Abstract

The Walloon method of refining pig (cast) iron is one of the first extensions of the blast furnace process, which appears between the 14th and 16th centuries in northern Europe. This study investigates the production capacity of Walloon refining and in particular its handling of high-phosphorus pig iron through a series of experiments. A Walloon hearth was built to refine high-phosphorus pig iron, using data on the refining process found in archaeological sources and historical documents fro m the 18th century onwards. The chemical composition and the structure of the metals and slag produced during refining have been determined. A similar yield to those mentioned in historical sources has been obtained. These experiments suggest specific techniques enabling high-phosphorus pig iron to be refined efficiently. Finally,the results point out the importance of the metal-slag reaction phase in obtaining a carbon-free and phosphorus-free material.
