Abstract

The invention discloses a heat-treatment furnace of powder. The heat-treatment furnace of the powder comprises a furnace shell with a closed furnace hearth, a crucible arranged in the closed furnace hearth and a heat-preserving cover arranged at the top end of the furnace shell; a charging opening is formed in the heat-preserving cover, and a discharging opening is formed in the bottom end of thefurnace shell; an induction coil is arranged between the external wall of the crucible and the internal wall of the furnace shell; and a rotating disk and a rotating shaft, which penetrates through the heat-preserving cover and is fixedly connected with the rotating disk, are arranged at the internal upper part of the crucible. According to the heat-treatment furnace of the powder, the continuousproduction of powder materials is achieved, the energy saving effect is good, and the heating efficiency is high.

Description

technical field [0001] The invention relates to a powder heat treatment furnace, which belongs to the field of material graphitization equipment. Background technique [0002] With the development of new energy and power, lithium-ion batteries are increasingly favored by investors. As a key component of lithium-ion batteries, the market for carbon anode materials is also facing blowout development. A key step in the production process of carbon anode materials is graphitization purification. Graphitization refers to the transformation of carbon atoms from random and irregular arrangement to a regular hexagonal planar network structure at high temperature, that is, graphite microcrystalline structure. The purpose is to obtain the properties of graphite with high electrical conductivity, high thermal conductivity, corrosion resistance, and friction resistance. The graphitization temperature can be as high as 3100°C. The higher the temperature, the more perfect the development...
