Dab tsi yog qhov txawv ntawm raw bauxite thiab siav bauxite?

Kuv lub teb chaws yog ib tug loj tsim thiab exporter ntawm refractory cov ntaub ntawv, nrog refractory cov ntaub ntawv tso zis accounting rau 65% ntawm lub ntiaj teb no tag nrho. Bauxite yog ib qho ntawm cov khoom siv tseem ceeb rau kev tsim cov khoom siv refractory. Bauxite hauv kev lag luam refractory feem ntau yog hais txog bauxite ore nrog cov ntsiab lus calcined Al2O3 ntawm ≥48% thiab cov ntsiab lus Fe2O3 tsawg. Raws li ib qho tseem ceeb raw khoom rau cov ntaub ntawv refractory, bauxite occupies ib irreplaceable txoj hauj lwm.

Lub ntsiab sib txawv ntawm raw bauxite thiab siav bauxite yog ntau hom pob zeb: raw khoom yog kaolinite thiab diaspore, thiab clinker yog mullite. Bauxite clinker, hu ua cov khoom siv alumina siab, ntau lub siab alumina cib ua los ntawm nws cov clinker yog cov khoom siv hluav taws xob los yog cov khoom siv los tiv thaiv cov khoom siv dav siv hauv kev lag luam metallurgical thiab lwm yam lag luam, tshwj xeeb tshaj yog siv rau sab saum toj ntawm hluav taws xob furnaces, blast furnaces thiab kub blast furnaces. . Cov nyhuv refractory yog qhov tseem ceeb heev, thiab nws cov kev ua tau zoo dua li cov av nplaum zoo tib yam refractory cib. Bauxite: ib qho txhuas oxide ore nrog cov tshuaj formula Al2O3.H2O, Al2O3.3H2O thiab ib qho me me ntawm FE2O3.SiO2. Nws feem ntau daj mus rau xim liab vim nws muaj hlau oxide, yog li nws tseem hu ua "hlau vanadium av". Nws yog lub ntsiab raw khoom rau aluminium smelting. Bauxite tau muab faib ua qib metallurgical, qib tshuaj, qib refractory, qib sib tsoo, qib cement, thiab lwm yam raws li nws siv.

Siv los ua cov ntaub ntawv refractory, hom bauxite no hu ua refractory qib alumina.

Alumina clinker nrog qhov tsim nyog ntawm AL2O3 / Fe2O3 thiab AL2O3 / SiO2 yog siv los yaj alumina · / Fe2O3 thiab AL2O3 / SiO2.

Bauxite clinker tuaj yeem ua tiav rau hauv cov khoom sib xyaw thiab siv los ua cov ntaub ntawv refractory xws li steel thiab qhov cub. 5. Nws tuaj yeem ua tiav rau hauv cov hmoov zoo siv rau hauv casting, refractory coatings thiab lwm yam lag luam. Nws kuj tseem siv tau rau kev npaj dej purification tus neeg saib xyuas polyaluminum ferric chloride.
