Tam sim no, kev siv cov ntaub ntawv nyoos hauv ntiaj teb tau tsawg zuj zus nyob hauv qee lub tebchaws tsim, thaum siv cov khoom siv high-purity hluavtaws raw khoom yog nce ntxiv. Qhov laj thawj yog tias qhov kev faib ua feem ntawm amorphous refractories siv cov khoom siv hluavtaws yog nce ntxiv, thaum cov zis ntawm av nplaum cib, siab alumina cib thiab zircon cib siv ntuj tsim cov khoom nyoos yog tsawg zuj zus. Cov neeg siv tau muaj qhov siab dua xav tau kev pab lub neej ntawm refractories. Hauv no hwm, high-purity hluavtaws raw cov ntaub ntawv muaj peev xwm ntau dua ua kom tau raws li qhov xav tau.
Ntau tus sawv cev ntawm cov khoom siv hluavtaws tau tsim tsis ntev los no:
1, Cov mullite raws clinker, uas yog ua los ntawm kaolin thiab kev lag luam alumina los ntawm ntub kev sib tsoo, lub tshuab nqus tsev extrusion, thiab tom qab ntawd calcined ntawm qhov kub siab, muaj cov khoom siv zoo thermo zoo thiab cov ntawv thov tau zoo nyob rau hauv rooj tog kiln thiab amorphous refractories.
2, Lub cordierite clinker nrog kev siv lead ua zoo tuaj yeem tau los ntawm ntub kev sib tsoo, nqus nqus thiab kub kub calcination nrog kaolin thiab Caustic magnesia ua cov ntaub ntawv raw, uas muaj daim ntawv thov zoo zeem muag hauv cov rooj tog zaum kiln.
3, Vim yog txoj kev txhim kho kom huv huv cov hlau, tsis tshua muaj cov pa roj carbon steel, muaj cov pa oxygen thiab cov hlau loj, cov refractories uas muaj calcium dawb tau them ntau dua thiab ntau dua, piv txwv li, magnesia calcium clinker.
4, Bauxite based fused corundum, bauxite based fused mullite, bauxite based fused mullite, zirconia, fused corundum, zirconia, fused magnesia thiab lwm cov khoom siv hluavtaws kuj tau txhim kho sai.
