Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a preparation method for producing graphite materials using an Acheson graphitization furnace, which can effectively produce graphite materials with stable quality, avoiding unstable and highly volatile product quality. problems, and can effectively prevent the pollution of the environment caused by the generation of effective gas, which solves the problem of uneven temperature distribution in the radial and axial directions of the graphitization furnace when the Acheson graphitization furnace produces graphite materials. The gradient is large. With the emergence of fine particle structure, large products, and large cross-section furnace cores, the temperature gradient is greater, so the quality of the product is unstable and fluctuating. The raw material for the production of graphite materials is petroleum coke, and its sulfur content Higher, a large amount of harmful sulfur-containing gases will be produced during the graphitization process, causing environmental pollution problems

Abstract

The invention relates to the technical field of graphite production and discloses a preparation method for producing a graphite material by using an Acheson graphitization furnace. The preparation method comprises the following steps: I, preparing an Acheson graphitization furnace, laying a first heat-preservation layer at the bottom of the Acheson graphitization furnace, and further laying a quartz feldspathic sand hearth of 5-7cm at the top of the first heat-preservation layer; II, placing a plurality of partitioning plates at the top of the quartz feldspathic sand hearth, forming a circle by the plurality of the partition plates, encircling a graphite furnace core to be produced, and further laying a bottom pad layer among the encircled partition plates; III, placing cokes on the bottompad layer, and forming material piles among multiple cokes. By adopting the preparation method for producing the graphite material by using the Acheson graphitization furnace, the graphite material of stable quality can be effectively produced, problems of quality instability and large quality fluctuation of a product is avoided, and the problem that the environment is polluted by effective gasescan be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of graphite material production, in particular to a preparation method for producing graphite material with an Acheson graphitization furnace. Background technique [0002] In the graphite production process, graphitization is a very critical process. After high-temperature heat treatment above 2300 ° C, it determines the physical and chemical properties of graphite products. The carbon atoms in the graphite roasted product are transformed from the thermodynamically unstable "two-dimensional disorderly overlapping" arrangement to the "three-dimensional orderly overlapping" arrangement by thermal activation, which makes the product's thermoelectric conductivity, thermal shock resistance, chemical stability, Anti-oxidation performance, lubricity and wear resistance are further improved, impurities are removed to improve purity, and hardness is reduced to facilitate machining. The specific process is to fill t...
