The first is referred to today as potting and stamping, but this was superseded by Henry Corts puddling process. Cort developed two significant iron manufacturing processes rolling in 1783 and puddling in 1784. Rolling replaced hammering for consolidating wrought iron and expelling some of the dross.

Rolling. In this, the bloom was passed through grooved rollers and flat bars were produced. The bars of wrought iron were of poor quality, called muck bars or puddle bars. To improve the quality of wrought iron, the bars were cut up, piled and tied together by wires, a process known as faggoting or piling.

Wrought iron a short history of the development of the

"puddling process". This new process allowed the production of wrought iron, in one plant, to increase from ten tons per week to two hundred tons per week. The handling of larger masses of iron with new and improved tools, methods, and equipment produced wrought iron of a much better quality than had been previously obtained.

Jan 16, 2018·Carbon plays a crucial role in iron and steel production. Carbon is often involved during the smelting process, and the higher temperature iron gets, the more carbon it will absorb. When iron takes on more and more carbon, it becomes harder and more brittle. Conversely, with less carbon, iron becomes more ductile and pliable.

Wrought iron

Wrought iron. In the 17th, 18th, and 19th centuries, wrought iron went by a wide variety of terms according to its form, origin, or quality. While the bloomery process produced wrought iron directly from ore, cast iron or pig iron were the starting materials used in the finery forge and puddling furnace.
