Are you curious about the remarkable rise of graphitization furnaces in the world of graphite electrode manufacturing? As the demand for high-quality electrodes continues to surge, manufacturers are increasingly turning to innovative solutions to optimize their production processes.
Zhongsheng supply professional and honest service.
In this article, we delve into the fascinating reasons why graphitization furnaces are emerging as a prominent choice in the industry.
Graphitization can be divided into direct method and indirect method according to the heating method, and intermittent and continuous according to the operation mode. Graphitization process is an important process for the production of graphite electrode.
To graphitize the electrode, the processing equipment – graphitization furnace is used. Currently, Acheson graphitizing furnaces and endothermic series connection (LWG) furnaces are widely used. However, in addition to these two furnace types, there are several other furnace types for graphitization, which will be introduced to you one by one:

1. Acheson graphitizing furnace
Acheson graphitization furnace by heating method, it belongs to the direct heating type electric furnace. Direct heating type furnace is the product itself is a conductive body, through the resistance heating, so that the product completed graphitization. Atchison graphitizing furnace is one of the main furnaces for producing high purity graphite in China, which has long production cycle, high energy consumption, low efficiency and intermittent production. The electricity consumption of Acheson graphitization furnace is about ~kwh/t.
2. Internal string graphitization furnace
The main difference between the internal string graphitization process and the Acheson graphitization process is that the product is heated directly through the electrode itself, without the need for resistive material to generate heat. This is the main feature that improves the internal string graphitization process over the Acheson graphitization process. Since the internal string graphitization process has no filler material and thus can reduce the heat carried out, the internal string graphitization furnace is characterized by high thermal efficiency and short power delivery time.
