Cement rotary kiln refractory cibyog ib qho khoom siv tseem ceeb rau kev tsim cov cement rotary kilns uas kub heev. Ua ib qho tseem ceeb ntawm kev tiv thaiv ntawm cov kab ke kilns, nws cuam tshuam ncaj qha rau kev ruaj khov ntawm cov khoom siv, kev siv hluav taws xob zoo thiab kev siv lub neej tag nrho. Cov cement kilns ua haujlwm hauv cov xwm txheej hnyav nrog kev kub siab tas li, kev hloov pauv thermal ntau zaus, kev puas tsuaj ntawm lub tshuab thiab kev xeb alkali, ua rau cov cib refractory zoo tseem ceeb rau kev tsim cov clinker ruaj khov.
Cov cib ua haujlwm hnyav xav tau kev ua haujlwm zoo dua los ntawm cov cib refractory. Cov khoom zoo tshaj plaws muaj kev tiv taus kub zoo heev, ruaj khov rau qhov kub tshaj 1350 ° C yam tsis muaj kev hloov pauv lossis kev puas tsuaj ntawm cov qauv. Lawv kuj muab kev tiv thaiv thermal shock zoo heev, tiv taus cov kab nrib pleb thiab spalling los ntawm kev hloov pauv kub ntau zaus thaum lub sijhawm pib lub cub tawg, kaw thiab ua haujlwm txhua hnub.
Cov cib refractory no muaj cov tshuaj tiv thaiv xeb zoo tiv thaiv cov tshuaj alkaline, cov tshuaj sulfur thiab clinker slag tsim tawm hauv calcination, zoo tiv thaiv kev puas tsuaj ntawm cov ntaub thiab kev laus ua ntej lub sijhawm. Lawv lub zog siab thiab kev hnav tsis kam tiv taus kev sib txhuam thiab kev nyuaj siab los ntawm cov khoom siv raw thiab clinker, ua kom ntseeg tau tias lub cub tawg ua haujlwm ntev thiab ruaj khov.
Cov cib refractory sib txawv yog tsim los rau cov xwm txheej ua haujlwm ntawm lub qhov cub segmented.
Cov cib ua los ntawm cov khoom siv alumina siab haum rau thaj chaw ua ntej thiab thaj chaw hloov pauv uas muaj qhov porosity tsawg, lub zog kub siab thiab kev txuag nyiaj.
Cov cib Magnesia-spinel zoo tagnrho rau thaj chaw kub hnyiab vim muaj kev ruaj khov zoo heev thiab tiv taus alkali.
Cov cib tiv thaiv kev tev tawm raug siv rau hauv thaj chaw uas hloov pauv qhov kub kom tsis txhob tev tawm thiab ua kom lub txheej siv tau ntev.
Cov cib ua los ntawm cov cement rotary kiln zoo tshaj plaws tsim kom muaj txiaj ntsig zoo rau kev lag luam rau cov nroj tsuag cement.
Lawv txo qhov poob cua sov, ua kom muaj kev ua haujlwm thermal zoo dua 5% -10% thiab txo cov nqi roj. Lawv lub zog ruaj khov zoo txo qhov zaus hloov thiab kev saib xyuas, txo qhov sijhawm tsis ua haujlwm ntawm lub qhov cub thiab txhim kho kev ua haujlwm zoo heev.
Hauv ntej, cov cib refractory zoo tshaj plaws yog qhov tseem ceeb rau kev tsim cov cement zoo tshaj plaws. Lawv qhov ruaj khov thiab ruaj khov thaum kub thiab txias, tiv taus corrosion thiab ua kom muaj kev nyab xeeb, ua haujlwm tau zoo thiab pheej yig ntawm cov cement rotary kilns.
Nrhiav cov cib ua los ntawm cov cement rotary kiln uas ruaj khov thiab ua tau zoo?
Peb muab cov kev daws teeb meem refractory uas tsim tshwj xeeb rau ntau hom qauv cub tawg thiab cov xwm txheej ua haujlwm. Peb cov khoom siv dav dav hauv cov chaw tsim khoom cement thoob ntiaj teb nrog cov khoom zoo ruaj khov, cov nqi sib tw thiab kev txhawb nqa kev tshaj lij.
Tiv tauj peb hnub no kom tau txais cov khoom lag luam dawb, cov kev daws teeb meem tshwj xeeb thiab cov lus hais tshiab tshaj plaws ntawm lub Hoobkas.
