Yintoni umahluko phakathi kwe-bauxite ekrwada kunye ne-bauxite ephekiweyo?

Ilizwe lam ngumvelisi omkhulu kunye nomthengisi wezinto ezichasayo, kunye nemveliso ye-refractory ebalwa kwi-65% yetotali yehlabathi. I-Bauxite yenye yezinto eziphambili zokuvelisa izinto eziphikisayo. I-Bauxite kwi-industry refractory ngokuqhelekileyo ibhekisela kwi-bauxite ore kunye ne-calcined Al2O3 umxholo we-≥48% kunye nomxholo ophantsi we-Fe2O3. Njengemathiriyeli ekrwada ebalulekileyo yemathiriyeli ephikisayo, i-bauxite ikwindawo engenakubuyiselwa.

Umahluko omkhulu phakathi kwe-bauxite ekrwada kunye ne-bauxite ephekiweyo ziindidi zamaminerali ahlukeneyo: izinto eziluhlaza yi-kaolinite kunye ne-diaspore, kunye ne-clinker yi-mullite. I-Bauxite clinker, ebizwa ngokuba yimathiriyeli ephezulu ye-alumina, izitena ezahlukeneyo ze-alumina eziphakamileyo ezenziwe kwi-clinker yayo zizinto eziphikisayo okanye ezichasayo ezisetyenziswa kakhulu kwishishini lesinyithi kunye namanye amashishini, ngakumbi asetyenziswa phezulu kwiziko lombane, izitena eziqhumayo kunye neziqhumiso ezitshisayo. . Isiphumo esichasayo sibaluleke kakhulu, kwaye ukusebenza kwayo kungcono kunezitena eziqhelekileyo zodongwe. I-Bauxite: i-aluminium oxide ore ene-chemical formula Al2O3.H2O, Al2O3.3H2O kunye nenani elincinci le-FE2O3.SiO2. Idla ngokuba tyheli ukuya kobomvu kuba iqulethe i-iron oxide, ngoko ikwabizwa ngokuba yi "iron vanadium earth". Yeyona imathiriyeli ekrwada yokunyibilikisa ialuminiyam. I-Bauxite yahlulwe kwibakala le-metallurgical, ibakala lekhemikhali, ibakala le-refractory, ibakala lokusila, ibakala lesamente, njl njl ngokusetyenziswa kwayo.

Isetyenziselwa ukwenza izinto eziphikisayo, olu hlobo lwe-bauxite lubizwa ngokuba yi-alumina ye-refractory grade.

I-Alumina clinker enemilinganiselo efanelekileyo ye-AL2O3/Fe2O3 kunye ne-AL2O3/SiO2 isetyenziselwa ukunyibilikisa i-alumina ·/Fe2O3 kunye ne-AL2O3/SiO2.

I-Bauxite clinker inokucutshungulwa ibe yi-aggregates kwaye isetyenziswe njengezinto eziphikisayo ezifana nentsimbi kunye nentlawulo yesithando somlilo. 5. Inokucutshungulwa ibe ngumgubo ocolekileyo wokusetyenziswa kwi-casting, i-refractory coatings kunye namanye amashishini. Ingasetyenziselwa ukulungiswa kwe-arhente yokucoca amanzi i-polyaluminium ferric chloride.
