· In the industrial production of titainum and titanium alloys, the most commonly used techniques are vacuum arc remelting (VAR) and cold hearth melting. Vacuum Arc Remelting VAR technology can refine the ingot structure in titanium alloy smelting and improve the purity of the product. The main developments of this technology in recent years are as follows: Fullyautomatic VAR re .
the bloomery process of early iron smelting; in this, the iron metal However, it was not before the late 18th century (1783) that two was also never liquid, but still formed a solid block or billet after brothers in Spain isolated and identified the new metal tungsten / sufficient forging. Chemically, tungsten ore is even easier to reduce wolfram. In the mid 19th century, the addition of ...
The history of tungsten dates back to the Middle Ages (mid 16th century) when tin miners in the Ore (Erz) Mountains of SaxonyBohemian Erzgebirge in Germany noticed that a certain mineral often accompanied its tin ore. The miners found that this mineral reduced the tin yield during the smelting process and increased slagging. would appear on the surface of the tin melt and a heavy slag ...
Tungsten is an important strategic metal, widely used in cemented carbide manufacturing, steel industry, and other economic fields. The amount of tungsten resource consumed in China each year accounts for more than 80% of the world's annual total consumption. The purpose of this study is to quantify the environmental impact of tungsten production in China through the method of LCA.

smelting process. In 1758, the same mineral was given the Swedish name "tung sten" or heavy stone (5). In 1781, two Swedish chemists produced tungstic acid from the ore and developed the first tungsten compounds. Two years later the Spanish d'Elhuyar brothers produced the first tungsten metal from the ore using charcoal to reduce the tungstic acid. The commercial market for tungsten was ...
History of Tungsten. Tungsten, like all the elements having a higher atomic number than iron (Z>26), cannot be formed by nuclear fusion processes in stars, as is the case for those elements with a lower atomic number, but originates only by neutron or proton absorption of already existing bigger capture processes with extremely high fluxes of neutrons and protons occur exclusively ...
