the puddling process
Henry Cort (c. 1740 – 23 May 1800) was an English ironmaster.During the Industrial Revolution in England, Cort began refining iron from pig iron to wrought iron (or bar iron) using innovative production systems. In 1783-1784 he patented an improved version of the puddling process for refining cast iron although its commercial viability was only accomplished by innovations introduced by the ...
Plaster Casting. Plaster casting is a casting process with similarities to sand casting. Instead of using sand in the process, a mixture of water, gypsum and strengthening compounds are used. Advantages. Plaster casting is capable of delivering a closer dimensional tolerance than sand casting is able to. It delivers a smooth, as-cast finish.
Puddling used the plentiful coke, instead of the expensive charcoal. The combination of puddling and grooved rollers was a process that could be mechanized, for example, by the steam engine, which had just been introduced. The result was that production of wrought iron was increasingly carried out in a group of coordinated processes in a single ...
Puddling process: 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
Puddling definition is - the process of converting pig iron into wrought iron or rarely steel by subjecting it to heat and frequent stirring in a furnace in the presence of oxidizing substances.
Puddling was the first true industrial process to make steel from pig iron. A primitive version of the process was known in China already in the 3rd century. The pig iron tapped off the blast furnace was puddled with iron bars, bringing it into it contact with oxygen in the air and burning off any ...
Puddling was an Industrial Revolution means of making iron and steel.In the original puddling technique, molten iron in a reverberatory furnace was stirred with rods, which were consumed in the process. Later, it was also used to produce a good-quality steel with the correct amount of carbon; this was a highly skilled art, but both high-carbon and low-carbon steels were successfully produced ...
Henry Cort invented the puddling process. This process transformed the production of wrought iron by making it more large-scale and less costly, thus impacting the Industrial Revolution. Cort was ...
In refining iron, and making steel, the puddling process removed impirities from crude pig iron. Until the creation of the Bessemer process, it was the best method to do this.

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 hematite.
The process was perfected in 1784 by H. Cort, who played a major role in the widespread adoption of the process. In essence, the process requires that pigs of iron be loaded onto the hearth of a puddling furnace. The molten metal and slag found in the furnace are stirred (puddled) with metallic rods in order to increase the contact surface.
Henry Cort, 1740–1800, English inventor. He revolutionized the British iron industry with his use of grooved rollers to finish iron, replacing the process of hammering, and through his invention of the puddling process.
