Magnesite Ramming Mass EAF Bottom Ramming Mass 60-85% MgO easy construction
Magnesite Ramming Mass
Refractory dry ramming mass for EAF bottom are made from high quality magnesite and Fe2O3-CaO magnesite, and show the features of excellent resistance against steel penetration, superior erosion resistance, easily-sintering, high bulk density and easy installation. Dry rammmg mixes for EAF bottom is ideal choice for HP/UHP EAF bottom.
CH Refractory Electric furnace bottom ramming material uses the synthesis process into a ball and high temperature calcination, Israel magnesium stone as the main crystal phase, with a transitional phase to dissolve C2F for ceramic glue combination, at the same time, the completion of sintering, through the main crystal phase combined with the boundary between the solid solution reaction diffusion and part of each other, forming high temperature stability of microstructure (whole sintering layer),To ensure that the use process is safe and reliable, convenient construction, is not limited by the size of the furnace, can be applied to all kinds of specifications of electric furnace bottom.

Advantages of Magnesite Ramming Mass:
Dry rammmg mixes for EAF bottom is dry material, so it is easy to
be constructed on work site, and ready to be used after
construction done. Without baking, dry rammmg mixes for EAF bottom
largely improves the efficiency and extends the service life as
well.
These Ramming Mass have the advantages of easy installation, high bulk density, easy sintering, strong resistance to molten steel penetration, and strong resistance to erosion / corrosion. This product is ideal choice for converter, EAF, ladle.
Packages of ramming mass
The package is designed to protect ramming mass from humidity.
However, as with all hydraulic binders, it is recommended that
ramming mass not be placed outdoors or in direct contact with the ground. When
correctly stored in dry conditions, the properties of ramming mass
will remain within specification limit for at least 6 months. In
most cases, its properties will be retained for over a year.
