Graphite Degassing Rotors yog tsim los qhia inert gases, xws li argon los yog nitrogen, rau hauv molten hlau kom tshem tawm hydrogen thiab lwm yam impurities. Lub rotor spines ntawm high speeds, tsim ib tug vortex uas disperses cov pa npuas thoob plaws hauv lub molten hlau. Raws li cov pa npuas nce mus rau saum npoo, lawv nqa cov impurities nrog lawv, zoo degassing cov hlau.
Cov kev xav tau ntawm Magnesium Degassing
Magnesium yog cov hlau hnyav uas muaj zog zoo heev - rau - qhov hnyav piv, ua rau nws muaj kev xaiv nrov hauv ntau yam lag luam, suav nrog tsheb, aerospace, thiab hluav taws xob. Txawm li cas los xij, magnesium yog reactive heev thiab muaj affinity siab rau hydrogen, uas tuaj yeem ua rau porosity thiab lwm yam tsis xws luag hauv cov khoom kawg. Yog li, degassing yog ib kauj ruam tseem ceeb hauv cov txheej txheem magnesium smelting kom ntseeg tau tias cov hlau zoo.
Cov txheej txheem degassing rau magnesium feem ntau yog siv cov roj inert, xws li argon lossis nitrogen, tshem tawm hydrogen los ntawm cov hlau molten. Cov roj yog nkag mus rau hauv cov hlau molten siv lub degassing rotor, uas yuav tsum muaj peev xwm tiv taus qhov kub thiab txias ntawm molten magnesium. Tsis tas li ntawd, lub rotor yuav tsum muaj peev xwm tsim kom muaj qhov sib txawv ntawm cov pa roj npuas thoob plaws hauv cov hlau molten kom ua tau zoo degassing.
Puas yog Graphite Degassing Rotor siv tau rau hauv Magnesium Degassing?
Cov lus teb yog yog, Graphite Degassing Rotor tuaj yeem siv rau hauv magnesium degassing. Graphite muaj ntau yam khoom uas ua rau nws haum rau daim ntawv thov no. Ua ntej, graphite muaj cov ntsiab lus siab melting, uas tso cai rau nws tiv taus qhov kub siab ntawm molten magnesium. Thib ob, graphite tiv taus cov tshuaj corrosion, uas tiv thaiv lub rotor los ntawm corrosive xwm ntawm molten magnesium. Thib peb, graphite muaj cov coefficient tsawg ntawm kev sib txhuam, uas txo qhov hnav thiab tsim kua muag ntawm lub rotor thaum ua haujlwm.
Txawm li cas los xij, muaj qee qhov kev xav thaum siv Graphite Degassing Rotor hauv magnesium degassing. Ib qho ntawm cov kev sib tw tseem ceeb yog kev ua haujlwm ntawm magnesium nrog graphite. Magnesium tuaj yeem cuam tshuam nrog graphite ntawm qhov kub thiab txias, tsim magnesium carbide, uas tuaj yeem ua rau lub rotor degrade thaum lub sijhawm. Txhawm rau txo qhov teeb meem no, graphite rotor tuaj yeem coated nrog txheej tiv thaiv, xws li silicon carbide lossis boron nitride, los tiv thaiv cov tshuaj tiv thaiv ntawm magnesium thiab graphite.
Lwm qhov kev txiav txim siab yog qhov tsim ntawm lub rotor. Lub rotor yuav tsum tau tsim los tsim kom muaj qhov sib txawv ntawm cov pa roj npuas thoob plaws hauv cov hlau molten kom ua tau zoo degassing. Qhov no tuaj yeem ua tiav los ntawm kev siv lub rotor nrog cov duab tshwj xeeb thiab cov hniav tsim. Tsis tas li ntawd, lub rotor yuav tsum muaj peev xwm tig ntawm qhov nrawm los tsim kom muaj lub zog vortex uas tuaj yeem tawg cov pa npuas thoob plaws hauv cov hlau molten.
Qhov zoo ntawm Kev Siv Graphite Degassing Rotor hauv Magnesium Degassing
Muaj ntau qhov zoo ntawm kev siv Graphite Degassing Rotor hauv magnesium degassing.
