Kev pabcuam av nplaum refractory cib tsim, Ntau Lawm, Kev Tsim Kho

Cov av nplaum ntawm ntau tshaj SK30 muaj ntau dua 30% Alumina thiab yog tsim los ntawm cov khoom siv ntawm cov qib siab tsis xws luag ntawm kev coj dawb huv ntawm Bauxite thiab av nplaum tsis kam. Rau kev pabcuam hauv cov xwm txheej hnyav, Rewell av nplaum Alumina cib muaj cov cuab yeej ua tau zoo, muaj peev xwm tiv taus thermal spalling, thiab muaj peev xwm tiv cov tshuaj lom neeg los ntawm vilable alkaies thiab qee qhov slag. Peb tsim thiab tsim alumina cib kom tau raws li qhov yuav tsum tau ua ntau yam ntawm cov kev pabcuam zoo meej tswj kev ua haujlwm.

Av nplaum hluav taws cib yog ib qho ntawm cov cib hluav taws. Nws Al2O3 cov ntsiab lus yog nruab nrab 30% thiab 48%. Cov av nplaum hluav taws ua kom zoo yog ua los ntawm cov av ua kom zoo dua qub lossis cov kaolin thiab cov av nplaum clinker ua ke nrog cov av nplaum, uas yog tsim los ntawm cov semi-qhuav lossis cov qauv yas thiab ci hauv qhov kub ntawm 1250-1420.
Cov yam ntxwv ntawm av nplaum refractory cib:
1. Tsawg qis porosity thiab muaj zog ntom ntom.
2. Zoo tsis kam mus rau permeability thiab zoo corrosion kuj.
3. Kev ntsuas kub muaj zog, kev pab lub neej ntev.
