Acidic Regractory cov ntaub ntawv feem ntau yog xa mus rau cov ntaub ntawv refractory nrog Sio2 cov ntsiab lus ntau dua 93%. Lawv tus cwj pwm tseem ceeb yog tias lawv tuaj yeem tawm tsam txoj kev yaig ntawm acidic slag ntawm qhov kub thiab txias, tab sis ib txwm yuav kom muaj kev sib cav sib ceg. Cov khoom siv acidic refractory yog silica cib thiab av nplaum cib. Silica bricks yog cov khoom lag luam silighous yog cov khoom lag luam silicous muaj ntau dua 93% silicon oxide, thiab yog ua los ntawm cov khoom nyoos xws li Silica Cib. Lawv muaj zog tiv taus cov kua qaub sawb yaig, siab thauj softening kub, thiab tsis txhob txiav lossis txawm me ntsis nthuav tawm tom qab rov ua dua; Tab sis nws yog qhov raug cuam tshuam rau kev yaig los ntawm Alkaline Slag thiab muaj kev tsis zoo thermal kev co ua hauj. Silicon Cib feem ntau yog siv nyob rau hauv cov khoom siv thermal xws li Coke Ncu, iav melting rauv, thiab acid steelmakaking rhuab. Av nplaum cib feem ntau yog ua los ntawm cov av nplaum refract thiab muaj 30% rau 46% alumina. Lawv tsis muaj zog acidic refractory nrog kev co thermal kev co ua kom ua hauj lwm thiab corrosion tsis kam rau acidic slag, thiab yog siv dav. 2. Cov ntaub ntawv refractory feem ntau yog hais txog cov khoom siv refactory tsuas yog suav cov khoom siv hloov oxide lossis magnesium roj calcium thiab calcium. Cov khoom siv refractory muaj kev ua kom siab dua thiab muaj zog tiv taus alkaline slag. Piv txwv li, magnesia magnesia, Magnesia chrome cib, chrome polumina cib, piv txwv li cov tshuab hluav taws xob tsis yog siv rau hauv cov tshuab hluav taws xob alkaline, thiab cov hlau nplaum uas tsis yog, thiab cov khoom noj kom xis. 3. Aluminium cov ntaub ntawv relicate rorgact screen hais txog cov khoom siv refactory tsuas yog tsim ntawm sio 2- AL2O3. Raws li lawv cov ntsiab lus Al2o3, lawv tuaj yeem faib ua peb pawg: semi li} 3 30-48%), thiab high alumina (al2o3 ntau dua 48%). 4. Melting thiab casting cov ntaub ntawv Refractory hais txog cov khoom siv hluav taws xob nrog cov duab me me uas tau muab melting los sib tov ntawm qhov kub thiab txias siv. 5. Nruab nruab nrab cov ntaub ntawv xa mus rau cov khoom siv refactory uas tsis yooj yim ua rau cov khoom siv acidic lossis alkaline slag lossis alkaline cov khoom siv thiab cov khoom siv chromium refractory. Qee cov neeg cais cov nyiaj siab siab ntau alumina refractory raws li xws li. 6. Cov khoom lag luam refractory tshwj xeeb yog cov khoom siv tshiab ntawm cov khoom siv tsis zoo nkauj tsim los ntawm cov khoom siv teev ua ke thiab cov khoom siv dav dav. 7. Amorphous Refractory cov ntaub ntawv yog cov sib xyaw ua ke muaj cov hmoov nplej regractory, binders, lossis lwm yam ntxiv rau cov dej sib ntxiv lossis sib xyaw ua ntej siv. Cov khoom siv tsis tau hloov kho yog hom khoom tshiab ntawm cov khoom siv rov qab uas tsis yog calcenory, thiab nws cov refactoriness tsis tsawg tshaj 1580 degree.
