Ndeupi mutsauko pakati yakakwirira alumina zvidhinha nezvidhina zvevhu

Zvidhinha zvisingaremi zvakakwirira-alumina zvinowanzoshandisa high-alumina bauxite clinker pamwe nehuwandu hushoma hwevhu. Mushure mekugadzirwa pasi, dzinodirwa uye dzakaumbwa muchimiro chedhaka nenzira yekugadzira gasi kana nzira yefuro, 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 nezvikamu zvisina kusvibiswa uye zvakasvibiswa nezvinhu zvakasimba zvekupisa zvakanyungudutswa. Kana yakanangana nemurazvo, tembiricha yekubata kumeso haifanire kunge yakakwira kupfuura 1350 ℃.

Zvidhinha zvevhu zvakareruka, zvinopisa zvekupisa zvinodzivirira zvinoreva refractories ine yakakwira porosity, yakaderera yakawanda density uye yakaderera thermal conductivity. Thermal insulation refractories inonzi zvakare lightweight refractories, iyo inosanganisira thermal insulation refractory zvigadzirwa, refractory fibers uye refractories Fiber zvigadzirwa. Thermal insulation refractories inoratidzirwa nepamusoro porosity, kazhinji 40% -85%; yakaderera yakawanda density isingasviki 1.5g/cm3; low thermal conductivity, kazhinji isingasviki 1.0W (mK). Inoita sechinhu chinopisa chekudzivirira chemidziyo yemaindasitiri, inogona kuderedza kurasikirwa kwekupisa kwechoto, kuchengetedza simba, uye kuderedza kunaka kwemidziyo yekupisa. Thermal insulation refractories ine simba rakashata remagetsi, abrasion resistance uye slag corrosion resistance, uye haina kukodzera kutakura-kutakura chimiro chemoto uye kutarisana zvakananga ne slag, charge, simbi yakanyungudutswa nezvimwe zvikamu.

Pane misiyano mune zvealuminium zvemukati, huremu hweyuniti, tembiricha yekushandisa, uye ruvara. Semuenzaniso: zvidhinha makumi manomwe neshanu zvealumina uye zvidhinha makumi mana nezvitatu zvevhu, zvikamu makumi manomwe neshanu zvinorema kupfuura 75kg. 43 yeanenge 75kg, tembiricha yekushandisa ye4.5 yakakwira alumina inenge 43, 3.65 yezvidhinha inenge 75, ruvara rwune makumi manomwe neshanu muchena, uye 1520 inorasika. Muchidimbu, musiyano mukuru.
