en.Wedoany.com Reported - Recently, the world's widest and China's first (set) 3500mm copper and copper alloy wide and thick plate hot and cold rolling mill, installed by MCC Third Metallurgical, successfully passed its one-time commissioning test. The core installation task was completed one month ahead of schedule, with a 100% equipment commissioning qualification rate. This equipment, independently designed and manufactured by China First Heavy Industries, will comprehensively replace the old production line.
This hot and cold rolling mill is massive in scale, with the above-ground section standing 7.4 meters high, the underground foundation reaching a depth of 7 meters, and the total length of the mill line measuring 88 meters. It possesses dual functions for both cold rolling and hot rolling. Faced with challenges such as limited passage width in the installation plant area, soft ground foundations, and an ultra-heavy mill housing weighing 164.33 tons per piece, the project team from MCC Third Metallurgical innovatively adopted a combined solution of "600-ton hydraulic gantry crane + tank wheel transfer + winch traction," integrating composite techniques like the "tilting method" and "fulcrum load distribution + rotating vertical installation," controlling the installation error to within 0.1 millimeters.
During the construction process, the team integrated electrical automation and precision sensing technology into the heavy machinery installation. By establishing a full-process risk management and control system, they accurately identified 22 types of risk points and strictly implemented the "three inspection system," efficiently resolving issues such as anchor bolt deviations. The entire mill housing installation and commissioning took only 4 months, shortening the construction period by 50%, while achieving zero safety incidents and zero quality hazards.
The 3500mm hot and cold rolling mill is located within the plant area of Chinalco Luoyang Copper Processing Co., Ltd. in Luoyang, Henan Province, China, and belongs to the copper and copper alloy wide and thick plate production line. This production line has a total investment of 159 million yuan, was approved in June 2024, and took 22 months to construct and put into operation.
