Selection Of Magnesia Carbon Brick Raw Materials
Magnesia carbon brick is developed in Japan as an electric furnace application, the first application in the converter experiment began in 1970, after 6 years of formal promotion and use, 1977 Kawasaki Steel Company in the converter furnace bottom and tuyere for the first time the use of resin-bonded magnesia carbon brick, creating a precedent for the use of graphite composite refractories in the converter. Asphalt bonded magnesia carbon brick from Western Europe, the usual magnesia carbon brick is a combination of magnesia and flake graphite as a bonding agent added thermosetting resin, adding or without anti-oxidant non-fired brick.
In recent decades, due to increasingly harsh smelting conditions and constantly changing steel smelting production technology, higher requirements have been put forward for magnesia carbon refractories, mainly focused on improving the process, improving the quality and use effect, and has achieved good results.
