Electroslag (ESR), or electroslag remelting, is a process used in metallurgy to refine metals, particularly steel and superalloys. In this process, the metal is first melted in a furnace, and then the molten metal is poured into a water-cooled mold through a slag bath. The slag acts as a purifier, removing impurities from the metal as it solidifies.
The main advantages of the electroslag process are:
– Improved material properties: It produces ingots with uniform composition and reduced defects.
– High-quality steel production: Often used for high-strength and specialized steels, such as those used in aerospace, power generation, and heavy machinery.
Electroslag remelting helps improve the quality of steel by enhancing its structural integrity, making it more suitable for critical applications.
