Cov cib magnesite alumina carbon yog ib hom cib refractory uas ua los ntawm cov qib tshwj xeeb alumina bauxite siab lossis emery, magnesia thiab flaky graphite ua cov khoom tseem ceeb. magnesia alumina carbon firebrick muaj cov yam ntxwv ntawm kev tiv thaiv corrosion siab, refractoriness siab thiab tus cwj pwm zoo hauv qab qhov kub siab, thiab lwm yam. Magnesia alumina carbon refractory cib yog dav siv rau hauv cov hlau molten ladle liner. Thiab tseem magnesia alumina carbon firebrick yog siv rau hauv lub dab dej molten thiab ladle hauv qab ntawm kev sib txuas ntxiv casting loj tundish thiab sab nraud lub cub tawg refining pob yog nce ntxiv.
Cov Khoom ntawm Magnesia Alumina Carbon Bricks
- Qhov porosity qis dua thiab kev ua kom sov tsawg,
- Kev tiv thaiv thermal zoo,
- Muaj zog heev, zoo tiv taus corrosion,
- Kev tiv thaiv kev yaig zoo, kev tiv thaiv slag siab,
- Zoo heev tiv thaiv kev oxidation thiab tiv thaiv kev stripping.
Cov txiaj ntsig ntawm Magnesia Alumina Carbon Bricks
Cov cib hluav taws kub Magnesia alumina muaj cov khoom tiv thaiv kev yaig, tiv thaiv kev tawm tsam, tiv thaiv kev laus thiab tsis nplaum cov khoom seem thiab lwm yam. Cov cib hluav taws kub magnesium alumina carbon tau siv dav hauv ladle hauv kev sib txuas ntxiv casting thiab hauv qee qhov kev txo qis qhov tsis sib xws ntawm lub neej ntawm ladle casting.
Cov Txheej Txheem Tsim Khoom ntawm Magnesia Alumina Carbon Bricks
Magnesia alumina carbon block yog cov khoom siv refractory nrog cov bauxite qib tshwj xeeb
magnesite lossis corundum thiab flake graphite, uas yog tus yam ntxwv hauv qhov kub siab nrog cov pa roj carbon siab nrog kev tiv thaiv corrosion siab thiab tiv thaiv stripping zoo, kuj muaj
lub cua sov tsim los ntawm kev siv spinel thiab pom cov kab seem ntawm qhov piv txwv nthuav dav siab
qhov zoo, tau dhau los ua qhov kev txhim kho tshiab ntawm cov cib zoo hauv pem teb.

Daim Ntawv Thov ntawm Magnesia Alumina Carbon Bricks
Cov cib hluav taws kub magnesium alumina carbon siv dav hauv ladle hauv kev casting tas mus li thiab hauv qee qhov kev txo qis qhov tsis sib xws ntawm lub neej ntawm ladle casting tas mus li. Tsis tas li ntawd, magnesium alumina carbon firebrick tuaj yeem siv rau hauv cov chaw hauv qab no:
- 1. Cov khoom hloov pauv, EAF, cov chaw ua kom sov,
- 2. Kab Slag thiab kab hlau rau ladle,
- 3. Hluav taws xob arc cub tawg ua haujlwm txheej,
- 4. Lub tshuab cua sov ua haujlwm txheej txheem,
- 5. Lub cub hluav taws xob zoo heev, lub ladle hauv thiab kev ua kom zoo sab nraum lub cub tawg.
