通过优选电阻炉中毛坯热处理方式,可以降低石墨化电极生产的电能消耗。 在石墨化过程中,确定电极毛坯质量的决定性因素是最终的温度(不低于2800℃)。然而,石墨化制品处于炉子的不均匀温度场之中,快速加热受到石墨化制品自身热强度限制。制品的最后成型由多种因素决定,其中主要是石墨制品在“阿切绍纳”炉中被间接加热,而且最根本的取决于在炉中被加热的碳材料(毛坯和配料)的热物理特性和电物理特性与温度的关系。
By optimizing the heat treatment of the blank in the resistance furnace, the power consumption of the graphitized electrode can be reduced. In graphitization, the decisive factor in determining the quality of the electrode blank is the final temperature (not less than 2800 ° C). However, the graphitized product is in an inhomogeneous temperature field of the furnace, and the rapid heating is limited by the thermal strength of the graphitized product itself. The final shaping of the article is governed by a number of factors, chiefly the fact that the graphite article is indirectly heated in an “Arcehona” furnace and most fundamentally depends on the thermophysical properties of the carbon material (blank and furnish) being heated in the furnace Characteristics and electrical characteristics of the relationship between the temperature.
