Dab tsi yog qhov txawv ntawm siab alumina cib thiab av nplaum cib
Dab tsi yog qhov txawv ntawm cov siab alumina cib thiab av nplaum cib
Lub teeb yuag high-alumina cib feem ntau siv high-alumina bauxite clinker ntxiv rau me me ntawm av nplaum. Tom qab hauv av, lawv tau nchuav thiab zoo li cov av nkos los ntawm cov txheej txheem roj los yog ua npuas dej, thiab raug rho tawm haujlwm ntawm 1300-1500 ° C. Qee zaum muaj alumina tuaj yeem siv los hloov ib feem ntawm bauxite clinker. Nws yog siv rau hauv ob sab phlu thiab tshav kub rwb thaiv tsev txheej ntawm masonry kilns, raws li zoo raws li qhov chaw uas tsis corroded thiab scoured los ntawm muaj zog high-temperature molten cov ntaub ntawv. Thaum nyob rau hauv kev sib cuag ncaj qha nrog cov nplaim taws, qhov kub ntawm qhov chaw yuav tsum tsis txhob siab tshaj 1350 ℃.
Lub teeb yuag av nplaum cib, thermal rwb thaiv tsev refractories xa mus rau refractories nrog siab porosity, tsawg bulk ceev thiab tsawg thermal conductivity. Thermal rwb thaiv tsev refractories tseem hu ua lub teeb refractories, uas muaj xws li thermal rwb thaiv tsev refractory khoom, refractory fibers thiab refractories Fiber khoom. Thermal rwb thaiv tsev refractories yog tus cwj pwm los ntawm siab porosity, feem ntau 40% -85%; tsawg qhov ntom ntom tsawg dua 1.5g / cm3; Tsawg thermal conductivity, feem ntau tsawg dua 1.0W (mK). Nws ua raws li cov khoom siv hluav taws xob rwb thaiv tsev rau cov khoom siv hluav taws xob, uas tuaj yeem txo qhov kub ntawm qhov cub, txuag hluav taws xob, thiab txo cov khoom siv thermal. Thermal rwb thaiv tsev refractories muaj tsis zoo txhua yam lub zog, puas kuj thiab slag corrosion kuj, thiab tsis haum rau lub load-bearing qauv ntawm lub kiln thiab ncaj qha kev sib cuag nrog slag, nqi, molten hlau thiab lwm yam.
Muaj qhov sib txawv ntawm cov ntsiab lus ntawm txhuas, chav tsev qhov hnyav, siv kub, thiab xim. Piv txwv li: 75 siab alumina cib thiab 43 av nplaum cib, 75 units hnyav tshaj 4.5kg. 43 ntawm txog 3.65kg, kev siv kub ntawm 75 siab alumina yog hais txog 1520, 43 ntawm bricks yog hais txog 1430, xim yog 75 dawb, thiab 43 yog loess. Hauv luv, qhov sib txawv yog loj.
