Alumina Bricks |
Alumina-Magnesia-Carbon Brick
|
Made
of 96-98% MgO electric fused magnesite, super quality bauxite
and 194-196 large crystal natural flake graphite, with antioxidation
addictives and special resin bond. With superior resistance
to slag, corrossion, oxidation, thermal shock and constructional
spalling etc.Providing customer oriented and cost effective
designing, manucfacuring, exporting of the alumina magnesia
carbon bricks .This type of new products used as lining
material in the various ladles, LFV refining furnace and
LF ladles have experienced an average lifetime from 70 heats
to 130 heats in the past 3 years.
