Description
Rolling is a metalworking process where steel billets are passed through the gap between a pair of rotating rolls, undergoing compression that reduces the cross-sectional area and increases the length, thus forming steel plates. This process represents the rolling of 1 kg of continuous-cast steel billet, yielding 0.919 kg of rolled steel plate. This process should be used together with the production data for 1 kg of continuous-cast steel billet. The dataset is compiled from multiple data sources.
Activity Description
The steel plate rolling process includes steps such as heating, annealing, rolling, and cooling. This dataset includes energy consumption, auxiliary material consumption, by-products or waste generated, atmospheric emissions, and water discharges during the rolling process.
Process Description
Rolling is a metalworking process where steel billets are passed through the gap between a pair of rotating rolls. Due to compression by the rolls, the material's cross-section is reduced and its length increased, forming steel plates. This process represents the rolling of 1 kg of continuously cast steel billet, resulting in 0.919 kg of rolled steel plate. This process should be used together with the production data for 1 kg of continuously cast steel billet.

Technology comment
Steel plate rolling refers to the process of plastically deforming a continuous-cast steel billet after heating it to a certain temperature using rolling equipment. First, the continuous-cast steel billet is placed in a reheating furnace and heated to an appropriate temperature to enhance the material's plasticity. Then, the heated billet is fed into a rolling mill where plastic deformation is induced by the force of the rolls, altering the material's shape and dimensions. Finally, the rolled material is rapidly cooled using a cooling system to stabilize its internal structure and improve its mechanical properties.
