China has developed the world's largest wide and heavy plate mill, and the aircraft carrier steel plate is guaranteed. The world's largest and most accurate 5.5-meter wide and heavy plate mill with international advanced level, recently completed the final assembly and joint inspection at China Yizhong Group Co., Ltd., and will be shipped to the key steel enterprise - Angang.
According to experts, the wide and thick plate mill is mainly used for rolling large-scale military and civilian ship steel plates of more than 4 meters, high-strength large-diameter oil pipes, gas pipes, and special steel plates for nuclear power industry. Its successful assembly and manufacturing will help break the foreign blockade of China in the field of special steel, and will play an important role in promoting the country's oil and gas transportation, shipbuilding and national defense construction.
This heavy-duty mill with a rolling force of 10,000 tons was designed by Yizhong and the German SMS company, and was independently manufactured. This machine is the world's largest specification, the highest installed capacity, the strongest rolling capacity, the largest tonnage of single-machine equipment, and consists of more than 40 parts of more than 40 single machines, such as finishing mills and roughing mills.
The wide and thick plate mill manufacturing system is complex and large, with high precision requirements, and it is extremely difficult to manufacture. At present, only a few countries such as Germany and Japan can manufacture. The assembly of a 5.5-meter wide plate mill has been completed, reflecting the technological advancement of China's major equipment industry and the rapid improvement of a heavy manufacturing level.
