ANKERSYN — A NEW GENERATION OF PERICLASE-CARBON
REFRACTORIES USING A CARBONACEOUS BINDER

Using a newly developed binding system, a new generation of periclase-carbon refractories bonded with a car
bonaceous binder with a low emission of hazardous volatiles is proposed. The new binding system gives a
high coking yield in carbon, which provides favorable conditions for very strong carbon-based cross-linking.
Another advantage of the new system is high resistance to oxidation and thermal stress. The newly developed
products have been successfully marketed under a trade mark ANKERSYN. ANKERSYN components were
tested, with good results, on a 270-ton oxygen converter (BOF) at the Sollac Atlantique Co. (France).
ANKERSYN makes it possible to manufacture products with superior performance characteristics, in confor-
mance with the ever-demanding requirements placed on the production technology and environmental protection.
Currently, magnesia-based materials bound with a syn-
thetic resin and pitch have found use in the refractory lining
of oxygen converters, electric arc furnaces (EAF), and steel
ladles . Coal-tar pitch and phenol resins, because of their
high content of residual carbon, are best suited for periclase-
carbon components (Table 1). In Europe, pitch-bonded peri
clase-carbon components have gained greater acceptance be-
cause they were easier, than components bonded with syn-
thetic resins, to adapt to the operating conditions of oxygen
converters and steel ladles of the European industry.
Major objectives in the development of refractories are
targeted at improving the performance characteristics as well
as at cost reduction and proper environmental management.
Over the past 15 years, efforts to minimize environmental
impact from the development and application of refractory
materials have increased significantly. Since all organic
binders during their preparation and uses in the high-temper
