Puddling (metallurgy) - Wikipedia

Puddling is a step in the manufacture of high-grade iron in a crucible or furnace. Known by the 1st century AD in the Han Dynasty of ancient China, [clarification needed] it was advanced in Great Britain during the Industrial Revolution.There molten pig iron in a reverberatory furnace was stirred with consumable rods [clarification needed] resulting in a less brittle, more purified steel.

Pig Iron Manufacturing Process

While the loss of iron in the slag with an electric furnace running on pig steel would probably be greater than in the case of pig iron, owing to the weaker reducing atmosphere of the pig-steel furnace, it should not be so excessive as to prohibit the use of such a process under favorable economic conditions.

Basic oxygen steelmaking - Wikipedia

Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel.Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.The process is known as basic because fluxes of burnt lime or ...

Open Hearth Furnace Usage Schematic Diagram ~ AxiBook

If the carbon content is too low, pig iron is added. This replenishes the carbon. Other alloying elements like Cr, Ni. Co, W, Mo, V etc. are added as needed. Ferromanganese may be added to the crucible after tapping. For acid lining furnace, the charge should be scrap iron and low-phosphorus pig iron. Limestone is required to keep the slag fluid.
