Aluminium melting furnaces yog qhov tseem ceeb hauv cov txheej txheem aluminium smelting. Txawm hais tias qhov qis melting point ntawm txhuas, ntawm 660 degree, nws nthuav tawm cov teeb meem tseem ceeb hauv kev ua haujlwm ntawm lub tshuab hluav taws xob vim nws qhov kev ua haujlwm siab thiab muaj peev xwm nkag mus tau zoo. Aluminium tuaj yeem yooj yim corrode rau hauv lub qhov cub, uas cuam tshuam rau kev ua haujlwm ntawm cov khoom siv refractory, ua rau tawg thiab tev. Qhov no tuaj yeem ua rau muaj kev puas tsuaj rau lub qhov cub hauv ob sab phlu thaum lub sijhawm thiab txo nws txoj sia. Txhawm rau daws cov teeb meem no, tsis yog - nplaum aluminium castables yog ib qho kev daws teeb meem tseem ceeb rau kev txhim kho cov kav ntev thiab kev ua haujlwm ntawm aluminium melting furnaces.
Kev sib tw hauv Aluminium Melting Rauv Linings
Txawm hais tias qhov kub ntawm molten aluminium nyob rau hauv lub cub tawg tsis yog siab heev, nws muaj zog nkag tau mus rau hauv lub qhov cub hauv ob sab phlu. Cov active molten aluminium nkag mus rau hauv cov ntaub ntawv refractory los ntawm cov pores me me thiab micro- tawg. Qhov kev nkag mus no ua rau muaj tshuaj lom neeg thiab lub cev cov tshuaj tiv thaiv ntawm molten aluminium thiab cov ntaub ntawv refractory. Thaum lub sij hawm, lub hauv ob sab plhu loosens, tawg, thiab tev tawm, uas txo cov qhov cub qhov kev ua tau zoo thiab efficiency.
Tsis tas li ntawd, molten aluminium reacts chemically nrog lub refractory hauv ob sab phlu, ua rau tsim ib daim ntawv nplaum. Qhov adhesion no ua rau tsim cov txhuas tshauv thiab corundum nodules ntawm lub qhov cub hauv ob sab phlu. Raws li qhov adhesion nce, nws ua rau muaj kev puas tsuaj ntxiv ntawm cov khoom siv hauv ob sab phlu, thaum kawg cuam tshuam rau lub cub tawg qhov kev ntseeg siab. Tsis tas li ntawd, thaum cov txheej txheem xws li ntxiv cov khoom siv raw lossis tshem tawm cov slag, cov ntaub ntawv xws li bauxite lossis aluminium slag tuaj yeem cuam tshuam rau lub tshuab hluav taws xob hauv ob sab phlu, nrawm hnav thiab ua rau nws tawg.
Cov kev cov nyom no ua kom pom tseeb tias kev xaiv cov khoom siv refractory yog qhov tseem ceeb rau lub neej ntev ntawm aluminium melting furnaces. Tsis yog -stick aluminium refractory castables muab kev daws teeb meem rau cov teeb meem no los ntawm kev txo qis qhov cuam tshuam ntawm molten aluminium nkag mus, tshuaj lom neeg cov tshuaj tiv thaiv, thiab lub cev hnav ntawm lub qhov cub hauv ob sab phlu.
Yuav Ua Li Cas Tsis-Tag Aluminium Castables Ua Haujlwm
Tsis yog -stick aluminium castables ua haujlwm los ntawm kev txo qhov porosity thiab pore loj ntawm cov khoom castable. Qhov no yog ua tiav los ntawm kev siv ultra-cov hmoov hmoov zoo, uas txo cov porosity qis dua 10%. Qhov kev txo qis hauv porosity no tiv thaiv cov molten aluminium los ntawm adhering rau lub refractory hauv ob sab phlu thiab txo txoj hauv kev nkag mus. Yog li ntawd, cov khoom castable tsis lo rau molten aluminium, thiab nws tsis dai rau slag, yog li tiv thaiv kev tsim ntawm txhuas tshauv. Qhov no txhim kho tag nrho cov txiaj ntsig ntawm aluminium melting rauv thiab pab tswj qhov zoo ntawm aluminium alloy tsim.
Los ntawm kev tiv thaiv cov tshuaj tiv thaiv ntawm molten aluminium thiab lub refractory hauv ob sab phlu, tsis yog -stick aluminium castables pab kom tsis txhob impurities los ntawm kev nkag mus rau hauv lub txhuas yaj. Qhov no, nyob rau hauv lem, xyuas kom meej tias cov aluminium alloy tseem zoo. Tsis tas li ntawd, qhov txo qis hauv molten aluminium qhov adhesion rau lub qhov cub hauv ob sab phlu ua rau lub neej ua haujlwm ntawm lub cub tawg, txo qhov xav tau kev kho ntau zaus lossis hloov.
Nta ntawm Non-Tag Aluminium Refractory Castables
Tsis yog -stick aluminium castables yog tsim tshwj xeeb los ua kom tau raws li qhov xav tau ntawm aluminium melting furnaces. Lawv yog tsim los ntawm kev sib xyaw ntawm cov khoom zoo, nrog rau cov khoom tshwj xeeb- qib siab- alumina bauxite, xim av steel corundum, kyanite, alumina micro hmoov, calcium aluminate cement, silica micro hmoov, thiab lwm yam tshwj xeeb additives. Cov ntaub ntawv no tau muab sib xyaw ua ke nruj me ntsis los ua ib qho qis - cement, siab - ntom, siab - lub zog castable.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov uas tsis yog -stick aluminium castables yog lawv cov corrosion kuj siab. Lub castable yog heev resistant rau kev nkag mus ntawm molten aluminium thiab tshuaj lom neeg cov tshuaj tiv thaiv uas yuav ua rau lub cub tawg hauv ob sab phlu. Tsis tas li ntawd, lub zog ntawm cov khoom nce ntxiv thaum qhov kub thiab txias, tso cai rau cov castable ua tau zoo dua nyob rau hauv siab - qhov kub thiab txias. Lub ntim ntawm cov castable tseem nyob ruaj khov ntawm ntau qhov kub thiab txias, uas ntxiv dag zog rau nws cov kav ntev. Tsis tas li ntawd, cov ntsiab lus uas tsis muaj impurity ua kom ntseeg tau tias aluminium melts tseem tsis muaj kab mob, khaws cia kev ncaj ncees ntawm aluminium alloy.
