Recently, Yuefeng Aluminum Technology successfully completed the quality inspection of large-section aluminum round rods with a diameter of 19 millimeters and a single roll weight of 2 tons. The products have been dispatched to a certain energy storage battery production base in the Yangtze River Delta. This marks that Yuefeng Aluminum Technology has become the first enterprise in China to adopt the continuous casting and continuous rolling process and supply large-section aluminum round rods to the energy storage field on a large scale. It also means that this type of key material has achieved import substitution and entered the stable production stage.
Currently, the domestic energy storage industry is in a period of rapid development. Industry data shows that aluminum connection components, as the core auxiliary materials of energy storage battery modules, have a strong demand for large-section aluminum round rods with diameters of 17.5 millimeters and 19 millimeters and other specifications. However, due to high process barriers and difficult equipment compatibility, domestic large-scale production has long been in a blank state.
Previously, a leading energy storage battery enterprise in China urgently requested assistance from Yuefeng Aluminum Technology due to the interruption of the import channel and the emergency of the production line. Yuefeng Aluminum Technology quickly organized trial production and, after multiple rounds of experiments, successively overcame key technical problems such as the difference in cooling rate and surface scratches of large-section aluminum rods. The product size accuracy, surface quality, and internal structure all met the standard requirements.
This breakthrough has formed a set of "reverse process development" methodology, that is, to reverse from the terminal demand to determine the process parameters, systematically solve engineering bottlenecks, and accumulate replicable engineering experience for the development of larger specifications of products and applications in extreme working conditions such as ultra-high voltage and offshore wind power.
