China has made a significant breakthrough in heavy industrial equipment by developing the world's largest and most precise 5.5-meter-wide and thick plate mill, which is equipped with international advanced technology. Recently, this state-of-the-art heavy plate mill completed its final assembly and joint inspection at China Yizhong Group Co., Ltd. and is now set to be delivered to Angang, one of China’s leading steel enterprises.
Experts highlight that this wide and thick plate mill is primarily used for producing large-scale steel plates for military and civilian ships over 4 meters in size, high-strength oil and gas pipes, and specialized steel plates for nuclear power projects. Its successful development and manufacturing mark a major step forward in breaking foreign technological blockades in the field of special steel production. This advancement is expected to significantly boost China’s oil and gas transportation, shipbuilding industry, and national defense capabilities.
The 10,000-ton rolling force mill was jointly designed by Yizhong and the German company SMS, and it was fully developed and manufactured independently in China. It holds the title of the world's largest specification, highest installed capacity, strongest rolling capability, and the heaviest single-unit equipment. The system comprises more than 40 individual machines, including finishing and roughing mills, making it an extremely complex and technically demanding project.
The production of such a wide and thick plate mill requires high precision and extensive engineering expertise. Currently, only a few countries, like Germany and Japan, have the capability to produce similar equipment. The completion of the 5.5-meter-wide plate mill assembly not only demonstrates China’s growing technological strength but also reflects the rapid progress in its heavy manufacturing sector.
This milestone underscores China’s commitment to achieving self-reliance in critical industrial technologies and its ambition to become a global leader in advanced manufacturing. With continued investment and innovation, China is steadily closing the gap and even surpassing traditional industrial powers in key sectors.
