Description

Technical Field

[0001] The utility model relates to the technical field of electrode baking, in particular to a calcium carbide furnace self-baking electrode device. Background Art

[0002] The self-baking electrode device for calcium carbide furnace is a special electrode system used in calcium carbide furnace. Its main components include electrode shell and electrode paste (also called electrode material). The characteristic of this device is that the electrode is gradually formed by self-baking during the operation of the electric furnace. Specifically, the production process of the self-baking electrode is as follows: First, the electrode paste (made of raw materials such as anthracite, coke, asphalt and tar) is loaded into the electrode shell installed on the electric furnace. As the electric furnace runs, the electrode paste in the electrode shell gradually undergoes physical and chemical changes at high temperature, such as the escape of volatiles, liquefaction, solidification and crystallization, and finally forms an electrode with certain strength and conductivity.
