remelting

The statue was stolen on at least three occasions, the last time in 2003, obviously for the purpose of its subsequent remelting.

Continuing operations involve the remelting of aluminium scrap for re-use.

This remelting of the dendrites is called recalescence.

But the melting and remelting of recycled material eventually breaks down additives in it and otherwise makes it unusable.

The process of VIM can even begin electro-slag remelting, which can remelt electrodes.

Vacuum arc remelting is also used in production of titanium and other metals which are reactive or in which high purity is required.

There are different variants of the electro-slag remelting process where the remelting is done in vacuum or a protective atmosphere.

Vacuum Arc Remelting: This is done by striking an electrical arc between the raw material and a water-cooled copper strike plate.

Electro-slag remelting (ESR)

Vacuum arc remelting further removes lingering inclusions to provide superior steel cleanliness and further remove gases such as oxygen, nitrogen and hydrogen.

In the electro-slag remelting (ESR) process, steel scrap is first melted using the conventional process but is then remelted in a water-cooled form.

In the NMZ repeated crustal remelting and intrusion of charnoenderbitic magmas continued to 2.58 Ga, producing counterclockwise p-T paths.

The first, with a capacity of 150,000 tons per year, two 50-ton furnaces and two 20-ton ones for alloyed steels shaped into ingots, featured vacuum degasification and electro-slag remelting.

By April 2010, China Wind Systems expects to finish a new $6 million expansion at its facility that will allow it to produce steel through a process called electro-slag remelting(ESR).

Pilbara Granite-Greenstone Terrane c. 3.315 Ga monzogranites are typically highly fractionated, K rich, Al poor, and have trace element compositions consistent with remelting of an older tonalitic-trondhjemitic-granodioritic (TTG) crust.

Possibly the energy released by the decay of Fe contributed, together with the energy released by decay of the radionuclide Al, to the remelting and differentiation of asteroids after their formation 4.6 billion years ago.

The gun is made from high strength Electro Slag Remelting (ESR) steel with a chromium alloy lining and, like earlier British 120 mm guns, it is insulated by a thermal sleeve.

Although it is smaller than it once was, AK Steel remains the industry's sixth-largest integrated company, which means that it makes steel from iron ore, rather than remelting scrap steel as the newer mini-mills do.

The remelting and reworking of existing beads also suggests that the shape and style of glass beads held specific cultural values; various regions were able to imitate more favourable foreign styles, create unique forms or produce much larger beads than what was available through international trade, effectively expressing local distinctiveness.

Electroslag remelting (ESR), also known as electro-flux remelting, is a process of remelting and refining steel and other alloys for mission-critical applications in aircraft, thermal power stations, nuclear power plants, military technology, et al.
