What are the advantages of using Magnesia ramming mass as the furnace roof material?
a), Magnesia ramming mass with simple composition which can be easily exchanged, and costs only 1/4 of the general castables.
b), Magnesia ramming mass with excellent resistance to high temperature, the ancillary water cooling device of electric furnace was cancelled, which reducing the energy consumption and ensuring the production safety.
c), Magnesia ramming mass composition is unity thus it can't be damaged due to the difference of thermal expansion which can ensure the service life.
d), After using magnesia ramming mass, the top cover of the electric furnace doesn't need to be filled as a whole, and its divided into block structure, which is more convenient and safe for handing.
