The forge will be the heart of the blacksmith’s shop. It’s from the forge that the blacksmith heats metal until it reaches a temperature and becomes malleable enough for him to utilize his other equipment to shape it.
The traditional blacksmith’s forge has changed and become more sophisticated over time, though the fundamental principles remain unchanged. The most typical forge could be the one fired by coal, charcoal or coke. The forge is often a specially designed hearth the location where the temperature can be controlled so your metal is heated on the temperature the blacksmith wants, determined by what he plans to do – shaping, annealing or drawing. The there main areas of the forge are:
· The hearth where the burning coke (and other fuel) is contained as well as over which the metal is placed and heated.
· The Tuyere the industry pipe leading into the hearth by which air is forced. The strength of the hearth and also the heat it creates will depend on how much air being fed for it over the Tuyere tube.
· The bellows include the mechanism by which air needs over the Tuyere tube into the hearth. While earlier bellows were pumps operated by muscles power, modern forges have high power fans or bowers to make air in the Tuyere
The blacksmith adjusts a combination of air and fuel from the hearth the produce the exact temperature had to heat the metal. A regular blacksmith’s forge may flat bottomed hearth together with the Tuyere entering it from below. The core from the fire is a mass of burning coke during the hearth. With this in mind burning coke will be a wall of hot, however, not burning coal. This wall of coal serves two purposes. It provided insulation and possesses and focuses heat of the fire to some limited area, allowing the blacksmith to heat the metal in a precise manner. The hot coal also becomes transformed in coke which can then be harnessed for fuel for your hearth.
The outer wall from the fire consist of a layer of raw coal, which is often kept damp in an attempt to control heat in the inner layer of hot coal to ensure is may slowly "cook" into coke.
The size of the fire and the heat it generates could be changed by either adding or removing fuel from it at the same time and adjusting air flow. By changing the design in the outer layers of coal, the form from the fire may also be modified to suit the design from the metal piece being heated.
Many modern blacksmiths use gas forges. These are generally fueled by either gas main or propane. The gas is fed to the hearth, that is lined by ceramic refractory materials, and blended with air and ignited. Pressure to succeed from which the gas has been fed into the hearth could be adjusted to vary the temperature. While gas forges are simpler to use and require less cleaning and maintenance, the downside is that, unlike a coal fired forge, the contour of the fire is proscribed and will not be changed to accommodate the design and sized the metal being heated.
