This paper introduces how to improve the production process of common electrode paste and make special treatment on raw materials to produce excellent electrode paste with high strength, good thermal shock resistance, good sintering performance, low unit consumption and power saving
The A-phase electrode of 3 # calcium carbide furnace in the calcium carbide workshop had a soft break and paste leakage accident.
Reach the rated value, enhance the current resistance heat of the electrode paste baking in the electrode shell, and ensure the balance between the electrode baking amount and the electrode consumption speed.
Standard and non-standard electrode paste: standard electrode paste is mainly used for open ferroalloy furnace and medium and small calcium carbide furnace,
The electrode paste has high temperature resistance and low thermal expansion coefficient.
Carbon paste products can be divided into two categories, one is conductive materials (such as electrode paste and anode paste); One is the bonding filler used for masonry carbon (such as bottom paste, coarse joint paste and fine joint paste).
In the process of producing carbide, ferrosilicon, ferromanganese and other ferroalloys, the smelting temperature needs to be increased, which can meet the production requirements only by inputting a strong current into the furnace through special electrodes.
The inner wall of the escort barrel is designed with special materials, which is not bonded with electrode paste, but also a good insulator.
Electrode paste is used in open and closed submerged arc furnaces as a continuous self baking electrode to produce calcium carbide, ferroalloy and other products.
