Hlawv Nozzle Mullite Castable yog tsim los siv cov cuab yeej sib xyaw ua ke nrog siab - zoo mullite aggregates ua cov khoom siv raw, ua ke nrog corundum, silicon carbide, micro- hmoov, thiab tshwj xeeb additives.
Cov yam ntxwv tseem ceeb ntawm kev ua haujlwm
●Los ntawm kev sib koom ua ke qhov zoo ntawm ob qho tib si mullite thiab corundum, qhov no castable muaj:
●Siab refractoriness thiab zoo heev siab - kub zog
●Superior tiv thaiv rau siab - nrawm airflow yaig
●Qhov zoo tshaj plaws thermal shock tsis kam thiab tiv thaiv -spalling kev ua haujlwm
●High refractoriness nyob rau hauv load (RUL)
●Tsawg siab -kub creep rate
●Muaj zog tshuaj corrosion kuj
Tej kev siv
●Burner nozzles hauv aluminium melting furnaces
●Burner linings
●Lwm qhov siab -tej nplaim hluav taws kub- impingement Cheebtsam
Mullite castables siv rau burner nozzles nyob rau hauv aluminium melting furnaces yuav tsum tiv taus kub ntawm 1400-1500 degree. Ntxiv nrog rau qhov siab refractoriness thiab zoo heev thermal shock resistance, lub burner blocks yuav tsum muaj zog tiv thaiv siab rau siab -ceev kub gas erosion thiab plua plav-laden atmospheres. Yog li ntawd, qib siab -qib bauxite clinker thiab aluminosilicate minerals (xws li sillimanite, kyanite, thiab andalusite) nrog superior refractory khoom raug xaiv los ua thawj cov ntaub ntawv raw. Reactive -Al₂O₃ micropowder thiab silica fume yog siv los ua binders, thiab cov additives tsim nyog tau muab tso ua ke los txhim kho kev ua haujlwm.

Lub castable yog characterized los ntawm:
● siab refractoriness
● tsis kam mus rau siab - pa ya yaig
●high -kub muaj zog
● thermal shock kuj
● spalling kuj
● siab load softening kub
● low high -kub creep rate
● tshuaj tiv thaiv corrosion
● Hwm siab -purity mullite aggregates engineered tshwj xeeb rau cov ntawv siv hluav taws xob
● Tsim los tiv thaiv kev sib kis loj heev - ib puag ncig ib puag ncig
● Txo txo qhov kub tsis ua hauj lwm thaum txo qis qis thiab cov nqi kho
● Kev ntseeg tau pov thawj thoob plaws hauv cov cua kub cua sov, cov cua sov- kho qhov cub, thiab cov tshuab hluav taws xob
Lub mullite castable rau burner nozzles feem ntau yog siv nyob rau hauv:
● Muaj qhov cub hluav taws kub thiab cov khoom siv hluav taws xob
● combustion zones ntawm cua sov thiab cua sov-kho qhov cub
● Kev tua hluav taws ntawm cov teb thiab qhov av kiln
● Roj- tua, roj- tua, thiab dual - roj combustion systems
● Lwm qhov siab - qhov kub thiab txias tau raug hluav taws xob ncaj qha cuam tshuam
