Ukuhlelwa kwe-bauxite

I-Bauxite, eyaziwa ngokuba yi-bauxite okanye i-bauxite, ikakhulu yenziwe nge-aluminium oxide kwaye iqulethe ukungcola. I-Bauxite inokwakheka okuntsonkothileyo kakhulu kwaye ligama eliqhelekileyo leentlobo ngeentlobo ze-alumina ores ene-hydrous enemvelaphi yokwakheka komhlaba.

Ngokutsho kokusetyenziswa kwe-bauxite, ihlulwe kwibakala le-metallurgical, ibakala lekhemikhali, ibakala le-refractory, ibakala lokugaya, ibakala le-samente, njl njl. Isetyenziselwa ukwenza izinto eziphikisayo, olu hlobo lwe-bauxite lubizwa ngokuba yi-alumina ye-refractory grade. I-Bauxite clinker enemilinganiselo efanelekileyo ye-AL2O3/Fe2O3 kunye ne-AL2O3/SiO2 isetyenziselwa ukunyibilikisa i-alumina.

1. Ubushushu obuphezulu be-refractory, ukuzinza okuqinileyo kwe-thermal, kwaye akukho kuqhekeka. Isanti ye-aluminiyam ye-mullite yimveliso esekwe kwi-aluminiyam-silicon. Emva kokubala, i-refractoriness yayo kunye nokuzinza kwe-thermal vibration kukhulu kakhulu kunesanti ye-quartz kunye nesakhiwo sesigaba se-crystal esakhiwe nge-silicon enye ye-crystal. Ayimanziswa lula yintsimbi engamanzi ukwenza ukunyibilika okuphantsi, okunokoyisa Isanti yeQuartz inomlinganiso omkhulu wokwandiswa kwe-thermal kunye nesivuno esibi ngexesha lokujiya, okukhokelela kwiziphene ezifana nokuchaneka kokuphosa okuphantsi kunye nokuncamathela kwesanti.

2. Ukuhlelwa kwamasuntswana ahlukeneyo, ukuphefumla okungcono. Isanti ye-Foundry igalelwe yi-Raymond mill kwaye ixutywe ngokwe-particle gradation ethile ngexesha lokuvelisa ukuphucula umoya wepeyinti. Ukongeza, iimveliso ezicutshungulwa ziibhola zebhola, iincinci zesanti ezigayiweyo ezicutshungulwa yiRaymond mills zilawulwa ngcono, kwaye ubungakanani be-bauxite clinker bunzululwazi ngakumbi.

3. Iingubo zine-fusion ephezulu, amandla aphezulu kunye nokudilika okulula. Iingubo ezilahlayo ezahlukeneyo zisebenzisa iimveliso ze-aluminium-silicon clinker, i-foam elahlekileyo ye-bauxite clinker powder ecolekileyo, ngokwemigangatho eyahlukeneyo yamasuntswana ukusuka ngaphakathi ngaphandle. Ukudibanisa ukusuka kwi-coarse ukuya kwi-coarse kubangela iqondo eliphezulu lokudibanisa phakathi kweengubo; lo gama ukwandisa amandla ukutyabeka kunye nokumelana ukhukuliseko ukuthintela iingxaki ezifana nokudilika, kwakhona kulula demould. Kwaye i-bauxite mullite yinto engathathi hlangothi, kwaye i-bauxite clinker ingasetyenziselwa zombini izibophelelo ze-asidi kunye ne-alkali.
