At 18:18 on October 15, the second phase of Yangjiang Hongwang’s three-stand continuous rolling and continuous de-pickling combined unit with an annual output of 500,000 tons went on trial production. The output product has a fine surface, uniform color, and performance such as roughness and hardness meet the expected indicators.
Yangjiang Hongwang’s three-stand continuous rolling and continuous stripping pickling combined unit adopts advanced black-skin direct rolling technology, which can produce 2E semi-finished products with a thickness of 1.15mm to 3.0mm, which is Yangjiang Hongwang’s four-stand continuous rolling and continuous stripping and pickling The combined unit and the 20-high cold rolling mill, as well as the Zhaoqing Hongwang five continuous rolling and supporting continuous annealing and pickling unit and the 20-high cold rolling mill provide better raw materials.
The 2E semi-finished product produced by the three-stand continuous rolling and continuous de-pickling combined unit has a finer surface roughness, a more uniform surface color, a better grain size index, fewer head and tail defects, and a better shape than ordinary NO.1 raw materials. More effective control. Subsequent cold rolling mills and 20-high cold rolling mills use 2E raw materials for reprocessing, and the mechanical properties, surface quality and 8K grinding efficiency of the final product will be greatly improved.
Yangjiang Hongwang uses advanced automation, information technology, and intelligent technology to achieve centralized control of the entire plant and “unmanned” operation of the production line, setting the production workshop into the industry’s “smart factory” benchmark. The smooth trial production of the second phase of the 500,000 tons of three-stand continuous rolling and continuous de-pickling combined unit will further improve the product structure and product quality of Hongwang Group in South China, and provide customers with better products and more Excellent and stable service.
