Recent research led by SHAO Jian from the National Engineering Research Center of Advanced Rolling Technology at the University of Science and Technology Beijing has unveiled significant advancements in the cooling regulation of work rolls during the aluminum cold rolling process. This study, published in the journal ‘工程科学学报’ (Journal of Engineering Science), presents a sophisticated coupled heat transfer model that could have profound implications for the aluminum manufacturing industry and, by extension, the energy sector.
The research focuses on the multi-parameter coupled subsection cooling regulation characteristics of work rolls, which are critical components in the cold rolling of aluminum. By establishing a thermal conduction differential equation for both the work rolls and the aluminum strip, the team has successfully modeled the heat generated from strip deformation and friction. This model allows for a detailed examination of how various rolling parameters affect cooling efficiency.
One of the key findings of the study is the balance between positive and negative adjustment domains under the same rolling parameters, which is influenced by factors such as rolled length, header pressure, and friction coefficient. “The increase in these parameters enhances the cooling control ability, while higher rolling speeds tend to have the opposite effect,” SHAO explains. This nuanced understanding of cooling dynamics opens the door to optimizing production processes, potentially leading to reduced energy consumption and improved material properties of the rolled aluminum.
The implications of this research extend beyond mere efficiency. As manufacturers strive to meet growing demands for aluminum—particularly in sectors like automotive and aerospace—enhancing the cold rolling process could lead to significant energy savings. With energy costs being a critical factor in manufacturing, the ability to optimize cooling processes can translate into substantial financial benefits for companies.
Moreover, as industries increasingly focus on sustainability, the findings from this research could contribute to greener manufacturing practices. By optimizing the cooling process, manufacturers can not only increase their output but also minimize waste and energy usage, aligning with global efforts to reduce carbon footprints.
This innovative work by SHAO Jian and his team could shape future developments in aluminum processing technology, paving the way for smarter, more efficient manufacturing processes.
