Hluav taws xob rauv Magnesia-Carbon Bricks
Hluav taws xob rauv magnesia- carbon bricks yog refractory khoom tsim los ntawm fused magnesia thiab flaky graphite. Lawv yog tsim los ntawm resin-bonded pressing thiab kev kho cua sov. Txij li thaum lawv cov kev taw qhia txog kev lag luam hauv xyoo 1970, cov cib no tau siv dav hauv cov chaw kub thiab cov kab slag ntawm cov phab ntsa hluav taws xob, muab cov refractoriness siab, zoo heev thermal shock resistance, thiab superior slag corrosion kuj. Lawv cov ntsiab lus carbon yog li ntawm 10% mus rau 30%, uas yog siab dua li 10% -20% feem ntau pom nyob rau hauv converter magnesia-carbon bricks.
Hauv Tebchaws Meskas, Tebchaws Europe, thiab Nyij Pooj, cov cib no tau hloov pauv ntau yam fused magnesia-chrome, re-bonded magnesia-chrome, thiab ncaj-bonded magnesia-chrome cib ntawm qhov kub kub hauv phab ntsa hluav taws xob. Feem ntau, ntau yam magnesia - carbon bricks yog ua hauj lwm nyob rau hauv hluav taws xob furnaces, nrog rau cov uas sib txawv cov ntsiab lus carbon (los yog sib txawv C/MgO ratios), ntau hom carbon, sib txawv magnesia qib, thiab txawv binder systems.
Qhov tseem ceeb tshaj qhov sib txawv ntawm magnesia- carbon bricks rau hluav taws xob rauv thiab cov converters nyob rau hauv lawv taag carbon cov ntsiab lus: hluav taws xob rauv cib muaj 10%–30%, piv rau 10%–20% converter cib. Yog li ntawd, kev tsim hluav taws xob rauv magnesia- carbon bricks hu rau ntau dua ntawm flaky graphite. Lwm cov txheej txheem tsim khoom tseem tseem zoo ib yam li cov rau converter bricks.
Nyob rau hauv siab -hwj chim thiab ultra- siab- dej fais fab - cov hluav taws xob cua txias, cov cib no muaj txiaj ntsig tshwj xeeb hauv cov cheeb tsam uas raug hnav hnyav, xws li cov chaw kub thiab cov kab slag. Hauv cov ntawv thov no, lawv lub neej kev pabcuam tuaj yeem tshaj 300 heats. Magnesia- cov pa roj carbon cib tam sim no kuj tau siv nyob rau hauv qab ntawm lub cub hluav taws xob.
