Electro Slag Remelting (ESR) Refining and Solidification Control Electro Slag Remelting Furnace Model F240 Electro Slag Remelting (ESR) The Electro Slag Remelting process in general is very similar to the VAR process. In ESR the ingot is formed under a superheated slag in which the electrode is immersed and melted off using an alternating current. Remelted ingots are free from porosity, macro-segregation and contain minimum content on non metallic inclusions. Accessories that increase flexibility and range of application: OO Automatic gas-inlet system OO Slag and material feed system OO...

Multiple Purpose Remelting (VAR, ESR, PESR, IESR VESR) VAR/ESR Furnace Model R240 Multiple Purpose Remelting (VAR, ESR, PESR, IESR, VESR) Different remelting processes can be carried out in one chamber type furnace using alternating or direct current to remelt one consumable electrode into one ingot above or below atmospheric pressure. Accessories that increase flexibility and range of application: OO Automatic gas inlet OO Automatic pressure control OO Slag and material feed system OO Automatic guidance of the electrode ram OO Magnetic coil for electromagnetic stirring OO Electrode welding...
