WebMay 31, 2012 · An electroslag remelting process (ESR) starts when the lower tip of a consumable electrode is immersed into a pool of molten slag. The premelted slag … The electroslag remelting (ESR) process is used to remelt and refine steels and various super-alloys, resulting in high-quality ingots. This process can be started up through vacuum induction melting. The ESR process uses the as-cast alloy as a consumable electrode. Electric current (generally AC) is passed … See more 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 See more • Vacuum induction melting See more • Ensuring Mold Steel Polishability at moldmakingtechnology.com • Electro-slag remelting furnace for consumable electrodes and having an electrode drive United States Patent 4394765 at freepatentsonline.com See more
WebThey demonstrate the comprehensive capabilities of the model in predicting the behavior of the ingot and slag during the entire process and properties of the final ingot produced. Such analysis can benefit the optimization of existing process schedules and design of new processes for different alloys and different ingot sizes. Electroslag Remelting WebElectroslag welding (ESW) is a highly productive, single pass welding process for thick (greater than 25 mm up to about 300 mm) materials in a vertical or close to vertical position. (ESW) is similar to electrogas …
WebThere are only two established remelting methods; Electroslag Refining (ESR) and Vacuum Arc Remelting (VAR). The principles of both techniques have been described elsewhere(2). ESR has been the dominant process in Europe whereas VAR has been the dominant process in USA. Accordingly process control technology for WebElectrogas welding (EGW) is a continuous vertical position arc welding process developed in 1961, in which an arc is struck between a consumable electrode and the workpiece. A shielding gas is sometimes used, but pressure is not applied. A major difference between EGW and its cousin electroslag welding is that the arc in EGW is not extinguished ...
WebOct 4, 2004 · Hi Rapid, Vacuum Arc Remelting is melting done under a vacuum. Its used for alloying elements that oxidise easily. Lots of uses for alloys made in this way in the airline industry. In the ESR process you take an ingot and pass an electric current through it. It slowly melts and drips through a slag and a new ingot is built up underneath.
