High-alumina Hluav Taws Cib

High-alumina cib yog ib hom khoom siv refractory, thiab lub ntsiab ntawm cov cib refractory no yog Al2O3. Yog hais tias cov ntsiab lus ntawm Al2O3 siab tshaj 90%, nws yog hu ua corundum bricks.raws li cov ntsiab lus ntawm Al2O3 nyob rau hauv high-alumina bricks, nws feem ntau muab faib ua peb qib: Class I. - Al2O3 ntsiab lus> 75%, Class II - Al2O3 cov ntsiab lus yog 60 ~ 75%, Chav Kawm III - Al2O3 cov ntsiab lus yog 48 ~ 60%.

Cov khoom siv nruab nrab refractory nrog cov ntsiab lus alumina ntau dua 48%. Nws yog tsim thiab calcined los ntawm bauxite los yog lwm yam ntaub ntawv raw nrog siab alumina cov ntsiab lus. Siab thermal stability, refractory saum 1770 degree. Nws muaj qhov zoo slag tsis kam thiab siv rau hauv ob sab steelmaking hluav taws xob furnaces, iav furnaces, cement rotary furnaces, thiab lwm yam.

Crafting txheej txheem
Cov txheej txheem ntau lawm ntawm high-alumina hluav taws cib thiab ntau-clinker av nplaum cib zoo ib yam, qhov sib txawv yog qhov feem ntawm clinker hauv cov khoom xyaw yog siab dua, uas tuaj yeem siab li 90 ~ 95%, thiab clinker yuav tsum tau muab qhab nia. thiab soj ntsuam ua ntej crushing, thiab qhov hluav taws kub kub yog siab dua, xws li I., II. thiab lwm cov high-alumina cib feem ntau yog 1500 ~ 1600 degree thaum raug rho tawm haujlwm hauv qhov cub.

Tuam Tshoj txoj kev siv ntau lawm tau ua pov thawj tias high-alumina clinker yog nruj me ntsis sorted thiab graded ua ntej crushing, thiab cov khoom zoo tuaj yeem txhim kho los ntawm kev siv cov kev sib tsoo zoo ntawm bauxite clinker thiab cov av nplaum ua ke.

High-alumina cib nta:

a. Refractoriness
Lub refractory degree ntawm high-alumina refractory cib yog siab dua li cov av nplaum cib thiab semi-silica cib, ncav cuag 1750 ~ 1790 degree, uas yog qib high-qib refractory khoom.
b. Load softening kub
Vim tias Al2O3 nyob rau hauv high-alumina cov khoom yog siab, lub impurity yog tsawg, thiab lub fusible iav lub cev yog tsawg, yog li lub load softening kub yog siab tshaj li cov av nplaum cib, tab sis vim hais tias mullite crystals tsis tsim ib tug network qauv, lub load. softening kub tseem tsis siab npaum li cov silica bricks.
c. Slag kuj
Muaj ntau Al2O3 nyob rau hauv high-alumina cib, uas yog nyob ze rau nruab nrab refractories, thiab muaj peev xwm tiv taus qhov yaig ntawm acid slag thiab alkaline slag, vim nws muaj SiO2, yog li lub peev xwm los tiv thaiv alkaline slag yog qaug zog dua li cov kua qaub slag.
siv

Kev siv ntawm High-alumina cib

Nws yog tsuas yog siv rau masonry moj tej tawg rauv, kub moj tej tawg rauv, hluav taws xob rauv saum, moj tej tawg rauv, reverberatory rauv, teb kiln hauv ob sab phlu. Tsis tas li ntawd, high-alumina refractory bricks kuj tau dav siv los ua qhib-hearth regenerative lattice bricks, ntsaws taub hau rau cov tshuab pouring, nozzle cib, thiab lwm yam. Txawm li cas los xij, tus nqi ntawm high-alumina hluav taws cib yog siab dua li cov av nplaum cib, yog li ntawd. tsis tas yuav siv high-alumina cib qhov twg av nplaum cib tuaj yeem ua tau raws li qhov yuav tsum tau ua.
