Abstract

The invention belongs to the technical field of vertical internal-series graphitizing furnaces, and particularly relates to a vertical internal-series graphitizing furnace for a graphite recarburizingagent. The vertical internal-series graphitizing furnace comprises a furnace body and a power transmission line outside the furnace body, wherein the interior of the furnace body is separated into aplurality of heating areas by uprightly arranged heat insulation walls; the inner wall of a furnace roof in the heating areas is provided with first conducting poles; a furnace bottom in the heating areas is provided with second conducting poles; the bottoms of the second conducting poles are connected with compaction oil cylinders, which pass through the furnace body, through insulating backing plates; the conducting poles in adjacent heating areas are connected in series through conducting band arranged in the manner of penetrating through the heat insulation walls and cooperate with carbonrods and the power transmission line to form a power supply circuit; the conducing poles are provided with grooves used for mounting the carbon rods; further, the peripheries of the grooves of the second conducting poles are provided with conducting rods. The vertical inside-series graphitizing furnace is simple in structure and ingenious in design, can be used for effectively guaranteeing that multiple carbon rods are subjected to a graphitization process at the same time, and moreover, is used for guaranteeing that a series circuit in the graphitizing furnace is not cut off and the production efficiency is improved.

Description

[0001] The invention belongs to the technical field of vertical internal series graphitization furnaces, in particular to a vertical internal series graphitization furnace for a special graphite recarburizer. Background technique [0002] The vertical inner series graphitization furnace connects several carbon rods in series and places them between two conductive electrodes, and electrifies the circuit formed by them. The carbon rods are energized to generate heat and graphitized in a high-temperature environment formed by a large amount of heat dissipation. Since the carbon rod will stretch or expand during the graphitization process, it is necessary to use a compression mechanism to squeeze the carbon rod between the conductive electrodes to ensure its continuous power supply. However, due to the different coefficients of stretching or expansion of each carbon rod, there will be an extreme phenomenon that the pressing mechanism will break the carbon rod, and the inner series ...

Problems solved by technology

However, due to the different expansion and contraction coefficients of each carbon rod, there will be an extreme phenomenon that the pressing mechanism will break the carbon rod, and the inner series graphitization furnace in the prior art mostly uses multiple series electrodes to connect multiple electrodes in series The carbon rods are heated at the same time. Once a certain carbon rod in series is broken, all the carbon rods will be cut off, and the production can only be stopped for maintenance.
