Ndeupi musiyano uripo pakati pebauxite mbishi uye yakabikwa bauxite?
Nyika yangu inogadzira uye mutengesi mukuru wezvinhu zvinoramba, zvine refractory zvinhu zvinobuda zvinoverengera makumi matanhatu neshanu muzana epasi rose. Bauxite ndeimwe yemhando huru yezvigadzirwa zvekugadzira refractory zvinhu. Bauxite muindasitiri yerefractory inowanzoreva bauxite ore ine calcined Al2O3 yemukati ye ≥48% uye yakaderera Fe2O3 yemukati. Sechinhu chakakosha mbishi yezvinhu zvinoramba, bauxite inotora chinzvimbo chisingachinjike.
Musiyano mukuru pakati pebauxite mbishi uye yakabikwa bauxite akasiyana mamineral marudzi: mbishi zvinhu ndeye kaolinite uye diaspore, uye clinker is mullite. Bauxite clinker, inonzi yakakwira alumina zvinhu, zvidhinha zvakasiyana-siyana zvealuminium zvakakwirira zvakagadzirwa kubva kune clinker zvigadziriso kana anti-corrosion zvinhu zvinoshandiswa zvakanyanya muindasitiri yesimbi uye mamwe maindasitiri, kunyanya anoshandiswa pamusoro pemavira emagetsi, mavira anoputika uye moto unopisa moto. . Iyo refractory mhedzisiro yakakosha, uye kuita kwayo kuri nani pane zvakajairika ivhu refractory zvidhinha. Bauxite: an aluminium oxide ore ine kemikari formula Al2O3.H2O, Al2O3.3H2O uye shoma shoma yeFE2O3.SiO2. Inowanzoita yero kusvika kutsvuku nekuti ine iron oxide, saka inonziwo "iron vanadium ivhu". Ndicho chikuru mbishi zvinhu kuti aruminiyamu smelting. Bauxite yakakamurwa kuita metallurgical giredhi, kemikari giredhi, refractory giredhi, kukuya giredhi, simende giredhi, etc. maererano kushandiswa kwayo.
Inoshandiswa kugadzira zvinhu zvinoramba, iyi mhando ye bauxite inonzi refractory giredhi alumina.
Alumina clinker ine zvikamu zvakakodzera zve AL2O3/Fe2O3 uye AL2O3/SiO2 inoshandiswa kunyungudutsa alumina ·/Fe2O3 uye AL2O3/SiO2.
Bauxite clinker inogona kugadziriswa kuita aggregates uye inoshandiswa sezvinhu zvinoramba zvakaita sesimbi nechoto chaji. 5. Inogona kugadziriswa kuita poda yakatsetseka kuti ishandiswe mukukanda, refractory coatings uye mamwe maindasitiri. Inogona zvakare kushandiswa kugadzirira mvura yekuchenesa mumiriri polyaluminium ferric chloride.
