The effect of electrode paste sintering on the production efficiency of calcium carbide furnace

The sintering of electrode paste has a significant impact on the production efficiency of calcium carbide furnace, mainly manifested in the following aspects:

Conductivity: Good electrode paste sintering can form a dense electrode structure, improve its conductivity, thereby reducing energy loss and improving the energy efficiency of calcium carbide furnaces.

Electrode consumption rate: The degree of sintering of the electrode paste directly affects the service life of the electrode in the calcium carbide furnace. If the sintering is poor, the electrodes may be consumed too early, leading to production interruption and increased frequency of electrode replacement, thereby reducing production efficiency.

Sintering density: A higher sintering density can enhance the structural strength of the electrode, reduce electrode fracture caused by mechanical vibration or other external forces at high temperatures, and improve the operational stability of the calcium carbide furnace.

Antioxidant performance: A good sintering process can improve the antioxidant capacity of electrode paste, prolong the service life of electrodes at high temperatures, and indirectly improve the production efficiency of calcium carbide furnaces.

Heat conduction: Optimized sintering process can improve the heat conduction efficiency of electrodes, which is beneficial for controlling the temperature distribution in the calcium carbide furnace and accelerating the melting process, thereby improving production efficiency.

To achieve the best sintering effect, the following factors usually need to be considered:

The composition and quality of electrode paste;
Sintering temperature and its control;
Sintering time and heating rate;
The compatibility between electrode paste and calcium carbide furnace;
Maintenance and repair during the production process.
Taking these factors into consideration and making appropriate adjustments and optimizations can maximize the performance of the electrode paste, thereby improving the production efficiency of the calcium carbide furnace.
