Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled A588 Gr A heavy plate products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the A588 Gr A heavy plate rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
Recently, the epidemic situation in developed countries such as Europe and the United States has become more and more serious, leading to the stagnation of economic activities in some countries, which has also affected domestic and foreign trade orders. In particular, industries such as steel, which have a long industrial chain and a wide range of industries, are more seriously affected. The development of foreign epidemic situation has different influence on the direct and indirect export of A588 Gr A heavy plate and so on steel products.
