We all know that electrode paste is an indispensable raw material for smelting alloys and producing calcium carbide in furnaces. However, the quality of electrode paste varies for alloy plants. How do we measure the quality of electrode paste? Before getting the right answer, let’s first understand the various indicators of electrode paste and the impact of its use in furnaces
- Moisture content: The moisture content in the electrode paste should meet the standards. Too high a moisture content will affect the sintering performance and density of the electrode paste, while too low a moisture content will lead to an increase in the amount of carbon residue during sintering of the electrode paste.
- Volatile content: The volatile content of the electrode paste should be controlled within a certain range to ensure good sintering performance and sufficient density during the sintering process of the electrode paste.
- Ash content: The ash content of the electrode paste should comply with the standard. Too high an ash content will affect the conductivity and corrosion resistance of the electrode paste, while too low an ash content will lead to an increase in the amount of carbon residue during sintering of the electrode paste.
- Particle size: The particle size of the electrode paste should meet the standard. If the particle size is too small, it will affect the sintering performance and density of the electrode paste, while if the particle size is too large, the amount of residual carbon will increase during sintering of the electrode paste.
- Thermal stability: The electrode paste should have good thermal stability, that is, it is not easy to decompose and deteriorate at high temperatures to ensure that the electrode paste can work stably at high temperatures.
- Conductivity: The electrode paste should have good conductivity to ensure smooth transfer of energy when current passes through.
- Corrosion resistance: The electrode paste should have good corrosion resistance to resist erosion by various chemicals.
- Environmental performance: Electrode paste should meet environmental protection requirements and contain no substances harmful to the human body and the environment.
The mentioned indicators of electrode paste provide us with a very intuitive understanding of its characteristics. In fact, based on Saxin’s years of experience in supplying electrode paste to various alloy plants globally, these indicators are just one aspect of measuring the quality of electrode paste. The quality standards for electrode paste are actually determined based on the customer’s furnace. Electrode paste is a non-standard product, and at Saxin Carbon, we generally customize the specifications according to the customer’s ore-hearth furnace and smelting products. As long as it matches the customer’s furnace for electrode paste production, it is considered high-quality electrode paste
