Brown Fused Alumina

Brown Fused Alumina

Brown Fused Alumina (BFA) yog ib hom khoom siv hluavtaws uas muaj qhov tshwj xeeb hardness thiab durability. Nws yog tsim los ntawm smelting high-zoo bauxite nyob rau hauv hluav taws xob arc furnaces ntawm high kub. Brown Fused Alumina muaj xim av sib sib zog nqus thiab yog siv dav hauv ntau daim ntawv thov kev lag luam.

Khoom Taw Qhia

Brown Fused Alumina (BFA) yog cov khoom siv refractory ua haujlwm siab siv dav hauv kev lag luam refractory vim nws cov khoom tshwj xeeb. Cov khoom yog melted nyob rau hauv hluav taws xob arc furnaces ntawm high kub nrog raw cov ntaub ntawv xws li high-qib bauxite, carbon thiab ferrous seem kom ua tau ib tug siab refractoriness theem ntawm tshaj 1850 degree.

Ntxiv rau nws siv nyob rau hauv refractory thiab ceramics industries, BFA kuj yog siv nyob rau hauv zus tau tej cov corundum insulating cov ntaub ntawv xws li corundum lightweight bricks, corundum npuas alumina cib thiab fiber ntau. Cov ntaub ntawv no yog siv rau hauv cov phab ntsa kiln thiab cov ru tsev ntawm ntau qhov kub kub los tiv thaiv cov kiln los ntawm corrosion thiab kub kub puas.

BFA muaj cov nplej loj thiab cov tshuaj muaj pes tsawg leeg uas txawv nyob ntawm seb nws xav siv. Nws cov refractoriness siab thiab tsis kam mus rau qhov kub thiab txias ua rau nws zoo tagnrho rau kev tsim cov phab ntsa thiab qab nthab. Hauv kev lag luam ceramics, BFA yog siv rau kev tsim cov kav dej ceramic, tshwj xeeb ceramic moldings thiab electroceramic coated qhov chaw. Cov khoom no feature zoo heev corrosion kuj thiab kub stability, ua rau lawv zoo tagnrho rau high-temperature furnaces.

Qhov kub tsis kam ntawm BFA yog vim nws cov tshuaj lom neeg tshwj xeeb, uas yog tsim los ntawm alumina thiab silica oxides. Lub refractory hais kuj yog crystalline heev thiab ntom, uas pab khaws cov cua sov thiab tiv taus qhov kub siab ntawm hluav taws xob arc rauv.

Ib qho txiaj ntsig tseem ceeb ntawm kev siv BFA yog nws cov kav ntev thiab ua haujlwm ntev. BFA muaj cov thermal poob siab tsis kam thiab tsis kam tiv thaiv, ua rau nws tsim nyog rau cov ntawv thov kub kub uas yuav tsum tau ua kom ntev thiab ntev.

Hauv cov ntsiab lus, BFA yog cov khoom siv ntau yam thiab ua tau zoo refractory uas tuaj yeem siv rau hauv ntau yam lag luam xws li refractory, ceramics thiab corundum rwb thaiv tsev tsim. Nws cov tshuaj lom neeg muaj pes tsawg leeg, siab refractoriness thiab lub neej ua haujlwm ntev ua rau nws yog cov khoom siv zoo tshaj plaws rau kev siv kub.
