One Of The High Level Metals Vanadium Pentoxide Flake

A method for melting vanadium pentoxide flakes comprises the following steps: heating the melting chamber, heating the melting chamber to a temperature of 700 °C to 1000 °C through the alternating magnetic field generated by the induction coil of the electromagnetic heating device; blanking, the powder vanadium pentoxide is transported to the melting chamber; Melting, under the condition that the electromagnetic heating device maintains the melting temperature in the melting chamber and the oxygen delivery device of the melting chamber gives oxygen, the vanadium pentoxide is melted in the melting chamber, discharged, and the vanadium pentoxide is melted and discharged through the discharge port of the melting chamber. It provides a method of melting vanadium flakes with low energy consumption, high yield, short melting time and no pollution to the environment.

1. A vanadium pentoxide flake sampler and vanadium sampling assembly belong to the technical field of sampling device. The vanadium sampler comprises a hollow first tube with an opening at one end, a second tube that can be rotated relative to it is sleeved on the first tube, at least one first sampling hole is formed in the first tube, a second sampling hole is formed in the second tube that is matched with the first sampling hole to communicate inside and outside the first tube when rotating, at least one first partition plate is also arranged in the first tube, and the first partition plate separates the inner part of the first tube into at least two sampling chambers. The vanadium sampler provided by the utility model can adapt to the sampling operation of the finished vanadium in the form of a sheet, and the sampling efficiency is high, and the sampling representativeness is good. The utility model also provides a vanadium sampling assembly comprising above-mentioned vanadium sampler.
