Khoom Description

Refractory magnesia carbon cib yog tsim los ntawm siab -purity magnesium oxide thiab siab- zoo graphite hmoov los ntawm cov txheej txheem ntau lawm xws li crushing, mixing, nias, ci, thiab siab -kub graphitization thiab purification. Cov ntsiab lus magnesium oxide nyob nruab nrab ntawm 85% thiab 90%, thiab cov ntsiab lus graphite yog nyob nruab nrab ntawm 10% thiab 15%. Txij li thaum magnesium oxide yog ib qho oxide nrog lub siab melting point, nws muaj peev xwm tiv taus corrosion ntawm siab - kub molten hlau thiab siab - kub gas. Graphite muaj qhov zoo thermal conductivity thiab thermal shock stability, thiab tuaj yeem tiv taus thermal shock loads thiab cyclic thermal shock loads ntawm qhov kub thiab txias.

Magnesia carbon bricks muaj cov khoom zoo. Tom qab ntau qhov kev sim ntawm lub Hoobkas, qhov kub siab tshaj plaws - tiv taus kub tuaj yeem ncav cuag 2500 degree, thiab nws qhov hluav taws kub yog 3 mus rau 5 npaug ntawm cov khoom siv graphite zoo tib yam.

Cov khoomQhov zoo

1. Kev tiv thaiv hluav taws zoo

Magnesia carbon bricks muaj qhov hluav taws kub zoo thiab tuaj yeem tswj tau cov khoom siv tshuaj lom neeg ruaj khov hauv qhov kub thiab txias. Nws qhov kub thiab txias tuaj yeem ncav cuag tshaj 2000℃thiab tsim nyog siv rau hauv ntau yam khoom siv thiab cov txheej txheem ntawm qhov kub thiab txias.

2. Zoo thermal conductivity

Magnesia carbon bricks muaj thermal conductivity zoo thiab tuaj yeem ua cua sov sai thiab tiv thaiv kev ntxhov siab thermal. Cov cuab yeej no yog ib qho ntawm cov khoom tseem ceeb ntawm qhov kub thiab txias.

3. Zoo thermal shock stability

Cov graphite tivthaiv ntawm magnesia carbon bricks tuaj yeem ua rau nws cov thermal shock stability. Nws tsis tuaj yeem ua rau tawg tawg nyob rau hauv thermal shock loads ntawm qhov kub thiab txias thiab tuaj yeem tiv taus cyclic thermal shock loads zoo.

4. Zoo corrosion kuj

Magnesia carbon bricks muaj kev tiv thaiv zoo rau kev yaig los ntawm cov hlau molten thiab siab - kub gases. Magnesia carbon bricks tuaj yeem suav hais tias yog cov cib refractory hauv cov cua sov hlau thiab siab - qhov kub thiab txias, uas muaj txiaj ntsig zoo dua.

Cov khoomDaim ntawv thov

1. Hlau rauv

Hlau furnaces yog ib qho ntawm cov kev siv tseem ceeb ntawm magnesia carbon cib. Nyob rau hauv cov txheej txheem ntawm cov hlau refining thiab smelting, lub cub tawg lub cev yuav tsum tau tiv taus kub thiab molten hlau corrosion mus ntev. Kev siv cov magnesia carbon cib tuaj yeem ua kom ntev lub neej ntawm lub cub tawg.

2. Hluav taws xob arc rauv

Hluav taws xob arc rauv yog lub siab - cov khoom siv kub siv rau kev sib tsoo ntau yam hlau, lithium roj teeb thiab lwm yam kev lag luam. Magnesia- cov pa roj carbon cib yog qhov tseem ceeb ntawm cov hluav taws xob arc rauv. Vim muaj ntau hom thiab ntau, lawv tuaj yeem kho raws li kev siv sib txawv.

3. Silicon rauv

Lub cub hluav taws xob silicon yog qhov tshwj xeeb siab - cov khoom siv kub uas nws qhov kev ua haujlwm kub tuaj yeem ncav cuag tshaj 1400℃. Magnesia carbon bricks ua lub luag haujlwm tseem ceeb hauv silicon furnaces thiab tuaj yeem tiv thaiv kev nkag mus ntawm silicon furnace thiab thermal stress.

Nyob rau hauv luv luv, magnesia- carbon bricks yog ib qho zoo tagnrho siab - cov khoom kub thiab yog dav siv nyob rau hauv hlau furnaces, hluav taws xob arc rauv, silicon furnaces, boilers, hnyav roj catalytic hydrogenation thiab lwm yam teb. Nws muaj qhov hluav taws kub zoo, thermal conductivity thiab thermal shock stability, thiab tuaj yeem ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias ib puag ncig.
