Bauxite yog ua lub luag haujlwm tseem ceeb ua cov khoom siv tseem ceeb hauv cov ntaub ntawv kev lag luam refractory, tshwj xeeb tshaj yog nyob rau hauv silicon-txhuas cov ntaub ntawv rank. Hauv Suav teb, Bauxite feem ntau muab faib rau Shanxi, Henan, Guizhou thiab lwm qhov chaw. Shanxi thiab Henan ua ke account rau feem ntau ntawm Bauxite cov peev txheej.
Shanxi Bauxite khaws nyiaj rau txog li 43% ntawm lub teb chaws tag nrho. Nws yog tus cwj pwm siab silicon thiab aluminium cov ntsiab lus, poov xab, cov ntsiab lus ntawm al2o3 tuaj yeem ncav ntau dua 90%, nrog cov impurity cov ntsiab lus xws li FE2O3 thiab TIO2. Nws qhov refactoriness muaj txog li 1780 degree, siab bulk density thiab cov kev ua kom muaj zog kub siab thiab zoo creep resistance. Nws yog qhov tsim nyog dua rau kev tsim cov khoom nruab nrab thiab cov khoom siv refractory, tshwj xeeb tshaj yog cov khoom lag luam.
Henan Bauxite muaj peev xwm yog thib ob tsuas yog rau Shanxi, nrog Al2O3 cov ntsiab lus ntawm {2}}%. Cov ntsiab lus silicon feem ntau muaj siab, thiab cov piv txwv-sixium yog qhov tsis muaj tsawg, uas muaj qee qhov cuam tshuam rau kev ua tau kub siab. Kev ua kom ua tsis tau zoo kuj yog qhov zoo, tab sis cov ntim ruaj khov tom qab kev kho dua yog me ntsis qis dua. Cov ntsiab lus FE2O3 yog qhov tseem ceeb, feem ntau tswj hwm thaum nyob ib ncig ntawm 2%. Hauv daim ntawv thov ntawm cov ntaub ntawv refractory, lub slag tiv taus yog qhov tsis zoo me ntsis. Qhov ntau ntawm cov khoom zoo bauxite nrog cov ntsiab lus zoo dua qub yog qhov me me. Nws yog qhov tsim nyog dua rau kev tsim cov ntaub ntawv nruab nrab thiab tsawg dua li qib ob Cib Cib, thiab lwm yam Kev Lag Luam High Alumite yuav tsum tau tswj hwm kom zoo; Txwv tsis pub, nws yuav yog counterproductive.
Thaum xaiv Bauxite, peb yuav tsum tsis txhob dig muag rau tus nqi, lwm qhov khoom tseem ceeb yog tias cov khoom lag luam haum rau cov haujlwm ua haujlwm yuav tsum tau xaiv raws li kev siv cov xwm txheej.
