ljusbågssmältning

ljusbågssmältning refers to the process of melting materials using an electric arc. This technique is employed in various industrial applications, most notably in steelmaking. In a submerged arc furnace, electrodes are lowered into a bath of material, and a high-current electric arc is generated between the electrodes and the material. This arc produces intense heat, which melts the substance. The temperature within the arc can reach several thousand degrees Celsius, allowing for efficient melting and refining of metals. The process is characterized by its high energy efficiency and ability to achieve very high temperatures. ljusbågssmältning is also utilized in welding, where a similar arc is used to fuse two metal pieces together. The precise control over the arc's intensity and duration is crucial for achieving desired results in both smelting and welding applications. Factors such as electrode material, current intensity, and the composition of the material being melted all influence the effectiveness of the ljusteknik.
