en.Wedoany.com Reported - A key project for quality improvement, capacity expansion, and equipment upgrade at China Zhonglv Luoyang Copper Processing Co., Ltd. recently reached a critical milestone. The first cold rolling trial of the 3500mm copper and copper alloy wide and heavy plate hot/cold rolling mill was completed ahead of schedule. For this trial, T2 copper plate was selected as the test billet. The slab thickness was reduced from 118mm to 18mm through multiple passes of precision rolling, achieving a total processing rate of 84%. The tolerance consistency met customer requirements, and the maximum rolling force reached 68% of the designed capacity. This comprehensively verified that the equipment's heavy-load rolling capability fully meets the established design targets.
This 3500mm wide and heavy plate mill is a core piece of equipment for deep processing of high-end copper products, integrating both hot and cold rolling functions. The equipment is equipped with an intelligent rolling control system, positive/negative bending roll control technology, and is paired with the industry-advanced sled rolling control process. It enables micron-level precise adjustment of roll gaps and real-time control of rolling pressure throughout the process, effectively managing plate shape regularity and preventing plate edge warping (crowning or dishing). This specifically addresses common industry challenges such as uneven thickness and plate shape fluctuations that easily occur during the rolling of wide copper plates. The technical team developed a detailed trial run plan in advance, refined the rolling procedures, and scientifically planned the rolling passes. They closely monitored the equipment's operating status throughout the trial. The mill ran smoothly with precise control of all parameters during the entire trial, providing dual assurance in both hardware and process for efficient, stable, and first-pass qualified rolling.
The success of this first trial not only comprehensively verified the operational reliability of the core equipment but also accumulated valuable practical experience and fundamental process data for subsequent large-scale production. The next step involves initiating specialized trial rolling for cold-rolled plates in specifications from 8mm to 3mm. The project team will continue to explore and optimize core rolling process parameters to further enhance rolling efficiency and product forming quality. Simultaneous trial production will help alleviate the production load pressure on the existing production line. Currently, installation and commissioning of other supporting equipment for the production line are progressing efficiently in parallel. The overall project is steadily advancing according to plan, striving towards the goal of full-line commissioning and production.
Currently, Zhonglv Luoyang Copper Processing Co., Ltd. is a core copper processing enterprise under the China Aluminum Corporation (Chinalco), responsible for the supply guarantee of copper materials for major national projects. Upon full-line commissioning, this project will significantly enhance the independent production capacity of wide copper and copper alloy plates and strengthen the stability of the high-end copper material supply chain.
