Title: Bertil Waldèn: Innovator in Metal Alloy Refinement
Introduction: Bertil Waldèn is an inventor based in Sandviken, Sweden. He has made significant contributions to the field of metal alloy refinement. Although he currently holds no granted patents, his work in this area is noteworthy.
Latest Patent Applications: Bertil Waldèn has submitted a patent application titled "A Process for Refining a Nitrogen-Containing Metal Alloy." This process involves refining a nitrogen-containing metal alloy using arc remelting of a consumable electrode in a furnace. The method includes providing a consumable electrode of the metal alloy, a second electrode, and a controlled atmosphere within the furnace. An arc is struck between the consumable electrode and the second electrode to melt the consumable electrode, forming a molten metal alloy pool. The process maintains the arc between the consumable electrode and the molten metal alloy pool, delivering the molten metal alloy into a mold to cast an ingot of refined metal alloy. The controlled atmosphere is achieved by flowing argon gas through the furnace at a pressure of 1-500 Pa.
Conclusion: Bertil Waldèn's innovative approach to refining metal alloys showcases his expertise and potential impact in the field. His ongoing work may lead to significant advancements in metal processing technologies.
