What is puddling in the Industrial Revolution?
Puddling was one step in one of the most important processes of making the first appreciable volumes of high-grade bar iron (malleable wrought iron) during the Industrial Revolution. In the original puddling technique, molten iron in a reverberatory furnace was stirred with rods, which were consumed in the process.
What is the puddling process?
(Show more) 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 ).
How did puddling improve the quality of steel?
The puddling process was already known in ancient China during the Han Dynasty by the 1st century AD. The improvement of steel making processes improved the overall quality of steel by repeated forging, folding, and stacking of wrought iron from pig iron to make swords.
What is a puddling furnace?
The puddling furnace is a metalmaking technology to create wrought iron from the pig iron produced in a blast furnace. Pig iron contains high amounts of carbon and other impurities, making it brittle. The puddling furnace burns off these impurities to produce a malleable low-carbon steel or wrought iron.
