China's large steel mills have used advanced continuous rolling mills since the 1970s. The rolling mills have adopted a complete set of advanced automatic control systems. The entire production process and operation monitoring are carried out by computer control, and the rolling stock is rolled simultaneously on several rolling mills. Greatly improved production efficiency and quality.
China's crude steel output ranks first in the world. The annual output of crude steel in the top ten iron and steel enterprises in China is more than 10 million tons. This year, steel restructuring has entered the fast lane, such as Guangdong Steel Group of Baosteel Holding, Shandong Iron and Steel Group, which is mainly formed by Shandong Jigang and Laiwu Steel, and Hebei Iron and Steel Group. However, in order to revitalize China's steel industry, we must take a refined road. Hot rolled coils and CRC are still stuck in the bottleneck of heavy production and light weight. The steel rolling industry must take the high-end route, the shipbuilding industry and the automobile manufacturing industry and the construction industry are booming, bringing opportunities to the rolling steel industry, but the price increase of ore brings new difficulties to the rolling steel industry in China.
In order to become bigger and stronger, the domestic steel rolling industry must constantly strengthen the series of steel billet quality, heating, roll control, coiling capacity, pickling and so on. In addition, heavy, double, heavy, and heavy heavy machinery must be used to explore high-precision rolling equipment. Domestic Baosteel, Anshan Iron and Steel, Wuhan Iron and Steel, Shougang Design Institute, Dongda, Beijing University of Science and Technology, Yanda University and other colleges and steel rolling research institutions should also strengthen the joint development with the steel group.
China's steel rolling industry is going to revitalize and the road is still very long.
