Fused Cast Corundum Series refractories yog ib hom tshwj xeeb ntawm cov khoom siv refractory paub txog lawv qhov tshwj xeeb kub-kub tsis kam thiab tsis kam tiv thaiv corrosion, ua rau lawv muaj kev xaiv nrov hauv ntau daim ntawv thov kev lag luam.
Muaj pes tsawg leeg: Fused Cast Corundum Series refractories feem ntau yog tsim los ntawm high-purity alumina (Al2O3) thiab me me ntawm lwm yam additives. Cov ntsiab lus alumina feem ntau yog siab dua 95%.
Kev tsim cov txheej txheem: Cov refractories no yog tsim los ntawm cov txheej txheem uas muaj cov fusion ntawm high-purity alumina nyob rau hauv hluav taws xob arc furnaces thiab ces casting nws mus rau hauv pwm, ua raws li los ntawm kev tswj kom txias thiab annealing. Cov txheej txheem no ua rau muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom.
Hom
Fused Cast Alpha Alumina (Fused Alpha Alumina): Hom no yog tus cwj pwm los ntawm qhov siab Al2O3cov ntsiab lus thiab paub txog nws zoo heev tiv thaiv thermal shock thiab high-temperature ib puag ncig. Nws yog feem ntau siv nyob rau hauv ob sab phlu ntawm high-temperature industrial furnaces, xws li nyob rau hauv cov hlau thiab iav industries.
Fused Cast Beta Alumina (Fused Beta Alumina): Fused Beta Alumina refractories muaj ntau dua ntawm beta alumina crystals, muab kev txhim kho corrosion tiv thaiv cov ntaub ntawv alkali. Lawv feem ntau ua haujlwm hauv cov ntawv thov uas kev sib cuag nrog alkali yog ib qho kev txhawj xeeb, xws li hauv kev lag luam iav.
Fused Cast High Zirconia Corundum (Fused AZS): Hom no ua ke nrog cov ntsiab lus siab alumina thiab zirconia, muab kev tiv thaiv zoo rau ob qho tib si kub thiab tshuaj lom neeg corrosion. Fused AZS refractories feem ntau yog siv rau hauv iav rauv siv.
Cov khoom
High Refractoriness: Fused Cast Corundum Series refractories tuaj yeem tiv taus qhov kub thiab txias, ua rau lawv tsim nyog siv rau hauv cov ntaub ntawv uas lwm cov ntaub ntawv yuav yaj los yog deteriorate.
Corrosion Resistance: Cov refractories no zoo kawg nkaus tiv thaiv tshuaj corrosion, tshwj xeeb tshaj yog tawm tsam alkali cov ntaub ntawv thiab molten iav.
Tsawg porosity: Lawv muaj porosity tsawg, uas ua rau lawv impermeable rau molten hlau los yog iav thiab pab tswj lawv kev ncaj ncees nyob rau hauv hnyav ib puag ncig.
Zoo heev Thermal Shock Resistance: Qhov siab ceev thiab crystalline qauv ntawm cov refractories no pab kom lawv tiv taus kub hloov ceev yam tsis muaj cracking.
Daim ntaub ntawv: Fused Cast Corundum Series refractories pom cov ntawv thov hauv ntau qhov kev lag luam kub kub, suav nrog:
Kev tsim iav, qhov chaw uas lawv tau siv rau hauv kev tsim kho ntawm iav tank furnaces, regenerators, thiab spouts.
Kev lag luam hlau, feem ntau hauv kev tsim cov hlau zoo hauv ladles thiab tundishes.
Petrochemical thiab chemical industries rau hauv ob sab phlu reactors thiab lwm yam khoom siv kub.
Tsis yog-ferrous hlau industries, xws li aluminium ntau lawm.
Kev Sib Tw: Thaum cov refractories no muaj kev ua tau zoo, lawv zoo li yuav kim dua piv rau lwm cov ntaub ntawv refractory. Tsis tas li ntawd, kev teeb tsa thiab kev saib xyuas kom zoo yog qhov tseem ceeb los ua kom lawv lub neej ua haujlwm tau zoo.
Cov Qauv Kev Lag Luam: Ntau cov qauv thoob ntiaj teb thiab cov lus qhia muaj nyob rau kev siv Fused Cast Corundum Series refractories kom ntseeg tau tias lawv muaj kev nyab xeeb thiab siv tau zoo hauv kev lag luam sib txawv.
Fused Cast Corundum Series refractories tau txais txiaj ntsig rau lawv qhov tshwj xeeb tsis kam tiv taus kub thiab tshuaj lom neeg corrosion, ua rau lawv nyiam xaiv hauv kev lag luam uas huab cua muaj kev txhawj xeeb. Cov hom tshwj xeeb hauv cov koob raug xaiv raws li qhov yuav tsum tau ua ntawm daim ntawv thov, xws li kev xav tau kev tiv thaiv alkali lossis kub-kub stability. Txawm li cas los xij, lawv cov nqi thiab qhov tseem ceeb ntawm kev saib xyuas kom zoo yuav tsum tau txiav txim siab thaum xaiv lawv rau kev lag luam.
