Cov Cib Refractory Alumina Siab
Cov cib refractory siab aluminayog ib hom khoom siv aluminosilicate refractory nrog alumina ua lub ntsiab tivthaiv. Nrog cov ntsiab lus alumina tshaj 48%, lawv raug cais ua cov khoom siv refractory nruab nrab, ua los ntawm bauxite lossis lwm yam khoom siv raw nrog cov ntsiab lus alumina siab los ntawm kev molding thiab calcination.
Kev faib tawm:
Raws li cov ntsiab lus alumina, lawv muab faib ua peb qib:
Qib 1: cov cib uas muaj alumina ntau (Cov ntsiab lus Al₂O₃ > 75%)
Qib 2: cov cib uas muaj alumina ntau (Al₂O₃ cov ntsiab lus: 60% ~ 75%)
Qib 3: cov cib uas muaj alumina ntau (Al₂O₃ cov ntsiab lus: 48% ~ 60%)
Txheej Txheem Tsim Khoom:
Cov txheej txheem tsim cov cib uas muaj alumina siab zoo ib yam li cov cib uas muaj ntau lub clinker hluav taws. Qhov feem pua ntawm clinker hauv qhov sib tov tuaj yeem siab txog 90% ~ 95%. Ua ntej tsoo, cov clinker yuav tsum tau muab qib, cais thiab siev kom tshem tawm hlau. Qhov kub ntawm kev hlawv yog qhov siab heev; Qib 1 thiab Qib 2 cov cib uas muaj alumina siab feem ntau raug hlawv ntawm 1500 ℃ ~ 1600 ℃ hauv qhov cub qhov av.
Cov Khoom Siv Physicochemical:
1. Kev ua kom tsis kub
Nws tuaj yeem tiv taus qhov kub siab tshaj 1770 ℃, feem ntau yog txij li 1750 ℃ txog 1790 ℃. Qhov refractoriness nce nrog rau qhov nce ntawm alumina cov ntsiab lus.
2. Qhov Kub Uas Ua Rau Lub Cev Mos
Feem ntau nws yog 1420 ℃ ~ 1530 ℃. Vim yog cov ntsiab lus alumina siab, cov ntsiab lus tsis muaj kuab paug thiab tsawg kawg nkaus ntawm cov iav fusible, nws qhov kub thiab txias ntawm qhov hnyav yog siab dua li ntawm cov av nplaum hluav taws.
3. Lub zog txias Compressive
Lub zog compressive txias ntawm Qib 1 high-alumina cib (LZ-80) yog ≥ 70 MPa, thaum ntawm Qib 3 high-alumina cib (LZ-48) yog ≥ 40 MPa.
4. Kev Tiv Thaiv Slag
Cov cib uas muaj alumina siab nyob ze rau cov khoom siv refractory nruab nrab, uas tuaj yeem tiv taus kev yaig ntawm ob qho tib si acidic thiab alkaline slags, tab sis lawv qhov kev tiv thaiv rau alkaline slags yog qhov tsis muaj zog dua li qhov rau acidic slags.
5. Pom tseeb porosity
Qhov pom tseeb porosity ntawm Qib 1 high-alumina cib yog ≤ 21%, thiab ntawm Qib 3 high-alumina cib yog ≤ 22%.
