Aluminium Expo | Guochao Aluminum's 200,000-ton Annual Production Project of New Energy Battery Aluminum Foil Blanks Successfully Ignites and Heats the 1850mm Gas-Cushion Continuous Heat Treatment Furnace

In the construction plant of Guochao Aluminum's 200,000-ton annual production project for new energy battery aluminum foil blanks, a loud "Ignite!" signaled the beginning of a crucial phase. The 1850mm gas-cushion continuous heat treatment production line, spanning 261 meters from west to east, saw rows of blazing flames inside the heat treatment furnace (hereinafter referred to as the "heat treatment furnace"). This marks the official start of Guochao Aluminum's heat treatment furnace, entering the baking and commissioning phase, taking a solid step towards thermal load commissioning production.

According to Aluminium Expo, the 1850mm gas-cushion continuous heat treatment production line is a large aluminum alloy strip heat treatment line primarily producing high-performance aluminum alloy strips in the 1, 3, 5, and 8 series. The production line is equipped with an uncoiler, sewing machine, disc shear, aluminum strip cleaning device, annealing furnace, high-performance water quenching device, looper, tension leveler, and coiler. It boasts complete functions for trimming, cleaning, annealing, and finishing, specifically processing wide aluminum alloy strips with a thickness of 0.4-2.5mm. Once fully operational, this production line will have an annual capacity of 104,000 tons, providing qualified thin strip products for key areas such as new energy vehicles, marine vessels, aerospace, and chemical products.

As a key project milestone in Guochao Aluminum's 200,000-ton annual production project for new energy battery aluminum foil blanks, Guochao Aluminum formed a project team with the Guangxi Advanced Aluminum Processing Innovation Center to ensure the successful ignition of the heat treatment furnace. The team proceeded with the baking and commissioning work in a tense yet orderly manner, conducting a comprehensive and meticulous inspection of the equipment during commissioning to ensure the stability of the furnace structure and uniform temperature distribution. According to the predetermined temperature commissioning plan, the furnace temperature of the heat treatment furnace steadily increased at a rate of 80℃/h, successively reaching 150℃, 300℃, and 460℃. On the morning of June 3, it rose to 570℃ and maintained this temperature for 5 hours, then slowly increased to the maximum temperature of 600℃ at a rate of 30℃/h and held for 1 hour before entering a natural cooling state. With the concerted efforts of the project team, all data indicators of the heat treatment furnace met the expected targets, and the commissioning work was successfully completed.
