bågsmältning
Bågsmältning, also known as arc melting, is a process used to produce high-purity metals and alloys. It involves the use of an electric arc to melt and fuse materials. The process typically occurs in a vacuum or inert gas environment to prevent contamination. The materials to be melted are placed in a water-cooled copper crucible, which is then subjected to a high-voltage electric arc. The intense heat generated by the arc melts the materials, which can then be cast into ingots or other desired shapes. Bågsmältning is commonly used in the production of metals such as titanium, zirconium, and other reactive metals that are difficult to produce using traditional methods. The process allows for precise control over the composition and purity of the final product. The resulting ingots can be further processed through techniques such as hot isostatic pressing or extrusion to achieve the desired properties.
