Puddling process | metallurgy | Britannica

Puddling process, Method of converting pig iron into wrought iron by subjecting it to heat and frequent stirring in a furnace in the presence of oxidizing substances (see oxidation-reduction). Invented by Henry Cort in 1784 (superseding the finery process), it was the first method that allowed wrought iron to be produced on a large scale.

Puddling (metallurgy) - Wikipedia

The process begins by preparing the puddling furnace. This involves bringing the furnace to a low temperature and then fettling it. Fettling is the process of painting the grate and walls around it with iron oxides, typically hematite; this acts as a protective coating keeping the melted metal from burning through the furnace.

Metallurgic Processes | Boundless Chemistry

The term “refining” is used in a narrower context. Henry Cort’s original puddling process only worked when the material was white cast iron, rather than the gray pig iron that was the usual material for finery forges. For the gray pig iron to be usable, a preliminary refining process was developed to remove the silicon.
