Khoom Description
Raws li kev faib tawm ntawm cov khoom siv hluav taws xob refractory cib, cov cib refractory tau muab faib ua acidic refractory cib, alkaline refractory cib, nruab nrab refractory cib.
Khoom Specifications
- Silica cib, zirconia quartz cib yog tshuaj lom neeg ntawm acidic refractory cib,
- magnesium cib, magnesium chromium cib, magnesium calcium cib yog ntaus nqi rau alkaline refractory cib,
- siab alumina cib, av nplaum cib, corundum cib yog ntaus nqi rau ib nrab nruab nrab refractory cib.
Feem ntau ntawm cov kiln nrog nruab nrab refractory cib tuaj yeem ua tau, xws li siab aluminium cib, av nplaum cib, mullite cib. Cement kilns thiab txiv qaub kilns siv ntau alkaline refractory cib.
Acid refractory bricks yog ib qho yooj yim rau hnov mob nrog cov tshuaj alkaline ntawm qhov kub thiab txias thiab raug eroded. Alkaline refractory cib yog qhov cuam tshuam rau kev yaig los ntawm cov tshuaj acidic ntawm qhov kub thiab txias. Qhov nruab nrab refractory cib vim Al2O3 thiab lwm yam amphoteric oxides tom qab kub kub kub los tsim cov tshuaj inert variant, tsis yooj yim mus ua si nrog acidic tshuaj, tab sis kuj tsis yooj yim mus ua si nrog alkaline tshuaj, thiab yog li zoo dua tiv thaiv acid thiab alkali yaig kev ua tau zoo. .
Nyob rau hauv kev xaiv ntawm refractory bricks, yuav tsum tau them sai sai mus rau lub redox zog ntawm lub cub tawg. Yog hais tias lub cub tawg muaj CO ntau dua, ntawm qhov kub siab CO yog ib qho yooj yim heev rau refractory cib nrog qee cov hlau oxides (xws li FeO) lub luag hauj lwm, cov hlau raug txo. Ua kom lub refractory cib qhov sib txawv ntawm qhov tshwm sim ntawm carbon deposition, tseem yuav ua rau refractory cib zog poob thiab tawg. Yog li ntawd, hom refractory cib no yuav tsum muaj cov ntsiab lus hlau oxide ntawm 3 feem pua lossis tsawg dua (hu ua anti-carburization cib).
