The ingot is a mass of metal that has been cast into a size and shape known otherwise as a bar, plate or sheet. The use of ingot molds is designed to provide a convenient mode of storage, transportation and processing to finally form the semi-finished or finished product. The mold is the container into which metal will be cast. Typical metals cast into ingots for its further processing include gold, silver and steel.
Steel ingots will range in size from small rectangular blocks that weigh no more than a few pounds, to huge, tapered and octagonal constructions that can way as much as five hundred tons. The tin ingot will be the starting material for numerous products. Tin may be alloyed to other metals, converted to other physical forms, converted to chemical compounds, or applied to other metal surfaces.
To cater for one of the so-called exotic materials otherwise known as titanium, a purified titanium sponge needs to be transformed into a shape that can accommodate a variety of structural purposes. This conversion needs to go through several steps. The consolidation into and transference to a titanium ingot will be performed in a vacuum or what is known as, argon environment.
This is made possible by performing what is known as the consumable electrode arc melting process. All sponge, alloying elements, and even recycled materials, will be mechanically compacted before being welded into a long, cylindrical electrode. The electrode gets melted vertically into a water cooled copper vessel by way of passing an electric current through it. In order to achieve uniformity, the main ingot still needs to be re-melted in similar manner to the first and original melting process.
Such ingots can weigh as much as ten tons and are over a thousand millimeters in diameter.
