Yakakwira alumina zvidhinha inogadzirwa nekusarudza bauxite chamotte sechinhu chikuru mbishi, inopfurwa pa1450-1470 ° C nemaitiro epamberi ane hutongi hwemhando yepamusoro. Yakakwira Alumina Moto Zvidhinha inogadzirwa nealuminium kana zvimwe zvinhu zvakasvibirira zvine yakakwirira alumina zvemukati kuburikidza nekuumba uye kupfura. nekuda kweiyo isina kwayakarerekera refractory pfuma alumina refractory inogona kuramba acid slag erosion resistance.
High Alumina Brick Process
Pinda kuburikidza Sarudza uye sieve chamotte ye deironing isati yapwanya, iyo inogona kuvandudza yakakwirira alumina zvidhinha kunaka. Nekuti kune yakakwira chikamu chegrog mune zvinongedzo zvinogona kusvika 90 ~ 95%. Sarudza uye kuongorora deironing isati yapwanyika grog.
MaGrade matatu eHigh Alumina Brick
Zvinoenderana neakasiyana Al2O3 zvemukati, High alumina zvidhinha zvinogona kuiswa muMagiredhi Matatu muChina.
Giredhi I High Alumina Zvidhinha zvine zvinopfuura 75% Al2O3 zvemukati.
Grade II High Alumina Bricks ine 60~75% Al2O3 zvirimo.
Giredhi III High Alumina Zvidhinha zvine 48~60% Al2O3 zvirimo.
Zvimiro zveHigh Alumina Brick
Yakakwira alumina zvidhinha zvine maficha akaita senge tembiricha yakakwira kuita, ngura huru uye kusapfeka, kusimba kwehuzhinji, kuderera kwesimbi, nezvimwe.

High Alumina Brick Application
Yakakwira alumina zvidhinha inogona kushandiswa muchoto chinoputika, chitofu chinopisa, choto chemagetsi. zvakare yakakwirira alumina moto zvidhinha zvinoshandiswa muminda yesimbi nesimbi, nonferrous, girazi, simende, ceramics, petrochemical, muchina, boiler, chiedza indasitiri, simba, uye indasitiri yemauto nezvimwe.
