Siab alumina cib melting taw tes

High alumina cib yog ib hom refractory cib. Raws li cov ntsiab lus alumina, siab alumina cib muab faib ua tshwj xeeb siab alumina cib, thawj, theem nrab thiab qib siab siab alumina cib. Cov ntsiab lus alumina ntawm peb lub siab alumina cib yog txawv. Qhov siab dua cov ntsiab lus ntawm aluminium, tsawg dua lwm yam impurities, tsawg dua lub iav lub cev uas yooj yim rau yaj, thiab qhov sib txawv softening kub nyob rau hauv load.

1. Tshwj xeeb high-alumina bricks: cov ntsiab lus ntawm alumina yog ntau dua 80%, thiab cov load softening kub yog txog 1550 ° C.

2. Thawj qib siab alumina cib: Cov ntsiab lus alumina yog ntau dua 75%, thiab cov load softening kub yog txog 1510 ℃.

3. Secondary siab alumina cib: Cov ntsiab lus alumina yog ntau tshaj 65%, thiab cov load softening kub yog txog 1460 ℃.

4. Peb-theem high-alumina cib: cov ntsiab lus ntawm txhuas yog ntau tshaj 55%, thiab softening kub nyob rau hauv load yog hais txog 1420 ℃.
