Copper Crucibles for ESR Electroslag remelting (ESR) furnaces
Electroslag remelting (ESR) furnaces are intended for production of high-quality steel ingots of round, square and rectangular cross-sections and also of hollow billets and shaped castings. Chuetsu manufacturers the copper crucible component in maintaining the functionality of this furnace.
We offer:
Built-up Type Crucible for E.S.R. (Square Type)
Assembly Crucible for Ingot (Withdrawal Type)
Electroslag Remelting (ESR) ingot production is widely used in the United States to refine nickel and cobalt based alloys for aerospace applications. The process is less widely used for stainless, carbon, and low-alloy steels. It provides some advantages for production of large ingots for gears, rolls, rotors and dies. ESR is also used as a secondary remelting process for high-alloy and specialty steels, i.e., tool steels. ESR may be employed to produce ingots of certain hard-to-machine refractory, reactive, and heavy metals such as titanium, zirconium, molybdenum. The advantage in this later application is that the high surface qualities achieved can significantly reduce machining requirements.

Copper crucibles for VAR furnace vacuum arc remelting furnace
VAR is used most frequently in high value applications. Because it is both time consuming and expensive, a majority of commercial alloys do not employ the process. Nickel, titanium, and specialty steels are materials most often processed with this method. The conventional path for production of Titanium alloys includes single, double or even triple VAR processing.[2] Use of this technique over traditional methods presents several advantages:
The solidification rate of molten material can be tightly controlled. This allows a high degree of control over the microstructure as well as the ability to minimize segregation
The gases dissolved in liquid metal during melting metals in open furnaces, such as nitrogen, oxygen and hydrogen are considered to be detrimental to the majority of steels and alloys. Under vacuum conditions these gases escape from liquid metal to the vacuum chamber.
Elements with high vapor pressure such as oxygen, carbon, sulfur, and magnesium (frequently contaminants) are lowered in concentration.
Centerline porosity and segregation are eliminated.

Copper crucibles for Vacuum Arc Remelting (VAR)
Copper Crucibles for VAR :
Vacuum Arc Remelting (VAR), a technology typically utilized for the production of titanium, nickel and steel ingots, require copper crucibles to maintain it's function. Our Copper Crucibles are manufactured by forging as one solid piece with flange. without welding. The benefit of this method is that the service life and integrity of one solid piece is considerably longer than that of conventional crucibles fabricated by welding.
