Vanadium in Cold-rolled Sheet Steels
In hot rolled products, which are the subject of other presentations here, vanadium has been used for many years in high strength products, often in combination with other microalloying additions such as niobium or titanium. Vanadium can provide important contributions via both precipitation strengthening and ferrite grain refinement (due to austenite conditioning during thermomechanical proces...
متن کاملEvolution of Continuous Melting and Decontamination Technology for Dismantled Metal by an Induction Cold Crucible
An induction cold crucible melting is one of the most promising technologies for the reuse and decontamination of the radioactively contaminated metallic materials generated during the dismantling of nuclear facilities, because the crucible ensures a long life operation without generating secondary wastes. Fundamental equipment of the Melting and Recycling of Metals by Cold Crucible (MERC) proc...
متن کاملVitrification of Hlw Produced by Uranium/molybdenum Fuel Reprocessing in Cogema’s Cold Crucible Melter
The performance of the vitrification process currently used in the La Hague commercial reprocessing plants has been continuously improved during more than ten years of operation. In parallel COGEMA (industrial Operator), the French Atomic Energy Commission (CEA) and SGN (respectively COGEMA’s R&D provider and Engineering) have developed the cold crucible melter vitrification technology to obtai...
متن کاملCold crucible levitation melting of biomedical Ti-30 wt%Ta alloy.
Recently, titanium-tantalum alloys have been studied as implant materials for dental and orthopedic surgery. However, titanium and tantalum are difficult to mix by common arc melting and induction melting, because of their high melting point and the marked difference between their densities (Ti: 1,680 degrees C, 4.5 g/cm3, Ta: 2,990 degrees C, 16.6 g/cm3). Thus, the Cold Crucible Levitation Mel...
متن کاملProtection Mechanisms for Blast Furnace Crucible Using Titanium Oxides
In modern steelmaking the duration of a working campaign for a blast furnace is related to the life of the crucible. Adding titanium oxide has been a frequent practice in the operation routines for modern blast furnaces, seeking the protection of the crucible walls, independently from its physical or chemical characteristics. These practices, as conventional operation of iron and steelmaking in...
