Khoom Description

Cov ntaub ntawv refractory yog cov ntaub ntawv tseem ceeb hauv kev tsim khoom thiab siv los tiv thaiv siab - cov khoom siv kub thiab cov phab ntsa sab hauv ntawm lub qhov cub. Magnesia spinel cib yog ib yam tshiab ntawm siab - cov khoom kub refractory nrog kev ua tau zoo heev thiab ntau yam kev siv. Magnesia spinel cib yog ib qho nyuaj siab - kub refractory khoom muaj li ntawm magnesium, txhuas thiab lwm yam khoom. Cov yam ntxwv tseem ceeb ntawm cov khoom no yog qhov kub thiab txias stability, muaj zog tiv taus acid thiab alkali corrosion, siab corrosion kuj, zoo thermal shock stability, thiab thermal conductivity. Vim nws qhov kev ua tau zoo heev, nws tau dhau los ua cov khoom siv dav siv siab -.

Magnesia spinel bricks muaj ntau yam ntawm daim ntawv thov scenarios thiab tuaj yeem ua rau ntau yam duab thiab specifications raws li kev lag luam sib txawv thiab cov khoom xav tau. Xws li puag ncig, duab plaub, tapered, nkhaus thiab lwm yam duab ntawm nkhaus cib, tiaj cib, koov cib, kiv cua-puab cib, thiab lwm yam.

Cov khoomQhov zoo

1. Muaj zog kub ua haujlwm

Magnesium spinel cib muaj qhov zoo heev - qhov kub thiab txias thiab tuaj yeem siv rau hauv qhov kub siab - ib puag ncig ntev yam tsis muaj teeb meem xws li ablation, thermal expansion thiab contraction. Qhov kub tsis kam ntawm cov khoom no tuaj yeem ncav cuag 1700℃thiab tuaj yeem tiv taus qhov kub thiab txias.

2. Zoo corrosion kuj

Magnesia spinel cib tuaj yeem tiv taus acid thiab alkali corrosion thiab muaj kev tiv thaiv corrosion zoo. Nws qhia tau hais tias zoo heev corrosion kuj nyob rau hauv kub, siab siab, muaj zog acid thiab alkali ib puag ncig. Cov cuab yeej no ua rau nws yog ib qho tseem ceeb ntawm cov khoom siv refractory dav siv hauv metallurgy, tshuaj lom neeg kev lag luam, hluav taws xob fais fab thiab lwm yam kev lag luam.

3. Zoo thermal shock stability

Magnesia spinel cib muaj qhov zoo thermal shock stability, tuaj yeem tiv taus qhov kub thiab txias kev ntxhov siab, thiab tsis tuaj yeem tawg thiab tawg. Qhov kev ruaj ntseg no tso cai rau nws ua tau zoo dua hauv kev mining, cement, petrochemical thiab lwm yam lag luam.

4. Zoo thermal conductivity

Magnesium spinel bricks muaj cov thermal conductivity thiab thermal conductivity, uas tuaj yeem hloov cov hluav taws xob sai thiab pab txhim kho cov khoom siv. Nyob rau tib lub sijhawm, cov khoom siv nws tus kheej tsis yooj yim rau khaws cov cua sov, yog li tsis txhob siv hluav taws xob pov tseg.

5. Kev ntseeg tau zoo

Magnesium spinel bricks muaj cov khoom tsim nyog, kev sib txuas zoo, kev tsim khoom zoo, thiab kev ua haujlwm siab thiab kev ntseeg siab. Hauv kev siv tiag tiag, nws tuaj yeem tswj hwm kev ua tau zoo thiab siv cov teebmeem rau lub sijhawm ntev, dhau los ua qhov kev lees paub zoo hauv kev tsim khoom.
