Description

Rolling is a metalworking process that passes steel billets through the gap between a pair of rotating rolls, and the cross-sectional area of the material is reduced and the length is increased due to the compression of the rolls to form steel plates. This process represents the rolling of 1kg of continuously cast steel billets, corresponding to the production of 0.919kg of rolled steel plates. This process should be used in conjunction with production data for 1kg of continuously cast steel billets. The data originates from actual production processes of steel companies, aggregated from multiple steel enterprises.

Activity Description

The steel plate rolling process includes heating, annealing, rolling, cooling, etc. This dataset includes energy consumption, auxiliary material consumption, by-products or wastes generated, atmospheric emissions, and water emissions during the rolling process.

Process Description

Rolling is a metalworking process in which a steel billet is passed through a gap between a pair of rotating rolls. The material's cross-sectional area is reduced due to compression from the rolls, while its length is increased to form steel plates through pressure working. This process represents the rolling of 1kg of continuously cast steel billet, resulting in 0.919kg of rolled steel plate. This process should be used in conjunction with production data for 1kg of continuously cast steel billet.

Technology comment

Steel plate rolling refers to the process of plastic deformation of continuously cast slabs after being heated to a certain temperature through rolling equipment. First, the continuously cast slab is placed into a heating furnace, heated to an appropriate temperature to enhance material ductility. Then, the heated billet is fed into the rolling mill for rolling, where the material undergoes plastic deformation through the force applied by the rolls, altering its shape and dimensions. Finally, the rolled material is rapidly cooled via cooling devices to fix its internal structure, thereby improving the mechanical properties of the material.
