Embodiment 1

[0058] A method for preparing niobium-iron alloy. The niobium sputtering target is crushed, then ground into a powder with a particle size of 40-80 mesh, and oxidized at a certain temperature of 380 degrees for 4.5 hours. After oxidation, the niobium sputtering target powder, aluminum powder, and iron powder 1. Lime is mixed evenly according to the mass ratio of 1:0.69:0.59:0.1, loaded into the preparation device, and then ignited for reaction. During the reaction, electrodes are installed to supplement heat, and aluminum powder is added as a reducing agent. The temperature is lowered to room temperature, the charge is poured out, the slag and ferroniobium alloy are separated, and crushed respectively to obtain ferroniobium alloy products and high-aluminum ferroniobium slag.

Embodiment 2

[0060] A method for preparing niobium-iron alloys. The niobium sputtering target is crushed, then ground into a powder with a particle size of 40-80 mesh, and oxidized at a certain temperature of 400 degrees for 4 hours. After oxidation, the niobium sputtering target powder, aluminum powder, iron powder, The lime is mixed evenly according to the mass ratio of 1:0.69:0.59:0.1, loaded into the preparation device, and then ignited for reaction. During the reaction, electrodes are installed to supplement heat, and aluminum powder is added as a reducing agent. After fifteen minutes, the reaction is over and the furnace charge is naturally cooled. After reaching room temperature, pour out the charge, separate the slag and ferroniobium alloy, and crush them respectively to obtain ferroniobium alloy products and high-aluminum ferroniobium slag.

Embodiment 3

Abstract

The invention provides a preparation method and device of a niobium-iron alloy, and relates to the technical field of niobium-iron alloys. The preparation method comprises the following steps: crushing a niobium sputtering target material, grinding into powder with the particle size of 40-80 meshes, oxidizing for 3.5-4.5 hours at a certain temperature of 380-420 DEG C, uniformly mixing the oxidized niobium sputtering target material powder, aluminum powder, iron powder and lime, filling the mixture into the preparation device, then igniting for reaction, in the reaction process, loading electrodes to supplement heat, adding aluminum powder to serve as a reducing agent, after 15 minutes, finishing the reaction, naturally cooling furnace burden to the room temperature, pouring the furnace burden out, separating furnace slag and the niobium-iron alloy out, carrying out crushing, and obtaining a niobium-iron alloy product and high-aluminum niobium-iron slag.

Description

technical field [0001] The invention relates to the technical field of ferroniobium alloys, in particular to a preparation device for ferroniobium alloys. Background technique [0002] Alloys are mixtures with metallic properties that are synthesized by two or more metals and metals or nonmetals by a certain method. Generally obtained by melting into a uniform liquid and solidifying, ferroniobium alloy is a kind of alloy, and it needs to be processed and produced by special preparation equipment in the production process of ferroniobium alloy. [0003] The inventors found that when the existing ferroniobium alloy preparation device is in use, it is not convenient to collect the materials inside the reaction furnace due to the deep depth inside the reaction furnace, and at the same time, a large amount of dust is easy to be generated during the alloy production process. affect the health of workers.
