Nowadays, overpopulation and rapid development of industries and lifestyle lead to an increase in the consumption of natural resources and reduction of their resource. On the other hand, humans have always produced waste and disposed it in some way, which influence the environment.

When considering the quest for clean steels, it is essential to consider the remelting processes, vacuum arc remelting (VAR), and electroslag remelting (ESR) (sometimes, perhaps for marketing purposes, these remelting processes are called instead refining processes).

The processes can be preceded by vacuum induction Cited by: 3 Remelting. Remelting processes are used to improve the quality of ingots cast from primary melting. This benefits alloy chemistry as well as facilitating the hot-working processes.

Since the remelting processes involve only a small molten pool at any given time, chemical segregation is minimized and the alloy grain size is controlled. Efficient Remelting (Fry's Metals) n.d. Efficient Remelting (Fry's Metal Foundries) n.d.

Electroslag Remelting Process: Part One Abstract: Electro Slag Remelting (ESR) is a process used for remelting and refining of steels and special alloys which are used for critical applications in aircraft, thermal and nuclear power plants, defense hardware, etc. The efficiency of electroslag remelting (ESR) and the quality of the remelted steel depend to a large extent on the methods used to obtain the consumable electrodes Author: V.

Chernyh, I. Marchenko, I. Blohin, G. Molodan, V. Oleinichenko, P. Rudometkin, G. The concentration of O, the major impurity in Ti scrap, inevitably increases after remelting, and thus, high-grade Ti ingots cannot be produced only from Ti scrap.

In the practical alloy production process, the O concentration in Ti alloys is suppressed by remelting the Ti scrap with a virgin Ti sponge with a low O : Osamu Takeda, Toru H. Okabe. Boris Medovar, a member of the Soviet Academy of Sciences, is a promi­ nent member of the E.O.

We cannot make engines more efficient Diverting scrap is better than recycling because it avoids remelting the metal which would cause increased CO2 emissions.

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, etc.

The electroslag remelting (ESR) process is used to remelt and refine steels and various super-alloys, resulting in high-quality ingots. It is a thorough update of the author's previous books "Castings 2nd Edition" and "Castings Practice: the 10 Rules of Casting" both published by Elsevier.

View Show abstract. Steelmaking is the process of producing steel from iron ore and/or steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.

The Paton Institute, internationally famous for its entrepreneurial efforts in electrical welding. Resistance welding is a process used to join metallic parts with electric current.

There are several forms of resistance welding, including spot welding, seam welding, projection welding, and butt welding. The heat generated is expressed by the equation i. E = I2Rt. FSE is particularly energy efficient as it results in the least primary energy demanding approach.

To be more specific, the FSE implementation (ID3) allows a reduction in energy demand as high as 74% and 63% with respect to the remelting and the ECAP routes, by: 3.

The range of useful books and other publications on furnace engineering, thermodynamics and process engineering is vast.

What makes this book unique is a specific focus on aluminum recovery, rather than just recycling in general.

It also offers an integrated discussion of scrap recovery and re-melting operations and includes economic as well as technical elements of recycling. Important topics include a discussion of the scrap aluminum marketplace and how secondary a.

By remelting under inert gas the oxide cleanliness can be further improved. For further optimisation of microscopic purity, the vacuum arc remelting procedure is used.

When their complete life cycle is taken into account, from the production of raw material to the recycling of used parts, aluminium construction products make efficient use of energy and resources.

Studies conducted on specific applications have shown that the energy and environmental benefits of aluminium can be substantial. An induction furnace is an electrical furnace in which the heat is applied by induction heating of metal. Induction furnace capacities range from less than one kilogram to one hundred tonnes, and are used to melt iron and steel, copper, aluminium, and precious metals.

The advantage of the induction furnace is a clean, energy-efficient and well-controllable melting process compared. Melting Operations Perryman’s melting facility employs Electron Beam Cold Hearth Melting (EB) and Vacuum Arc Remelt (VAR) technologies, both of which operate under vacuum.
