Vanadium extraction from steel slags is well studied, while extraction from secondary sources such as petcoke is not well understood. …
Liu et al [32]. studied the smelting process of vanadium slag replacing part of V 2 O 5 smelting ferrovanadium. Aluminum powder, silicon powder, V 2 O 5, vanadium slag and lime are added to the electric arc furnace for reduction. The composition of ferrovanadium produced meets the national standard, and the recovery rate of vanadium is 97.5 %.
Vanadium is an important transition metal which is widely applied in many fields due to its specific properties (Lee et al. 2003; Righter et al. 2016) (Rehder 2008) (Mukherjee et al. 2004).In the crustal, the vanadium content is in an average of 138 ppm ranged from 97 to 196 ppm (Roberta L. Rudnick and Fountain 1995; Yang et al. …
In the continuous casting process of steel, the bloom surfaces would experience intensive cooling from the water-cooled copper mold to secondary cooling water spray. If the cooling process is not controlled properly, hot ductility of the bloom surface microstructures would deteriorate, and bloom surface cracks would form easily under straightening deformation …
Vanadium (V) ore refers to a type of mineral deposit that contains vanadium, a chemical element with the atomic number 23 and the symbol V in the periodic table. Vanadium is a transition metal that is known for its high strength, excellent corrosion resistance, and ability to form alloys with other metals. Vanadium is commonly found in …
1. Introduction. Vanadium is an important transition metal used in the manufacture of high strength steel alloys, vanadium redox flow batteries, and catalysts [[1], [2], [3], [4]].In particular, in modern energy storage systems, a lot of demand is expected for vanadium redox flow batteries because they are relatively stable and have a better …
Abstract. Hardfacing materials with large chromium carbide are widely used in industry to increase the wear resistance of the component. Its manufacturing process is an important aspect of the overall economy of this technology. Inclusion of large chromium carbides in its microstructure makes these materials very difficult to machine.
In addition, direct reduction or direct processing of mineral-grade vanadium can be performed [14--16,19,39,40]. 4.1. ... According to the dressing process, the ore dressing machinery is divided into crushing, grinding, vibrating screens, sorting, and dewatering machines. Crushing machines include jaw crushers, rotary crushers, cone …
