Khoom piav qhia
High-strength thiab hnav-resistant alumina castable refractory yog tsuas yog ua los ntawm high-strength refractory raw cov ntaub ntawv xws li tshwj xeeb-qib alumina, corundum thiab silicon carbide li aggregates thiab nplua hmoov, thiab ntxiv nrog micro hmoov. Cov khoom muaj cov yam ntxwv ntawm qhov zoo ntim stability, siab zog, zoo hnav tsis kam, thermal shock kuj, corrosion kuj, tsis muaj cracking, tsis tev, thiab lwm yam. Cov khoom yog tsuas yog siv nyob rau hauv qhov chaw ntawm industrial kilns nrog hnyav yaig thiab hnav xws li pob. rotary kilns thiab coal txhaj kav.
Daim ntawv thov ntawm alumina castable refractory
High-strength hnav-resistant alumina castable refractory yog tsuas yog siv nyob rau hauv pem hauv ntej kawg ntawm cement kiln burners. Txij li qhov no yog ib txwm ntxuav los ntawm airflow nyob rau hauv lub kiln, tshwj xeeb tshaj yog nyob rau hauv qis qis yog ntau heev ntxuav, thiab airflow nqa cov khoom siv plua plav nyob rau hauv lub kiln. Qhov cuam tshuam ntawm qhov kawg ntawm lub qhov cub yuav ua rau muaj zog yaig thiab hnav, yog li txo qhov kev pab cuam lub neej ntawm cov khoom siv. Nyob rau sab saum toj ntawm lub hau npog ntawm lub qhov cub nyob ze ntawm lub tertiary cua duct, qhov yaig ntawm plua plav airflow yog qhov hnyav heev; sab saum toj ntawm lub hauv ntej kawg ntawm lub grate txias yog tsis ncaj ncees cuam tshuam los ntawm lub rebound kub ntawm lub clinker. Kev cuam tshuam, kev ua haujlwm kub yog qhov siab thiab hloov tau zoo heev. Cov phab ntsa qis ntawm ob sab ntawm lub hauv ntej kawg ntawm lub grate txias ua rau lub siab kub clinker los ntawm lub qhov ncauj ntawm lub qhov cub rau lub sijhawm ntev, thiab raug puas tsuaj los ntawm qee yam kev ua haujlwm siab thiab kev ua noj ua haus, nrog rau cov pa cua tertiary. Lub kaum ntse ntse kuj tseem tuaj yeem hnav nyob rau hauv kev yaig ntawm plua plav airflow, yog li castables nrog zoo hnav tsis kam thiab hluav taws kub yuav tsum tau siv rau hauv cov khoom no.
