Wrought Iron. Manufacture Of Wrought Iron

Wrought is manufactured from forge pig by the following processes.. Refining, or exposure when fused to a strong current of air which removes part of the carbon. Puddling, by which the molten metal is still further exposed to a blast of air and oxidising substances in a reverberatory furnace. The remainder of the carbon is thus removed, and clotty lumps or "puddle halls " of pure appear.

Iron processing - Iron making | Britannica

This is any process in which is extracted from ore at a temperature below the melting points of the materials involved. Gangue remains in the spongelike product, known as direct-reduced , or DRI, and must be removed in a subsequent steelmaking process. Only high-grade ores and pellets made from superconcentrates 66 percent are therefore really suitable for DR making.
