Zvinoumba zvidhinha zvisingaremi zvakakwirira zvealuminium

Zvidhinha zvisingaremi zvakakwirira-alumina zvinowanzodaidzwa kuti thermal insulation refractory bricks, inonziwo thermal insulation refractory bricks. Chinangwa chayo chakakosha ndechekudzivirira kupisa uye basa rekuchengetedza kupisa. Mukushandiswa kwakajairwa, haina kutarisana zvakananga nekupisa kwechoto, uye imhando yechigadzirwa chezvidhinha chinoramba chiri padyo nemadziro echoto uye chine kupisa kwekudzivirira uye kuchengetedza kupisa.

Chidhinha chakareruka chakakwira-alumina ndechimwe chezvakanakira kupisa kupisa refractory zvinhu parizvino. Iyo ine hunhu hwesimba rekumanikidza, yakaderera thermal conductivity, yakanaka insulation performance, uye mutengo wakaderera. Yakave ichishandiswa zvakanyanya mu ceramic tunnel kilns, roller kilns, uye shuttle kilns. Type kilns, kilns yemadziro, anoshandiswawo mumoto wakasiyana siyana wekupisa, coking furnaces uye zvimwe zvinopisa midziyo, kupisa kwekupisa kwekuisa zvinhu muindasitiri yesimbi nesimbi.

Zvidhinha zvisingaremi zvakakwirira-aluminium zvinodaidzwawo kuti high-alumina insulation zvidhinha. Yakareruka refractory zvinhu zvine alumina zvemukati pamusoro pe48%, kunyanya inoumbwa mullite uye girazi chikamu kana corundum. Hulk density i 0.4 ~ 1.35g/cm3. Iyo porosity i66% ~ 73%, uye iyo yekumanikidza simba i1～8MPa. Thermal shock resistance iri nani. Kazhinji, high alumina bauxite clinker inowedzerwa nehushoma hwevhu, mushure mekugadzirwa zvakanaka, inodururwa uye yakaumbwa mumhando yedhaka nenzira yekugadzira gasi kana nzira yefoam, uye inopisa pa 1300-1500 ° C. Dzimwe nguva maindasitiri alumina anogona kushandiswa kutsiva chikamu chebauxite clinker. Inoshandiswa kune lining uye kupisa kwekudzivirira kwemukati kwemasonry kilns, pamwe chete nezvikamu zvisina kusvibiswa uye zvakasvibiswa nezvinhu zvakasimba zvekupisa zvakanyungudutswa. Kana yakanangana nemurazvo, tembiricha yekubata pamusoro haifanire kunge yakakwira kupfuura 1350°C.
