30+ YEARS OF EXPERIENCE IN CARBON INDUSTRY

In the world of submerged arc furnaces and electrothermal operations, the unsung hero is often the Electrode Paste. This self-baking consumable is the vital link that powers the entire smelting process, making its selection, quality, and performance paramount to your operational efficiency and bottom line. Understanding the nuances of electrode paste can mean the difference between seamless production and costly downtime.

What is Electrode Paste?
Electrode Paste, also known as Furnace Repair Electrode Paste, is a conductive material primarily composed of carbonaceous aggregates like calcined anthracite or coke and a binder. It is used to create the continuous Söderberg electrodes that are essential for ferroalloy, calcium carbide, and silicon metal production. The choice between Calcined Coke Electrode Paste and Anthracite Electrode Paste depends on specific furnace requirements, with calcined coke grades often offering superior conductivity for high-intensity operations.

Choosing the Right Shape for Your Furnace
The physical form of the electrode paste is crucial for smooth feeding and consistent baking. We offer a variety of shapes to match different feeder systems and ensure optimal performance:
Trapezoidal Electrode Paste: Designed for easy handling and a stable descent within the electrode shell, minimizing the risk of bridging.
Egg-shaped Electrode Paste: This aerodynamic shape promotes a more uniform flow and is excellent for preventing hanging and ensuring consistent consumption.
Cylindrical Electrode Paste: A common and versatile form that provides reliable performance in a wide range of standard furnace setups.
Common Operational Challenges and Solutions
Even with high-quality paste, operators can face issues that impact productivity. Here’s how to address the most frequent problems:
Electrode Paste Breaking: This serious issue can halt production. It is often caused by inconsistent paste quality, improper baking parameters, or thermal shock. Ensuring a uniform electrode paste formulation with the correct volatile matter and a controlled baking cycle is key to preventing fractures.

Electrode Paste Shedding: When pieces of the paste dislodge and fall into the charge, it can contaminate the melt and disrupt the process. Shedding is frequently linked to poor caking properties or a mismatch between the paste's softening point and the furnace temperature.
Electrode Paste High Consumption: Unexpectedly rapid paste usage drives up costs. This can result from excessive current density, oxidation at the electrode tip, or using a paste grade that is too soft for the operating conditions. Selecting a high-density, oxidation-resistant paste is critical for control.
Electrode Paste Caking: Also known as "hanging," this occurs when the paste fails to descend smoothly in the shell. It can be caused by a formulation with inadequate plasticity or by large particle segregation. A well-balanced formulation ensures a steady, predictable slip.
The Rise of Direct Current Electrode Paste
With the growing adoption of DC arc furnaces in metallurgy, the demand for specialized Direct Current Electrode Paste is on the rise. DC operations place different thermal and electrical stresses on the electrode, requiring a paste with tailored electrical resistivity, thermal conductivity, and baking characteristics to function as a stable cathode or anode.
