Furnace design is a complex process, and the design can be optimized based on multiple factors. Furnaces in foundries can be any size, ranging from mere ounces to hundreds of tons, and they are designed according to the type of metals that are to be melted. Also, furnaces are bound by the fuel available that will produce the desired temperature. For low temperature melting point alloys, such as zinc or tin, melting furnaces may reach around 600 Kelvin. On the high end, from steel, nickel based alloys, tungsten, all the way to other elements with higher melting points, furnaces can reach to over 3600 Kelvin. The fuel used to reach these high temperatures can be electricity, natural gas or propane, charcoal, coke, fuel oil, or wood.

The majority of foundries specialize in particular metals and have furnaces dedicated to these metals. For example, an iron foundry (for cast iron) may use a cupola, similar to a small blast furnace. While a steel, bronze, or brass foundry will normally use an electrical induction furnace. However, in some cases, they may use a gas heated crucible furnace. Most aluminum foundries use either an electric resistance or gas heated crucible furnace. Cast iron usually refers to grey cast iron, but can mean any of a group of iron-based alloys containing more than 2% carbon (alloys with less carbon are carbon steel by definition). ...

Pouring In a foundry, molten metal is poured into molds. Such molds may be made of sand, metal for permanent molding, ceramic, or refractory materials. The pouring can be accomplished with gravity, or it may be assisted with a vacuum or pressurized gas. One half of a bronze mould for casting a socketed spear head dated to the period 1400-1000 BC.

Casting When the molten metal changes states from liquid to solid, it is said to be cast into a shape. This article is about the manufacturing process. ...
Advantages The finished product of a foundry can be more versatile than the product of a rolling or machining process. Also, the process of casting molten metal, as is occurs in a foundry, can be far more automated than the labor-intensive machining method. profile rolling (to manufacture a cone) Rolling is a fabricating process in which the metal, plastic, paper, glass, etc. ...
