On November 10, the 1850mm 4-high aluminum foil finishing mill (No. 5 mill) of a 6,000tpy battery foil project undertaken by Guizhou Guilv New Materials Co., Ltd. officially went into operation.
The trial production focused on a 16.5μm intermediate-rolling single-sheet specification. Operating at a rolling speed of 968 m/min, the first coil rolled off the line the same day, weighing 14.2 tonnes. The entire rolling process ran smoothly without any strip breakage. The coil edges were flat, free from quality defects such as tower shape or telescoping, and all indicators--including thickness deviation, flatness (shape), and surface quality--met technical standards.
