Steelmaking Refractories( EAF)
RAMMING MASS FOR EAF HEARTH
It is made from synthesized high quality MgO-CaO-Fe₂O₃as main material with proper grain size distribution which makes it has good sintering and good corrosion resistance.It is convenient for construction and has strong integration,it can be initially constructed or used in hot repair in high power EAF,extra-high power EAF bottom,side wall and slope.
