance
Alumina castables refractory muaj ib tug loj npaum li cas ntawm alumina thiab muaj ib tug siab melting point, feem ntau ntawm 1000 degree thiab 1700 degree. Nws tuaj yeem tswj hwm kev ruaj ntseg hauv qhov chaw siab heev thiab tsim nyog rau kev lag luam kub kub xws li steelmaking thiab cement.
Impact Resistance
Binders rau alumina castables refractory muab lub zog thiab cohesion rau cov castable. Kev cuam tshuam tsis zoo txhais tau tias nws tuaj yeem tiv taus kev poob siab thiab kev ntxhov siab siab yam tsis muaj kev tawg.
Tsawg Bulk Density thiab Porosity
Kev siv dej ntawm alumina castables refractory yog ib nrab ntawm cov castables zoo tib yam, uas txhim kho cov compactness ntawm castables thiab txo cov porosity. Tsawg porosity txhim kho kev siv hluav taws xob los ntawm kev txo qis kev nkag mus ntawm slag thiab corrosive gases thiab txo cov cua sov los ntawm cov khoom siv.
Zoo hnav tsis kam
Kev hnav tsis kam ntawm cov castable tuaj yeem tiv taus qhov hnav ntawm cov khoom siv los yog kua, uas tuaj yeem ua rau lub neej ntawm lub cub tawg thiab txo cov nqi kho.
Cov tshuaj tiv thaiv zoo heev
Alumina castables refractory yog heev resistant rau acids, alkalis, thiab lwm yam corrosive tshuaj. Lawv tiv taus cov tshuaj tiv thaiv kab mob uas yuav ua rau cov kab mob refractory yaig, degradation, lossis kev puas tsuaj ntawm cov qauv. Alumina castable refractory tuaj yeem tiv taus cov cheeb tsam corrosive.
