 The process of puddling in a reverberatory furnace

The puddling or the refining of metal was a process that consisted of the heating of a reverberatory oven and at high temperatures the ingots of steel melted to eliminate part of its carbon component and the slag that had been introduced during the casting process. In these puddling furnaces the metal did not come into direct contact with the coke carbon, instead it received the heat reflected on the walls of the furnace in order to avoid the addition of impurities. Once the ingots were completely melted the puddling or the arm movement began, stirring the liquid with a spit so that, when the slag was mixed with the metal, it was eliminated through oxidisation.

 

The wrought iron or soft iron

The ingots of melted steel obtained from the blast furnace were transformed into soft steel, also called wrought iron, reducing its content of carbon and eliminating at the same time by oxidisation a great part of its impurities such as sulphur, phosphorous, manganese and silicon. This process, which was mainly done through puddling in the reverberatory furnaces, was completed by submitting the "billets" of steel obtained to the percussion of the steam hammer, eliminating in this way the slag that had been mixed with the steel during the initial fusion.
