Rendering of electro-slag remelting apparatus and cross-sections. 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 and others.
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. With this process, a more even microstructure can be achieved which gives completely different properties than a material produced with the conventional method.
Quench polish quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is sometimes known by the brand name of Tufftride, Tenifer or Melonite. [1]
High purity iron is also produced in dry process. VOD (vacuum oxygen decarburization), and ESR (electro-slag remelting) are known as dry process. VOD is a process of melting pure iron in a vacuum and degassing. ESR (electro-slag remelting) method is a process of dripping the molten metal refining pure iron as an electrode.
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 ...
Valero Energy Corporation (NYSE:VLO) reported a fourth-quarter sales decline of 13.2% year-on-year to $30.76 billion, beating the analyst consensus estimate of $30.20 billion. The Refining segment ...
Electro Rent Corporation Declares Regular Quarterly Cash Dividend VAN NUYS, Calif.--(BUSINESS WIRE)-- Electro Rent Corporation (Nasdaq: ELRC) announced today that its Board of Directors has ...
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 ...
