1. Muaj qhov sib txawv ntawm qib tshwj xeeb qib siab alumina cib thiab zoo tib yam siab aluminium cib nyob rau hauv cov nqe lus ntawm kev ua tau zoo, ntsuas thiab kev siv.
Qhov sib txawv tseem ceeb yog qhov zoo ntawm lub cev. Cov cib tshwj xeeb yog ua los ntawm cov khoom siv tshwj xeeb-qib bauxite raw khoom. Cov ntsiab lus AL2O3 ntawm cov khoom siv tshwj xeeb qib yog ntau dua 85% thiab qhov ceev yog 2.8g / cm3. AL2O3 ntawm cov khoom siv raw zoo tib yam yog 75% thiab qhov ceev yog nyob ib puag ncig 2.6. Yog li ntawd, ob qho khoom siv raw muaj qhov sib txawv loj ntawm qhov ntom ntawm cov khoom tsim.
2. Muaj qhov sib txawv ntawm compressive zog thiab hnav tsis kam.
Qhov hluav taws kub ntawm cov cib zoo tib yam yog 1780 degree. Lub refractoriness ntawm cov cib qib tshwj xeeb yog 1820 degree, thiab qhov kub ntawm qhov hluav taws kub yog li 30 degree siab dua li cov cib zoo tib yam. Lub neej kev pab cuam ntawm qib tshwj xeeb qib siab alumina cib yog ob zaug ntawm cov zoo tib yam siab aluminium cib. Crystal theem ntawm siab alumina refractory cib yog tsim los ntawm mullite, iav theem thiab corundum theem. Qhov siab dua cov ntsiab lus ntawm aluminium, qhov ntau dua qhov kev faib ua feem ntawm corundum theem. Yog li ntawd, kuj tseem muaj qhov sib txawv loj hauv compressive zog thiab hnav tsis kam.
3. Qhov sib txawv ntawm load softening kub
Kuj tseem muaj qhov sib txawv ntawm qhov ntsuas kub ntawm qhov sib txawv ntawm cov qib tshwj xeeb cib thiab cov cib zoo tib yam. Txij li thaum qhov hluav taws kub kub sib txawv li ntawm 30 degree, lub load softening kub kuj txawv los ntawm ntau tshaj 30 degree. Tom qab ntawd muaj qhov kub thiab txias siv. Kev siv kub ntawm qhov zoo tib yam siab alumina cib yog muab faib ua peb qib sib txawv ntawm high-alumina cib: peb, ob thiab ib qho. Kev siv kub yog nyob nruab nrab ntawm 1250-1450 degree feem, thaum siv kub tshwj xeeb siab alumina refractory bricks yog 1500. degree .
4. Puas yog lawv muaj zog hauv slag tsis kam?
Cov txheej txheem kub kub, thermal shock stability thiab slag tsis kam ntawm cov qib tshwj xeeb cib kuj yog 1-2 zaus siab dua li cov khoom siv high-alumina cib. Ordinary high-alumina bricks tsis muaj zog slag tsis kam, thaum tshwj xeeb-qib cib muaj zog slag tsis kam, thiab lawv qaug zog tiv thaiv ntawm kub kub yog tshwj xeeb yog muaj zog.
Piv txwv li, thauj tog rau nkoj cib yog ib qho piv txwv. Cov ntsiab lus aluminium siab thiab lub zog zoo tsis yog qhov tsim nyog rau kev siv. Thauj tog rau nkoj cib nrog cov ntsiab lus txhuas ntawm li 55% muaj qhov hloov tau zoo. Yog tias cov ntsiab lus aluminium siab dhau lawm, lub zog yuav siab dhau, uas yuav ua rau cov castable ntau dua tuaj yeem tawg.
Nyob rau hauv luv luv, txawm hais tias nws yog ib tug tshwj xeeb siab alumina cib los yog ib tug zoo tib yam cib, koj yuav tsum to taub qhov kev ua tau zoo ntawm txhua qib los xaiv cov qib sib txawv ntawm high-alumina cib kom tau raws li ntau yam kub thiab corrosion tej yam kev mob.
