Zvidhinha zve alumina zvine arumina yakawanda zvinogadzirwa ne chamotte ye bauxite yakasarudzwa sezvinhu zvikuru, zvinopiswa pa 1450-1470°C nemaitiro epamusoro-soro nekudzora kwakasimba kwemhando. Zvidhinha zve alumina zvine arumina yakawanda kana zvimwe zvinhu zvine alumina yakawanda kuburikidza nekuumba nekupisa. Nekuda kwesimba rayo rekusagadzikana, alumina inogona kuramba kukanganiswa nekukanganiswa ne acid slag.
Maitiro Ekugadzira Zvidhinha zveAlumina Yakakwira
Pinda muSelect uye sefa chamotte kuti ibvise maayina usati wapwanya, izvo zvinogona kuwedzera kunaka kwezvidhinha zvealumina. Nekuti kune huwandu hwakawanda hwemaayina muzvinhu zvinogona kusvika 90-95%. Sarudza uye ongorora maayina asati apwanywa.
Magiredhi Matatu eHigh Alumina Brick
Zvichienderana nehuwandu hwakasiyana hweAl2O3, zvidhinha zvealumina zvakawanda zvinogona kupatsanurwa muzvikamu zvitatu muChina.
Zvidhinha zveAlumina High zveGiredhi I zvine huwandu hweAl2O3 hunopfuura 75%.
Zvidhinha zveAlumina High zveGiredhi II zvine huwandu hwe60~75% hweAl2O3.
Zvidhinha zveAlumina High zveGiredhi III zvine huwandu hwe48~60% hweAl2O3.
Zvimiro zveHigh Alumina Brick
Zvidhinha zve alumina zvine zvinhu zvakanaka zvakaita sekushanda zvakanaka pakupisa kwakanyanya, kuramba ngura uye kusakara zvakanaka, huwandu hwakawanda hwesimbi, simbi shoma, nezvimwewo.
