Crucible repair Copper crucible electroslag remelting (ESR) and pressure electroslag remelting (PESR) plants thanks to their high durability. The copper alloys used have been developed for all applications which place high to maximum demands on heat conductivity. In addition, a
On the other hand, the investments in stateoftheart technology such as Pressure Electro Slag Remelting (PESR), Vacuum Induction Melting (VIM) and Vacuum Arc Remelting (VAR) are the result of research showing a real need for a new generation of steels. Electroslag Remelting (ESR) is a secondary refining process used to further refine many alloys.
ESR is a process by which a consumable electrode is remelted utilizing heat generated by an electric current passing through a molten slag between the electrode and the 39NiCrMo3 low alloy steel
Electro Slag Remelting, widely known as. ESR is a proven secondary refining technology commercialised throughout the world, both for ferrous and nonferrous metals as well as alloys. Electro Slag Crucible melting, Electra Schlacke Winderstand (ESW), Electro Slag

For more information visit Electroslag Remelting Furnaces Background Consarc ESR Technology Breakthroughs In the 1960s Consarcs engineers conceived a new approach to elctroslag remelting, quite different from others in use at the time.
Electroslag remelting (ESR) furnaces are intended for production of highquality steel ingots of round, square and rectangular crosssections and also of hollow billets and shaped castings. Chuetsu manufacturers the copper crucible component in maintaining the functionality of this furnace. We offer: Builtup Type Crucible for (Square Type)
Freckles severely affect the quality of highcarbon chromium bearing steel ingots produced by electroslag remelting (ESR). With conventional slags, MgO, were premelted in a graphite crucible at 1 450#176;C for 1 h with Ar as a protective gas and then waterquenched. Quenched slags were dried at 120#176;C for 4 h, crushed into
In ESR, remelting is by resistance or ohmic heating resulting from an crucible, resulting in a chill cast layer. regions and hence thick slag skins. Attributes of ESR and VAR The effect of the differing attributes of ESR and VAR on some of the integrity
copper melting crucible used in the ESR (Electro Slag Remelting) and VAR (Vacuum Arc Remelting), US 10000 22000 / Piece, China, LMM, from Liaoning Mineral amp; Metallurgy Group Co., Ltd. on
Electroslag Remelting (ESR) is similar to VAR, but the steel is remelted in air by a molten refining slag, resolidifying beneath the slag layer. Both VAR and ESR produce steel ingots of very high quality. Today, VAR is an established and widely used method of producing high quality, large steel ingots throughout the world. ESR has been a
Electroslag remelting (ESR) and vacuum arc remelting (VAR) are two forms of vertical continuous casting used for nonferrous metals, superalloys, and specialty alloy sections up
Figure 1: Schematic illustration of Electroslag Remelting (ESR) operation. The ESCM (Electro Slag Crucible Melting) method was first invented by Borodin and coworkers in 1985 with inspiration from the ESR process [6, 16]. The main target was to design a system for remelting the scraps. The results of
Electro Slag Remelting under Vacuum (VESR) Remelting is carried out under vacuum as in VAR, however, using a slag. The advantages of both ESR and VAR are combined in one process. VESR Features O Combined process (VAR and ESR) O Avoid hydrogen and nitrogen pick up O No moisture from slag O No oxidation of the melt O Danger of white spots reduced to a minimum
VAR is the continuous remelting of a consumable electrode by means of an arc under vacuum. The main process stages O A consumable VAR electrode is generated by VIM, ESR, EB or plasma methods, assembled from titanium sponge, scrap or bulk, or by a prior VAR melt O DC power is applied to strike an arc between the electrode and the
In the ESR process the metal to be refined is an electrode dipping into the slag medium. The whole process is carried out in a water cooled copper crucible. An electrical current flow is applied through the electrode and subsequently the slag medium, ingot and bottom plate of the crucible. Since the slag has a lower electrical conduction than the
