T38 siab alumina cib (hom riam)

T38, t39 siab alumina cib yog lub hauv paus tseem ceeb ntawm alumina bauxite siab; sillimanite pawg zaub mov (suav nrog kyanite, andalusite, sillimanite, thiab lwm yam); cov khoom siv hluavtaws, xws li kev lag luam alumina, hluavtaws mullite, hluav taws xob Fused corundum thiab lwm yam. Tuam Tshoj qib siab alumina banadium yog nplua nuj hauv cov peev txheej thiab zoo heev hauv kev ntxhib los mos. Cov chaw tsim khoom feem ntau xa tawm hauv Shanxi, Henan, Hebei, Guizhou, Shandong thiab lwm qhov chaw. Lub siab alumina bauxite tsim los feem ntau yog sib xyaw ntawm bauxite (Al-Al2O3 · H2O) thiab kaolinite.

Siab alumina cib yog cov khoom siv hluav taws xob nruab nrab nruab nrab nrog cov ntsiab lus alumina tsis tsawg dua 60%. Nws yog tsim thiab calcined los ntawm bauxite lossis lwm yam ntaub ntawv raw nrog cov ntsiab lus alumina siab. Peb lub Hoobkas tsim cov cib alumina siab nrog cov cua sov ruaj khov thiab ua kom rov zoo dua 1700 ℃. Kev tiv thaiv zoo slag feem ntau yog siv rau sab hauv ntawm lub qhov cub tawg, lub qhov cub tawg tawg, hluav taws xob rauv tawg, lub qhov cub tawg, lub qhov cub tawg rov qab, thiab cov qhov cub tawg. Cov khoom tseem ceeb ntawm peb lub Hoobkas yog cov cib alumina dav (piv txwv li T-lub taub hau cib) T-3 T38 T39 T19 T20 T23 T7 T52, tshwj xeeb zoo li tus cib alumina siab, tawg rauv taws tawg hluav taws cib G1 G2 G3 G4 G5 G6 rauv qhov cub koov kaum cib thiab lwm cov khoom siv hluav taws xob ua kom zoo.

1. Refractoriness: Qhov refractoriness ntawm t38 thiab t39 siab alumina cib yog siab dua li cov av nplaum cib thiab cov pob zeb ib nrab silica, mus txog 1750 ~ 1790 ℃, uas yog cov khoom siv hluav taws xob siab.

2. Thauj khoom kub kom sov: Vim tias cov khoom siv aluminium siab muaj Al2O3 siab dua, tsis muaj qhov tsis huv, thiab iav tsis tuaj yeem siv tau, qhov ua kom sov ua kom sov siab dua li cov av cib thiab cov cib alumina siab, tab sis vim tias cov mullite muaju tsis tsim cov qauv network, Qhov kub ua kom sov nyob rau hauv kev thauj khoom tseem tsis siab npaum li cov cib silica.

3. Slag tsis kam: cov av alumina siab muaj ntau dua Al2O3, uas yog ze rau cov khoom siv hluav taws xob nruab nrab, thiab tuaj yeem tiv taus cov yaig ntawm acidic slag thiab alkaline slag. Txij li nws muaj SiO2, lub peev xwm los tiv thaiv alkaline slag zoo dua li ntawm acidic slag. Tsis muaj zog Cov txheej txheem tsim tawm ntawm cov av alumina siab thiab ntau cov clinker av nplaum cib zoo sib xws. Qhov sib txawv yog qhov sib faib ntawm clinker hauv cov khoom xyaw yog siab dua, uas tuaj yeem siab li 90-95%. Cov clinker yuav tsum tau txheeb thiab sieve kom tshem cov hlau ua ntej zom, thiab qhov kub ua kom sov siab dua, xws li Ⅰ, Ⅱ siab alumina cib feem ntau yog 1500 ～ 1600 ℃ thaum lawv raug rho tawm hauv lub qhov cub. Kev xyaum tsim khoom hauv Suav teb tau ua pov thawj tias ua ntej crushing, high-alumina clinker raug xaiv nruj thiab cais, thiab khaws cia hauv qib. Kev siv bauxite clinker thiab ua ke av nplaum nplua txoj hauv kev tuaj yeem txhim kho cov khoom lag luam zoo. Feem ntau siv rau kev tsim cov cua sov tawg, cov cua sov tawg, thiab hluav taws xob cua sov ru tsev. , Lub tshuab cua sov tawg, lub tshuab cua sov rov qab, lub qhov cub tawg rov qab, thiab lwm yam.

High-alumina refractory cib, uas yog, cov khoom siv aluminium silicate refractory nrog cov ntsiab lus alumina ntau dua 48%. Nws yog tsim thiab calcined los ntawm bauxite lossis lwm yam ntaub ntawv raw nrog cov ntsiab lus alumina siab. Siab thermal stability, refractoriness saum toj no 1770 ℃. Kev tiv thaiv slag zoo dua.

Feem ntau muab faib ua plaub pawg:

Chav Kawm I: Al2O3 cov ntsiab lus ≥75%;

Chav Kawm Ⅱ: Al2O3 cov ntsiab lus 60%~ 75%;

Chav Kawm Ⅲ: Cov ntsiab lus Al2O3 yog 48%~ 60%;

Cov chav kawm tshwj xeeb: AL2O3 cov ntsiab lus ≥80%.

Nws kuj tseem tuaj yeem raug cais raws li nws cov muaj pes tsawg leeg, feem ntau faib ua tsib pawg: qis mullite (sillimanite), mullite, mullite-corundum, corundum-mullite thiab corundum.
