It is a more economical option to hot forge metals such as steel and then follow with heat treatment processes as metals such as steel can be strengthened through other processes (and not necessarily just cold working processes). If work hardening progresses, hard materials (such as steel and iron) will become more difficult to work with, andĢ. Iron, along with its alloys, are almost always hot forged for two main reasons:ġ. Hot forging aids in making the metal easier to shape as well as less likely to fracture. This allows for the flow stress and energy required to form the metal to lower, effectively increasing the rate of production (or strain rate). A process that was developed thousands of years ago, forging remains one of the most effective ways to produce metal parts for critical applications.Hot forging entails the heating of a workpiece to about 75% of its melting temperature. Many forging processes can now be automated with computers, streamlining the process and making for quick and precise parts for industries like aerospace and transportation. Steam powered forging hammers emerged during this time and are still used today along with hydraulic and electric powered units. James Hall Nasmyth (19 August 1808 – ) was a Scottish engineer, artist, and inventor and is credited for the development of the steam hammer receiving a patent in June 1842. The 19th century marked the turning point in the forging industry, leading the way for what is known as modern day forging techniques. The last known bloomery was used in Spain until the early 19th century. ![]() Waterwheels were used to power the bellows, allowing for bigger and hotter bloomery furnaces with an improvement in forging production. During the 13th century, water power was discovered as an effective way to power bloomeries. The forging and blacksmithing industry basically remained the same until the discovery of water power. These tuyeres were used to force air into the furnace using bellows to heat up the charcoal and increase furnace temperatures. These furnaces or pits were made of clay and stone and were designed to be heat-resistant, built with pipes referred to as tuyeres. Bloomery Furnaceĭuring the iron-age, bloomery furnaces rapidly replaced open charcoal fires as an effective way to forge. By this point, forging and metal production had spread throughout China and became a part of everyday life. ![]() During this period, Smith’s in the West forged wrought iron using charcoal fires and bellows to increase the heat of the fire and a hammer to bend, cut and shape the metal into arrowheads, knives, scrapers, tools and even artwork. as forging grew to be an essential part of human civilization, the term smith or blacksmith emerged. By 1,000 B.C., forging techniques and metals had spread throughout Europe and the rest of the old world. Soon after other metals were discovered, leading the way for stronger weapons and tools. Small wood burning fires and rocks were used to heat up the metal before pounding it into its desired shaped. In the early years of forging, settlements in Mesopotamia were known to use copper to create hand tools and weapons for survival. The art of forging and metalworking is found in human culture as early as 4,500 B.C. Forging, at a basic level, is the technique of shaping metal pieces using heat and force, often with a hammer, into parts for machines, tools and weapons.
