ESR reduces other types of inclusions as well, and is seen as an alternative to the vacuum arc remelting (VAR) method that is prevalent in US industries. An example of the use of the electro-slag refined (ESR) steel technique is the L30 tank gun. CrNi60WTi is a stainless steel which is best formed by either electro-slag remelting or vacuum arc ...
Vacuum arc remelting (VAR) is a secondary melting process for production of metal ingots with elevated chemical and mechanical homogeneity for highly demanding applications. [1] The VAR process has revolutionized the specialty traditional metallurgical techniques industry, and has made possible tightly controlled materials used in biomedical ...
The magnetic flux threading the ring, represented by five field lines, is reduced by the same ratio as the area of the ring. The variation of the magnetic flux induces a current (red arrows) in the ring by Faraday's law of induction, which in turn creates a new magnetic field circling the wire (green arrows) by Ampere's circuital law. The new ...
Rosin used as flux for soldering A flux pen used for electronics rework Multicore solder containing flux Wire freshly coated with solder, held above molten rosin flux. In metallurgy, a flux is a chemical reducing agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time.
Refining of a 9.5%CrMoWVNbN steel in an argon, oxygen decarburisation (AOD) vessel. Argonoxygen decarburization (AOD) is a process primarily used in stainless steel making and other high grade alloys with oxidizable elements such as chromium and aluminium.
Additional flux is added until the molten slag, reaching the tip of the electrode, extinguishes the arc. The wire is then continuously fed through a consumable guide tube (can oscillate if desired) into the surfaces of the metal workpieces and the filler metal are then melted using the electrical resistance of the molten slag to cause coalescence .
According to the International Monetary Fund, Sri Lanka's GDP in terms of purchasing power parity is second only to the Maldives in the South Asian region in terms of per capita income. As of 2010 [update] , the service sector makes up 60% of GDP, the industrial sector 28%, and the agriculture sector 12%. [ 1 ]
The Sri Lankan Rupee (Sinhala: රුපියල්, Tamil: ரூபாய்; symbol: රු (plural) in English, රු in Sinhala, ௹ in Tamil; ISO code: LKR) is the currency of Sri Lanka. It is subdivided into 100 cents ( Sinhala : සත , Tamil : சதம் ), but cents are rarely seen in circulation due to their low value.
