Abstract

The invention belongs to the field of manufacturing and processing of a graphite material, and particularly relates to a graphitizing method and a graphitizing device of a graphite product. The graphitizing method of the graphite product comprises the following steps: preparing a furnace body, paving the bottom of the furnace body, surrounding a furnace core, padding a bottom pad layer, assemblinga product, filling with a resistance material, covering a top pad layer, covering a reaction material and a heat-insulating material, performing power transmission and cooling. According to the method, a plurality of Acheson graphitizing furnaces are connected in parallel and power transmission is conducted simultaneously. By the graphitizing method of the graphite product, the graphite product with high quality and high yield can be obtained, the comprehensive productivity is improved and the electric energy is saved.

Description

technical field [0001] The invention belongs to the field of manufacturing and processing of graphite materials, and in particular relates to a graphitization method and a graphitization device for graphite products. Background technique [0002] In the process of graphite production, graphitization is a very critical process. After high temperature heat treatment above 2300 ℃, it determines the physical and chemical properties of graphite products. The carbon atoms in the graphite calcined product are transformed from the thermodynamically unstable "two-dimensional disorderly overlapping" arrangement to the "three-dimensional ordered overlapping" arrangement, which makes the product's thermoelectric conductivity, thermal shock resistance, chemical stability, The anti-oxidation performance, lubricity and wear resistance are further improved, impurities are excluded to improve the purity, and the hardness is reduced to facilitate machining. [0003] At present, the demand fo...
