Description
Silicon steel hot rolled coils are produced through a hot rolling process, which involves heating steel billets and rolling them at high temperatures to achieve the desired thickness and width. The production process of hot rolled coils includes stages such as preheating, roughing, intermediate rolling, and finishing rolling, covering energy consumption, material consumption, waste treatment, and environmental emissions associated with the production process. This dataset is compiled from data sourced from multiple origins.
Activity Description
The production process of hot-rolled coils includes stages such as billet preheating, roughing, intermediate rolling, and finishing rolling, encompassing energy consumption, material consumption, waste treatment, and environmental emissions associated with the production process.
Process Description
Hot-rolled coil is a steel product produced through the hot-rolling process, in which a preheated steel billet is rolled at high temperature into a flat plate of a certain thickness. The main characteristics of this type of steel are its excellent ductility and toughness, making it easy to form and process in industrial applications. Silicon steel, also known as electrical steel, is a type of steel containing silicon (Si), typically with a silicon content of 1.0–4.5% and a carbon content below 0.08%. It can be classified into two main categories: grain-oriented silicon steel and non-oriented silicon steel. Hot-rolled silicon steel coils are produced through the hot-rolling process, which involves heating the steel billet and then rolling it at high temperature to achieve the desired thickness and width.

Technology comment
The hot rolling process involves heating the metal billet produced from the converter to its plastic deformation temperature at high temperature, typically above 1000 degrees Celsius. The heated billet is then continuously rolled through a series of rolling mill stands. Initial rolling adjusts the billet's width and thickness through roll gap settings, while subsequent intermediate and finishing rolling further refine the dimensions and surface quality of the resulting coil. The entire rolling process can be subdivided into stages such as roughing, intermediate rolling, and finishing rolling, ensuring the final coil achieves the desired mechanical properties and surface finish.
