Electrode Paste, a carbon-based material, is used in the core of the majority of ore reduction furnaces around the world. It is the material responsible for transferring electricity during the smelting procedure. It also plays a key role in reducing oxides to ensure high-quality production. Technological advancements in electrode paste formulation, aiming for improved performance and cost-efficiency, are driving market expansion. Global economic trends and infrastructure development also play a key role in shaping the industry's trajectory.
The COVID-19 Pandemic had an impact on the global market. Lockdowns and restrictions temporarily reduced demand. After the COVID-19 outbreak, the global market experienced a temporary decline in demand due to lockdowns and restrictions. Ultimately, the global market continues to experience steady growth, owing to its critical applications in various sectors, including ferroalloy production and metal cleaning processes.
Soderberg's traditional electrode paste is made of 70 to 80 percent granular granular coal aggregate (calcined petroleum coke with graphite, or anthracite calcined from anthracite), along with a coal pitch binder. Once pressed against an electrode, it softens, and thermal conductivity increases as the carbonization process occurs. The carbon structure is becoming more ordered and, as temperature rises, thermal conductivity increases. When the paste reaches a temperature of 1473 K (1200 degrees Celsius), it is baked.
Detailed thermal property data are provided from room temperature up to 1073 K (800 degC), which capture the rapid changes in thermal properties as Soderberg electrode paste melts, heats up and eventually carbonizes. Thermal properties are determined by placing a mica sample and sensor assembly inside a 1.5 m ceramic tube. It was then sealed on both ends using water-cooled caps. The tube was heated by electrical resistance from an alternating current to the sample at a rate of 2
As expected, results showed that the prebaked paste was much more thermally conductive than the green binder and the 90°C softening points binders. The results show that the thermal diffusivity increases when temperature is increased and decreases if binder toughness is decreased, as expected.
AEEG electrode artifact is a major obstacle for prolonged AEEG monitoring in pediatric populations, especially as the study durations increase. This article shows how a conductive paste electrode with traditional paste reduces the artifact of AEEG in short-term child studies.
