Process For Purifying Iron By Puddling

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. Sometimes finely pounded cinder was used instead of …

Puddling: A New Look at an Old Process

The Puddling Process 1.1. Historical Aspects Henry Cort, in 1784, perfected the process of decarburiz-ing cast iron in a reverberatory furnace fired with coke, the oxidizing agent being the furnace atmosphere.1,2) The process required constant stirring and so came to be known as puddling. After about 1795, British iron masters quickly adopted Cort’s process, and by 1815 …

Refining (metallurgy) - Wikipedia

In metallurgy, refining consists of purifying an impure metal. ... Henry Cort's original puddling process only worked where the raw material was white cast iron, rather than the grey pig iron that was the usual raw material for finery forges. To use grey pig iron, a preliminary refining process was necessary to remove silicon. The pig iron was melted in a running out furnace …

What is Puddling?

Puddling is a metallurgical process which was used during the Industrial Revolution as a means of making iron and steel. It is used by subjecting pig iron or any other impure metal to intense heat and frequent stirring inside a furnace, and in the presence of oxidizing substances. This process frees the metal from some of its impurities, such as

Steelmaking and Refining | Introduction to Chemistry

Henry Cort’s original puddling process only worked when the raw material was white cast iron, rather than the gray pig iron that was the usual raw material for finery forges. For the gray pig iron to be usable, a preliminary refining process was developed to remove the silicon. The pig iron was melted in a running-out furnace and then run out into a trough. This process …

The Six Main Steps of Iron Ore Processing | Multotec Canada

Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher’s CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency. Fine particles make the crusher less efficient and increase the power …
