Bauxite hauv kev lag luam refractory feem ntau yog hais txog bauxite nrog calcined Alumina ntau dua 48% thiab cov ntsiab lus ferrum tsawg.
Cov ntaub ntawv refractory xa mus rau inorganic non{0}}cov ntaub ntawv hlau nrog refractoriness tshaj 1580℃.
Refractory raw khoom yog cov khoom siv raw siv los tsim cov cib refractory thiab monolithic refractories.
Hom: Muaj cov khoom sib xyaw ua ke, cov khoom sib txuas, cov khoom ntxiv, cov tshuaj tiv thaiv -oxidants thiab lwm yam.
Rau cov kev siv sib txawv, muaj cov ntaub ntawv nyoos thiab cov khoom siv hluav taws xob hnyav
Ntev Keter muab cov khoom siv dav dav, suav nrog alumina bauxite siab, Kaolin flint av nplaum, tabular alumina, alumina hmoov, xim av fused alumina, dawb fused alumina, magnesia spinel, mullite thiab lwm yam.
Lub siab bauxite clinker yog Calcined bauxite. Lub clinker yog grey, lub teeb daj thiab tsaus grey. Bauxite clinker yog cais raws li cov ntsiab lus ntawm Alumina thiab impurities xws li Ferrum, nrog rau cov khoom ntom ntom thiab dej nqus ntawm clinker.
Lub siab alumina bauxite yog tsim los ntawm hydrated alumina nrog me ntsis impurities. Calcined bauxite tau txais tom qab cov ntxhia sib cais thiab calcined nyob rau hauv teb kilns. Nws yog ib hom ntxhia uas muaj xim dawb lossis grey.Qhov ceev yog li 3.45g / cm3, hardness yog 1-3, opaque thiab nkig. High alumina bauxite yog nrog high refractoriness, nws yog insoluble nyob rau hauv dej, tab sis soluble nyob rau hauv sulfuric acid thiab sodium hydroxide tov. Nws yog tsuas yog siv rau siab alumina refractories thiab kuj ua rau fused xim av corundum.
General muaj grain loj xws li 0-1mm, 1-3mm, 3-5mm, 5-8mm, 16-30 mesh, 30-60 mesh, 120 mesh, 200 mesh, 325 mesh, los yog raws li tus neeg thov.
Cov pob dav dav yog ib tuj jumbo hnab, txheem exporting pob rau kev thauj mus los hauv hiav txwv los yog huab cua, tshwj xeeb packing yuav tsum tau.
Rau cov khoom siv refractory. Lub refractoriness ntawm siab bauxite clinker yog siab li 1780 degree, muaj zog tshuaj stability thiab zoo lub cev.
Hom
Raws li Al2O3cov ntsiab lus, muaj nruab nrab Al2O3bauxite thiab siab alumina bauxite.
