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.
