Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of materials engineering, and particularly to a method and system for optimizing the ratio of medium-temperature pitch for graphite electrodes. Background Art
[0002] As an important consumable in the electric arc furnace smelting process, graphite electrodes are widely used in industries such as steel and aluminum smelting. The quality of graphite electrodes directly affects the stability and efficiency of the smelting process. Therefore, ensuring the production quality of graphite electrodes is the key to improving smelting production efficiency and reducing costs. The manufacture of graphite electrodes mainly relies on high-quality raw materials and precise mixing ratio processes, especially the mixing ratio of pitch and graphite powder. During the production process, the medium-temperature characteristics of pitch play a crucial role in the performance of the electrodes. Therefore, how to optimize the ratio of pitch and graphite powder, especially the ratio of medium-temperature pitch, has become an important research topic in the production of graphite electrodes.
[0003] In the prior art, during the production process of graphite electrodes, the ratio of pitch to graphite powder mostly relies on experience or manual adjustment, lacking an effective automated system. This traditional ratio method has multiple problems, including a lag in response to changes in temperature, humidity, and raw material composition during the production process, resulting in inaccurate ratios and further affecting the performance and quality of the electrodes. In addition, in the traditional production process, the medium-temperature characteristics of pitch are insufficiently controlled and regulated, and the influence of temperature on the properties of pitch such as fluidity and adhesiveness cannot be fully considered, resulting in poor product consistency and low qualification rates.
[0004] With the continuous development of industrial automation technology and intelligent control systems, more and more enterprises seek to improve the production efficiency and product quality of graphite electrodes through scientific and reasonable ratio optimization methods. However, existing graphite electrode ratio optimization systems often can only be adjusted according to fixed empirical parameters, failing to fully combine real-time monitoring data and dynamic changes in the production environment, lacking precise control and optimization for the ratio of medium-temperature pitch. Therefore, the technical personnel in this field have provided a method and system for optimizing the ratio of medium-temperature pitch for graphite electrodes to solve the problems raised in the above background art.
