Essentially, the substitution of scrap steel for iron ore means that the steelmaking process shifts from a long process starting with iron ore to a short process using scrap steel as raw material.
In the modern industrial system, steel strips, as a basic and key metal material, are widely used in multiple fields such as medical care, the aviation industry, automobile manufacturing, electronics and electricals, and tool cutting.
Medium and heavy plates are mainly used in construction engineering, mechanical manufacturing, container manufacturing, shipbuilding, bridge construction, etc.
Medium and thick plates refer to steel plates with a thickness ranging from 4.5 to 25.0 mm, while those with a thickness between 25.0 and 100.0 mm are called thick plates, and those with a thickness exceeding 100.0 mm are extra-thick plates.
To obtain the desired shape of the steel plate, it must undergo permanent deformation. The process adopted can be local or overall bending, deep drawing, tensioning, or a combination of these forming methods.
